Water & Sewer

Water

Potable water supply to Narromine and Trangie and Tomingley.

Potable water supply schemes are in operation in Narromine Shire, Narromine, Trangie and Tomingley. These systems supply drinking water in accordance with the NSW Public Health Act of 2010 and the subsequent 2012 Regulations and delivered to the microbiological standards set within The Current Australian Drinking Water Quality Guidelines.

All three systems are supplied through a total of 56.5kms of reticulation mains plus house services.

Sewerage

The sewer is reticulated through a total of 40 kms of reticulated mains and 10 kms of rising mains for the two schemes and then treated to a quality that adheres to Protection of the Environment Operations Act 1997.

Pollution Incident Response Management Plan

Narromine Shire Council (Council) operates a sewage treatment plant (STP) for each of the townships of Narromine and Trangie NSW. 

The purpose of this plan under Part 5.7A of the POEO Act requires all holders of an environment protection licence (EPL) to prepare, keep, test, and implement a Pollution Incident Response Management Plan (PIRMP).

The objectives of the plan are to:

• Minimise and control the risk of a pollution incident at the facilities.
• Ensure comprehensive and timely communication about a pollution incident to all stakeholders.
• Ensure staff are properly trained in the plan so that it is properly implemented and maintained.

This plan is extended to cover the operations of the Trangie STP as it has similar risks of pollution incidents and comes under the same management and control as the Narromine STP.

The EPA has not required Council to prepare a PIRMP for the Trangie STP under Section 153B of the POEO Act. The requirements to report material harm under Part 5.7 of the Act applies to all activities whether an EPL is in force or not.
