Corporate Experience with Water- and Demand-Related Analyses

Ventura River Water District (VRWD) Cost of Service and Rate Setting Study (2017)

This study involved application of customer-level data into WaterEcon and presenting various rate structure scenario options for VRWD staff and leadership to choose from to ensure future revenue and supply source stability. This study followed a review of VRWD’s existing, in-house cost of service analysis and rate structure model as well as preliminary application of WaterEcon using District-specific data from previously completed studies and regional proxies from comparable purveyors.

Moulton Niguel Water District (MNWD) Cost of Service Peer Review (2017)

This analysis included a report describing a long-range financial plan, review of rate design, and cost of service analysis for three separate water systems—potable, recycled, and waste water. Additionally, we supported MNWD staff in presenting and explaining recommendations at the board of directors’ meetings.

Carpinteria Valley Water District (CVWD) Cost of Service and Rate Setting Study (2016)

This analysis involved application of customer-level data into WaterEcon and presenting various rate structure scenario options for CVWD staff and leadership to choose from to ensure future revenue and supply source stability. Rate options presented to CVWD were aimed to minimize rate shock on the District’s large agricultural contingent (and customer base in general) to the extent allowable by best utility business practices and local and state legal mandates. This study followed a review of CVWD’s existing, in-house cost of service analysis and rate structure model as well as preliminary application of WaterEcon using District-specific data from previously completed studies and regional proxies from comparable purveyors.

Los Angeles Department of Water and Power (LADWP) Data Collection and Water Rate Analysis for Natural Resource Defense Council (NRDC) (2015)

Using our in-house water rate model, WaterEcon, we conducted a series of sensitivity and scenario analyses on over 600,000 accounts to design candidate water rate structures for suitability in meeting NRDC’s conservation goals while maintaining District financial stability. Additionally, we assisted NRDC in presenting and explaining recommended rate proposals to LADWP as required.

West Basin Municipal Water District Irrigation Efficiency Program Analysis (2015)

This study provides a summary report and analysis of the water savings resulting from a conservation program offered to local residents that provided free landscape surveys and free installation of high-efficiency sprinkler nozzles. We worked with the agency to obtain historical customer billing records for those that participated in the program as well as customers that did not. Since West Basin is a wholesaler, this amounts to working with datasets from each of its retailers. Separate analyses were completed for single-family, commercial and multi-family customer classes.
