Background
A large mining company operating in a remote location with no existing sewage or wastewater infrastructure needed a fit for purpose treatment system. Due to the remoteness of the site and the challenges posed by seasonal heavy rainfall, constructing an in-situ plant was not feasible. Additionally, access roads in and out of the site are subject to flooding, so the plant required a robust, reliable design that minimised waste streams for off-site disposal.
Solution
MAK Water prepared a concept design during the tender phase that addressed the remote location and challenging operating conditions. Through value engineering and adherence to client specifications, a customised plant was delivered to meet the client’s budget. The final solution incorporated lessons learnt from previous projects to optimise the design and implementation.
MAK Water Key Solutions
- Modular package plant built off-site under controlled conditions
- Interconnecting pipe spools prepared to minimise on-site installation time
- Sludge dewatering system to eliminate the need for a clarifier and reduce sewage treatment sludge requiring off-site carting.
- Septage Removal System for accepting and screening of tankered septage and raw sewage
- New package sewage pump stations
- 315 Kl/day Membrane Bio Reactor (MBR) to achieve class A treated effluent
- Coal mine compliant electrical control panel with REPQ verification
- Client specific vendor data requirements (VDRL)
- Externally bunded IBC enclosures for ease of chemical handling
- Installation and commissioning of new plant
