Infiltration Gallery Installation




New Jersey

Completion Year



RENOVA was selected as the implementation contractor for the installation of a groundwater treatment infiltration gallery at an industrial property. RENOVA constructed two (2) infiltration galleries, each approximately 65′ by 75′, consisting of nine (9) Lane Storm Keeper storm water chamber runs and 12” corrugated HDPE manifold piping. Following the installation of the gallery components, the area was backfilled with #57 stone, three feet of reused fill, topped with six inches of imported topsoil, and hydroseeded. RENOVA then connected the infiltration galleries to a newly constructed groundwater treatment facility. RENOVA provided value engineering by recommending spooled piping to penetrate through the treatment facility foundation, thereby averting a construction delay. The recommendation was a success and the foundation pour was completed on schedule with no redesign necessary to install piping.

In total, RENOVA installed over 1,000 linear feet of 6” SDR 11 HDPE and schedule 80 PVC force main from the treatment facility to the infiltration galleries. In addition, RENOVA installed two (2) 2” HDPE conduits and four (4) handholes within the force main trench, which crossed under existing utilities including an electrical duct bank. RENOVA provided connections from the existing HDPE influent pump system and final connections to the new water treatment plant for the effluent pipe. The connection for the existing influent pumping system also consisted of 3” primary with 6” secondary HDPE piping and reconnection to an existing 6” PVC secondary effluent system. Restoration included 1,800 square feet of asphalt paving, grading, and hydroseeding of the trench line. RENOVA completed the work with zero reportable incidents, on schedule, and within budget.
