Geospatial Capital Investment Planning (GCIP)

New Jersey American Water (NJAW) has an established tabular Capital Investment Planning (CIP) methodology of analyzing system & regional infrastructure health. This method of reporting provides a valuable and defendable framework to guide, record, and repeat the high level decision making process of allocating resources to rehabilitate or replace aging infrastructure. One limitation of the current CIP workflow, however, is its high-level resolution. To formalize local water main prioritization into a scientifically defendable process, NJAW developed several GIS/CIP models, collectively known as the GCIP Toolset:

A) Repair Rate per segment
B) Percent life spent per segment
C) Quality, Distance to & Density of complaints per segment
D) Critical Points, Distance to Hospitals, Schools, Major Meters
E) Fire Flow
F) Comprehensive, A user defined weighted overlay of all models.

Special Fields:
Is Critical? Many Customers Affected in Outage
Is Bottleneck? Velocity too high in fire flow
