Northwest Ottawa Water Treatment Plant
The Northwest Ottawa Water Treatment Plant is operated and managed by the City of Grand Haven, which delivers safe, reliable and consistent drinking water to over 40,000 customers. The communities served are Grand Haven Township, Spring Lake Township and Crockery Township, the City of Ferrysburg the Village of Spring Lake and the City of Grand Haven, which make up the Northwest Ottawa Water System (NOWS).
Water is pumped from Lake Michigan and is pre-filtered through submerged infiltration beds located 12 to 15 feet below the lake bottom. When it reaches the treatment plant it is filtered again using a “direct filtration” procedure, passing water through 52 inches of anthracite coal. The water treatment plant is approved to filter and pump 23.25 million gallons per day.
