The Pascack 65 well upgrade will improve the water quality at the well site by removing entrained air.  At certain pump rates and aquifer levels, air is entrained into the water, periodically reducing overall capacity.   Pascack 65 well is located in Clarkstown, off of Pascack Road.

United Water New York (UWNY) investigated the possibility of utilizing Liqui-Cel Membrane Contactors which incorporate a hydrophobic polypropylene membrane to remove dissolved gasses from water. Water flows on one side of the membrane and a vacuum or strip gas is passed on the other side of the membrane. By controlling the pressures of gases in contact with the water, a highly efficient method for gas control can be achieved.

Buck, Seifert & Jost, Inc. (BS&J) assisted UWNY in the permitting for the overall project which includes the Liqui-Cell membrane system, new chemical feed pumps, and electrical system upgrade.  The system will be enclosed in a new approximately sixteen (16’) feet x twelve feet (12’) single story masonry structure addition.  Specifically, BS&J was involved in the permitting with the NYSDOH, RCDOH, and Town of Clarkstown Technical Advisory Committee and Planning Board.
