OVERVIEW

This report is for Water Services activities for the period of 1 – 28 February 2021.

Significant items in this period include:

    No Lost Time Injuries were recorded for the month of February 2021. There were 7 incidents
     recorded for the month.

    Water consumption has increased slightly in the Mackay, Sarina and Marian/Mirani communities
     from January 2021 to February 2021, however, all communities remain under the residential water
     consumption target of 200 litres per day.

    There were 1,473 leak notifications issued for non myh2o members and 5,842 issued for registered
     myh2o members during February 2021.

    94% of Work Orders were completed within the allocated timeframe for January 2021 (recorded one
     month in arrears) which is above the target KPI of 90%.

    The Work Order breakdown provided for January 2021 (one month in arrears) shows a high number
     of water-scouring requests, this was prompted by the dirty water event in the city at the start of
     January 2021 together with the dirty water at Midge Point.

    There were two dry weather overflow events during the month of February 2021 with the first
     occurring at the inlet manhole to the Goldsmith Street Sewerage Pump Station and the second
     occurring at the Schmidtkes Road Sewerage Pump Station. These events were reported to the
     Department of Environment & Science (DES) with investigations undertaken to identify the cause.
     Investigation works have identified opportunities for improvement in SCADA monitoring and
     reporting and the completion of regular maintenance inspections.

    Biosolids produced at the Mackay South Water Recycling Facility (MSWRF) continue to return high
     values for chromium and nickel. Additional investigation work at individual pump stations is
     progressing to determine the source/s of metal contamination.

January 2021 Summary:
The number of Work Orders generated from Pathway requests to 31 January 2021 was 361.
94% of these Work Orders were completed within the specified target completion time.

3.3.   Water Requests Closed
When a customer lodges a request via the Call Centre, it is sometimes not reflective of the actual problem.
Therefore, the following graph shows the actual work undertaken and completed. The numbers of
Customer Requests will not always match the number of actions undertaken mainly due to multiple
customers reporting the one issue.
Please note, results are one month in arrears to allow for accurate reporting due the timing of completed work (i.e.,
a request received at the end of one month being actioned at the start of the next month).

January 2021 Summary:
The number of Work Orders completed for the reporting period was 808. This includes 172 Water Meter
replacements or new installations and 31 water-scouring requests. In a typical month there would be on
average 5 scouring requests. The significant increase in scouring during January 2021 was driven by the
dirty water event in the Greater Mackay Area in early January 2021 together with ongoing dirty water
issues in Midge Point throughout the month.

3.5.                                  Estimated Works
Water Services receives requests from customers for quotations to connect to Council’s infrastructure
(Estimates). It is important to note that many Estimates are requested by Developers in pre-planning of
future development stages. As a result, many of the Estimates completed do not result in requests for
immediate work to be undertaken. Also, of note is the fact that often requests are received for two block
subdivisions where clients seek to understand the total costs involved with subdivision before determining
their final course of action. In the instance where a client does not accept our initial estimate provided,
they can request a further breakdown of the fees and charges involved. On some occasions, clients may
be able to undertake certain aspects of the work themselves, however, Council always stipulates that any
live works undertaken on Council's water or sewerage infrastructure is only undertaken by Council. These
requests range from large subdivision development connections to a single service connection for a
property.
The following Chart displays the number of Estimates processed for customers for the reporting period
and the average time taken to complete. The Chart also shows the number of Estimated Works completed
and the average time taken for Water Services to complete the Estimated Works.

February 2021 Summary:
The number of sample batches registered during this period was 483 and the number of samples tested
was 1,167. The total number of tests performed was 33,634 for the month. Increased testing of
mechanical trade waste customers has been completed as part of an investigation into chromium and
nickel in the MSWRF catchment. There has also been an increase in testing associated with additional
raw and treated water monitoring works at Midge Point as part of the response to the dirty water issues
in the Scheme.

3.10. Leak Detection Notifications
Potential leak notifications are sent to customers when the leak is identified as greater than 10 litres per
hour (L/h). Notifications are sent by email, SMS and by post to those owners who have not signed up to
the myh2o portal and cease after three consecutive months of notification. Property owners signed up to
myh2o also receive notifications by email and/or SMS.

