Since 1973, Skaw® has been manufacturing and delivering seamed concrete septic tanks throughout the New Auburn, Wisconsin, area. Since then, we have diversified our products, including a patented seamless concrete holding tank. During that time, we developed concrete tanks that would not leak when the soil thaws out and is saturated with water.

With more than 40 years of our own research and development, we came up with these innovative solutions to ensure our customers have the best concrete tank products available. Our WS Series Seamless Concrete Tanks (Patent #9464451) can be shipped anywhere. Please call our existing number for delivery.
