Water utilities capitalise on hydraulic modelling to minimise totex, reduce risk, and mitigate water loss
Water utilities are faced with meeting a myriad of challenges ranging from disaster preparedness to environmental conservation to driving down total
expenditures (TOTEX), at the same time as they are expected to improve service. Three examples from the 2017 Be Inspired Awards nominations
demonstrate the key role hydraulic modeling applications play in achieving water utilities goals.
Manila Water is a water utility concessionaire in the Philippines that provides water and wastewater services for 24 cities and municipalities and operates more than 100 facilities
serving 6 million customers both in water distribution and wastewater
treatment. The Philippines sits on the Paciic Ring of Fire where earthquakes and volcanic eruptions frequently occur. Metro Manila falls victim to this circumstance, being geographically transected by several fault systems, including the dangerous West Valley Fault System. The Philippines is also ravaged by an average of 20 typhoons per year.
To address the great level of risk,
Manila Water conducted a Resiliency and Business Interruption (RBI) study to determine the systems and facilities that are most vulnerable in the event of such natural disasters. The study indicated that signiicant damages amounting to approximately USD 520 million in water infrastructure is inevitable. Consequently, the Natural Calamity Risk Resiliency and Mitigation Master Plan was developed in collaboration with National Disaster Risk Reduction and Management Council (NDRRMC) and Local Government Units (LGU). The NDRRMC and LGU provided the emergency response plan as well as locations of evacuation sites that will be used in the event of a catastrophe.
