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
