Describe your Drinking-Water System
Class 2 Distribution, Class 3 Treatment
Raw water intake (450mm polyethylene, extending 200m into Colpoy Bay) enters plant through a mechanical
traveling screen. There is also a back-up 450mm intake parallel to the main intake that extends 60m into Colpoy
Bay. Zebra mussel control is installed at the intake crib and utilizes sodium hypochlorite on both intake lines.
Pre-chlorination is also available at the raw water well inlet. The two compartment raw water well has two
vertical turbine low lift pumps (31.3 L/s) installed in each compartment. Raw water is pumped to flocculation
tanks and polyaluminum chloride is injected into the raw water feed line at a flash mixer prior to entering the
two floc tanks.

Powdered activated carbon can also be injected in this line upstream of the mixer. Sodium hypochlorite can also
be injected prior to the mixer if required. Water flows from the floc tanks to the two dual media filters. The
filtered water then passes into a dual-compartment clear well/contact chamber/ backwash storage reservoir
(capacity of approx. 809m3). Two high lift pumps (capacity of 60 L/s each @ 77.7m TDH) supply water to the
distribution system from the water treatment plant. The plant has a filter backwash system that utilizes water
stored in the clearwell. Two backwash pumps with a capacity of 167.8 L/s each and four surface agitators
provide filter washing when required. Backwash wastewater is stored in two surge tanks with a total volume of
512 m3. Two waste transfer pumps pump the surge tank contents to a sedimentation tank and with the addition
of a polymer the waste sludge is transferred to an on-site sewage pump station where the plant wastes are
pumped to the sanitary sewage system. Two Ultraviolet (UV) disinfection reactors located on the high lift
discharge header. Each unit is designed to provide a minimum pass through dose of 40mJ/cm2 at a minimum
UVT of 90% at a maximum flow rate of 87.4 L/sec.

Potable water produced by the plant is fed directly to the distribution system with the excess water filling the
2894 m3 water standpipe which supplies pressure to the system and controls the water plant operation by preset
level controls in the tower. A booster pump station located at the water storage tower site supplies additional
pressure to the higher elevations located in the northwest section of Wiarton.
