Norwesco 1000 Gallon Two Compartment Septic Tank with Two Manholes - Approved in Canada - IAPMO Certified

Where this tank fits

This is a buried septic tank for a house or a cabin whose system has been sized at 1000 gallons, in a jurisdiction that accepts Norwesco's Canadian approval. The yellow colour is how Norwesco marks the Canadian version in the yard; it is the same polyethylene as the rest of the line. Our note on single compartment versus two compartment septic tanks explains what the second chamber does for the drain field and when an inspector will insist on it, and the guide to Norwesco's IAPMO and CSA B66 septic approvals explains how the Canadian approval differs from the US listings, which is the thing to read before you buy this tank for a site south of the border. Confirm the tank size your authority requires for the bedroom count first; the tank sizing guide and the tank sizing calculator get you started.

At 63 inches tall the tank is a standard-depth body, not a low profile one, so it wants a normal excavation. A 1000 gallon tank holds 8340 lb of water when full, and like every polyethylene septic tank it is filled with water as it is backfilled so the walls are supported from both sides.

Openings and fittings: what to check before you buy

1. Manholes. Two 20 inch openings with 20 inch lids, one over each compartment. Decide the finished grade before the tank goes in; if the lids will sit below grade, ask us about risers at order time so they ship with the tank.
2. Inlet and outlet. No inlet or outlet fitting is listed with this tank. Tell us the pipe size your design calls for and we confirm what the tank arrives with and what the installer supplies before the order ships.
3. Which end is which. The inlet end sits higher than the outlet end so liquid flows through by gravity. Check the markings before you set the tank.
4. Approval. Norwesco's IAPMO listing and the Canadian approval are the documents the inspector wants to see. Ask us for them with the order.
5. Drawing. Norwesco's drawing for this tank is linked under Technical Drawing on this page and shows the opening positions and invert heights.

Sizes and versions nearby

One size up in the same Canadian two compartment line is the 1250 gallon two compartment septic tank, part 41746. If the job is a buried water or liquid storage tank rather than a septic tank, Norwesco makes the 1000 gallon multi-use underground tank for Canada, part 41736. Each page carries its own dimensions.

Shipping and receiving

The tank ships LTL under NMFC 156600-02, 102 by 60 by 63 inches and 328 lb, from the nearest of Norwesco's Lancaster, Ohio, Owego, New York, St. Bonifacius, Minnesota and Washougal, Washington plants. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. Two people can handle an empty 328 lb tank with straps, but plan a machine for setting it in the hole. At the tailgate, check the part number against 41724, look at both manhole rims for transit damage, and keep the lid seats clean. Bed the tank on a flat, compacted base, set it level, and fill it with water as you backfill.
