Water recycling treatment plant of tomorrow : John Holland SUEZ Beca joint venture wins contract to upgrade the Boneo water recycling treatment plant in Australia

South East Water, the authority in charge of water, sewage and recycled water services in south east Melbourne Victoria, has awarded SUEZ and its joint venture partners John Holland and Beca, the contract to upgrade the Boneo Water Recycling Treatment Plant located on the Mornington Peninsula. The upgraded plant with innovative technologies will produce renewable resources (water and energy) that will significantly contribute to the region’s growth and environmental significance.

The contract includes the design and construction of the plant upgrade for a total investment of approximately €80 million, and its operation for a period of 10 years.

The construction phase will start in February 2019 and increase the Plant’s capacity to 31,200 m3 wastewater per day from the existing 14,300 m3 per day. The contract will optimize the sewerage treatment service for the Mornington Peninsula community, supporting the current and future population growth. In addition, the upgrade will secure recycled water production that will be used by local farmers for irrigation.

The joint venture will modernize the plant by delivering a range of innovative treatment technologies designed to reduce South East Water’s reliance on grid electricity, taking the utility one step closer to achieving its emissions reductions target of 45 per cent by 2025.

SUEZ will deploy a breakthrough technology in wastewater treatment (CleargreenTM Mainstream). This technology reduces oxygen consumption by 50% compared to conventional treatment and increases biogas production, which will be used to produce electricity to supply the plant. This process and other technologies deployed will have the potential for the plant to become carbon positive.

«The Boneo Water Recycling Plant upgrade will support the continued growth of the Mornington Peninsula. It will also move us significantly closer to our emissions reduction targets, and our commitment to customers to protect our environment.» said Terri Benson, Managing Director at South East Water.

With this new contract, SUEZ helps to provide 3.5 million Australians with wastewater treatment services. The Group provides water and wastewater services in major metropolitan areas such as Perth, Adelaide, Melbourne and Sydney.
