Water Main Renewals

Private water mains — common on farms, estates, holiday parks and older commercial sites — were often laid decades ago in iron or early plastic. When they start failing, patch repairs quickly become false economy.

Renewal replaces the ageing main with modern MDPE or barrier pipe, sized properly for today's demand, usually with directional drilling to minimise disruption to the site.

Water Main Renewals — common questions

Can we keep water on during the works?

Usually yes — the new main is laid and tested alongside the old one, with a short planned changeover at the end.

Who owns a private main?

The landowner(s) it crosses and serves. Unlike public mains, all maintenance falls to you — which is why renewal beats perpetual patching.

Trenchless or open-cut?

Directional drilling costs more per metre but saves surfaces, access and reinstatement — across a working site it's very often the cheaper total.
