In 2024/25, we invested £2.2 billion, and we will continue to spend wisely on improving resilience, service, and efficiency, as well as provide more support for customers in vulnerable circumstances. We also have additional responsibilities to society and the natural environment. What we do and how we do it delivers significant public value, which is why we have ambitious plans to self-generate more of our own power, reduce our carbon emissions and increase biodiversity across our sites.

United Utilities provides water and wastewater services to around seven million people in the North West of England supplying 3million households and 200,000 business premises. We manage the catchment land around our reservoirs to safeguard the quality of the raw water we collect and store. We then treat and deliver it to our customer's taps - around 1,500 million litres a day We also collect wastewater from our customers and surface water from roads and highways, treat it at our wastewater treatment works before returning it back safely to the environment. In order to do this we have: - 184 reservoirs - over 42,000 km of water pipes, from Cumbria to Cheshire - over 72,000 km of sewers - over 1,400 km of aqueducts - 100 water treatment works - 575 wastewater treatment works - 57,000 hectares of catchment land

We are one of the largest water and wastewater companies in the South East of England and thrive on the passion and hard work of more than 2,000 employees. Together we supply 532 million litres of drinking water every day to more than two million customers and treat and recycle 717 million litres of wastewater for more than four million customers in Kent, Sussex, Hampshire and the Isle of Wight. Water is essential to every aspect of our lives and we're proud to be at the heart of managing water and wastewater services. We drink it, cook with it and use it to clean. Our water supply faces big challenges - the population of the South East is growing fast, and climate change is bringing greater risk of droughts and more extreme weather. It’s a future of more people needing water and wastewater services, with less water to go around. So, together with our customers and communities, we aim to provide a sustainable, high-quality water and wastewater service that helps us create a resilient future for water in the South East.
