Domestic Waste Water Treatment Systems: DWWTS Inspections and Enforcement 2019 by the EPA.

Overview

​DWWTS are Domestic Waste Water Treatment Systems, most commonly known as septic tanks or wastewater treatment plants. They are used by households to treat wastewater when a connection to the mains is not possible.

If not built, operated or maintained properly, DWWTS can pollute the environment, such as nearby rivers, lakes and coastal water. A faulty wastewater treatment system can also contaminate household wells with harmful bacteria and viruses.

Since 2013, the National Inspection Plan (NPI) has been put in place for local authorities to inspect over 1000 systems each year. Additional assessments are being carried out by specialist local authority teams in priority areas to identify DWWTS that may be a risk to water quality. This is part of the actions set out in Ireland in the River Basin Management Plan 2018 – 2021 to protect and improve rivers, lakes and coastal areas.

The summary below relates to the 2019 results and report by the EPA.

If your current wastewater treatment system is leaking and you’re looking for a replacement solution, get in touch with us today to discuss your project, requirements, and what solutions are available to you.

We would recommend you also take on a maintenance contract with Tricel or its agents/distributors to ensure your wastewater treatment system is kept in good working order.

Please note that desludging should always be done by a licensed waste collection company. More information on our dedicated page.

DWWTS Inspections and Enforcement 2019, the Local Authority Enforcement

The local authorities have issued advisory notices requiring the systems that fail inspection to be fixed. Efforts are being made for failures to be fixed as well as older unresolved issues. Some local authorities have taken legal actions for failure to fix DWWTS since the NPI started.

Householders, what should you do?

In order to make sure people’s health and the environment are not at risk, householders should ensure that DWWTS are:

  • Built properly
  • Maintained including desludging
  • Wells are tested (to protect the health of your family)

The last point is especially relevant is if your wastewater treatment system is located near a well, or if the effluent is ponding in the garden or being discharged to ditches/streams.
