General information on your drinking water

The water system served a total of 572 persons. Raw water is supplied to the plant by two wells each containing a single pump.  This raw water undergoes chlorination using Sodium Hypochlorite.  A Manganese sequestrate is also added in order to keep the Manganese soluble.

The treated water is then supplied to the community and the reservoir (located at the other extremity).  At the reservoir there is another chlorination system.  At any given time the community is supplied by the wells or the reservoir.  The sequence is as follows; the service well pump comes on when the level of the reservoir reaches 19 m, during this time the community is supplied by the service well pump and it’s associated treatment (disinfection/sequestrate).  The excess water not consumed by the community goes into filling up the reservoir (Stand pipe).

When the level of the reservoir reaches 23 m, the service well stops and the flow through the network is reversed and the community is now supplied via the reservoir and it’s associated treatment (disinfection) until the level of the reservoir reaches 19 m and the service well kicks in again and flow reverses once again.  This alternation continues with each cycle.  A fire pump located at the reservoir comes on when then the pressure in the network drops below it’s set point.  There are inline continuous analyzers located at the wells site and reservoir.  There is a process control computer (SCADA) located at the community garage that enables the operators to monitor the various systems.

General information on your wastewater system

Wastewater is collected by the sewage network and pumped via 5 lift stations to the treatment site.  The treatment site comprises of three aerated lagoons laid out in series.  Two (2) variable speed blowers feed air into the lagoons through submersible aerators (ATARA).  The treated effluent is then pumped into the storm network of the neighboring town of Maniwaki then eventually reach’s the Gatineau River. It serves 541 persons approximately. After treatment, the treated water is pumped to reach the river.
