Lake Ronkonkoma Wastewater Upgrade
PWGC designed an innovative on-site wastewater treatment system to upgrade the sewage system at Lake Ronkonkoma County Park

PWGC was selected by Suffolk County’s Department to provide professional engineering services to design an innovative on-site wastewater treatment system to replace the existing outdated sewage disposal systems at Lake Ronkonkoma County Park.

As part of the project the positive use of grey water will be evaluated to determine its viability. PWGC will review the park site with representatives of Suffolk County Parks, Public Works and Health Services to determine the best location for the proposed system. Once the preferred location is established, PWGC will develop the engineering report, design plans and specifications for the proposed wastewater treatment system approved for use.
