Important Notice

S.R. 66 Certification Published by PIA

The Dept. of Housing, Planning, Community and Local Government has amended the Technical Guidance Document H (TGD H) – Drainage and Waste Water Disposal to reference S.R. 66 and remove references to national annexes.

These amendments to TGD H will become effective from 1st January 2017 and it should be noted that all works started after that date involving small wastewater treatment systems will have to comply with the requirements of S.R. 66.

This means that all waste water treatment products must be in compliance with S.R. 66 to be eligible for use in Ireland.

The objective of this S.R. is to provide guidance to designers, manufacturers and installers when selecting a wastewater treatment system for populations of up to 50 PE in Ireland.

One of the most notable additions is the updated certificates produced for Part 1 and Part 3 by PIA under direction of the Dept. of Housing, Planning, Community and Local Government based on S.R. 66.

The updated certificates have the following notable additions:

1.         Number of Desludging – S.R. 66 compliant certificates shall have the response: ‘not more than once’

2.         A range of approved plants within in a manufactures range are now attached to the new certificate to allow a designer to more easily confirm suitability and compliance for a particular site.

(Note: A particular model offered prior to 1st January 2017, but not due for installation until after that date is deemed as non-compliant unless it has been approved and attached to the manufactures new certification.)

To view the new list published by PIA see:

This S.R. should be used in conjunction with the appropriate part of the I.S. EN 12566 series of standards and the Code of Practice entitled Wastewater Treatment and Disposal Systems Serving Single Houses (PE < 10) published by the Environmental Protection Agency in 2009.



The Sepcon BAF system fully complies with the new S.R. 66 amendments.
