Water supply


Since 1 January 2014, responsibility for the efficient supply of water to homes and businesses has transferred from local authorities to Irish Water. Funding for maintaining and improving the water supply infrastructure (pipes, filtration and disinfection systems) comes from the Department of Housing, Planning and Local Government. The sector is regulated by the Commission for Regulation of Utilities (CRU).

Irish water is currently implementing a 7-year business plan entitled Transforming Water Services in Ireland to 2021 (pdf). The plan has been brought into effect under the Water Services Act 2013 and the Water Services (No. 2) Act 2013. Further information is available on water.ie, and from the Department of Housing, Planning and Local Government.

Ensuring water quality

For further information on how the quality of both public and private water supplies is ensured, see our document on water quality.

Types of water supply

Public water schemes

Public water mains are administered and maintained by Irish Water, however local authorities provide certain services on behalf of Irish Water through service level agreements.

At present, charges are only levied on water supplied to commercial premises. The Department of Housing, Planning and Local Government funds the provision and upgrading of capital projects in water and wastewater services. Irish Water administer the actual building of public water supply projects. Stringent water testing is carried out on all public waters by local authorities and the results are provided to the Environmental Protection Agency (EPA) each year.

Group water schemes

Many households that are not connected to a public water supply are served by group water schemes. These schemes are formed by two or more households coming together to provide their own common water supply. The group elects trustees to act on behalf of its members in all dealings with the local authority.

Usually, group schemes are established in areas where the local authority does not intend to install a water supply system in the near future, or at all. Group water schemes can get water supplies from the public mains, if possible, or from private sources like wells or lakes.

You have to pay for your water if you belong to a private group water scheme. However, local authorities do provide subsidies for each house in a group scheme – see Rates below. Local authorities have the remit to test the water supply and ensure it is safe to drink but they are not responsible for maintaining group scheme pipes and filtration systems.

If the members of a group water scheme want the local authority to take over the running of the scheme, they must sign a waiver to allow local authority personnel on their land to maintain pipes, etc. The group must give the local authority a map of the pipe system and give it access to test pipes for leakage. If the local authority takes over the scheme, it is then responsible for maintaining the water system. However, if a group water scheme remains fully private, it may get technical and grant assistance from the local authority for any necessary upgrading works.

The National Federation of Group Water Schemes is a co-operative society, established to represent the interests of members of group water schemes. It also provides advisory, training, developmental and other services to scheme members.

Private water supplies (groundwater)

If you are not part of a water supply scheme (public or group), you will have to consider boring your own well and drawing out groundwater to supply your needs. The Institute of Geologists of Ireland (IGI) has prepared guidelines for drilling private wells.

When the well is drilled, you should seal it against pollution, make sure it is disinfected and get a sample tested. See the IGI’s guidelines on Water well construction (pdf) for further details. If your water supply has been polluted by negligence, you should contact your local authority. It can prosecute those responsible under the Local Government (Water Pollution Act) 1977.

Water conservation

The Water Services Act 2007 provides for the conservation of water where leakage occurs due to unrepaired pipes or equipment, or where poor management results in wastage or excessive consumption of water. Irish water are currently operating a Leakage Reduction Programme to improve the pipe network across the country.

Regulations made under the Water Services Act (pdf) also apply to water restrictions in times of water shortages. Irish Water can make an order to stop or restrict the use of water supplies for:

  • Watering gardens, recreational parks or sports grounds
  • Washing cars and trailers (including by commercial car wash facilities)
  • Filling or replenishing swimming pools, ponds and lakes
  • Irrigating or spraying crops.

It is an offence not to comply with a water conservation order.


Individual Supply Grant Scheme

Under this scheme, if your house is more than 7 years old and not connected to either a public or a group scheme, you may be eligible for a grant (subject to some conditions). The grant is worth up to €2,031.58 (or 75% of the cost of the work, whichever is the lesser) and must be used to provide a new water supply or to upgrade an existing one. Only one grant per house will be allowed in any 10-year period. In order to qualify for the grant, the proposed work must cost more than €635. A local authority inspection will be carried out before any work starts.

The kind of work that would be eligible for the grant is the drilling of a new well or the provision of essential pumping or water filtration/disinfection equipment.

For more details and application forms, apply to your local authority.

Group Water Grant Scheme

Grants are available from the local authority if 2 or more householders get together to provide their homes and farms with a water system where none exists. A committee that represents the scheme members must propose the scheme and the local authority must approve it. The amount of grant payable depends on where the scheme is located. Check with your local authority for details of your area. Generally, a grant will cover 85% of the cost, with a limit of €7,650 for each house in the scheme. The group members must cover the balance, but costs can be kept down if members can do some of the work themselves.

An annual subsidy is available for the running costs of the group water scheme. This must be approved by the local authority. The amount of subsidy is 100% of the qualifying expenditure up to the following limits:

  • €70 for each house supplied from a from a local authority source (public mains)
  • €140 for each house supplied from a private source (such as a private well)
  • €220 for each house where a group scheme has provided its own water treatment plant under a Design, Build, Operate (DBO) contract

How to apply

You can find grant forms and water supply information on your local authority website. Further information about water supply is available from Irish Water.
