Frequently Asked Questions

If a development requires new water mains, the Developer may ask the Water Company to install the pipework, which is known as requisitioning, or alternatively, they may choose a WIRS Accredited contractor to do the work, which is known as Self-Lay.

An Agreement between all parties involved, which includes the Self-Lay Organisation (SLO), the Developer/and or Land Owner and the Local Water Company has to be signed prior to the commencement of works. This document is known as the Self-Lay Agreement (SLA).

A copy of the water company's design and offer letter is enough for us to provide prices for water, but a Self-Lay Agreement will still be required for the site. Our team will ask for any job specific paperwork as and when required.

No problems, we will approach them on your behalf. In truth, it is our preference because if we have involvement in the scheme from the outset we can minimise time delays on liaison with the water companies.

Should it be cost effective for you to do so, we will try to design the Water Network to coincide with other proposed utilities in a common trench. As the Local Water Company will be adopting the network they will have to approve the design and use it to form part of the Section 51a Agreement.

Initially you can contact our Client Managers/Project Managers who will be assigned as your primary point of contact.
