High-Performance Pumping Solutions for Extreme Weather Events- QLD

Quarry pit dewatering is essential for maintaining safe, accessible, and productive operations. When rainwater or groundwater accumulates in an active pit, it can cause flooding, restrict equipment access, and delay production. Effective dewatering ensures sites can continue operating after heavy rainfall and helps prevent hazards caused by rising water levels. Following a period of intense…

NPE Bypass Solutions for Black Rock Water Reclamation Plant

National Pump & Energy (NPE) was engaged by AMH Civil to deliver a full bypass solution for the Black Rock Water Reclamation Plant (BRWP), enabling major upgrades to the facility’s inlet infrastructure. The project was carried out in partnership with Barwon Asset Solutions who provide maintenance services to the Barwon Water owned site. To maintain…

Wet Season Management in North-West Queensland Mining

NPE supported a remote north‑west Queensland site after heavy rainfall, with 370 mm recorded in seven days. The rain temporarily restricted access, but the team managed the impacts well. They used every available window for treated water releases and kept the site’s water balance steady compared to the previous period. The team also used mechanical…

Stormwater discharge point with flow meter installed for compliance monitoring.

Royal Far West Manly Dewatering

NPE was awarded a dewatering and water treatment project to facilitate construction activities. To manage this project effectively, the temporary groundwater level beneath the basement has been set to 1.0 m below the proposed bulk excavation level, resulting in a level of 3.0 m during the excavation and dewatering processes. Maintaining this lowered groundwater level…

PFAS Treatment Perth, WA

The treatment process begins with a dewatering system that extracts groundwater for processing. The influent is conveyed through the plant, where it undergoes a series of steps to reduce soluble metals and trace levels of Per- and Polyfluoroalkyl Substances (PFAS). Water first passes through the Chemical Dosing Unit, where selected chemicals and coagulants are added…
