WASTEWATER TREATMENT

Septic Tank Regulations in Ireland

OVERVIEW

In Ireland, many rural houses lack connection to the main sewer, instead, they have their own domestic wastewater treatment system to collect, treat and discharge their wastewater.

Septic tanks are a type of wastewater treatment system along with wastewater treatment plants.

As the wastewater collected comes from toilets, showers, sinks, washing machines, dishwashers, etc., one can find a number of different pollutants contained within. For this reason, in cases where the domestic wastewater treatment system is not designed correctly or appropriately operated, the effluent can pollute the local environment.

Such issues result in damaged wells or water sources and cause problems for public health.

For this reason, Septic tanks are regularly inspected by the Environmental Protection Agency.

Septic tank regulations in Ireland, How do you maintain your Septic Tank?

To maintain your domestic wastewater treatment system, septic tank or wastewater treatment plant, you need to know where its located. This knowledge needs to also include the percolation area, drainage field or secondary or tertiary treatment plant.

You should also make sure of the following:

Usage and maintenance of the system are fit for purpose and fully operational.
Make sure the system does not pollute (leaking waste or discharging waste) directly into the ground or water source.
Rainwater (roof or surface) shouldn’t enter the wastewater treatment plant.
Don’t forget to de-sludge (empty) at recommended intervals. Please refer to the manufacturer guidelines as intervals will vary depending on the septic tank/wastewater treatment plant capacity and the number of people living in the house. De-sludging should always be carried out by an authorised contractor, and you should keep the receipt for five years.

What to expect from a Septic Tank inspection?

The development of a national inspection plan, as well as reporting, is the responsibility of the EPA. These inspections concentrate on the areas with a high risk to the environment or public health. We also carry out checks in lower-risk areas at a lower rate.

Local authorities organise the inspections and will notify you if one is to be carried out. The inspectors are appointed and approved by the EPA. They carry identification and produce it to householders on request.

During the inspection, checks are carried out on the following:

If you have your system’s registration
If it is leaking
If the components are in working order
If the effluent is ponding on the surface of the ground
If the wastewater treatment system is discharging directly to surface water without a license
If the effluent is treated adequately or being released directly to groundwater
If rainwater or clean surface water is entering the system
If you maintain propertly the wastewater treatment system if it is operating well
If it has been de-sludged
If the system adversely affects the environment due to poor management

What if my system isn’t working correctly?

If you correctly manage your system and everything is working efficiently, there is requirement from your side, just keep up the excellent work! You will receive a copy of the report confirming compliance.

However, If the inspector finds that improvements are necessary, he will inform you. You will also receive an advisory notice from your local authority within 21 days, requiring you to improve the maintenance of your system or to upgrade or remediate it.

If you have to carry out remedial work, you may be eligible for a grant. The grant is means-tested, you must have had your wastewater treatment system registered by the February 1, 2013 to be eligible. For more information about the grants, visit the Department of Housing, Planning and Local government’s website.
