Tedagua and Drace Medioambiente win two new contracts in Australia

The ACS Group companies Tedagua and Drace Medioambiente have been awarded contracts, through the Group's Australian subsidiary TEDRA Australia Pty Ltd., for the construction of the wastewater reuse plant of the WWTP at Werribee, to the west of Melbourne, amounting to AU $ 18.9 million, and the ancillary facilities amounting to AU $ 22.7 million (33.7 million euros at current exchange rates). Both contracts are for the design, construction, operation and maintenance of the facility for five years.

In the first phase the plant will be equipped with three pressurised membrane and hollow fibre ultrafiltration (2 +1) lines and two reverse osmosis lines with a total reclaimed water production capacity of 6,000 m3/day. In the second phase, scheduled for the second year of operation, production capacity will rise to 9,000 m3/day and finally to 15,000 m3/day after five years. The plant will be fully automated with online instrumentation and Scada system for computer control of the entire facility. Chemical product storage will include tanks for hydrochloric acid, caustic soda, dispersant, sodium hydrochloride, citric acid, coagulant, lime and carbon dioxide.

The ancillary facilities include an 8,300 m3 capacity feedwater tank, a 21,000 m3 product water tank and a pumping station with three 180 l/s pumps.

This award comes a year after commissioning the reuse plant for the Altona WWTP, also built and currently operated by TEDRA. The Altona plant and the new Werribee project are owned by City West Water, the body responsible for water management in Melbourne.

The success of TEDRA in obtaining the new Werribee contracts reflects the level of satisfaction of City West Water with the professional standard of TEDRA as EPC contractor for water treatment plants in Australia.
