Davao City moves to fixed network leakage monitoring

Installation of 320 Ovarro remote correlating loggers has taken place in Davao City in the Philippines, with a major leak detected just days later. The volume of water saved means a large-scale project to construct a new production well can be put on hold.

Davao is the largest city on the island of Mindanao and the third largest in the Philippines. With a rapidly increasing population, the city is considered one of the country’s fastest economic growth areas.

The population’s water supply is managed by Davao City Water District (DCWD), which has been challenged to reduce non-revenue water (NRW) losses by 1% per annum until it reaches a target of 20% NRW. Groundwater has historically been the city’s main source of water, but increasing pressures deriving from population growth and urbanisation means there is a need to limit abstraction and make supplies more sustainable.

For utilities like DCWD, reducing demand for water by cutting NRW is a key part of long-term supply planning. The district has invested in advanced correlating noise loggers from Ovarro’s Enigma range – 260 of the Enigma3m model and 60 of the Enigma3HyQ...
