Describe your Drinking-Water System
Class 1 Water Distribution

The Huron Woods drinking-water system in the Town of South Bruce Peninsula consists of four
wells:
- Well No. W1 and old disused Pumphouse
- Well No. W2
- Well No. W3
- Well No. W6 and existing Pumphouse

The Well No. W1 is rated at 1.21 L/s at a TDH of 83.3 m. The Well No. W2 is rated at 0.6 L/s at a
TDH of 74.2 m.. The Well No. W3 is rated at 1.51 L/s at a TDH of 105 m and the Well No. W6 is
rates at 5.3 L/s at a TDH of 47.6 m.

The existing Pumphouse consists of a Ferrosand Filter system, cartridge filter system, ultraviolet
(UV) disinfection system, chlorination system, filter backwash tank, jockey pump, flow control
valves (hydraulic), and water meters.

The Ferrosand Filter system consists of two Ferrosand Filter units (one duty, one standby) connected
to the common well discharge header, complete with PLC to control backwash cycles,
hydropneumatic tank to drive hydropneumatic valves, and all necessary piping and appurtenances. An
iron-oxidizing sodium hypochlorite feed system with injection point located prior to the Ferrosand
Filter units, consisting of two feed pumps (one duty, one standby) with auto switchover. There are
two submersible well pumps (one duty, one standby) each rated at 20.3 L/s at a TDH of 19.5 m for
the purpose of backwashing Ferrosand Filter units.

The Cartridge Filter system located after the Ferrosand Filter units has a treatment capacity of
9.55 L/s, equipped with a 5-micron size cartridge.

The UV disinfection system has two UV disinfection reactors (one duty, one standby) located after
the cartridge filter unit, capable of providing a minimum dose of 40 mJ/cm2 at end of lamp life and
each rated at 9.55 L/s. Each UV reactor has an automatic cleaning system and an on-line UV intensity
monitor with alarm.

The Chlorination System has a secondary-chlorination sodium hypochlorite disinfection system with
injection point located prior to the treated water entering the reservoir cells, consisting of two
metering pumps (one duty, one standby) with auto switchover. There is also a post-chlorination
sodium hypochlorite disinfection system with injection point located at the high lift header. It consists
of two metering pumps (one duty, one standby) complete with all associated piping and alarms.

The Filter Backwash Tank is one in-ground cast-in-place concrete tank to clarify filter backwash
waste with clarified supernatant discharged by gravity to an existing ditch.

The jockey pump is a submersible well pump rated at 5.67 L/s at a TDH of 56 m within Reservoir
Cell No. 2.

One of the hydraulic flow control valves is located on the inlet piping from Well No. W1 and Well
No. W2 set at 1.21 L/s. Another flow control valve is located in the inlet piping from Well No. W3

O.Reg 170 SECTION 11 ANNUAL REPORT

set at 1.51 L/s. One flow control valve is located on the inlet piping from Well No. W6 set at 5.3 L/s.
The last flow control valve is located on the combined piping from the two backwash pumps set at
20.3 L/s.

There are three water meters:
- One raw water meter for the raw water header
- One total raw water meter located after the common header from all four production wells
- One treated water meter prior to treated water exiting the pumphouse

The 80 kW diesel generator is set with a double-walled sub-base fuel tank with level gauge, low level
float switch and leak sensor, all to be housed in the diesel generator building.

The Huron Woods system also contains one programmable logic controller (PLC) and associated
SCADA system for control of plant operations.
