Water treatment process

HINCKLEY SURFACE WATER TREATMENT PLANT: Redlands has awarded an $8.5 million contract for improvements to the Hinckley treatment plant so that it can produce drinking water that meets federal EPA standards. The city will save about $10 million from the 2006 construction estimate of $18 million. 1 INTAKE 2 FLOCCULATION BASINS 3 FILTRATION BASINS 4 DISINFECTION 5 STORAGE Water flows into the Hinckley plant from the Santa Ana River and the State Water Project aqueduct. 2 Water moves slowly through the basin and over inclined plate settlers, which encourage sediment to coagulate and fall out. 3 Water flows through V-notch launderers, causing more material to settle, then flows down through filters. 4 The water leaves the plant through a pipeline, where chlorine is added to disinfect it. 5 The water moves into the city's Agate Reservoir, where it will flow slowly around baffles to give it more contact time with the chlorine before it is delivered to customers.
