Veolia Water can provides comprehensive maintenance programs for water and wastewater networks, involving emergency and planned repairs, cleaning sewer mains and water storage tanks, cathodic protection, mains flushing, detecting leaks, maintaining mechanical and electrical assets, and monitoring network performance.
The company's expertise in network optimisation has delivered excellent outcomes:
- Adelaide, South Australia - Throughout the 15.5 year contract, Veolia Water's subsidiary, United Water collected more than 6,000 water samples from 130 customer taps throughout the Adelaide metropolitan area anually. United Water also performed more than 17,000 tests to meet key performance indicators of colour, turbidity, pH, coliform bacteria, E.coli, fluoride, manganese, chlorine, iron and soluble aluminium. By optimising network performance, United Water lifted the rate of tap samples free from coliforms from 90 percent to 98 percent.
- Papakura, New Zealand - Since 1997, Veolia Water has improved the water quality grading (as assessed by the Ministry of Health) in Papakura's pipe network from a B grade or lower to an A grading. Combined with an A grading for water treatment, Papakura residents are now consistently receiving water of the highest quality.
