1 Commercial and Industrial Metering

1.1 Installation requirements for meter sizes 32 mm and above

Only Barwon Water supplied and approved meters will be accepted on meter installations an must comply with the National Measurement Act as administered by the National Measurement Institute’s specifications and codes, be compliant with NMI R49-1 and AS 3565.

Meters shall be installed in accordance with AS/NZS 35001; and AS 28452, and Barwon Water, Metering Policy.

No water meter or fire service leak detector check valve with by-pass meter shall be placed in a location that creates an OH&S issue for either the public or Barwon Water personnel, limits access or is a “Confined Space”.

No water meter is to be located near or in an electrical cabinet or electrical control room.

1.2 Backflow

To protect the water supply system and the public from any potential backflow incidents Barwon Water requires all new connections and existing medium and high hazard rated properties to install a “Backflow Prevention Device (BPD)” at the water meter assembly. The BPD/s shall be appropriate to the development type as specified in AS/NZS 3500, and must be of a rating which is equal to or greater than that required to protect a zone and or individual hazard within the development. If the BPD is a testable device then it must be tested in accordance to AS/NZS 2845 at commissioning stage of the meter installation.

(a) If a testable Reduced Pressure Zone (RPZ) device is installed, the relief valve of the RPZ must be a minimum 300mm to and above the natural ground

1.3 Valves

Resilient seated flanged gate valves are required for all meter assemblies 80mm DN and over. If Dura butterfly valves are used, they must be either flanged or lugged type and they must also have a geared spindle.

NOTE: Quick shut off valves, sandwich or wafer butterfly valves are not acceptable.

1.4 Meter assembly set up – general requirements

(a) Barwon Water requires meters DN 32 or larger be set at a minimum height of 300mm and supported independently of piping supporting the meter in a horizontal position.

(b) All meters assemblies shall be installed in a horizontal position and correctly supported inline with AS/NZS 3500.

(c) The meter is installed with the dial face in a position where an unassisted person standing on the floor can easily read it.

(d) All installations DN 32mm and greater must be fitted with a test ferrule immediately down stream of the water meter and prior to the outlet valve.3

(e) The RPZ relief valve must to be 300mm be above the natural ground

(f) No Branch pipe is closer than the lower outlet bend of the water meter assembly

(g) All meters installed in industrial or commercial buildings must at all times be provided with clear safe access around the water meter to enable reading, testing, inspection, maintenance and exchange at all times. This may include a secured fenced area with external access via gate.

December 2017 A12709213 4

(h) The water meter including the pipes and fittings must not be embedded in concrete formwork or concrete walls.

(i) Meters shall be installed within 7 days (1 week) of issue.

1.5 Meter selection and application guide – 32 mm to 150mm including (Magflow)
