Western Water has commenced planning for the construction of a 13.5km recycled water pipeline, 600mm diameter, between the Bacchus Marsh and Melton recycled water plants.
This is a new pipeline that will enable the transfer of excess recycled water between both plants. It traverses through mainly private land and includes a crossing at the Werribee River. A pump station will also be constructed at each end of the pipeline—at Bacchus Marsh RWP (approx. 85 L/s) and Melton RWP (400 L/s ).
The project will be split into separate contracts for delivery.
Western Water has begun planning to upgrade the storage capacity of the plant’s recycled water ponds by an additional 1,000 megalitres. The pond’s internal dimensions are approximately 400m x 400m and 10m high. It is likely to be clay lined and connected to a new pump station via one 900mm underground pipe.
Western Water is planning for the construction of a duplicate sewer that will transfer sewage from the corner of Powlett and Brook Street to the Sunbury Recycled Water Plant on Harker Street. 1.3km of 750mm diameter gravity sewer pipe will be constructed beside the existing sewer main, which was built in 1975 and is now nearing capacity.
Planning is under way for a new water pipe from ‘Bald Hill’ in Sunbury to development land in Diggers Rest. The project involves the laying of 600mm pipe in the road reserve along Moore Road, Sunbury, and a 375mm pipe from Moore Road to land just west of Bloomdale Estate. Work also involves boring underneath the Calder Freeway.
This project involves the upgrade of the Merrimu Water Filtration Plant’s existing system with a sodium fluoridation system. The project will be delivered as a design and construct contract.
