From the fields that help feed the nation to the coastline enjoyed by locals and holidaymakers, water is at the heart of life in Lincolnshire. Home to more than 480,000 homes and businesses, the county depends on a reliable water network to support farming, communities, and the natural environment.
As demand grows and climate change brings more extreme weather, through drier summers and heavier downpours, pressure on the local network is increasing.
That’s why we’re building for better in Lincolnshire for today, for tomorrow and for generations to come. The work’s already underway - we’re investing £350 million* to secure water supplies for the future, protect the environment and support our local communities.
Building a better network for Lincs
As more people call Lincolnshire their home, we’re investing to make sure we keep taps flowing and toilets flushing now and for future generations. We’re upgrading our sewer network and water recycling centres, to increase capacity and serve more homes and businesses. It’ll also help to keep wastewater flowing where it should and prevent spills, even during heavy downpours and more extreme weather as our climate changes.
In the last year, we’ve already replaced over 40km of water pipes across the county including work in Spalding, and this year we’re replacing nearly 120km more, to drive down leaks and bursts - keeping water flowing to homes and businesses. As well as investing millions of pounds to upgrade water treatment works supplying Lincolnshire with water, building a reliable and resilient water supply for the future. We are also building a new pipeline to move water around the region wherever and whenever we need it, to minimise the impacts of drought and dry weather on our region.
Securing more water for the future
Our region is growing fast, but with less rainfall and more people using water every day, we’re investing millions into securing additional water supplies. As part of this, we’re developing a new reservoir just southeast of Sleaford that’ll supply the county with up 169 million litres of water every day.
It’ll also help us to protect the environment and keep nature thriving, by reducing pressure on sensitive water sources such as chalk streams. With extreme weather becoming more and more common across the region, we’ll be able to store water to use in dry weather - when we need it most. As well as helping us to make sure river levels aren’t getting too high during periods of heavy rainfall, which can lead to flooding.
Not only will it help us a deliver reliable water supply to Lincolnshire - whatever the weather - it’ll also create new jobs and become a relaxing place for the local community to visit and for nature to thrive.
But the work to make sure we’ve got enough water to go around doesn’t stop there. We’re also looking into innovative ways to source more water, such as turning seawater safely into drinking water (which is called desalination). All to keep taps flowing and build a network we can rely on. Today, tomorrow and for generations to come.
Protecting the environment
Having a thriving environment is important to all of us, that’s why we’re investing £69 million to keep Lincolnshire’s rivers and coastlines healthy. We’re upgrading six water recycling centres across the county, including Canwick and Marston.
We're investing in new equipment to improve our processes for removing nutrients like phosphorous—from soaps and cleaning products — that can be harmful to wildlife when it reaches rivers and other watercourses.
We’re also increasing storm tank capacity, helping the network to deal with heavy rainfall and prevent spills, protecting the environment and making sure nature can thrive.
But we can’t do it alone. We work closely with farmers to improve river water quality, by encouraging good farming practices that improve soil quality and, in turn, keeps nutrients, pesticides and soil in the fields. Our grants to support farmers are just one of the ways we do this by funding water quality improvement projects.
Our region is also the home to beautiful beaches, rivers and reservoirs that thousands of people enjoy every year. In Lincolnshire there are 9 designated bathing water spots where people can swim, paddle, walk, unwind and breathe – all rated ‘Good’ or ‘Excellent’ in 2026. They’re special to our communities, which is why looking after them matters so much. We’re investing £25 million to improve bathing water quality across Lincolnshire, protecting rivers and coastlines and making sure they remain the much-loved holiday destinations they are today.
We’re building for better in your area and across the region. For today, tomorrow and for generations to come.
