Septic Tank Grants Available in Ireland


The Home Renovation Incentive scheme is no longer available in Ireland since December the 31st, 2018. On the other hand, the DHPLG (Department of Housing, Planning and Local Government) has been maintaining its DWWTS grant. We invite you to visit website to get further information on how to qualify for financial assistance.


 In 2013 the EPA initiated its National Inspection plan, a regime for inspecting domestic wastewater treatment systems (or better known as septic tanks) throughout Ireland, grants to upgrade existing septic tanks was a huge talking point at the time. Outlined below is some useful information that will help answer your questions.

Currently, in Ireland, two septic tank grants are available for the repairs or upgrade of your system.

  • Domestic Waste Water Treatment Systems (DWWTS) Scheme.
  • Home Renovation Incentive (HRI) scheme.

Domestic Waste Water Treatment Systems (DWWTS) Scheme

The responsibility for the provision of funding for the DWWTS scheme grant lies with the Department of Housing, Planning and Local Government (DHPLG). Additionally, under the Rural Water Programme, the local authorities will administer the grant scheme.

This DWWTS grant is available to help homeowners with the cost of repairs, upgrades or replacement of their domestic wastewater treatment system. The grant will only be issued following an inspection from an approved and appointed Environmental Protection Agency inspector and also upon receipt of an Advisory Notice by the local authority.

What are Domestic Waste Water Treatment Systems (DWWTS)?

Domestic Waste Water Treatment Systems (DWWTS) includes septic tanks and wastewater treatment systems.

Requirements to benefit from septic tank grants – DWWTS scheme

The septic tanks grant scheme for domestic wastewater treatment systems is not a universal scheme. Indeed, to benefit from a grant, the following conditions apply:

Non-qualifying work

Costs of maintenance, servicing and de-sludging your wastewater treatment system are outside the scope of the septic tank grants scheme.

Insurance: If an insurance payment is used for works to a property, the total qualifying cost will be reduced by the amount received from an insurance company payment.

Level of Grant – Septic tank grants

As mentioned above, the septic tank grant is mean tested. Indeed, the level of grant is based on the gross household income and is either 50% or 80% of the approved costs of the works.  See the table below.

Household income* % of approved cost of work available Maximum grant
Up to 50,000€ 80% 4,000€
50,001€ to 75,000€ 50% 2,500€
Over 75,000€ 0% No grant available


*The household income is calculated as the property owner’s gross taxable income in the previous tax year, together with that of his or her spouse or partner. Read more Domestic Waste Water Treatment Systems (Financial Assistance) Regulations 2013.
