Homeowners who need to upgrade their septic tank will no longer be means tested in ‘high status water bodies’ areas, delegates at the Irish Onsite Wastewater Association conference heard yesterday (13th December 2018).

Ruth Hennessy of the Local Authority Waters Programme told delegates the full details had yet to be finalised by the Department of Housing, Planning and Local Government but are expect to be rolled out early next year.

“The Department are yet to finalise the revisions to the septic tank grant scheme so we cannot be certain that they will be extended to everyone in high risk areas. Based on recent discussions this is likely but still uncertain,” Hennessy said.

She added the grant would apply to all homeowners, regardless of income level, that are in a high risk area. You will no longer have to fail an inspection to be elgible for the grant in these specific areas.

The current grant system is means tested and does not apply to regular system maintenance such as desludging. The current grant levels cover 50 per cent (income level of €50-70k) to 80 per cent (income level of up to €50k) of the cost of repairing, upgrading or replacing a septic tank that failed a local authority inspection. The maximum grant currently availble is €4,000.

Hennessy told Selfbuild it was likely that the grant in these high risk areas would be at the €4,000 mark regardless of income level. The grant will continue to be for works to upgrade or replace the failing septic tank that is leading to water pollution. The grant will continue to not apply to desludging, for example.

Local authorities inspect septic tanks and every year roughly half of all septic tanks inspected fail. The latest figures presented by the Environmental Protection Agency at the conference confirmed this trend.

Since 2013 work has been ongoing to evaluate the water quality of Irish rivers, with 1,4000 out of roughly 5,000 deemed at risk. Of these 800 sections have been prioritised for cleanup in 190 priority areas.

The recently established Local Authorities Water Programme is in charge of further investigations and community engagement to reduce water pollution levels in priority areas.

In addition to agriculture, poorly functioning septic tanks have been found to be a main pressure on water quality. In 40 areas they were considered to be the only cause of water pollution.

UPDATE 8th February 2019: Means testing scrapped, grant levels increased. All houses within ‘high status’ water areas and ‘prioritised areas for action’, as identified in the River Basin Management Plan for Ireland 2018-2021, will qualify for the grant. According to the Department of Housing:

The means test that previously applied to this grant scheme is being removed and the level of grant support is being increased to 85 per cent of the eligible costs of installation/upgrade or €5,000 (up from €2,500/€4,000), whichever is the lesser.  This represents an increase of 25 per cent and 100 per cent, respectively, relative to the current maximum grant levels.


At Selfbuild Live Dublin find out more about the septic tank grants. Selfbuild Live Dublin, 13th-15th September takes place in the Citywest Convention Centre, Dublin.


In 2017, payments totalling some €200,000 were made by the Department to local authorities to recoup payments made to households under the grants scheme.  Provision of €1.25 million is made for 2019.  This will be kept under review throughout 2019, having regard to the emerging level of demand. The operation of the new arrangements will be reviewed later in 2019.

Meanwhile grants for private wells have also been increased; under the current scheme a person is eligible for a grant if they are providing a piped supply of water to a house for the first time or carrying out improvements to a seriously deficient existing piped supply of water to a house. The vast majority of grant applications are for improvement works.

Currently a grant of €2,031 per house or 75 per cent of the approved costs, whichever is the lesser, is available.  The minimum grant threshold for an application is €635.  Eligibility for a grant is currently not subject to a means test.  The dwelling must be a minimum seven years old.  If a grant is approved, another application cannot be made for a further seven years.

Following an examination of the current arrangements, consultation with stakeholders including local authorities, the Environmental Protection Agency and the Health Service Executive, and consideration of the matter by the Working Group, the following changes have now been agreed:

  • A maximum grant for rehabilitation works of €3,000, which represents an increase of 47 per cent on the current maximum grant amount.
  • Where the local authority agrees that the most appropriate solution is to provide a new well, the maximum grant payable would be €5,000.
  • Recognising the role of the grant in improving quality, the water quality treatment element (typically filtration and UV filtration) will qualify for 100 per cent funding up to a maximum of €1,000.
  • Up to 85 per cent of other costs would be met, subject to the total combined maximum costs of €3,000 for well rehabilitation or €5,000 for a new well. Applicants would not be able to avail of both grant amounts i.e. they would not be able to avail of €3,000 for well rehabilitation as well as the €5,000 for a new well.
  • The qualifying age of a house before an application can be made is to remain at 7 years.  The period before a further application can be made is also remaining at 7 years.  As an additional feature, applicants would be permitted to make a second application if the maximum grant was not fully utilised within the seven year period. This might include, for example, cases where some significant unforeseen or emergency issue arises after the first application.
  • A minimum grant threshold will remain – but will be raised from €635 to €750.
  • The scheme is to continue to be demand-led, subject to an overall limit in funding to be determined annually under the multi-annual programme.
  • The costs in 2018 were some €2.76 million.  Provision of €4 million is being made for 2019.  This will be kept under review throughout 2019, having regard to the level of demand.
