Lakewood Water Hardness & Quality Report (2026)

The Lakewood Water District serves the city of Lakewood in Pierce County, Washington, providing drinking water to residential, commercial, and industrial customers across approximately 24 square miles. The utility sources all of its water from local groundwater wells tapping into glacial aquifers beneath the Puget Lowland. Key facilities include multiple production wells and a central treatment plant employing disinfection and filtration processes. The district is located at 11900 Gravelly Lake Drive SW, Lakewood, WA 98499, and can be contacted at 253-588-4423 for inquiries.

The watershed for Lakewood's supply is the local groundwater recharge area within the Puget Sound basin, fed by precipitation infiltrating through glacial outwash plains and forested uplands. The dominant geology consists of Pleistocene-age Vashon glacial till, advance outwash sands and gravels, and recessional deposits forming confined and unconfined aquifers. These unconsolidated sediments contribute to a soft water character, as rainwater percolates through silica-rich sands with minimal contact with hardness-inducing carbonate rocks, yielding water low in dissolved calcium and magnesium.

With a soft water profile, Lakewood's supply poses minimal risk of scale buildup in pipes, water heaters, and dishwashers, reducing maintenance needs and extending appliance life. No water softener is required or recommended, as the low mineral content avoids the spotting on glassware or reduced efficiency seen in hard water areas. Routine flushing of fixtures suffices for upkeep. The district's water quality report earns an A grade, meeting all EPA health guidelines. Water undergoes disinfection with hypochlorite, filtration, and pH adjustment to reduce corrosivity, with compliance maintained for the lead and copper rule via corrosion control.
