Distribution System Gets A BoostSource: Arch Chemicals Inc.
The water plant filters, treats and delivers an average of 3.6 million gallons of water daily. In addition to providing water to the City of St. Joseph, the treatment plant sends approximately two-thirds of its treated water through a distribution system owned by the Southwest Michigan Sanitary and Sewer Water Authority. The system primarily serves Lincoln Charter Township, Royalton Township, and St. Joseph Charter Township. In total, the water plant provides water for approximately 33,000 residential, commercial and industrial customers.
As part of the contract agreement with the authority, the St. Joseph Water Department maintains the authority’s distribution system and the plant staff maintains the system’s booster pump stations and water towers.
The State of Michigan requires that water samples from remote taps must contain no less than 0.2 mg/L free chlorine. Residual chlorine in drinking water distribution systems serves as a sanitizing safety margin for preventing bacterial regrowth. To meet this stringent requirement, booster chlorination was initiated in the distribution system.
