Meschutt Beach Wastewater Upgrade - P.W. Grosser Consulting, Inc.

Meschutt Beach Wastewater Upgrade

An upgraded sewage disposal system reduced the amount of nitrogen entering Peconic Bay by 65%.

PWGC was selected to provide professional engineering services to design an innovative on-site wastewater treatment system to replace the outdated sewage disposal systems at the park. PWGC was honored with a Diamond Award from the American Council of Engineering Companies of New York (ACEC-NY)—the organization’s highest honor—for this project, the region’s first commercial innovative alternative on-site wastewater treatment system (I/A OWTS).

As part of the project, the possibly of greywater reuse was evaluated; unfortunately, due to space and cost constraints, a greywater system could not be included. We designed and installed a new I/A OWTS to replace the outdated and underperforming wastewater treatment system at the waterfront park. This project presented several challenges; in addition to being the first commercial application of I/A OWTS technology in Suffolk County, the project was constrained by a six-month completion window and being located in an area with a high water table.

We met with representatives from Suffolk County’s Parks, Public Works and Health Services Departments to determine the best location for the proposed system; developed an in-depth engineering report, design plans and specifications for a County-approved I/A OWTS (in this instance using a system manufactured by Orenco), and developed an aggressive project schedule to be ready for the targeted opening of the park on Memorial Day Weekend 2016.
