CANBERRA SEWERAGE AND WATER SUPPLY REGULATIONS (AMENDMENT) 1987

EXPLANATORY MEMORANDUM

No. 19 of 1987

Section 4 of the Building and Services Ordinance 1924 provides that the Minister may make regulations concerning the use and management of the Canberra sewerage and water supply systems.

The Canberra Sewerage and Water Supply Regulations (Amendment) 1987 requires the use of backflow prevention devices when work performed on the Canberra water supply system under regulation 100 of the Canberra Sewerage and Water Supply Regulations is likely to introduce dangerous substances into that water supply.

Regulation 100 requires a person to obtain a permit before uncovering Commonwealth pipes or working on pipes communicating with Commonwealth pipes.

New regulation 100A(1) provides that the Engineer for Water Supply shall not grant a work permit under regulation 100 for work on the Canberra water supply if the work is likely to introduce dangerous substances into that water supply unless he or she is satisfied that an appropriate backflow prevention device will be installed to prevent the dangerous substances entering the Canberra water supply.

Sub-regulation 100A(2) provides that the type of backflow prevention device required will depend on the danger posed by a potential hazard.  Where the backflow prevention device is to prevent:
•	a hazard listed in the Table, the devise is to be that specified in the Schedule or otherwise approved by the Engineer; and
•	in relation to any other hazard the device is to be that approved by the Engineer.
