Getting a water supply for a new development (Water main requisition)
If there is no public water main on your development site or outside of your property, you may want to apply for a new water main, commonly referred to as requisitioning. We can design and construct the new water main for you through the requisition process.
To be eligible to apply for a water requisition, you must be building two or more properties that have not previously benefited from a water supply from South West Water.
You can also employ your own contractor to self lay water mains and services, please click here for details.

Isles of Scilly
Isles of Scilly
From 1 April 2020 South West Water became the appointed water and wastewater company for the Isles of Scilly. This means that South West Water took responsibility for existing water and wastewater infrastructure on the islands.
Investing in our region
We believe it is right to support the necessary improvements in water and wastewater services on the islands so that services are in line with standards on mainland UK by 2025 or 2030 in the case of Tresco. This includes the ability to provide new water and sewer connections to the network.
Our wastewater investment will be focused on achieving a reliable wastewater service including being able to cope with extreme conditions, protecting the environment and providing long term benefits to the community.
The balanced investment for each island for water asset improvements will focus on achieving a clean, safe and reliable supply of drinking water.
South West Water appreciate that the island economy is heavily dependent on tourism with over 90% of the islands' income coming from this source. Therefore, our proposed programme of investment will be designed to support and enhance the economy of the islands by improving services and the environment. Once finalised, we will actively communicate with local communities to ensure we work together to deliver improvements in the best way for the communities we serve. Once the asset improvements are delivered to your community we will happily help with applications for new or replacement supplies.
