Hall Water Treatment Works, which is aimed at supporting city growth and combating future droughts across the county, was officially opened yesterday.
Close to Newton-on-Trent, the facility will take water from the River Trent allowing previously untreatable water to be purified.
River water will then be pumped into a newly constructed 20 acre reservoir, which holds 300 million litres of water, and up to 20 million litres every day will be treated before it is supplied to homes and businesses in south Lincolnshire.
Anglian hopes the new reservoir can help mitigate the effects of increasing climate change, droughts and population.
The water company covers the largest geographical area of any in England and Wales and the region has been classified by the Environment Agency as under “serious water stress”.
Peter Simpson, chief executive of Anglian Water, said: “Between now and the end of the decade, Lincolnshire is expected to continue to grow at a faster rate than the national average. For this county to continue to grow, and for its businesses to continue to prosper, it’s vital that services like water are readily available to the communities and businesses which rely on them.”
In total Anglian has plans to invest £327 million in the county’s water and water recycling infrastructure between 2010 and 2015.
