  • Septage disposal is not allowed between October 15 and June 1
    • Septage is the sludge produced in individual on-site wastewater disposal systems such as septic tanks and can be divided into three parts:
      • Scum, which floats to the top and contains fats, oil and grease as well as any floating solid waste
      • Effluent, which is the semi-treated wastewater that comprises the majority of the material in the septic tank
      • Sludge, the solids which collect at the bottom of the tank and where most of the bacteria live that are involved in the anaerobic degradation processes
  • Holding tank sewage is allowed to be disposed year round
    • Sewage is household and commercial wastewater that contains human waste from systems such as holding tanks and consits of:
      • Greywater (from sinks, tubs, showers, dishwashers, and clothes washers)
      • Blackwater (the water used to flush toilets, combined with the human waste that it flushes away)
      • Soaps and detergents and toilet paper

However, as per the Wastewater Disposal Vehicle License Policy Agreement between the RM of St. Clements and the licensed Waste Haulers. The RM of St. Clements Lagoons, East Selkirk & Grand Marais, will not accept septage from Septic Tanks between October 15 and June 1st.  This requirement is stipulated by the Environment Act License which is issued to each wastewater treatment facility.  This license can be accessed on the following public registry:    http://www.gov.mb.ca/sd/eal/registries/index.html

Please note that Manitoba Sustainable Development has identified an unwillingness to authorize septage disposal during this period.  Should any emergency situation arise, haulers are recommended to make arrangements with a nearby facility approved to receive septage during this period.  For further interpretation regarding sewage vs septage, please contact the RM of St. Clements or Manitoba Sustainable Development
