COUNCILLOR QUESTIONS Report To Infrastructure Services Committee 8 September 2020 Infrastructure Services INFRASTRUCTURE SERVICES REPORTS ISC.09.1 WORKS PROGRAM - INFRASTRUCTURE SERVICES - WATER AND SEWER RESPONSIBLE OFFICER: Phillip Hood - Acting Director Infrastructure Services AUTHOR: Phillip Hood - Acting Director Infrastructure Services PURPOSE The purpose of the report is to provide an update on all works undertaken by the Water and Sewer teams over the previous month and those planned for the upcoming month. RECOMMENDATION That the Committee receive the report and note the information. BACKGROUND The report provides information to assist in addressing ratepayer enquiries regarding construction, maintenance and other activities in the area of Water and Sewer. REPORT/PROPOSAL Progress of major projects is listed in Attachment 1. All works relating to the Murrurundi Reservoir and Village Reticulation Projects are covered in a separate report. Project highlights from this month include (but are not limited to): Scone/Aberdeen/Murrurundi Water Supply Treatment Improvement Pathway o Public Works Advisory (PWA) provided UHSC with a new, draft project proposal to deliver on the Integrated Water Cycle Management (IWCM) Plan for the Shire’s water and sewer infrastructure. This is the highest level planning document that is a requirement of NSW Best-Practice Water Supply and Sewerage Management. UHSC have returned the draft proposal with comments, including Department Planning, Industry & Environment (DPIE) – Water input. o The IWCM will take into account the recent ‘Boil Water Alert’ and other supply and treatment concerns. The outcomes of the (yet to be undertaken) NSW Health facilitated Drinking Water Quality Management Workshop will also be included in the IWCM process. o UHSC are proceeding with the $1.7M UV, Pre-chlorination and Fluoride project with Hunter H2O currently putting together the technical specifications for an immediate D&C tender. NSW Health will fund any fluoride components, with a options analysis between different fluoride options being undertaken by Hunter H2O also able to be paid for by Health as a pre-construction activity. Upper Hunter Shire Council – Infrastructure Services Committee Agenda – 8 September 2020 Page 1 Report To Infrastructure Services Committee 8 September 2020 Infrastructure Services o UHSC are in regular discussions with DPIE in regards to our ongoing water supply and quality problems, the IWCM process, and the need for additional treatment improvements. o It is unlikely that a ‘full treatment’ or filtration plant will be approved or funded via the NSW Government ‘Safe and Secure’ Program until the above planning and assessment processes are undertaken as per ‘Best Practice’. o Once the appropriate planning tasks are completed, it would then be expected that DPIE will support UHSC through the design and delivery of the necessary additional treatment improvements. Aberdeen Hunter River Intake Improvements o GHD have provided the final report regarding the water supply works at Aberdeen. o While there are limitations to what improvements can be undertaken, nevertheless over $300,000 of potential works have been identified at the pump station that will assist in performance and reliability, in order to better manage ongoing water quality issues from Glenbawn Dam. o These works include 2 new pumps and 2 ‘overhauled’ pumps, new VSDs (variable speed drives), intake rehabilitation works and changes to pipework to improve the intake screen backwash function. o It is advised that the highest priority works – intake rehabilitation and purchase of new ‘Scone’ pump set – should be progressed immediately. o GHD have subsequently provided a variation proposal to develop concept upgrade designs and technical specifications for works to proceed ASAP. o Council have engaged GHD to proceed with this work, at the lump sum cost of $46,568. o Council will continue to seek ‘Safe and Secure’ or other funding for the Aberdeen Intake Works, but indications from DPIE are that this is unlikely to be successful. Cassilis Sewerage Scheme o Public Works Advisory (PWA) were engaged to develop separate Design and Construction Tenders for Council to progress this project, in addition to reviewing the overall cost estimate for the works. o Previous cost estimate from Cardno who completed the Concept Design was approximately $4.3M – far larger than the current project budget of $2.7M. Discussions with local civil contractors at the time indicated that the project budget would be sufficient to deliver the works. o However, PWA have estimated the total cost of works could be higher still – up to $4.9M (with contingencies). o Council staff have discussed the project issues with the Department Planning, Industry and Environment (DPIE) – Water, including consideration for additional funding being made available by the NSW Government’s Safe and Secure Program, though indications are this will be unlikely due to the small number of connections. o Council will continue to work with DPIE, PWA and our funding partners to find a funding solution. o In the meantime the Detailed Design tender is being advertised now, with a closing date of Monday 5 October 2020.
