All our current projects are listed in our Corporate plan and strategic business plans. The current projects are initiated for a number of reasons including:
- Improving the service we provide you and the quality of our products
- Making sure our systems can support population growth and increased demand
- Proactively maintaining and repairing our networks so they don’t break
- Reducing risks around safety or environmental impacts
- Reducing our impact on the environment through recycling and reuse
- Compliance with regulations
For more on our current and future projects please refer to our Corporate Plan 2019 – 2024
Cowes Waste Water Treatment Plant upgrade
The major upgrades for this project includes the construction of a new 24m diameter clarifier, refurbishments of the existing clarifiers and associated works. This will also include EPA works approval, functional design and tendering.
Phillip Island Water Supply Security Project
Westernport Water has assessed redundancy options for our water supply (648 water main) across Phillip Island. This project includes construction of a storage tank in the Cowes water supply zone providing service reliability and operational flexibility.
Sewer Junction Rebuild Program
Westernport Water has 14753 customers connected to our sewerage collection system. Nearly 50% of these connections were constructed in the 80’s and are approaching 40 years. We are responsible for maintaining the sewerage service from the sewer junction inside the properties. As a preventive maintenance activity, Westernport Water conducts CCTV investigation program for selected areas, the purpose of the program is to monitor condition of our sewerage collection system or potential blockages due to tree roots (root ingress).
The Sewer Junction Rebuild Program is an ongoing program for reconstruction or relining of collapsed sewer junctions as a result of blockages that could result in service interruptions or sewer spills.
Water Main Replacement Program
Westernport Water has 460.5km of water pipelines in our distribution network and approximately 178km (40%) of our water network consists of Asbestos Cement (AC) mains. Well over half of these (100km) have passed age 50 years and will reach the end of their theoretical useful life for an average AC main.
An investigation was conducted into the condition assessment of AC pipes using a non-destructive testing method. A pipe replacement program has been developed using multi-criteria assessment techniques which include pipe-type, age, pipe diameter, criticality, condition and fault history. Based on this detailed assessment, a multi- year AC water main replacement program has been developed. From 2018-2022, all AC pipes (approximately 11kms) with ‘Condition 5 rating’ and ‘High Criticality’ will be replaced.
Water Quality Continuous Improvement Plan
Backflow prevention program
Backflow is identified as a potential source of contamination to the distribution network. This program roll out will start with the agricultural sector then move onto commercial and industrial customers.
Distribution system maintenance
Repairing a water main after a burst or leak has the potential for microbial contaminants to enter the distribution network resulting in illness. To improve management of repairs we will adopt the industry best practice 5C principle to water hygiene. The Water Quality Risk Management Plan will be amended to include a section pertaining to water distribution management. Equipment may also need to be purchased to implement the plan. Upgrades will be undertaken to enable swabbing of mains during 2019-20. Additionally the air scouring and flushing program within the distribution system continues as per routine maintenance activities.
Improved oversight to operation and verification systems
The final stage of this project includes the roll out of a water quality database to manage operational and verification data. A water quality database will provide greater oversight of our systems.
