Seasonal Demand ManagementThis measure is defined by DOH as “implementing measures aimed at controlling peakseasonal demand.” Bellevue’s conservation pricing and landscaping management measuresdescribed above, are aimed directly at controlling peak seasonal demand.Recycling/ReuseThis measure is defined by DOH as “examining opportunities for water reuse and recyclingas an approach to providing additional water.”Cascade’s 2005 Transmission and Supply Plan analyzed reclaimed water opportunities forBellevue. Sources of reclaimed water include several King County wastewater treatmentfacilities: the south treatment plant, the future Brightwater treatment plant, and potentiallyother satellite facilities. Bellevue has no specific plans for water reuse due to the highlydeveloped nature of its service area. That situation makes provision of reclaimed water toexisting customers costly. Minimal opportunities will likely be available with regard to newdevelopment for which reclaimed water application is feasible. However, Bellevue hasidentified potential application sites in the irrigable areas, as shown in Table 5-4.Table 5-4Existing Sites with Potential for Reclaimed Water Application (1)Customer2003 TotalConsumption(ccf) (2)2003 TotalConsumption(gal) (3)2003 AverageDay Demand(gpd) (4)2003 PeakSeasonDemand(gpd) (5)Bellevue Community College 4,571 3,419,108 9,367 28,025Bentall Capital/Five Newport 10,040 7,509,920 20,575 61,557Foothill Commons Apts. 4,062 3,038,376 8,324 24,905Double Tree Inn 5,251 3,927,748 10,761 32,195Boeing Computer Services 5,145 3,848,460 10,544 31,545Central Park East Apts. 5,332 3,988,336 10,927 32,691Colony Woods Apts. 6,223 4,654,804 12,753 38,154Overlook at Lakemont 4,023 3,009,204 8,244 24,666Tam O’Shanter Golf Course 10,066 7,529,368 20,628 61,716Total 54,713 40,925,324 112,123 335,454NA = Not Applicable1.

The followingassumptions are made:Irrigation sites - Peak season use only. Peak season assumed to be 122 days (4 months) long.Industrial sites - Annual use divided by 365 days (full year).5-13
The Bellevue Convention Center Authority operates a pulp-extractor food waste system.The system reduces the facility’s water consumption by recycling garbage disposal rinsewater instead of using a flow through system, saving approximately 1 million gallons peryear. The system serves as a demonstration project for other such facilities, and led to theinstallation of another system by the Bellevue Public Schools in their central school lunchkitchen facility at Tyee Middle School.HISTORICAL CONSERVATION SAVINGSThe conservation savings Bellevue has achieved through 2004 are shown in Table 5-5. Thetable shows demand with and without conservation for various categories includingBellevue’s single family, multifamily, and commercial customer categories. Themethodology for calculating these numbers is described below and differs betweenresidential and commercial categories.The main steps to determine the conservation savings for the single family and multifamilysectors shown in Table 5-5 are as follows:1. “Number of Housing Units” and “Number of Accounts” in the year of interest (rows2-3) are obtained from the billing system. The numbers are 33,912 housing units forsingle family and 24,206 housing units for multifamily.2. “Water Use Per Housing Unit” and “Water Use Per Account” in the baseline period(rows 5-6) are calculated from data from the billing system. The baseline period of1986-1990 was chosen for three reasons. First, DOH suggests beginning calculatingdemand reductions in 1991, which implies using a baseline period prior to 1991.Second, using multiple years helps adjust for weather and other factors that maymake a single year unrepresentative; therefore extending back several years before1990 is reasonable. Third, this was the five highest-use years in the City’s history.The results per housing units are 283 gpd for single family and 152 gpd formultifamily.3. “Water Use Per Housing Unit” and “Water Use Per Account” in the three yearaverage (rows 8-9) are calculated from data from the billing system. A three yearaverage is used to correct for weather and other factors that may make the most recentyear, or any single year, unrepresentative. The results per housing unit are 240 gpdfor single family and 114 gpd for multifamily.4. “Normalized Demand Without Conservation” (row 11) is calculated by multiplyingthe “Number of Housing Units” in the year of interest (row 2) by the “Water Use PerHousing Unit” in the baseline period (row 5). The results are 9,597,096 gpd forsingle family and 3,679,312 gpd for multifamily.5. “Normalized Demand With Conservation” (row 12) is calculated by multiplying the“Number of Housing Units” in the year of interest (row 2) by the “Water Use PerHousing Unit” in the three year average (row 8). The results are 8,138,880 gpd forsingle family and 2,759,484 gpd for multifamily.5-14
