Project Description

The Municipality of Bethel Park is situated in the southern hills of the Pittsburgh metropolitan area in Allegheny County. In 1996, the Bethel Park Municipal Authority partnered with Chester Engineers, Pittsburgh, PA, to design a project for a 3.0 MG flow equalization basin. This tank was necessary for regulating the wastewater treatment plant’s flow rate during times of heavy rain. After researching available options, the project team specified an AWWA D110 Type III prestressed concrete tank because of its long-term durability and low cost of maintenance. Preload, which has designed and constructed prestressed concrete tanks since the 1930’s, was selected as the preferred tank builder.

This Preload flow equalization basin has an inside diameter of 140’ and a side water depth of 24.5’. Now entering its third decade of reliable service, this durable Preload tank will serve the residents of Bethel Park for many decades to come.
