What we do in Water and Sewage

Our mission is to provide safe, reliable water to our community and to responsibly manage wastewater to protect public health and the environment.

Working in water and sewage means being part of a team that ensures clean water reaches homes and businesses — and that used water is treated responsibly. It’s a mix of technical work, problem-solving, and community service, with every day bringing something new.

Griffith Water Treatment Plant (GWTP)

The Griffith Water Treatment Plant is a vital part of the region’s water supply system, ensuring safe and clean drinking water for the community. Commissioned in 1987, the plant has the capacity to produce up to 60 million litres (ML) of drinking water per day. Raw water is sourced from Murrumbidgee Irrigation’s main canal at the "Three Ways Bridge." It is stored in the Hayes Lease Reservoir (300 ML capacity) before being pumped to the treatment plant.

Griffith Water Reclamation Plant (GWRP)

On the wastewater side, Council manages three sewerage networks at Griffith, Yenda and Bilbul.

The Griffith Water Reclamation Plant is a state-of-the-art wastewater treatment facility located west of Griffith, NSW. It serves the Griffith sewerage network, which includes approximately 7,500 property connections and 33 pump stations. Sewage collected from Griffith and surrounding villages (Hanwood, Lake Wyangan, Nericon, Tharbogang, and Yoogali) is transported to the GWRP for treatment.

A Day in the Life: Water & Sewage Operations

Working in water and sewage is a rewarding mix of technical expertise, teamwork, and community service. No two days are the same, but here’s a glimpse into what a typical day might look like:

  • Morning checks: Operators start early, reviewing SCADA data and inspecting key infrastructure like pumps, reservoirs, and treatment units. Ensuring water quality and system integrity is the first priority.

  • Water treatment tasks: At the Griffith Water Treatment Plant, staff monitor Dissolved air floatation, filtration, chemical dosing, and disinfection processes. Adjustments are made based on flow rates, turbidity, and chlorine residuals to meet drinking water standards.

  • Sewerage network monitoring: Teams inspect pump stations, respond to alarms, and perform routine maintenance. Wastewater treatment involves biological and chemical processes to ensure safe discharge or reuse.

  • Field work: Staff may collect water samples, repair valves, flush mains, or respond to customer concerns. Safety and environmental protection are always front of mind.

  • Team collaboration: Whether it’s troubleshooting a system fault or planning upgrades, collaboration between operators, engineers, and supervisors is key.

  • End-of-Day reporting: Data is logged, reports are updated, and handovers are prepared for the next day. Continuous improvement and compliance with regulations guide everything we do.

Traditionally seen as labour-intensive, water and sewage operations are rapidly evolving into highly technical fields. Today’s operators and technicians need strong digital skills, an understanding of process control and the ability to interpret real-time data. Careers in water and wastewater are increasingly focused on technology, problem-solving, and continuous learning — making them ideal for those who enjoy hands-on work with a technical edge
