Water Main Repair near you

Start at the street. The main is the company's, and so is the communication pipe that connects it to the boundary, along with the external stop tap in the footpath. From that stop tap inwards, the supply pipe and all the plumbing inside the property are the owner's. It is a boundary of ownership rather than a boundary of visibility: a wet patch in the middle of your front garden is on your side of it, and a wet patch in the pavement two metres away is not.

Shared supplies complicate this in British terraces, converted houses and older estates more often than anyone expects. Where one pipe serves several properties, CCW's position is that it becomes the joint responsibility of all the owners connected to it, which means a repair is a negotiation as much as an engineering job. NI Water notes the same arrangement causes low flow and pressure when neighbours draw water at the same time, and says it usually recommends that each property has a separate supply, with a separation of supply application available for that.

Scotland's arrangement is administratively simpler and technically the same: Scottish Water is the single authority, and it says that within the home a burst pipe is the owner's responsibility to fix and should be fixed immediately. It points householders at the WaterSafe register for qualified plumbing and heating professionals, and notes that SNIPEF runs the Plumbing Industry Licensing Scheme which forms part of WaterSafe.

Planned work carries a notice requirement. Under the Water Supply and Sewerage Services (Customer Service Standards) Regulations 2008 as amended in 2017, where an English wholesaler exercises its power under section 60(1) of the Water Industry Act 1991 to disconnect for the carrying out of necessary works and is required to serve notice under section 60(3), regulation 17E requires the notice to specify the earliest date and time after which the supply is reasonably expected to be interrupted and the latest date and time by which it is reasonably expected to be restored. If the water is to be cut off for more than four hours, at least 48 hours' notice must be given before the interruption.

Emergencies are treated differently but not silently. Where the supply is interrupted because of an emergency and the wholesaler is excused from serving notice, or where the supply is interrupted otherwise than by the wholesaler exercising its powers, the regulation requires it to take all reasonable steps, as soon as reasonably practicable, to notify each affected customer.

The structure of these Regulations changed in 2017 and it is worth knowing which Part applies to you. The 2017 amendment retained the existing provisions in Part 2 for water and sewerage undertakers whose areas are wholly or mainly in Wales, and inserted a new Part 3 replicating those standards for English undertakers and for licensees supplying under a retail authorisation, modified to reflect the split between retail providers and wholesalers. So the Welsh standard sits at regulation 8 and the English one at regulation 17E.

There is a statutory floor. Regulation 17G of the 2008 Regulations requires an English water wholesaler to maintain, in a communication pipe serving premises supplied with water, a minimum water pressure of seven metres static head. If the pressure in that communication pipe falls below it for an hour or more, and then does so again before the end of the 28 days beginning with the day of the first failure, the English service provider must pay the customer 50 pounds. The failures do not count where they happen in connection with the carrying out of necessary works or because of drought, and the obligation falls away once payments totalling 250 pounds have been made to that customer in respect of pressure failures.

The Welsh equivalent, regulation 10, sets the same seven metres static head and a payment of 25 pounds on the same two-occasions-in-28-days test, with the same exclusions for necessary works and drought. These amounts are not fixed for ever: regulation 17IF provides for the English amounts to be adjusted where the all items consumer prices index for the September preceding a 1 April payment change date has risen by at least 10 per cent against the index for September 2025, with the result rounded to the nearest 5 pounds.

Note what the standard measures. It is pressure in the communication pipe, not at your kitchen tap. If the company can show seven metres static head at the boundary, poor pressure inside the house points at your own supply pipe, at its diameter, at its length, or at internal pipework, and that is a plumber's job rather than the company's.

A modern supply pipe replacement is usually a run of blue medium density polyethylene from the boundary stop tap to the point of entry, in one continuous length wherever possible, because every buried joint is a future leak. On soft ground the pipe can often be moled or pulled rather than trenched, so the lawn is disturbed at each end and not along the whole route. Under a drive or a paved path the calculation changes quickly, and the reinstatement is frequently the biggest line on the quotation.

Depth is set by two different considerations. Schedule 2 to the Water Supply (Water Fittings) Regulations 1999 requires a fitting laid below ground to have a depth of cover sufficient to prevent the water in it freezing, and requires every fitting to be installed so as to inhibit damage by freezing or any other cause. Separately, the notification Table in regulation 5 makes any water system laid outside a building and either less than 750mm or more than 1350mm below ground level an operation requiring notice to, and the consent of, the water undertaker. In other words, going shallower or deeper than that band is not forbidden, but it is not something to do without telling the company.

Two other things belong in the conversation before the trench is opened. If the existing pipe is shared, this is the moment to ask about separating the supplies, since NI Water and others actively recommend a separate supply where flow and pressure suffer. And if the old pipe is lead, ask the company what it will do about its own side, because the answer varies: NI Water states that where you replace your lead supply pipe it will replace its part of the same pipe free of charge, and notes that a grant may in some circumstances be available from the Northern Ireland Housing Executive towards your share, to be applied for before work starts.

Work that crosses the highway is not something a domestic plumber can simply start. Section 50 of the New Roads and Street Works Act 1991 lets the street authority grant a street works licence permitting a person to place or retain apparatus in the street, and thereafter to inspect, maintain, adjust, repair, alter or renew it, change its position or remove it, and to execute any works required for or incidental to that, including breaking up or opening the street, or any sewer, drain or tunnel under it, or tunnelling or boring under the street. The Act treats reinstatement of the street as among the works the licence covers.

For most householders the practical effect is that the company does the bit in the road and a contractor does the bit in the garden, with the boundary stop tap as the handover point. Where a private contractor is to work in the highway, ask to see the licence or permit arrangement and ask who carries the reinstatement obligation, because a failed reinstatement is expensive and it follows the apparatus rather than the invoice.

A leaking supply pipe is not only your expense; it is potentially your legal problem. Section 75 of the Water Industry Act 1991 applies where a water undertaker has reason to believe, among other things, that damage to persons or property is being or is likely to be caused by damage to or a defect in a water fitting used in connection with the supply which is not a service pipe belonging to the undertaker, or that water supplied to the premises is being or is likely to be wasted or, having regard to the purposes for which it is supplied, misused or unduly consumed.

Where the case constitutes an emergency, the undertaker may disconnect the service pipe or otherwise cut off the supply, and must then serve a notice as soon as reasonably practicable specifying the steps required before it will restore the supply. In any other case it may serve notice on the consumer requiring specified steps to be taken, and that notice must give a period of not less than seven days beginning with the day after service. If the steps are not taken by the end of that period, the undertaker may take them itself and recover the reasonable expenses from the person on whom the notice was served. Section 75(10) provides a protection: if it turns out the steps were not necessary, the undertaker cannot recover its expenses and must reimburse anyone else who incurred them.

Ofwat sits behind all of this as the economic regulator. Section 1A of the Water Industry Act 1991 establishes the Water Services Regulation Authority as a body corporate carrying out the functions conferred on it by that Act, performing its functions on behalf of the Crown; Ofwat is the name it operates under. It is not the body you ring about a burst, but it is the body whose price and performance framework determines how much leakage reduction and mains renewal your company is committed to.
