National Inspection Plan 2018-2021 - Domestic Waste Water Treatment Systems

The Environmental Protection Agency has published the National Inspection Plan 2018-2021: Domestic Waste Water Treatment Systems.

The aim of the Plan is to protect water and human health from the risks posed by domestic waste water treatment systems. Since the plan was first developed in 2013 it has been based on a two strand approach of engagement strategies linked with risk based inspections.

This third plan has been prepared for the years 2018 to 2021. The risk based methodology has been updated taking the following into account:
- The additional information on water quality gathered during the preparation of the River Basin Management Plan 2018 - 2021.
- Experience gathered from the engagement activities and inspections; and
- Submissions received during the consultation period.

The Plan maintains a minimum of 1,000 inspections per year. This is in line with the risk posed by domestic wastewater treatment systems on a national scale compared to the number of water and waste water related inspections carried out in other sectors regulated by local authorities. Each Local Authority is required to complete the minimum allocation of inspections assigned to them as set out in Table 3.1 of the Plan. Local authorities may carry out additional inspections where there is evidence that domestic wastewater treatment systems are posing a significant risk locally.

The EPA will continue to report annually on the implementation of the NIP. The most recent report can be found at
