Henderson Sewer Connection

May 30, 2023, Construction begins for the Low Pressure Sewer Services along the Henderson Catchment Area!

Construction crews have mobilized and began installing low pressure sewer services to all properties who have registered for connection either by paying cash or participating through the Local Improvement District. Work is progressing from the southern portion of the eligible area northward. Property owners on municipal roadways will be contacted by Southwood Ventures directly as construction approaches their areas to discuss locations for the curbstops along the frontage of their property. Property owners along Henderson Highway have already had locations for their curbstops identified earlier this year to allow for permitting with Manitoba Transportation and Infrastructure as Henderson Highway is a provincial right of way.

Once a service and curbstop are provided to a property the system is ready for private hookup and use. Homeowners are responsible for connecting their private system to the municipally provided curbstop. Before work on private property is backfilled, an inspection of the connection must be arranged with the RM office by calling 204-482-3300 with a minimum of 48 hours’ notice. Once an inspection and sign off are completed, the sewer service will be activated and the quarterly utility billings will begin.

There is still some available capacity for additional low pressure sewer services in the Henderson Catchment Area. Anyone not already registered but interested in connecting at this time would be responsible for the 2023 connection fees and buy in rates as set out by by-law in the amount of $14,588. We can be reached by calling our office at 204-482-3300 or by emailing info@rmofstclements.com.

January 9, 2023 Update

Over half of the currently available municipal sewer conveyance capacity in the RM of St. Clements Henderson Catchment Area has been reserved! The Henderson Catchment Area is known as the area between the Red River and the CEMR railbed from the Old River Road area north to Lockport is within the Red River Corridor and has been prohibited from installations of both new and replacement septic systems due to the sensitivity of the area. There is now available municipal low pressure sewage treatment capacity in this region for those new to the area, those who face aging or failing private on-site septic systems, or anyone ready to transition to a more environmentally friendly way to treat wastewaters.

The municipal contract for installations of service line extensions terminating at a curbstop located at participating property lines has been awarded to Southwood Ventures Inc. and work will commence in Spring 2023. Only those who have voluntarily enrolled for the HCA sewer presale will have curbstops installed. The first properties to receive their curbstops will be those who have paid cash in advance, followed by those who are paying via the Local Improvement District levy subject to the approval of the Municipal Board. Anyone not wishing to participate in the pre-sale at this time will not be affected.

Open Houses are scheduled at the Narol Fire Hall on January 30th and February 9th at 6:30pm and everyone within the catchment area are encouraged to attend.

A Public Hearing is scheduled for Feb 21, 2023 at 6:30pm at the Municipal Office for anyone paying via tax levy through the Local Improvement District.  Property owners will receive formal notice of the Public Hearing in the mail along with a connection agreement. Property owners who wish to be entered onto the LID and who have not yet signed a connection agreement must return a signed copy to the RM office by no later than February 15th, 2023. 

Property owners are responsible to make the connection from their private systems to the low-pressure sewer curbstop, and are encouraged to reach out to qualified contractors to obtain a minimum of three relevant quotes specific to their property and set up. Installation requirements can be found here. The municipality has extended the date for which properties participating in the presale to connect their dwelling to the curbstop an additional year now to July 1, 2026. Frequently Asked Questions can be found at the bottom of this page. 

Property owners fronting Henderson Highway will be contacted in advance of the work to determine the preferred location of the curbstop. This is being done in advance of the installations so application and approval can be made to Manitoba Transportation & Infrastructure before the work begins within the provincial right-of-way. Participating properties fronting municipal rights of way will be contacted for their preferred location as the work progresses shortly before work commences.

If you wish to participate in the HCA sewer connection presale at the current connection fee before the cost increases, contact our office by email at info@rmofstclements.com or by phone at 204-482-3300.

