4.10 Meters and Flow Restrictors
4.10.1 Meters for on demand metered supplies, and restrictors for restricted flow supplies shall be supplied, installed and maintained by the Water Supply Authority. These devices shall remain the property of the Water Supply Authority.

4.10.2 For on demand supplies which are not metered, the Water Supply Authority reserves the right to fit a meter and charge accordingly where it considers water use is unusually high.

4.10.3 Meters and restrictors will be located in a position which is readily accessible for reading and maintenance, and if practicable immediately on the Water Supply Authority side of the point of supply, (see Figure 7 of this part of the bylaw).

4.10.4 The accuracy of meters and restrictors shall be tested as and when required by the Water Supply Authority to ensure performance within ±4 % of its reading (meters), or within ±10 % of its rated capacity (restrictors).

4.10.5 A customer who disputes the accuracy of a meter or Restrictor may apply to the Water Supply Authority for it to be tested provided that it is not within three (3) months of the last test. If the test shows non compliance with the accuracy requirement above then the customer will not be charged for the test. If the test shows compliance then the customer shall pay a fee in accordance with the Water Supply Authority current schedule of rates and charges.

4.10.6 Meters shall be tested by running a measured quantity of not less than 400 litres through the meter in accordance with BS 5728: Part 3 (refer to Appendix 1 of this part of the bylaw). Restrictors shall be tested by measuring the quantity that flows through the restrictor in a period not less than 1 hour at its normal operating pressure. A copy of independent certification of the test result will be made available to the customer on request.
Return to top

4.10.7 Should any meter, after being tested, be found to register a greater or lesser consumption than the quantity of water actually passed through such a meter the Water Supply Authority shall make an adjustment in accordance with the results shown by such tests backdated for a period at the discretion of the Water Supply Authority but not exceeding twelve (12) months, and the customer shall pay a greater or lesser amount according to such an adjustment.

4.10.8 Should any meter be out of repair or cease to register, or be removed, the Water Supply Authority shall estimate the consumption for the period since the previous reading of such meter, (based on the average of the previous four billing periods charged to the customer) and the customer shall pay according to such an estimate. Provided that when by reason of a large variation of consumption due to seasonal or other causes, the average of the previous four billing periods would be an unreasonable estimate of the consumption the Water Supply Authority may take into consideration other evidence for the purpose of arriving at a reasonable estimate, and the customer shall pay according to such an estimate.

4.10.9 If metering indicates a significant increase in consumption to a premises, which is established as being caused by a previously unknown leak, the Water Supply Authority may estimate consumption as provided above, providing that the customer repairs the leak with due diligence.
Where the seal or dial of a meter is broken, the Water Supply Authority may declare the reading void and estimate consumption as provided above.

4.10.10 Where a situation occurs, other than as provided for in subclause 4.10.8 of this part of the bylaw, where the recorded consumption does not accurately represent the actual consumption on a property then the account shall be adjusted using the best information available to the Water Supply Authority. Such errors include, but are not limited to, misreading of the meter, errors in data processing, meters assigned to the wrong account, and unauthorized supplies.

Provided that where an adjustment is required, in favour of the Water Supply Authority or the customer, this shall not be backdated more than twelve (12) months from the date the error was detected.

4.11 Disconnection
The supply of water to any customer may be disconnected (or have the flow restricted in some way) by the Water Supply Authority in the event of:
a) Failure to pay the appropriate charges by the due date;
b) Failure to repair a leak, or in any way wilfully allow water to run to waste or be misused;
c) Interference with the Water Supply Authority supply system;
d) The fitting of quick-closing valves (subject to clause 5.1 of this part of the bylaw);
e) Failure to prevent backflow (refer clause 5.11 of this part of the bylaw);
f) Non-compliance with, or breach of, any other requirements of these terms and conditions.
Refer to clause 6.1 of this part of the bylaw for disconnection and reconnection procedures.
