CSA Approved Norwesco Low Profile HD Septic Tanks

This tough low profile tank, introduced to the North American market in 2012, can be used as a CSA approved septic tank, holding tank, pump chamber, or cistern for non-potable water applications such as rainwater collection, stormwater management or fire protection. Heavy duty and rotationally-molded in one piece, it provides leak-free reliability. Furthermore, they come with the baffle wall and fitting holes already in-place, reducing installation time and effort.

Inlet and outlet tees and pipe seals are included and accept 4” PVC sewer drain piping. Two to 20” diameter access openings and lids accept Norwesco manhole extension, double-wall corrugated pipe and ribbed PVC pipe.

Native backfill materials can be used (absolutely no clay or water saturated soils) but a sandy gravel mixture is recommended. May be installed with minimum 6” to max. 36” of cover above top of tank.

Water filling these tanks during backfilling, while not absolutely required, is still highly recommended to properly bed the tank and hold it in place. The tank, manway assembly and piping should always be water tested prior to completely backfilling anyway. Tanks may be pumped-out when water table is at or below the bottom of the tank.
