A reliable, compliant water supply is the lifeblood of any new housing scheme. Our civil engineering team delivers water main installations that meet Uisce Éireann’s standards from the very first connection enquiry through to vesting and handover, giving developers a smooth route from planning to occupation.
Every successful water main installation starts with early engagement. We prepare and submit the Pre-Connection Enquiry to Uisce Éireann, providing the site layout, projected demand calculations, and proposed connection points. Uisce Éireann’s Confirmation of Feasibility then shapes our detailed design and helps developers plan budgets and timelines with confidence. We follow up with the Connection Agreement and manage all correspondence on your behalf.
Our network designs are fully compliant with the Uisce Éireann Code of Practice for Water Infrastructure and the Standard Details and Specifications. This covers pipe sizing for domestic demand and fire flow, hydraulic modelling, valve and hydrant locations, thrust block design, and appropriate cover depths. We specify approved materials such as MDPE and ductile iron, sourced from the Uisce Éireann Approved Products List, ensuring the network is built to last and acceptable for taking in charge.
On site, our engineers oversee trenching, bedding, jointing, and backfill in accordance with best practice. We coordinate carefully with foul drainage, surface water, ESB ducting, gas, and telecoms to maintain the minimum separations required and to avoid expensive clashes. Pressure testing, swabbing, and chlorination are carried out under controlled conditions, with bacteriological sampling arranged through accredited laboratories to satisfy Uisce Éireann’s commissioning requirements.
Each dwelling is connected via an approved boundary box and meter arrangement in line with Uisce Éireann’s domestic connection details. We program these connections to suit the build sequence, keeping the main contractor’s programme on track and ensuring homeowners enjoy a clean, fully tested supply on the day they move in.
Once installation is complete, we compile the full as-built drawings, test certificates, CCTV records, and material certifications needed for Uisce Éireann vesting. Getting this documentation right first time accelerates handover, releases bonds sooner, and gives residents the long-term assurance of a properly adopted public water network.
