Water Connection

The Water Industry Registration Scheme (WIRS), run by Lloyds Register on behalf of water utility companies, has granted AIS Utilities accreditation. According to a standard that is acceptable for adoption by the existing water utility company, the scheme certifies AIS Utilities to design, instal, test, and commission new water networks and service connections.

We collaborate with our clients throughout the course of a project, from the first determination of the network capacity’s accessibility to the delivery of the built-in assets to the water business for full adoption.


The Water Industry Registration Scheme (WIRS) is for contractors that connect new water supply or sewerage systems to existing systems. These are known as “self-lay” organisations, or SLOs.

Designing and Constructing Water Connection Networks

We comprehensively design and cost the water infrastructure in accordance with customer specifications as part of our water design process, either as a stand-alone work or as a component of a complete multi-utility solution.

Excavation, backfilling, and reinstatement are all parts of the process by which AIS UtilitiesĀ instals the entire network infrastructure of water mains and services.

Following installation, our staff carry out pressure testing, disinfection, and final connection to the live water network as part of the commissioning phase before handing over the new water assets to the local water authority.

Timescale for Water Connection Quote

Water connections take up to 10 working days for budget

It can take up to 35 working days for a firm quote
