KORTECH CONSULTING, INC. Page 2 of time has been required to analyze design alternatives and devise feasible solutions. The selected design alternative imposes additional implementation work for KorTech. 3. KorTech has been asked to act as the project manager through the launch date of January 2009, vs. June 30, 2008. 4. KorTech has been asked to provide ongoing maintenance, support, and project management through June 30, 2009. Scope of Work for Completion of Stage 11 W AP Stage 11 provides the following major enhancements to the Water Allocation Program: 1. It implements budget-based billing, where penalties may be imposed when water consumption exceeds allocation. Initially, and for the foreseeable future, budget-based billing will be implemented only for irrigation customers. 2. It replaces static evapotranspiration (ET) tables 1 with actual weather data from the California Irrigation Management Information System (CIMIS) as the basis of water allocation calculations. 3. With real-time weather-based water allocation calculations, WAP Stage 11 replaces the water allocation calculation engine in BMP5, supplying allocation data to BMPS through a web interface. Some immediate consequences of this are: 1. Single-family residential customers2, who currently see static allocation figures on their bills as information only, will see allocations based on weather data instead. 2. Irrigation customers2, whose bills prior to WAP Stage 11 do not reflect allocations, will be billed based on weather-based allocations. All irrigation accounts at a customer site will be billed as a single rolled-up billing account so that total consumption for all accounts at the site can be compared to the total irrigation allocation. W AP Stage 11 will also provide the following enhancements: 1. Allocation (and consumption) will be calculated for periods based on the dates that meters are read, vs. the actual billing cycle dates. Thus allocation periods do not necessarily align with billing periods or calendar periods. The start dates of allocation periods and consumption periods align, but allocation periods always end the day before the corresponding consumption period ends. This is because allocations are always calculated for a 24-hour day, so no day can be included in two allocation periods. 2. WAP allocation formulas will support functions for computing Net Irrigation Requirement (NIR) based on CIMIS weather data. The NIR can be calculated for any given day, and summed across an allocation period. 3. CIMIS data will be downloaded automatically every day. The weather station(s) that supply the data are controlled by WAP configuration parameters that can be easily changed. 4. PWS staff will have the opportunity to override CIMIS weather data during a brief window (a few days) between the download of the data and the generation of bills. If the 1 These ET tables represent historic averages that can be used to compute water allocations. 2 We use "single family residential customer" to mean a customer who is responsible for a site with at least one SF RESIDENTIAL meter. Similarly, an "irrigation customer" is a customer who is responsible for a site with at least one IRRIGATION meter.
