Pump Failure Causes Wastewater Overflow in Suva; Public Urged to Dispose Waste Responsibly

Wastewater operations have returned to normal in Suva after a significant overflow incident occurred along Cumming Street. The Water Authority of Fiji (WAF) confirmed that its response teams acted swiftly upon receiving reports of the overflow, carrying out immediate repairs, disinfection, and cleaning of the affected areas.

The failure occurred after the pump control float switches became entangled with a large amount of foreign material that had entered the wastewater network.

The root cause of the incident was identified as a pump failure at the Robertson Pump Station, a key facility responsible for receiving and transferring wastewater from the surrounding catchment. Investigations revealed that the pump's control float switches became entangled with a substantial volume of foreign materials that had entered the wastewater network. These materials included plastic bags, rags, wet wipes, and clothing, all items that should not be flushed down the system.

WAF emphasized that while their pump stations are equipped with screening systems to prevent such waste from reaching the pumps, the sheer quantity of improperly disposed items in this instance overwhelmed the capacity of the screens. This excess material disrupted the pump control mechanisms, leading to the temporary system failure and subsequent overflow. The authority reiterated its plea to the public for responsible waste disposal, reminding citizens that the wastewater network is designed solely for human waste and wastewater.

Items such as wet wipes, diapers, sanitary products, rags, clothing, plastics, paper towels, cooking oils and other solid waste should not be flushed or disposed of through the sewer system.

The incident serves as a stark reminder of the consequences of flushing non-flushable items. WAF highlighted that such actions are a primary driver of wastewater blockages, pump failures, manhole overflows, and damage to critical infrastructure. Beyond the immediate disruption, these issues create public health and environmental risks, while also diverting essential resources that could otherwise be used for maintenance, service improvements, and infrastructure development. WAF expressed gratitude for the public's patience during the resolution process.

Improper disposal of these materials remains one of the leading causes of wastewater blockages, pump failures, manhole overflows and damage to critical infrastructure.
