Elementary Expansion

Pennsylvania school adds storm water management to comply with NPDES regulations

The Gladwyne Elementary School is a public school that teaches students ranging from kindergarten to fifth grade. It was originally opened in 1957, and today it operates as part of the Lower Merion School District in Montgomery County, Pa. Although the facility consists of 31 classrooms, the elementary school found itself unable to support anticipated population growth.

To alleviate this issue, the project lead recommended a multi-phase expansion of facilities. Initially, Gladwyne installed four provisional modular classrooms, but the facility was in need of a more permanent solution that would replace the temporary structure and expand on the existing infrastructure.

With a well-developed project scope, the architect, Gilmore & Associates, partnered with Chester Valley Engineers Inc. to prepare the site plans for submission. Since the project construction exceeded one acre of disturbance, it required a National Pollutant Discharge Elimination System permit for storm water management. To address space constraints associated with installing an aboveground storm water management system, the engineers turned to a trusted product that would provide subsurface storage: Brentwood’s StormTank Module.

During the installation of the 1,172-sq-ft system, Brentwood worked closely with the contractor, J and P Contracting, to provide onsite pre-construction guidelines. Brentwood also made staff members available to ensure that the project would run smoothly, despite the tight installation space. Designed as a seepage bed, the StormTank system provided the necessary storage capacity to meet the project’s requirements, and the Module’s application flexibility allowed the system to be installed in conjunction with the existing facilities and new construction.

Installed in the summer of 2014, the Brentwood StormTank system allowed the contractor to stay on schedule, and it completed the project prior to the beginning of the school year. In addition, the system allowed the engineer to propose a cost-effective solution for meeting strict regulations and provided the school district with an innovative expansion that will serve the Gladwyne Elementary School for years to come.
