We call our listed tanks, Pinnacle Tanks. They are recognizable because the lid is cast onto the body, eliminating the gasketed lid seam. Pinnacle tanks are water tight and are water tested at the plant. Interceptors and clarifiers are always H20 traffic rated assemblies. Single tanks are made in sizes from 750 gallons to 3,000 gallons. Multiple tank systems are also available. The design is adaptable to almost any application and we are interested in the special requirements surrounding any of your projects.

A standard septic tank line is also available for applicable residential projects. There are both the seamless water tight design and also the Tom’s gasketed lid design which you may have ordered in the past.

The Chapin Pre-Cast product list also includes tank accessories and primary and secondary treatment systems which can be utilized to meet special construction specifications, new regulatory requirements and to take advantage of newly available technologies.
