A 1000 gallon low profile single compartment septic tank with a side inlet, for New York
The Norwesco 1000 gallon one compartment septic tank with side inlet, part number 40197, is a green polyethylene tank 127 inches long, 60 inches wide and 51 inches tall, weighing 352 lb empty. It is made at Norwesco's Owego, New York plant and Norwesco lists its state septic approval for New York. The side inlet is the reason to pick this tank over the end inlet version: when the sewer line from the house arrives from the side of the excavation rather than the end, a side inlet saves a bend and a length of pipe and keeps the grade. Low profile means the tank is long and shallow, so the dig stays short where rock, a high water table or a shallow sewer line rules out a deep hole. The whole 1000 gallons works as one settling chamber. Loose plumbing means the 4 inch gasket with tee assembly for the inlet ships with the tank for the installer to fit; the outlet is a 4 inch opening. Access is a 20 inch gasketed manway. Norwesco backs the tank with a 5 year warranty and sets the service limit at 130 F.

When the side inlet is the right choice
Sketch the lot before you order. If the house sewer leaves on a wall that faces the long side of where the tank will sit, the side inlet lets the pipe run straight in. If it faces the end, the end inlet version of this tank is the one to buy. Either way the outlet is at the far end and the drainfield line runs from there. A single compartment tank is the simplest design made; confirm with your county health department that a single compartment 1000 gallon polyethylene tank is accepted for your bedroom count and whether they require an effluent filter or a riser. Where two compartments are required, the low profile two compartment tank with side inlet is the same shell with a baffle. Our note on Norwesco IAPMO and CSA septic tank approvals explains what the listings cover, and the low profile tank field guide covers handling a long shallow tank on site.
Openings and fittings
- Inlet. A 4 inch gasket with a tee assembly on the side of the tank, shipped loose. The inlet tee turns the incoming flow downward so the scum layer stays undisturbed. The inlet sits higher than the outlet.
- Outlet. A 4 inch opening at the end. Tell us what your code requires at the outlet, a tee or an effluent filter, and we will put it on the order so the installer is not waiting on parts.
- Manway. A 20 inch gasketed manway for inspection and pumping. If the lid will finish below grade, ask us for the riser that brings it to the surface.
- Drawing. Norwesco's drawing, linked under Technical Drawing on this page, gives the side inlet position and the invert heights you need to set the pipe grades. Our inlet, outlet and vent tie-in walkthrough covers the rest of the plumbing.
Setting it
Follow Norwesco's installation instructions for this tank: they set the bedding, the backfill material and the order in which you fill the tank with water while backfilling so the walls are supported from both sides. Never backfill an empty polyethylene septic tank, and never set one where vehicles will drive. Level the bedding on both axes before the tank goes in. Fit the inlet tee, connect the pipes, fill with water to the outlet, and then call for the inspection.
