New mains provided by us
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,

If you require a new or replacement water connection to a new or existing main,
