WTE Modernises Gilău Water Plant in Romania

WTE has completed the modernisation of the Gilău drinking water treatment plant, a key facility supplying Cluj-Napoca and surrounding communities in Romania. The upgrades enhance the plant’s capacity and operational efficiency, supporting the delivery of high-quality drinking water across the region. The project reflects a focus on sustainable infrastructure and supply security.

The plant, originally commissioned in 1973 and expanded in subsequent decades, now operates with a capacity of nearly 229,000 cubic metres per day. Water is drawn from three surface reservoirs and passes through multiple treatment stages, including coagulation, microfiltration, sedimentation, and rapid filtration. The installation of a new sludge line enables the reuse of backwash water, while a 300 kW small hydropower plant at the intake provides renewable energy to offset part of the facility’s electricity needs. The system’s design incorporates gravity-based transport, optimising energy efficiency throughout operations.

The project demonstrates the integration of established engineering practices with modern technologies to strengthen water supply resilience. By combining advanced treatment, resource recovery, and energy-efficient measures, the plant aims to meet current and future demand in Cluj and, eventually, neighbouring districts.
