Plumbing and Drainage Requirements

On-site plumbing works within the Central Coast region require an inspection by Central Coast Council.

The Plumbing and Drainage Act 2011 established a single scheme regulation for on-site plumbing and drainage work in NSW, and designated NSW Fair Trading as the NSW plumbing regulator from 1 January 2013.

Process for undertaking plumbing and drainage works

1. Submit plumbing and drainage inspection application

A plumbing and drainage inspection application form should be submitted, with payment of the applicable fee(s), for all plumbing and drainage works. The form can be submitted by an owner, builder, plumber or other relevant person.

2. Submit notice of work

At least two days before a plumber starts work on a property, the plumber must provide council with a notice of work.

The notice of work must be signed by a licensed plumber. If fees have not been paid, they must be paid upon submission of the notice of work. If fees have been paid, the receipt number should be written on the completed notice of work.

Requirements for building over sewer and stormwater drainage, and adjacent to water mains

Where a developer proposes to construct works in the vicinity of water or sewer mains, they must comply with requirements outlined in the Building Over or Near Council Sewer and Water Mains Guidelines. A fee applies where engineering plans are required to be assessed by the Water Authority.

Backflow

An important way town water can be protected is to prevent the backflow of water from premises considered to be a potential risk of cross contaminating town water with polluted water. Town water in these circumstances can be protected by installing a backflow prevention device. Council require a backflow prevention device be installed by an accredited licensed plumber at the property boundary and registered with Council. Lodgement of an water supply backflow prevention form and payable fee are required.

It’s a requirement that testing of the device be conducted on an annual basis and results submitted to Council each year.
