Water Plant

Water Treatment removes contaminants and undesirable components or reduces their concentration so that the water becomes fit for its desired end-use. The main goal of the Town's Water Treatment Facility is to consistently and reliably provide our residents and customers with clean, safe drinking water. 

Technically speaking, this is achieved by pulling water from the Warrenton Reservoir and treating it with specific disinfecting chemicals, it will then be evenly distributed through flocculation and sedimentation basins. This step in the process allows for suspended particles to settle out of the water. After the sedimentation stage the water is filtered through two high flow rate granular activated carbon filters before finally being treated with a final dose of disinfecting chemicals. Throughout this process the Water Treatment Facility is able to remove undesired tastes, odors, harmful bacteria and pathogens; ensuring the water provided is safe for all consumers. 

Town of Warrenton Water Filtration Plant: Built in 1983 with a 2.0 MGD (million gallons per day) capacity. Filtering rate at 2.0 g/m/ft2. Granular Activated Carbon for taste and odor control. 

Upgraded in 2005 to 2.4 MGD capacity.

Upgraded in 2011 to 3.2 MGD capacity. Limited by the 2.3 MGD Safe Yield of the reservoirs, but enables the plant to function at a high level during emergencies and to keep staffing levels down with future growth. 

Upgraded in 2020 with a new Chemical Delivery Building. This new building operates with state-of-the-art electronics and flow-based chemical delivery pumps that are capable of delivering the optimal doses to help ensure and maintain the highest level of drinking water quality.
