Regulations & Licensing
Septic Tank Regulations
What the regulations mean for you
- If you own a domestic wastewater treatment system, you are required to have registered it with the Department of the Environment, Community, and Local Government by the 1st of February 2013.
- Inspectors who have been appointed and approved by the EPA will carry out inspections on behalf of Local Authorities
- Inspections will start in 2013 and will at first concentrate on areas with high risk to the environment and public health - where drinking water sources or habitats are at risk from wastewater discharges.
- Your local authority will notify you if your domestic wastewater treatment system is to be inspected.
- If the inspector finds that your system is working properly and being maintained correctly, you need take no extra action.
- If there are any issues, you will get an advisory notice from the local authority, requiring you to improve the maintenance of your system, or to upgrade or remediate it.
- Any remediation work required will be based on factors such as the nature of the problem, the extent of risk to public health or the environment, existing site size and the hydrological and geological conditions present.
- You may be able to get a grant to help with the cost of the work required. The grant is means-tested and you must have registered by 1 February 2013 to be eligible.

Anua's range of septic tanks for single houses and larger developments are designed and manufactured to the highest standards and are the only septic tank in Ireland with EN 12566-1 Certification.
Septic tanks are available in the spherical (onion) shape as shown on the right or as a low profile, horizontal cylindrical tank.
The Anua Septic Tank is constructed from GRP as a singular tank for ease of installation and ongoing operation. All units are made from strong, chemical-resistant watertight Glass Reinforced Plastic (GRP) and are backed by Anua’s expert service team.
Deeper inverts are available where required. For ease of installation and depending on site conditions, concrete or granular backfill can be used.
Anua’s Septic Tanks may also be provided with integral pumping arrangements. This can be a a single pump installation incorporated within the tank itself or additional chambers providing single or twin arrangements as required.

How it works
A septic tank is the most economical solution where connection to mains drainage is not available. In a septic tank, household wastewater is stored allowing solids to settle to the bottom. Bacteria digest these solids, which reduces their volume. The excess liquid remaining after this process is then discharged to the drain field.
- Raw sewage enters the first stage of the tank where solids settle by gravity to the bottom of the tank.
- Sludge levels reduce within this stage with the aid of naturally occurring anaerobic digestion.
- The flow passes upwards through further baffl e arrangements providing further clarification.
- The settled effluent is displaced from the tank by the incoming sewage flow.
- The partially treated effluent then flows into the percolation area or other suitable filter bed system. Anua may also supply a filter bed system: see our Puraflo product for further details.
- Sludges that build up in the base of the tank are emptied annually to ensure continued efficient running.
Anua will advise you on the correct unit size for your project.
Septic tanks can be used on their own where there is sufficient land available for an adequate drain field. Such tanks partially treat the sewage and rely on the soil in the drain field to continue the treatment process.
A septic tank may not always be suitable for your site. A septic tank may not suit when:
- Soil condition is poor
- There is proximity to watercourses
- There are building regulation factors.
A wastewater treatment system may then be required to provide enhanced treatment performance.
Brochures & specifications
- Provision should be made for tanker access for the annual desludge visit.
- Drainage Fields should be designed to the requirements of EPA Code of Practice
- To establish the correct drainage area required a percolation test should be carried out.
