Groundwater resources offset peak and emergency water demands

Due to the urgent need for an additional water supply source, the Environmental Assessment Office allowed the city to develop a groundwater well.

Based on the report, they would need four groundwater wells, each producing 75 L/s, to produce the required capacity of 25 MLD (300 L/s).

The Environmental Assessment Office allowed the City to undertake the development of one groundwater well with an operational capacity not exceeding 75 L/s. This would operate while the environmental assessment process was underway and prior to the development of the three remaining wells.

We ran a hydraulic model which determined that each well pump would need to produce 82 L/s at 90m total dynamic head. Each well required a 125 HP pump.

The project included:

  • Back-up power
  • On-site sodium hypochlorite generation
  • Chloramination using aqua-ammonia
  • PLC control with SCADA communications
