If a development requires a new water main or sewer, the developer may ask the water or sewerage company to install the pipework. When this is required for domestic purposes (cooking, cleaning or sanitary facilities), it is known as requisitioning.
Alternatively, they may choose their own contractor to do the work, which is known as self-lay. The water company will take over responsibility for (adopt) self-laid pipes that meet the terms of its agreement with the developer or self-lay organisation (SLO) that carries out the work.