November 2, 2022 Update

Unfortunately, due to multiple start and stop events related with this project, heavily impacted by the excessive rain and saturation of the soil experienced this year, resource shortages, and delays in infrastructure projects province wide our project schedule has been unpredictably extended beyond any reasonable expectation of our project management team. This has resulted in a delay of private property curbstops installations to commence in spring of 2023 instead of the previously advertised fall of 2022. We know this is not what our ratepayers wanted to hear and we apologize, but the weather has not been cooperating with us this year.  We all share in this frustration. 

The seasonal start up predicted to commence forcemain installation in spring 2022 was delayed until mid September 2022, the originally anticipated completion for this portion of the project. While the forcemain installation delays unfolded, planning and issuing the Tender for the installation of curbstops to participating properties had its own set of challenges. Our intent was to have our Tender for the installation of the curbstops to the property lines complete before the final connection of the foremains to the system, so that the municipal system was prepared to accept the wastewaters.  With delays in forcemain construction, which now has a revised schedule to complete by end of November 2022, we also had delays in going out to tender for curbstops as we needed to provide some relatively accurate dates of when the contractors would be able to begin.  We published a tender that closed in early September which requested installations to occur in the fourth quarter of 2022.  This Tender did not produce a competitive bid process for our ratepayers.  It should be noted that contractors are limited with resources to deliver in the timeframe we had identified.  We discussed this with Council and reissued the Tender with more reasonable installation dates and identified the installation to occur in the spring and summer of next year.  The Tender closed by the end of September and the results shared with Council. The Tender was awarded to Southwood Ventures on October 18, 2022. 

We also know there may be some potential emergency installations identified by some residents and they will be evaluated in a fair manner with discussions with the Province of Manitoba to determine if we need to do those curb stops this year and will work with those residents directly.  As you can appreciate, we can not do this for everyone and will be evaluating it on a set of criteria (that we are developing) that could be applied in a fair and transparent manner, as the resources to complete them are very limited.

Council provided direction to begin the process for the Local Improvement District By-law in June 2022 as an alternate payment option for property owners. Our staff are continuing to work on this and we had hoped to have the Local Improvement Plan available for Public Consultations this fall but it requires having detailed costs related to installation of the curb stops available.  This will be in place before the curbstop installations in the spring 2023.

Our goal has not changed, to get this project done as soon as possible, but we have had to adapt to very unusually difficult year.

We are excited that this long-awaited project is coming to completion soon but unfortunately, we will be waiting till this spring to commence private property curbstop installations.

Exciting Opportunity for the Henderson Catchment Area

New sewage infrastructure is an important part of the RM’s commitment to protecting the health of our natural environment and our residents, both for today’s St. Clements families and for future generations. Allowing property owners the opportunity to connect to the Henderson catchment area sewer system will assist in the transition away from septic fields to more environmentally friendly ways of managing household waste. The provincial government has prohibited both new and replacement septic fields in the Red River Corridor, due to the sensitivity of the area and the harmful substances they can expose. In addition, the sewer system will improve home resale value and will greatly reduce how frequently holding tanks will need to be pumped out, in turn saving you the cost of regular pump outs.

Taillieau Construction will be installing two sewer lines that will be pushed from the Lockport Treatment Plant to the lagoon in East Selkirk. Soon businesses and homes interested in the service along Henderson Hwy, from the Old River Road area north to the Lockport Business area will be able to take part in our sewer connection presale. This includes all roads west and east (up to the railway tracks) of Henderson Hwy.

If you buy into the municipal sewer collection system, the RM will ensure the service is brought to your property line and terminate it at the curbstop located at the property line. We anticipate to install the service lines and curbstops in Fall 2022. The property owner would then be responsible for all work on private property.

In addition to the payment in full option, we are also evaluating a LID payment option for residents within the catchment area. This will allow property owners to buy into the system and repay the borrowed amount over a 20 year term as an annual property levy amount added to property taxes.

The deadline to participate in the LID or make payment in full will now be May 31, 2022. Those residents that wish to voluntarily participate in this presale opportunity will be expected to connect to the system by July 1, 2025. The reason for this set connection date is due to it being a voluntary option to hook up.

A reminder that the presale will be on a first come first serve basis until the end of May 31, 2022 or until all the 290 REU’s are presold (REU – is typically one household. This does not mean that we have 290 connections available).

