INNOVATION IN WATER, WASTEWATER, AND STORMWATER NETWORKS
In Istanbul, Turkey, the water, wastewater, and stormwater infrastructure totals
about 27,500 kilometers, with more than 500 facilities and 1. 3 million buildings.
Although ISKI’s infrastructure information system consisted of file server-based CAD data and linked attributes, its challenges included lack of data
synchronization among distributed servers and the inability to control access
and modification processes. Moreover, querying the whole system was difficult.
To overcome these constraints, ISKI built ISKABISpatial, a CAD-based GIS data
production, analysis, and reporting platform. Data management tools for water,
wastewater, and stormwater were programmed in MicroStation VBA, and
existing data was migrated into Oracle Spatial with MicroStation running on top.
All infrastructure data input and updates are now made via MicroStation, with
the data transferring directly into Oracle 11g. Since implementing ISKABISpatial,
ISKI has saved 70 to 90 percent of its asset management expenses.

Network Improvement Master Plan of Metro Manila East Zone
Manila, Philippines
Before Manila Water Company could expand coverage south of Metro Manila
and Rizal Provinces in the Philippines, the existing network in the central
distribution system needed improvement. The system is supplied by two major
transmission lines—one that is already overloaded and one that is not fully
utilized. The $450 million program will solve this imbalance as well as ensure
reliability in areas prone to breakages, water theft, and illegal connections.
The master plan was designed by creating a hydraulic simulation model of the
central distribution system using WaterGEMS. Through the model, network
reliability projects were conceptualized on a per-business-area basis to ensure
that they are consistent with the development plans of the local governments.
This process resulted in savings in both capital and operational expenditures.
