The annual report for 2017 shows a surplus for the year of £3.3 million, a reduction of 1.1 per cent, or £38,000, from 2016.
However, water quality for the same period achieved an overall compliance rate of 99.98 per cent, while nitrate levels in treated water were the lowest for many years.
The maximum levels detected in treated water were 36.6 mg per litre, compared to 40.7 mg per litre in the previous year. The health regulatory limit is 50 mg per litre.
In addition, operating costs in 2017 rose by £412,000 to £11.1 million due to increased expenditure on water quality initiatives, cyber-security and pension charges.
‘We are pleased with our financial performance and with our water quality results for the year,’ said Jersey Water chief executive Helier Smith said. ‘Both are testament to the hard work of everyone in the team at Jersey Water.
‘We are committed to providing the best service and value for our customers and are very proud of the excellent results from the customer satisfaction survey. We will work hard to build on that firm foundation in order to ensure we continue to meet the needs of our customers in the years to come.’
The 2017 report also shows that turnover for the year increased by 1.5 per cent to £15.96 million, yet consumption decreased by 3.2 per cent to 7.3 billion litres. The fall is attributed to a 14 per cent reduction in leaks, coupled with high rainfall over the usually drier summer months.
‘During the year Jersey Water invested £3.3 million in its capital expenditure programme,’ a company spokesman said. ‘This included replacing 2.1 km (1.3 miles) of mains, extending the network by 1.9 kilometres (1.1 miles), connecting 303 homes to mains water, undertaking a number of water quality initiatives and completing the commissioning phase of the desalination plant. Leakage management initiatives resulted in a reduction of 14 per cent for the year.’
