WS Series Tanks

Learn more about why you should choose our WS Series Tanks for your projects.

One-Piece Construction

The WS Series Tanks are 2,000 gallon concrete, seamless cover joint holding tanks that are manufactured in a 2-step process. This process eliminates exposed joints. This tank will not leak, and features a 28″ leakproof inlet.

Water Stop Seal

The WS Series Tanks feature a water stop seal, which is embedded into the walls of the tank and into the cover of the tank through a 2-stage pour. This is poured-in-place seal to eliminate the possibility of leaking at the seamless joint.

Added Strength

The addition of interior support columns and a fifth wall in the center of the tank provides significant additional support for the tank cover, floor, and walls. This is designed to increase the strength and durability. The added strength extends the life of your tank.

Homeowners might not give much thought to the differences between pre-cast septic holding tanks until they have a problem. Make the right choice upon installation and choose the Skaw® Water Stop tank for your home or vacation property for extended life, better overall performance, and decreased maintenance.
