Planning is currently underway for a major sewerage upgrade in the southern end of Bacchus Marsh. The project also includes a section of water main to bolster the water supply in the Parwan area. The new infrastructure will cater for population growth in Maddingley to the west and the area south of Grant Street.
The project may be delivered as separate contracts.
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 may 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 1,300 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. 1km of 750mm diameter gravity sewer pipe will be constructed beside the existing sewer main, which was built in 1975 and is now nearing capacity.