If you wish to participate in the sewer connection presale by either payment in full or the LID payment option, please contact or visit our office to arrange payment and sign the connection agreement.

May 2022 Information Session

On Wednesday, May 25 we held two information sessions, one at 2:00 pm and the other at 6:00 pm to provide more details on the possibility of the option to add the amount owing to taxes as an LID. This was offered to both in person attendees as well as virtually on ZOOM.

You can view the presentation slides from the Information Session here.

Pipes were installed along Henderson Hwy from Old River Road north to Lockport, which connect via a pump at the Donald Lift Station to the Lockport Wastewater Treatment Plant. Homeowners in the Old River Road area had been under a provincial Health Order for 13 years before that new sewer line was installed and operating in 2018. These were among the first homes to benefit from sewer in the area as a permanent solution was created to a significant human and environmental-health challenge that had persisted for years. In 2017, a feasibility study was completed on expanding capacity for the Henderson Catchment sewer. This was completed due to the Lockport Treatment Plant reaching capacity with the 40 homes presently hooked up from the Old River Road area and could not service the remaining 500+ existing homes in the area. At almost 30 years old, the Lockport Treatment Plant is an aging facility that uses older technology. The cost to upgrade the plant was too large and it was determined that the best option was to connect to the East Selkirk Wastewater Lagoon, as the cost to put the lines in from Lockport to East Selkirk had the lowest initial capital costs out of the options and minimizes operational costs and utility bills, as well as it is easier to manage and operate.

About the East Selkirk Lagoon:

  • Currently has a capacity to treat wastewater from about 850 more homes
  • Was completed in 2015
  • Has few residences nearby
  • Underwent a lengthy environmental impact assessment before construction
  • Undergoes regular, rigorous environmental testing
  • Conforms to all current provincial environmental regulations
  • Meets nutrient requirement levels for Lake Winnipeg, which are the most stringent they have ever been

Benefits and considerations

Typical system used in low-density areas

The type of low-pressure sewer system being installed along Henderson Highway has been used throughout Manitoba for several decades and is most commonly used to service existing low-density developments such as the Henderson project area.


The primary benefit of a low-pressure sewer is the substantially lower cost to the property owner. Compared to the gravity-fed sewers found in cities, a low-pressure sewer is significantly more affordable when servicing a lower-density area.

Minimizing disruption to traffic, trees and landscaping

The second benefit is that low-pressure system pipes can be installed using a tunneling method that requires minimal excavation; this minimizes disruption to roads, utilities, trees and landscaping.

Requires pump installation A low-pressure sewer requires the property owner to install and maintain certain equipment, including a new submersible pump to bring household wastewater from the home to the sewer connection at the property line. The property owner is responsible for this equipment, which is normally installed at the time of connection to the sewer line.

What to expect

For most homeowners, the sewer system will connect to existing septic systems. The main change to the homeowner’s system will involve installing a pump in the septic or holding tank, and running a service pipe to the sewer connection valve at the property line. If you have a two-cell/dual-compartment septic tank in good condition and shown to be water-tight, it will be compatible with the new sewer system. If you have an older tank, you may be required to have a new septic tank installed. Holding tanks in good condition can often be converted into a compatible two-cell tank. If you currently have a septic field, it will be disconnected from your septic tank and left as is. The liquid that was being discharged to your septic field will now be pumped to the East Selkirk Lagoon.

Cost to homeowners

Those participating in the Sewer Connection Presale for the Henderson Catchment Area and voluntarily connecting to the sewer system, will be responsible for three different types of costs. 

1. Your share of the public infrastructure cost (includes one connection fee and curb stop)

Option 1. One-time payment in full – $14,588 (2023 fee)

This cost is on a first come first serve basis until February 2023 or until all the 290 REU’s are presold.

Note: This rate was determined at the time that By-Law 19-2016 was passed. This fee cannot be guaranteed once this presale becomes unavailable due to higher construction costs and ongoing infrastructure expansion.


