Wieser Concrete Septic Tanks

Wieser tanks are easy to install and are manufactured in a controlled environment. The advantage of this is that all materials are inspected for consistent durability and quality. Wieser septic tanks are marketed to government agencies, municipalities, agricultural businesses and other commercial markets.


Wieser septic tank forms are available in a range of capacities from 750 gallon tanks to 40,000 gallon tanks. Container dimensions vary considerably based on customers' intended use. Larger tanks can be hooked together using connecting pipes. This allows the tanks to fill and empty using one inlet and one pump-out port.

Septic tanks feature upside down, low casting design with steel skins and framing. This form allows Wieser to produce single and dual compartment tanks with removable wall blockouts.
