Last update: January 2024
At Tricel, we are regularly asked by homeowners if there are septic tank grants available to upgrade their existing installation to a new wastewater treatment plant.
Currently, three types of grant schemes are available in Ireland.
What are the Septic Tank Grants Available in Ireland?
In 2013, the EPA launched its National Inspection Plan to inspect domestic wastewater treatment systems (better known as septic tanks) throughout Ireland. At the time, two types of financial help were available: the ones falling under the Home Renovation Incentive (HRI) and the ones falling under the Domestic Waste Water Treatment Systems (DWWTS) Scheme.
Since December 2019, the HRI grant has been closed to applicants and is no longer available. Only the DWWTS has been maintained by the Department of Housing, Planning and Local Government.
Who awards the DWWTS grant?
The responsibility for providing funding for the DWWTS scheme grant lies with the Department of Housing, Planning and Local Government (DHPLG). BUT it is the local authorities who administer the grant scheme on behalf of the department (under the Rural Water Programme).
Therefore, you should contact the Rural Water Section of your City or County Council for the application forms and further information.
Domestic Waste Water Treatment Systems (DWWTS) Scheme
There are three types of grant schemes available.
In January 2024, all three grants listed below have increased by 140% from €5,000 to €12,000.
Maintenance, servicing, and de-sludging are not eligible for grants.
- National Inspection Plan (NIP)
Under the National Inspection Plan, grants are available for remediating, repairing, upgrading or replacing septic tank systems that fail inspection by a city or county council. Local authorities will issue an advisory notice requiring the homeowner to repair the system. Grant applications will also be handled by the City or County Council.
Read more about the inspections and what to expect.
- Priority Areas for Action:
Grants are available for fixing septic tanks in these areas if they threaten the environment and need to be repaired, upgraded, or replaced. Local Authority Waters Programme Office will identify these systems and issue a letter confirming their eligibility. After that, the homeowner can apply for a grant from the City Council or County Council.
- High-Status Objective Catchment Areas:
In these areas, grants are available to repair, upgrade, or replace septic systems threatening the environment. By entering your EIRCODE in an interactive map, you can determine if you are in one of these areas and apply for a grant from the City or County Council.
See below the summary table.