*NEW* Option 2. Choose to have the infrastructure cost added to your tax bill as a Local Improvement District (LID) over 20 years – estimated at $16,302 plus additional interest

The above amount is an estimate and option that will be based on the result of sufficient potential taxpayer interest and approval by the Municipal Board on conditions acceptable to the RM. The total cost of this will be based on actual costs determined in the tendering process and will also include interest added over the 20-year period which will be determined in the project borrowing.

Update: As of February 2023 Option 2 is no longer available.

Municipal Act, S 311 – a local improvement may be any project the cost of which includes a capital component including sewage, water or waste management facilities, highways or drainage systems, which may be provided to all or part of the Municipality.

Municipal Act, S 315 (2) – the estimated cost of the local improvement includes:

  • All capital costs to be incurred for the purpose of the improvement, including the cost of acquiring land that the council considers necessary for the improvement

Municipal Act, S 316 (1) – local improvement or special services taxes must be calculated on the basis of one or more of the following:

                        (f) an amount for each parcel of land

2. The cost of the work on your property to connect your dwelling to the sewer curb stop that the RM installs at your property line – estimated at $4,000-$15,000

Homeowners are responsible for the installation and maintenance of the required equipment on their side of the property line. Please note that this cost is determined by many different variables, such as the type of system and the age of that system. As well as there could be challenges on the property such as underground services or distance to the home that makes pushing the pipe more complex. The best way to determine your costs is to contact an approved contractor.

Note: The RM installs only up to your property line.

3. Your share of the cost to operate the system – $198.78 per quarter

Once your household is hooked up to the system, you will receive a quarterly bill for your use of the system. The quarterly bill includes the following amounts set out in By-Law 9-2012 .

Quarterly Customer
Administration Fee
Minimum Quarterly
Sewer Charge (1.0 REU)
Total Quarterly Sewer Bill$198.78

Getting your property ready

As you prepare to hook up to the new sewer system, your contractor will be an extremely helpful source of information. Your qualified contractor can help you determine the work required and costs for that work, as well as making sure all requirements including inspections are met.

It is important that the contractor you hire has the right training and experience for the work so that they can ensure your side of the property is prepared to connect properly for a seamless transition to hooking up to the sewer system.

Hook-up Procedure

  1. Ensure that you receive specifications for installation from RM (available below)
  2. Choose your contractor and provide them with the list of specifications and requirements for the works done on your property
  3. Contact our Public Works department a minimum 48 hours prior to inspection before your contractor begins works. You can contact the office by email or by phone at 204-482-3300 to schedule an inspection
  4. If further inspection is required, Public Works will let you know
  5. Once Public Works confirms that works have been completed to our specifications, we will turn on to connect the system
  6. Once the system is turned on you are now ready to begin using your new sewer system, billing would start at this time

Frequently asked questions

Throughout this project we anticipate citizens will have questions and we are committed to providing a timely, considered response to all queries we receive. As questions are received, we will answer them on this webpage so that citizens can see what others are asking, and understand the answers that are provided. We won’t attribute questions we receive, and if we are asked the same question by more than one person, we will let you know where it may have already been answered.

If you have a question, please review the information below.

The System

How will the system work?

In terms of connection it will be a seamless process, most people currently have a tank that they are using, the only change you will find is that a pump will be put into your holding tank/septic tank and from that tank it will be pumped to the main line which will flow to the East Selkirk Lagoon. In terms of works, there are already sewer lines along Henderson Hwy as well as lines along the west/east roads (for east roads lines run up to the railway tracks).

What type of sewer is installed?

Consistent with the approach taken in other communities with similar population density and land usage, the Henderson project will be a low-pressure sewer. Low-pressure systems are used in less-populated areas such as rural or exurban environments, or in areas where development already exists. For example, around the City of Winnipeg most of the exurban areas like Headingley, LaSalle, Sandford, St. Francis Xavier, Stony Mountain, all have a low pressure sewer system. 

The benefit of a low pressure sewer system is that it is laid fairly flat at the same grade below ground so that it is less expensive to install the system, which then benefits as it is a system that works and is also affordable. 

