Describe your Drinking Water SystemThe Dorchester Drinking Water System consists of 9 ( nine) groundwater wells. The raw water from the productionwells passes through a treatment system consisting of clear-wells, a chemical feed system, filtration system,ultraviolet disinfection, storage reservoirs, and high lift pumps. Operation of the treatment system is controlled basedupon the liquid level condition within the elevated water storage tank in the village of Dorchester. The SCADA

system indicates to the water treatment facility PLC when treated water is required to be pumped into the distributionsystem. During periods of low demand, the treatment system remains in the ready mode.

The distribution system consists of approximately 51. 3km of water main contained within the urban boundaries of thevillage of Dorchester.

List all water treatment chemicals used over this reporting periodSodium Hypochlorite 12%

Describe your Drinking Water SystemThe Thomdale Drinking Water System consists of 2( two) groundwater wells, a treatment system, reservoirs, and anelevated water tank. There are approximately 12. 1 km of watermain supplying water to the Village of Thomdale.

Raw well water is chlorinated before it enters into a 31 m3 contact chamber with concrete baffles to achieve thenecessary contact time. Water flows from the contact chamber through a 52m3 by- pass chamber then to twoseparate reservoirs. A Miltonic level control system in the by-pass chamber monitors the liquid levels and controlsthe well pumps. The disinfection system and iron sequestering systems both include duty and stand- by chemicalfeed pumps and storage tanks located in a chemical room with secondary containment.

A series of three( 3) vertical turbine pumps direct water from the water plant storage reservoirs to the 1, 650m3elevated water tank based on the liquid level condition within the elevated water storage tank.
