Norwesco 200 Gallon Plastic Septic Job Shack Holding Tank with Low Profile Design in Black

The Norwesco 200 Gallon Low Profile Septic Holding Tank is a black polyethylene tank built for job-site sanitation and temporary holding where overhead clearance is tight. At 20 inches tall on a 48 x 60 inch footprint, it slides under a job shack or onto a trailer deck where a taller tank would not fit, and the 200-gallon working volume gives you meaningful capacity without a high center of gravity. Black resin blocks UV and discourages algae growth, which matters for a tank that sits outdoors through a build cycle. This is a holding tank that stores septic effluent or graywater for later pump-out, not an in-ground treatment septic system.

Will it work for your application

Size it against real demand before you commit. Plan for a full water weight of 1,668 pounds at roughly 8.34 pounds per gallon, and confirm the supporting deck, trailer, or pad is rated for that load plus the tank itself. Run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide so you match holding capacity to crew size and pump-out frequency, and design your platform or skid around the 48 x 60 inch footprint. If you cycle this tank between job sites, our guide on between-batch tank turnover and sanitization walks through the drain-rinse-inspect-sanitize sequence that restores a tank to clean service status before reuse.

Fittings and the mistake to avoid

The single most common error on low-profile septic tanks is assuming an approval or a fitting configuration that does not apply to your situation. Fitting, lid, and vent details are not specified for this listing, so confirm inlet and outlet size, lid type, and venting before you plumb it in. Call 866-418-1777 and we will confirm the exact configuration. Septic and holding-tank approvals also vary by state and by country, so verify what your local plumbing authority requires before you install. If you are specifying across the Canadian border, our guide on Norwesco IAPMO and CSA B66 septic tank approvals walks through how those listings map against US plumbing codes.

Freight

This 200 gallon septic holding tank ships LTL freight from the nearest Norwesco plant, either Shawnee, OK or Sheldon, IA, whichever is closer to your delivery ZIP. Because it routes from whichever of the two plants is closer, buyers across the central US and plains states get shorter LTL transit. Freight is quoted live per destination and is not included in the list price. Get an exact number with our Freight Cost Estimator, or call 866-418-1777 and we will route it from the closest plant to keep transit and cost down. The 20-inch low-profile height and 48 x 60 inch footprint make this an easy unit to deck-load and offload.
