Guernsey Water Annual Report 2016

Guernsey Water 2016 Annual Report SAFE AND GOOD TO DRINK 10 water.gg/ annualreport2016 SAFE AND GOOD TO DRINK Invest in efficient water treatment to improve drinking water and reduce costs Reduce water quality-related customer complaints Our customers trust that our drinking water looks good and tastes good 2 Performance Highlights Our priority was to review the Drinking Water Safety Plans that help us manage water quality risk at every step of our process between source and tap. As a result we have expanded our catchment management (see Protect Our Environment) activity to focus more on addressing water quality risks from agriculture. This work will continue into 2017 and beyond as we improve and refine our plans. Drinking water is vital for public health so it is very important that we have a good compliance record in water quality. We continue to apply best practice in line with UK and European legislation and, in 2016, our compliance improved to 99.91% from 99.84% in 2015. We have robust sampling programmes in place both for compliance and monitoring the raw water we collect and store for drinking water. We will continue to strive for continuous improvement in the quality and taste of our drinking water in 2017 and beyond. That’s why next year we are planning to invite the Drinking Water Quality Regulator for Scotland to externally audit our drinking water compliance monitoring. Capital Investment We have carried out initial refurbishment works at Juas water CASE STUDY Making sure our water tastes good Last year our customers reported they didn’t like the seasonal taste issues with the drinking water. We’ve invested in a meter to monitor algae in our reservoirs; we also set up a panel to monitor the taste of our water supply allowing us to switch to different water sources if algae start to cause problems. 99.91% COMPLIANCE WITH DRINKING WATER STANDARDS
