NWLCA

The Northwestern Lancaster County Authority (NWLCA) is a small water and wastewater authority supplying 668 drinking water customers and 1,456 wastewater customers in Penn Township. These numbers do not include 668 water customers in the southern part of the township which are supplied separately by the Manheim Area Water & Sewer Authority, and 51 water customers in the southern Fruitville Pike area which are served by the City of Lancaster’s public water system.

NWLCA's customer drinking water demand is roughly 140,000 gallons per day (GPD) with a permitted capacity of 504,000 GPD from two wells. The water system has a state-of-the-art water treatment facility, constructed in 2012, including membrane filtration, ion exchange nitrate removal, pH adjustment and sodium hypochlorite disinfection. A 500,000 gallon water tower provides volume and pressure to the distribution system. A booster station provides pressure to the 51 water customers in the southern Fruitville Pike area which are served by the City of Lancaster’s public water system.

Discharging into the Chiques Creek, the NWLCA wastewater treatment plant was originally constructed in the early 1990’s and upgraded to meet the demands of the growing community as well as new Chesapeake Bay Program initiatives in 2005. The upgrade included expansion to a four basin Sequencing Batch Reactor with dissolved oxygen control for biological nutrient removal, chemical phosphorus removal, aerobic digestion, influent screening, ultra violet disinfection, and sludge thickening. The wastewater plant’s permit hydraulic capacity is 650,000 GPD, with an average flow of 325,000 GPD from residential, commercial, and industrial customers. Six pump stations convey flows to the treatment plant. Since the upgrade, the plant has easily met the Net Total Nitrogen and Net Total Phosphorus mass load effluent limits set by the facility’s National Pollutant Discharge Elimination System Permit.
