City of Santa Cruz Selects CapPlan Water

Leading Risk-Based Water Infrastructure Capital Planning Solution to Help Optimize Rehabilitation and Renewal Spending

Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced that the City of Santa Cruz Water Department, California, has selected Innovyze CapPlan Water as its drinking water infrastructure management and risk assessment solution. The purchase equips the City with a full range of high-performance asset integrity modeling and condition assessment capabilities to help strengthen and optimize its water infrastructure and keep it operating efficiently well into the future.

As the largest water agency in Santa Cruz County, the City Water Department has 24,300 connections, serving 90,000 customers. In addition to the City of Santa Cruz, it also serves the City of Capitola, the University of California at Santa Cruz and the unincorporated county areas of Carbonera Estates, Live Oak, the North Coast, Rolling Woods and Santa Cruz Gardens. The City's distribution system contains some 300 miles of pipeline.

" CapPlan Water gives us the powerful asset condition assessment and integrity management tools we need to help us optimize rehabilitation and renewal planning for our water system," said Doug Valby, P.E., Associate Civil Engineer for Santa Cruz Water Department. "The software will help us refine our capital improvement plan to provide maximum benefit for the lowest cost and continue to best serve our customers."

CapPlan Water changes the way water utilities plan the relative phasing of system improvements by allowing them to assess both the probability (likelihood) and consequence of failure for each asset. Assets that affect system operation will normally rate high on the consequence scale, while assets in poor condition will have a high probability of failure.

Probability (likelihood) of failure is determined based on the pipe's physical condition (structural integrity, age, material, roughness factor, leakage/break/defect history) and location (proximity to a seismic fault or construction zone) as well as its hydraulic performance characteristics (head loss, pressure, velocity). Consequence of failure draws on data such as water outages (schools, hospitals, critical care facilities); low- and no-water conditions; reduced fire protection capabilities; flooding, including structural damage and impacts of chlorinated water in natural waterways; degradation of water quality; and other factors.

CapPlan Water calculates the risk of each asset linearly (consequence score multiplied by probability score), using either a bi-directional distribution matrix or a more complex multi-criterion classification. This choice of calculation methods gives water utilities unprecedented flexibility in defining risk based on virtually any combination of supporting data.