February 2021 Summary (25 January 2020 – 25 February 2021):
2,315 leaks were ceased for residential properties during the reporting period having an average of 10
days for the leak to cease (i.e. for the leak to be addressed by the property owner). However, there have
been leaks that commenced prior to 25 January 2021 that are still ongoing with an average of 61 leak
days.

2,356 residential property leaks commenced during the period.

The number of average leak days for residential properties decreased to 61 in February 2021. This could
have resulted from numerous factors; however, a significant contributing factor is the number of AMRs
replaced during the month (198); i.e. we are now receiving data for these replaced meters whereas data
was not being received previously and leaks were not being identified/reported.

492 leaks were ceased for non-residential properties during the reporting period having an average of 20
days for the leak to cease (i.e., for the leak to be repaired by the property owner). However, there have
been leaks that commenced prior to 25 January 2021 that are still ongoing with an average of 101 leak
days.

493 non-residential property leaks commenced during the period.

Considerable effort is devoted towards encouraging non-residential customers to fix the identified leaks,
however, some of these leaks are difficult to track down due to the size and complexity of the property.

January 2021 Summary:
There were seven drinking water samples above the recommended health based ADWG levels during
January 2021.

The Midge Point Water Supply Scheme recorded one result for E.coli during January 2021. This result
was reported to the Water Regulator. All follow up samples taken have been complaint with no further
instances of E.coli recorded in the Midge Point Water Supply Scheme.

The Bloomsbury Water Supply Scheme has recorded a total of six samples where the Chlorate levels
have exceeded the proposed Queensland Health Guideline Limit during the month. These exceedances
relate to the supply of out of specification Sodium Hypochlorite at the start of the month. The Sodium
Hypochlorite was replaced towards the end of the month resulting in an improvement to the Chlorate
levels.

January 2021 Summary:
There were nine drinking water samples above the recommended aesthetic ADWG levels for January
2021. The Midge Point Water Supply Scheme recorded two separate exceedances. The first for ‘True
Colour’ was where the result of 40 Hazen Units (HU) exceeded the Guideline Limit of 15 HU. The second
for ‘Manganese’ was where the result of 0.442 mg/L exceeded the Guideline Limit of 0.1 mg/L. These
exceedances are interrelated with the high manganese levels in the water causing a discoloration of the
water. The Midge Point water supply is sourced from Peter Faust Dam which contains naturally occurring
high levels of iron and manganese. The discolouration of the water is caused by a reaction between
these contaminants and chlorine resulting in the formation of particulates that can be seen in the water
as discolouration. These particles settle and form sediments in the pipes. Water turbulence caused by
periods of high demand in the Network can stir up the sediments resulting in bouts of dirty water. For this
reason, scouring of the Kelsey Creek to Midge Point Trunk Main will be undertaken during March 2021
which will help to remove sediments that have built up in the trunk main over time. This will reduce the
risk of future dirty water events. Unfortunately, dirty, or discoloured water may continue for a short period
of time following the completion of the Scouring Program as remaining sediment is flushed from the
system.
The Mackay and Sarina Water Supply Scheme had one exceedance with an ‘Iron’ result of 0.438 mg/L
exceeding the Guideline Limit of 0.3 mg/L.
There were three results for ‘Hardness’ which exceeded the Guideline Limit of 200 mg/L.
The first was in the Calen-Kolijo Water Supply Scheme where a result of 249 mg/L was recorded. Process
reviews are continuing at the aged Calen-Kolijo Water Treatment Plant to optimise water softening.
The other two results are attributed to the Koumala Water Supply Scheme with results of 353 mg/L and
394 mg/L recorded. At this stage, the Water Softening Plant at the Koumala Water Treatment Plant is
still expected to be completed by the end of the 2021 calendar year.
The Eton Water Supply Scheme also had three ‘Sodium’ results during January 2021 which exceed the
Guideline Limit (of 180 mg/L) these being 197 mg/L, 203 mg/L and 200 mg/L. These results are only
marginally above the aesthetic guideline and are related to the plant's softening process. No follow up or
action is deemed warranted at this stage as the results are within the operating range of Water Softening
Plant.
