Small Private Supplies

Small Private Supplies, involved in the provision of water to the public, are legally obliged to have Water Quality tests undertaken, outlined in S.I. 278 – Drinking Water Regulations (2007).

What types of tests are required?

Compliance monitoring:

Two different types of tests are required, measuring a range of parameters. These tests are titled ‘check’ (a ‘check’ comprises some  ‘microbiological’, ‘indicator’ and ‘chemical’ parameters) and ‘audit’. (‘Audit’ comprises all parameters from the Microbiological, Chemical and Indicatory categories covered in the 2007 Drinking Water Regulations). Frequency for both categories is based on volume used per day/consumers on the supply.  Data from this category is returned to the EPA on an annual basis and forms part of the annual drinking water returns from Offaly County Council.

Operational Monitoring:

This category comprises E.coli, Coliform Bacteria and Clostridium perfringens and can change pending changes in water quality. Results are used to assess water treatment and will demonstrate if chlorine dosing is being managed effectively. Results from this category will not be returned to the EPA.
