DAWACO flushed several pipelines in Son Tra district with monitoring and asssistance by 2 Manila Water experts and realized that additional infrastructure works were required for effective flushing. Manila Water identified the need for DAWACO to install additional blow-off points and valves to enable appropriate flushing and also determined that selected pipelines had to be replaced due to heavy debris accumulation. DAWACO is fixing selected pipes in the district and will continue flushing in priority areas to further check effectiveness. Manila Water will provide another round of monitoring following network improvements.