Sewer Service Area

Which properties can connect?

Most interested businesses and/or homes along Henderson Hwy from Coronation Road north to the Lockport Business area, this area is known as the Henderson Catchment, can connect to the system. Included are all roads in the mentioned area that run west and east of Henderson Hwy, up to the railway tracks.

I own property east of the tracks. Can I hook up?

The priority focus of the current project area is water protection. As such, the current project area includes those properties that are closest to the river. The area between the river and the rail line is also sufficiently populated to make permanent sewage infrastructure feasible. In the future there may be opportunities to extend the sewer line to accommodate additional properties, should population density and the processing capacity allow. At the current time, however, the project area includes only the area between the river and the rail line.

I do not live in the Henderson catchment area that is available for hookup. Will my property be affected?

There is no requirement for homeowners outside of the Henderson catchment to connect to the new service and no part of the Henderson sewer project is being paid by general tax revenues or homeowners who are not hooking up.


Do I have to hookup to the system if I am in the sewer service area?

No, this is currently a voluntary option for those in the area.

What date must I begin using the sewer system?

Residents that pay for the presale connection have up to three years to complete the necessary work on their property and start using the sewer system by July 1, 2026.

What if I do not connect from my property to the curb stop by the specified date?

After July 1, 2026 those that have not completed the works on their property to connect to the curb stop will be charged the base PUB minimum rate which is $198.78 per quarter as per By-Law 9-2012 .

Why is there a set connection date for this area?

The reason for the set connection date is because this is a voluntary option to connect. Other areas in our Municipality with sewer/water were given a longer period of time to connect because it was mandatory.

I own more than one property and want to connect. Will I pay more?

The connection costs are per lot. If you were to subdivide a property into multiple lots, a connection fee would be paid for each serviced lot.

I have paid the connection presale in full, what is next?

We have awarded the contract for the municipal portion of the work to commence in Spring 2023. Those who have paid cash will have their curbstops installed first, followed by those entered onto the LID.

What if I decide I want to hookup after the presale?

If the 290 REU’s are not full after the presale you will still have the opportunity to connect to the system. Please note that the cost for connecting will most likely increase.

What if I am told after the presale that all the 290 REU’s are full but I still want to hook up?

We are constantly working towards expanding our sewer and water infrastructure. After the 290 REU’s are full, the next phase of the project would be to decommission the Lockport treatment plant so we can expand capacity and offer more hookups by constructing a new regional pumping facility.


How much do I need to pay to connect?

You have several options for payment of the public infrastructure costs. Our goal is to provide our residents with the most convenient and realistic options for making payment, therefore we are now looking to offer a new second option that may allow for more financial ease.

Payment Option 1

Come to our office to pay the infrastructure cost in full of $14,588 (2023) with debit, cash or cheque.

Along with the payment we will have an agreement for you to sign.

Please keep in mind that there are additional fees to the homeowner including cost of the work on your property and an ongoing utility bill.

*EXPIRED* Payment Option 2

Express interest that you are interested in having the infrastructure cost added to your tax bill as a Local Improvement District (LID) over 20 years. If you choose this option, please contact or visit our office to arrange signing of the connection agreement.

What does the presale cost include?

This includes the connection fee and the curb stop. The RM installs only up to your property line.

What are all the different types of fees I should be aware of?

  1. Connection fee & curb stop: Dependent on the payment option you choose either: $14,588 (payment option in full FOR 2023) or an estimated $16,302 plus additional interest (LID option)
  2. Cost for work on your property: estimated $4,000-$15,000 (contracted and covered directly by property owners) All work required on the homeowner’s own property (to connect their homes to the main sewer line) must be contracted, and costs paid, by homeowners directly. Although the RM will inspect each connection to ensure it conforms, homeowners are responsible for the installation and maintenance of required equipment on their side of the property line.
  3. Ongoing utility bill: $198.78, billed quarterly

When is payment for the connection presale due?

