Technological Database Increases Utility Efficiency
Region North of Manila, Philippines (Subic Water & Sewerage Co. service area)


Subicwater is a private water utility located 150 km northwest of Manila, serving 40,000 customers through a 370 km pipe network.


For more than a decade Subicwater was uncertain of how to best establish a reliable Geographic Information System (GIS).


Project Goal

After detailed discussions with utility management, Subicwater contracted Miya to build a Geographical Information System (GIS) to access business data, integrate work orders, find customer information an prepare reports. Subicwater also commissioned a Hydraulic Model of its distribution network to simulate operation of key elements to better identify anomalies and, most importantly, optimize modification designs for network improvements.


Project Scope

The project included the following elements:


  • Procurement and preparation of hardware and software GIS components
  • Customer census and geolocation
  • GPS survey and data acquisition of pipe routes and condition assessment
  • Data entry (digitization) of all network components
  • Hands-on training of Subicwater future GIS operators
  • Hydraulic model data acquisition
  • Measurement campaign for flow and pressures
  • Model calibration and field-checks for anomalies



The Miya project team consists of around 20 managers, engineers and field staff, working with the Subicwater team as well.

GIS was completed in mid-2014 and the hydraulic model is in its final stages.
