The environment we care for

Our work for the environment is about halting the decline of nature and leaving places better than we found them.

The mix of different landscapes in the South West makes it a particularly special place to look after. We have amazing partners who work with us to keep it thriving, like the Wildlife Trusts, West Country Rivers Trust, South West Lakes Trust, the Environment Agency, Natural England and many more.

Here’s a glimpse into the places we help manage.

Taking responsibility

Operating water and wastewater networks comes hand-in-hand with working with, and for, the environment. We're working hard to reduce the impact our operations have on the environment, including areas like carbon emissions, biodiversity and water quality. 

Some of our activities that impact the environment are:

water abstraction
Our impact on the environment


This is when we take water out of the environment for treating into drinking water. We're heavily monitored on this by the Environment Agency who outline exactly how much we can take and when. This is particularly tricky during drought conditions when demand remains the same but the amount of available water is low.

Our impact on the environment


Both water and wastewater treatment uses a lot of energy. Many of our works are fitted with solar panels or use bio-fuel generated onsite to help supplement their energy needs.

Pumping stations help water and wastewater travel uphill (and the South West has many hills!). This also takes a huge amount of energy. We’ve done a lot of work to make our pumps as efficient as possible.

Our impact on the environment


When storm tanks overflow, wastewater spills directly into watercourses. This prevents it from backing up into your homes and gardens, but sadly has negative impacts on the health of those watercourses. We’re investing £330 million between now and 2025 to reduce the number of times these spills happen.

Our impact on the environment


When roads, fields or moors need digging up for us to access pipes and valves that need fixing, we make sure to return those areas to how we found them. We’ve also committed in improving biodiversity at those sites.

Our Environmental Projects

We not only want to meet the environmental standards put on our business, but surpass them. We know we have a long way to go, but we’re confident that we will get there, and quickly, so that the places you love are kept safe and beautiful.

Water resources - Latest situation

Our water resources are strictly managed to make sure we always have enough supply to match demand. During the hosepipe ban, we were busy increasing the resilience of our water network to help better secure our water resources for the future.
