Code for Adoption Agreements

To arrange water supplies for your site or new property, you can choose the installer that best suits your needs and timescales. This might not be Portsmouth Water. It may be more economical and may suit your building programme for an independent ‘self-lay provider’ (SLP) to install the water mains. In addition it may afford you opportunities to use one SLP to install multiple utilities.

The SLPs are accredited to the standards necessary for us to adopt the pipework at completion. We supervise their work in the same way that we supervise our own contractors.
