Self lay

We support developers that wish to construct their own mains. This is commonly referred to as ′Self Lay′.

Self Lay is the process where, the developer instructs a third party to install new water mains.

Before commencing a Self Lay mains scheme, we recommend that both the developrs and the Self Lay Organisations (SLO) familiarise themselves with the current nationally agreed ′Self Lay Code of Practice′ and our company specific addendum to the code of practice.
