The plant, with primary and secondary treatment systems, is to have capacity for an average flow rate of up to 15,000 cubic metres a day (cm/d) and a two-hourly peaking factor. The required conveyance system will include a seven-kilometre gravity pipeline for the sewage, three kilometres of force main and a sewage pumping station. The tender also has several options, including a reuse storage facility of 500,000 cm/d and a distribution system for agricultural re-use, as well as an additional 35-kilometre gravity sewerage pipe. The selected contractor may also be required to carry out operation and maintenance training.
The tender for the project is expected to be issued by the end of the year, and an award is scheduled by next summer. Construction is forecast to take 24 months.
