TasWater is the provider of water and sewerage services throughout Tasmania and is responsible for managing 76 drinking water systems with over 200,000 connections.
In 2010, the drinking water supply systems for the towns of Westbury, Hagley and Exton were not filtered and did not meet the Australian Drinking Water Guidelines for key health parameters. At the time of the project Westbury was the largest town in Tasmania to have unfiltered drinking water.
MJM Environmental was engaged by TasWater to assist the authority to procure the $5 million Westbury Water Treatment Plant (WTP).
The scope of works completed by MJM over a number of separate projects included the following:
- Bench Scale Jar Testing Investigation
- Treatment Options Assessment
- Development of WTP Process, Civil, Electrical and Control Design
- Prescriptive Design and Construct Contract Documentation
- Tender Assessment and Detailed Review
- Design and Construction Superintendent Representative and Technical Engineering Services
MJM Environmental worked closely with TasWater to deliver the following outcomes for the project:
- Select the most appropriate technology for the Westbury raw water supply
- Deliver Westbury WTP project on time and on budget
- Actively transfer knowledge to TasWater as it transitioned from Ben Lomond Water, which assisted the newly-formed organisation to efficient deliver its capital works program
