Applications
Planning and Management Consultants, Ltd. (PMCL, now a subsidiary
of CDM) developed many custom applications of the IWR-MAIN software.
CDM maintains this experience in custom applications through the
staff in its Carbondale office.
Custom applications of IWR-MAIN (DOS versions)
- PHX-MAIN: Customized water demand models based on an analysis of customer billing records for the City of Phoenix, Arizona.
- SWF-MAIN: Customized water demand models based on an analysis
of utility data for all counties within the Southwest Florida Water
Management District.
- MWD-MAIN: Customized water demand models based on an analysis
of utility data for all member agencies of the Metropolitan Water
District of Southern California.
Custom applications of IWR-MAIN (Windows versions)
- ACT-ACF Comprehensive Study: Customized water demand models
based on an analysis of billing records from a sample of utilities
and industries in Alabama, Georgia and Florida. The software provided
water demand forecasts and conservation assessments for 112 counties
in the Alabama, Coosa, Tallapoosa and Apalachicola, Chattahoochee,
Flint River basins.
- City of San Diego: Water demand models developed for the
San Diego County Water Authority were incorporated into IWR-MAIN
for use by the City of San Diego in estimating water demands for
34 planning areas within the City.
- PRASA: Customized water demand models were developed for
the Commonwealth of Puerto Rico. Water demand forecasts were developed
for each county of Puerto Rico for the Puerto Rico Water and Sewer
Authority (PRASA).
Custom applications of Water Demand Forecast Models
- SDCWA: Customized water demand models were developed for
the San Diego County Water Authority from analysis of utility data
from each of the Authority’s member agencies. Water demand
forecasts are generated for each of the member agencies and included
estimated impact of future conservation.
- City of San Diego Water Department: Water demand models
developed for the San Diego County Water Authority were used in
estimating water demand by sector for 134 hydraulic pressure zones
within the City service area. The forecasts included water savings
estimated from planned conservation programs, and were used to assess
impact of potential climate change on future water demand.
- Miami-Dade Water and Sewer Department: Analysis of MDWASD
billing data provided water demand factors for single-family, multifamily,
and nonresidential water users within each of 1400 Traffic Analysis
Zones. Estimated conservation savings for each sector were also
included in the forecast and allocated to each TAZ. The water demand
forecast separates estimated non-revenue water losses into apparent,
real, and unbilled loss to separate the impact of conservation on
water losses.
- Central Puget Sound Water Suppliers’ Forum: A dynamic
model was developed for the Forum that provides regional water demand
forecasts at various geographic delineations. The dynamic features
of the model allow for scenario planning and sensitivity analysis,
including alternative demographic growth estimates, weather variables
reflective of global climate change, and adjustments to consumer
sensitivity to income and price of water. The model graphically
displays the dynamic water demand forecast results and scenario
comparisons.
