Jersey's water treatment plant

The Island of Jersey with a population of 87,500 relies on one main waste treatment plant in the town of St Helier, the Bellozanne Depot. For a small island with limited space and high dependence on one site, the Estates of Jersey Public Services Department needed to be sure of a totally reliable and effective pumping solution. They turned to Watson-Marlow Bredel.

Over the years, Public Service Stores, part of the Jersey Government, have grown to trust a high level of service, quality and performance from Watson-Marlow Bredel’s peristaltic pumps and hoses.

The Bellozanne Depot uses Watson-Marlow Bredel SP100 high flow, high pressure hose pumps for primary sludge transfer and digester feed. Matthew McNulty, Purchasing Office for Public Service Stores comments: “With increasingly stringent levels of discharge consent and the need to constantly reduce operating costs, these critical processes must be carried out reliably. That is why we have continued to use Watson-Marlow Bredel pumps over the last 20 years. They provide consistent and accurate performance and are self-priming and dry-running.”

The six SP100s at Bellozanne Depot feed sewerage from settlement tanks into digesters, where all the methane gas is burnt off. The sludge is then moved to a drying plant where the moisture is removed and the remainder made into pellets. The finer effluent is pumped to an ultra violet plant for treatment and then disposal into the sea.
