Sourcing Your Water Supply

The three main sources of water supply are as follows:

1) Installation of a Private Well.

2) Connection to the Local Authority Water Supply.

3) Connection to a Group Scheme.

1. Private Well

If you do not have access to a Local Authority or Group Water Scheme you can drill your own well. This method often provides better quality water and is not subject to cut offs by the Local Authority or Group Scheme due to shortages, repairs etc. If you intend to source your water supply by this method the following considerations have to be taken into account:-

  • Positioning the Well in relation to contaminating sources. Regulations require a distance of between 15m to 60m. This distance is dependant on the type of soil/subsoil, the depth of soil/subsoil above bedrock, the T/P-value, whether the location of the well is down gradient, level or up gradient from the wastewater treatment system. It is advisable to position the well up gradient of the wastewater treatment system where ever possible.

  • Construction of the well.

  • Testing the sustainable yield of the well.

  • Testing the water quality.

To cover the cost of providing a bored well together with all pumps, pressure vessels and associated plumbing and builders work you need to budget in the region of €4,500.00 - €6,750.00. However some installations may cost more due to the nature of the substrata and the required depth of the well.

          Appointing a Well Drilling Contractor


Contact a number of Well Drilling Contractors in your area to ensure they would be interested in quoting you for the work. (You can find these by referring to the Suppliers and Services part of this Web Site)

If they are in a position to quote for the work you should forward them the drawings and specifications together with a cover letter outlining the work you wish them to quote for, which should include quotation return dates and project commencement and completion dates.


You should endeavor to obtain three to four quotations.


On receipt of the quotations, checks should be carried out to:


Ensure that they are fully covered by Employers Liability, Public Liability and All Risks Insurance and that you are completely indemnified against any claims. You should have your Insurance Broker check that these insurance policies are suitable for your requirements and that they are in order.


Ensure that they have included for all work as outlined in your tender enquiry.


Ensure that there are no arithmetical errors in their quotations.


Ensure that you are comparing like with like.


Ensure that the lowest quotation is not so low as to cause concern that the quality of the work may be compromised


          Things to look out for:

Ensure there is adequate access for the drilling rig. It is advisable that the drilling contractor visits the site during the tender process and acquaints himself with the access, terrain and the drilling location.


Obtain a commencement and completion date for the works.

Ensure the Drilling Contractor has included for all testing and disinfecting on completion.

Ensure the Drilling Contractor has included for all pumps, pressure vessels etc.

Ensure you get a copy of the test results and that they are forwarded to the relevant authorities.

2. Local Authority Water Supply

If the Local Authority water mains passes by your site and you have unobstructed access to it, you can apply to the Water Services Department of the Local Authority for connection to same. Some Local Authorities insist on carrying out all of the connection work themselves whilst others expect the applicant to carry out the work under the supervision of the Water Services Engineer. Requirements will differ depending on the Local Authority but they will all require the following information:-


  • Applicants Name

  • Applicants Address

  • Contact Telephone Number

  • Address for Billing Purposes

  • Location of Connection

  • Planning Reference Number (where applicable)

  • Development Charges Receipt Number (where applicable)

  • Site Location and Site Layout Map indicating the location of the property to be served, the location of the proposed connection and the route the pipe is to take.

  • On receipt of the above you will be notified of the appropriate fees, which you must discharge before a licence is issued and work can begin.

  • Connection fees differ between Local Authorities but you should budget in the region of €1,000.00 to €3,000.00 for both the fees and cost of the works.


3. Group Water Scheme
A Group Water Scheme is a private scheme, which is formed by a number of householders in a given area. The source of the water may be from either a private well or reservoir etc. or from a Local Authority Mains. Group Water Schemes, if properly organised, can benefit from subsidies from the Local Authority towards operational costs. The amount of subsidy varies between the Local Authorities and you should check the amount of subsidy applying to your area. Group Water Schemes should be properly maintained and a water supply testing programme should be in place. Application for connection should be made to the scheme officers, who will inform you of the connection charges. In addition you may also have to apply to the Local Authority for road opening licences and pay the appropriate fees. Connection fees differ between Group Schemes and road opening licence fees differ between Local Authorities but you should again budget in the region of €1,000.00 to €3,000.00 for both the connection fees, road opening licence fees and cost of the works.
