The average leak days shows the average number of days a leak exists before any action is taken by

the customer to rectify. The average leak days for ceased leaks shows the average number of days

that the leak exists before being repaired.

April 2018 Summary:

The Average Leak Days (current leaks) for residential customers has decreased but has increased for

non-residential customers during April 2018. The difference between non-residential and residential for

current leak days is 141 days. The Average Leak Days (Ceased Leaks) show that the residential

customer has the leaks repaired within 16 days on average, whereas, the non-residential customer

takes 25 days to have leaks repaired on average. Considerable effort is undertaken with non-residential

customers to encourage attention to fix the identified leaks, however, some of these leaks are very

difficult to track down due to the size and complexity of their property.

REGULATORY COMPLIANCE

5.1. Drinking Water Compliance

Potable water is provided in accordance with the requirements of the Water Supply Safety and

Reliability Act, measured against the Australian Drinking Water Quality Guidelines. Drinking Water

samples are taken at the outlet of Water Treatment Plants and at various locations within the reticulation

network. Please note: These results are reported one month in arrears. A summary of the performance

is detailed below.

March 2018 Summary:

Eton reticulation samples for Selenium continue to be in the range of 10-13 ug/L.

March 2018 Summary:

Eton and Koumala continue to have high values for the aesthetic parameter of hardness (>200 mg/l)

with values ranging from 369 mg/l to 402 mg/l for Eton and around 380 mg/l for Koumala. These

hardness levels will be addressed in the future with the planned provision of water softening plants as

part of each Scheme.

5.2. Wastewater Compliance

The discharges from wastewater treatment facilities are regulated by Development Approvals issued

by the Department of Environment and Heritage Protection. The licence requirements differ based on

the year the Development Approval was issued and the receiving environment associated with

discharges.

April 2018 Summary:

A wastewater test for Mirani Sewerage Treatment Plant was noncompliant with release limits to the

receiving environment for pH and faecal coliforms. This relates to algae pushing the pH up in the re-

use dam and birdlife utilising the dam contributing to the high faecal coliform result.

5.3. Backflow Testing

Backflow devices are installed on water services where there is a risk that water could return from a

private property back into the Water Reticulation network. The requirement for backflow devices is

regulated in accordance with the Standard Plumbing and Drainage Regulation.

April 2018 Summary:

18 new devices were registered while six devices were cancelled during April 2018. Council performed

seven tests on backflow devices in April 2018.
