Guernsey Water Annual Report 2016

Guernsey Water 2016 Annual Report PROTECT OUR ENVIRONMENT water.gg/ annualreport2016 15 Belle Greve Outfalls Replacement (phase 4) Commissioning of our new outfalls was completed in 2015. However the contractual maintenance period did not expire until October 2016 following a successful period of performance. A dive survey in July and August showed the outfalls were performing as expected and no major issues were found. New pumps were installed in the storm pumping station at Belle Greve Wastewater Centre that now meet design standards and permit requirements for discharging flow in storm conditions. Fort George Water quality modelling in 2016 has confirmed the environmental requirements for our improvement of this discharge. We are working with our regulator and estate management company to progress delivery of a cost effective solution in 2017. Business Performance Bathing Water Compliance Sampling showed deterioration in bathing water quality in 2016. We are working with the States’ bathing water quality partnership to improve water quality management in the catchment of streams that pose a risk to bathing water quality. This is of particular relevance to Guernsey Water customers in catchments such as Petit Bot where we also collect water for the supply of drinking water.
