Various sections of Part 3 - Sewerage

Insert Amdt Record at front following Revision Record

6.2.2

42

Delete Paragraph 4:

“The tie should generally… lowest corner of the block.”

Insert the following as Paragraph 4 of Clause 6.2.2:

“Where possible, the tie should generally be located on the sewer at 1.0 metre from the lowest corner of the property. However, it is permissible to locate the tie at a position other than the lowest corner of a residential block provided that

• no more than fourteen (14) residential dwellings, and
• no non-residential leases,are serviced upstream of that block.

In such circumstances, particular attention must be paid to the requirements of Clause 6.2.1 regarding the maximum permissible depth of a sewer tie, and also to the requirements of Clauses 4.2 and 6.2.1 relating to the servicing of an entire lease.”

Insert the following as Paragraph 8 of Clause 6.2.2:

“No more than three (3) consecutive service ties on a reticulation main are permitted to cross a roadway unless specifically approved by ACTEW.”

Part 2 - Water

6.2

22

Delete Paragraph 4:

The number of water supply connections to a lease shall be:

• one connection to a single residence or single unit non-residential development;
• two connections to a residential dual occupancy or two unit residential body corporate, with the meters co-located;
• one connection to each unit in a multi-unit residential or multi-unit non-residential development where all units have an accessible public street frontage; and
• one connection only to a multi-unit residential or multi-unit non-residential development where one or more of the units does not have an accessible public street frontage;

A separate un-metered fire service may be required where metering requirements for a combined domestic and fire service are incompatible or are likely to cause water quality problems.

When a new water connection is required to replace existing services, the existing services must be disconnected at the developer's cost before the new water connection is provided.

• one meter on each connection immediately downstream of ACTEW’s isolation valve at the block boundary;
• one meter for each unit in a multi-unit development (both residential and non-residential);
• a separate meter for common property water usage.

Although these requirements are not retrospective, it is ACTEW’s policy to permit existing developments to adopt these standards where ever possible, but at ACTEW’s discretion.

The connection protocols for different circumstances are described in ACTEW’s Water and Sewerage Service and Installation Rules.

Developments that are required to install multi-unit metering will have a condition placed on the planning approval.

The hydraulic designer must ensure that the design of the internal hydraulic systems provides protection against noise, shock wave transfer and cross contamination between the dwellings.
