Connect to an urban water main

Meters must not be in pits, must be located a minimum of 300 mm from trafficable surfaces, maintain 150 mm clear space above, below, and around the meter, maintain unrestricted access for GWMWater inspection and maintenance, and be located a minimum of 300 mm and a maximum of 2000 mm inside the lot boundary fronting the GWMWater water main.

Where installed, backflow prevention ports require 300 mm clear space below.

Multiple-rated properties and properties with frontage via common property to the GWMWater main may utilise a common tapping via a meter manifold located within common property with a valve at the property boundary between the main and manifold.

The above standard connection requirements apply, with minimum spacing of 150 mm between meters, and a maximum of 6 water meters per manifold.

Table 1: Common tapping & meter manifold size guide.

Where there are more than 12 rated properties, GWMWater will consider proposals for sub-metering at GWMWater’s discretion on the basis of limiting congestion of water service pipes within the property. In such cases:

• A parent meter is required. The service point is the parent meter; performance of GWMWater’s service obligations is measured at this location regardless of performance at the sub-meter.
• The sizing of infrastructure must be supported by hydraulic calculations demonstrating the infrastructure will supply all sub-meters with sufficient flow as per the GWMWater Urban Customer Charter.
• Sub-meters must be located outdoors, or within a radio-transparent cabinet and maintain GWMWater’s unrestricted access.
• Sub-meters must not be in pits, must be located a minimum of 300 mm from trafficable surfaces, maintain 150 mm clear space above, below and around the meter, and must be located up to 1 m inside the sub-metered property, or within common property.
• GWMWater own and maintain: the service connection pipe between the main and the parent meter; and the parent meter; and the sub-meters; and the metering communication devices. All other common infrastructure is owned and maintained by the property owner(s) and must be listed on the owners corporation schedule (if applicable).