Payment in full for the connection presale is due by February 15, 2023. Those that we received payment first will have their spot guaranteed.

How long is this price guaranteed for?

The price will be for the first 290 REU’s or until February 15, 2023, whichever is sooner.


What type of contractor should I call about having the required equipment installed on my side of the property line?

Low-pressure sewer systems are common in Manitoba and there are many contractors that deal with sewer services and will be qualified to install the piping, pump and related equipment needed to connect your home to the new sewer system. As with any project, the RM recommends that property owners receive several written estimates from prospective contractors.

Which installers would you recommend?

We cannot recommend a specific contractor but we have compiled a list of contractors licensed by the City of Winnipeg that are qualified to do the works in the RM or as otherwise approved by the RM of St. Clements. You can download a List of Contractors here.

The RM of St. Clements does not guarantee, and does not accept any liability or responsibility for work performed or other actions taken by licensed contractors.

Who is liable for the install?

You will have your own preferred contractor do the installation on your private property. The agreement that you sign with the RM will leave all liability with the property owner.

What about impacts on landscaping on the homeowner’s side of the property line?

Because the equipment and pipes connecting your home to the new sewer are located underground, there will be some disruption to your property when the installation is performed. Your local contractor may be able to use horizontal tunneling to install the piping, which would limit the disruption to existing landscaping.

I am ready to begin construction on my property to connect, what is my next step?

Firstly, you should ensure that you are aware of all the specifications and requirements, if not, please contact us. You would then make arrangements with the contractor of your choice. When you are ready for the contracted works on your property to begin, please contact us to arrange an inspection. We would then go out for a pre-hook up inspection to make sure that the equipment on your property has been properly prepared, note details or indicate anything outside of specifications.

Is there any permit required from the RM for the install work?

Yes, we do have a sewer permit. There is no charge for this and it includes an inspection by Public Works to make sure that the work is being done to specs so that you can have the best possible system installed.

What factors will determine equipment costs on my side of the property line?

Costs will vary depending on the specific requirements of each property, such as the distance from the home to the property line and whether an existing septic tank will be compatible with the new system. Two-cell tanks in good condition and shown to be water-tight will be compatible with the new sewer. Holding tanks in good condition can often be converted into a fully compatible two-cell tank. If you have an older tank you may need to have a new septic tank installed.

Specifications and Requirements

What are the specs?

Click the link below to take you to our complete specification package.


Do I need to do anything if I do not want to connect at this time?

If you choose to not connect at this time and pay for connection in the future at a new rate, you do not need to notify us.

Note: Those that choose to not participate will not be impacted by the LID on their taxes.

Will you be providing water service?

At this point there is no plan to provide water service for this area.

How will I be billed for sewage usage once hooked up?

The current Lockport rates for 1 REU is $198.78/quarter.

What if I sell my property after paying the fee to connect?

If your home is sold before it is connected, the new owner will have until the designated date of July 1, 2026 to connect.

After I’m connected to the new sewer will I still need to have my septic tank pumped out? How often?

The new sewer system will carry liquid waste to the East Selkirk Lagoon. Solid wastes will be collected in your septic tank and will be pumped out approximately once every 12-15 months, depending on volume of use.

I would like to participate in the connection presale, what are my next steps?

Option 1: If you choose payment in full, you are now able to come to our office to make payment and sign the connection agreement.

Option 2: If you would like to add the amount to your taxes as an LID, please contact or visit our office to sign the connection agreement.

Is there still available capacity for additional hookups?

As of October 2022 there is still some capacity available for properties wishing to connect to the system, at a first come first serve basis. Please contact our office at 204-482-3300 so we may verify this and explain the options available at the time.

If I have paid cash for the pre-sale and change my mind can I get a refund?

While currently the connection to the system is voluntary due to capacity limitations of each phase of the project, within the next few years there will be expansions to facilitate connections to all the properties in the HCA. These expansions come with capital investments that each property benefitting from will pay their proportionate share of. This means, in all reality, the cost to hook up to the system in the future will continue to rise and the best value for money will be the earlier connections to the system.
