At a Glance

City & County of San Francisco monitor data from an expansive water distribution system spanning rural watersheds and urban service areas. Time-series data are continuously collected from sampling and SCADA systems. Water balance calculations, forecasts & reports inform decisions on water supply and drought.

Problem Addressed

More than 100 years of historical data regarding urban water distribution and source water was migrated from Access databases reaching their maximum capacities. An integrated and scalable database was needed to manage water resource information in the present and long into the future, meeting demand. The utility also desired to increase data access among its staff for quality assurance and control, analyses, reporting and process improvement.

San Francisco Public Utilities Commission used/is using Water Information System by KISTERS (WISKI) and web services to address this/these challenge(s).

Solution(s) Used

San Francisco implemented Water Information System by KISTERS (WISKI) to automatically archive, validate, calculate and report on continuously collected data from the field and SCADA systems within San Francisco's drinking water distribution system. A web solution enables internal staff members to access and review data, configure built-in forecast tools for water balance and demand, generate and distribute reports. In addition, a public web portal or the Hetch Hetchy Regional Water System Data Viewer publishes meteorological and operational data and reports to wholesale customers.

Outcomes

  1. Time savings with the automation of data retrieval and import from various data streams including external websites in addition to evaluation of data quality
  2. Increased confidence in decisions as surface water, reservoir levels, groundwater, precipitation, pump availability, and more variables of concern are combined for consideration
  3. Improved wholesale customer service as an open data web portal provides important updates about the water supply, transmission system, and deliveries from source waters
  4. Improved wholesale customer service as an open data web portal provides important updates about the water supply, transmission system, and deliveries from source waters

Something Unique

SFPUC and Turlock Irrigation District, an adjacent local governing agency, collaborate and exchange water data via web services to optimize reservoir operations and minimize potential flooding risks in the Don Pedro Water System.
