Water Quality
The water we supply is abstracted from two surface water sources and 22 regulatory groundwater sources comprising of 62 boreholes, before being treated and distributed to customers via 5880 kilometres of mains and 31 service reservoirs.
On average of all the water supplied, 40% can be taken from underground sources and 60% can be supplied by our surface treatment works. The main treatment works is at Hampton Loade on the River Severn with a maximum output of 215 megalitres per day. The other treatment works is at Seedy Mill near Lichfield which receives water from a large reservoir at Blithfield and has a maximum output of 120 megalitres per day.
The Company’s area is divided into 23 water quality supply zones. Each of these zones is supplied either by a single source or a group of sources that are blended within service reservoirs. The water quality supply zones enable the Company to accurately monitor the quality of the water.
To monitor the water supply, samples are collected and analysed from all stages of distribution including treatment works, service reservoirs and randomly selected customer taps.
During 2005 the Company analysed over 36,000 samples with a pass rate of 99.99%. The tests that were undertaken fall broadly into three categories:
- Bacteriological including coliform organisms and Cryptosporidia
- Physio-chemical such as pH, nitrate, iron, lead and PAH (polyaromatic hydrocarbons).
- Aesthetics such as taste, odour and colour.
The few samples that did not meet with the Regulatory standards did not pose any risk to public health.
