Background The Residential Recycled Water Fill Station opened in October 2014 after a drought emergency was declared by the Governor, then in June 2015, mandatory water restrictions went into effect. The fill station continued to operate in 2016, although drought restrictions were far less than observed in 2015. Local water agencies lifted landscape watering restrictions, which, greatly reduced usage of the fill station. Hours and Days of Operation In 2016, the days and hours of operation were divided into two seasons. Winter hours of January through April and October through December followed the HHW facility schedule of Dam to 4prn (7 hours a day) Monday through Saturday. During summer hours, the fill station was operated 8arn to Spm Monday to Friday (110 hours a day), and Saturday and Sunday from 9arn to 4pm (7 hours a day), May through September. During the summer season, the fill station was open for four hours on the holidays of Memorial Day and Independence Day. The fill station was closed on Labor Day due to the decline in visits after drought restrictions had been reduced. The fill station was closed on all holidays celebrated during the winter season. The fill station was also closed on July 161h for Central San's 70th Anniversary and on August 17th for the employee appreciation celebration. Below is a comparison of the 2015 and 2015 hours and days of operation.

The reduction likely can be attributed to the increased rainfall in the winter, which in turn, resulted in reduced water restrictions by local water purveyors. There was also a considerable decrease in the number of new recycled water users being registered. A total of 180 new users were trained and registered in 2010, this is decrease of more than 75 percent over 2015's which had 2,155 registered users.

The 93 percent decline in interest is assumed to be due to the reduction or elimination of landscape irrigation restrictions. Many of the new users say they REEF Committee February 17, 2017 Meeting 2016 Residential Recycled Water Fill Station Summary Report Page 4of7 removed much of their landscape last year and want to continue conserving water by trying recycled water.

In 2016, 6,491 ,532 gallons of recycled water was taken by users. This is just over half of the 11,775,005 gallons taken in 2015. The average amount of water taken by each user (visit) increased from 212 gallons per visit in 2015, to 227 gallons in 2016. This increase can be attributed to the larger amount of 275 to 366-gallon "totes" being used.

A log was prepared to track the wait of users. As a result of the reduced interest in recycled water, the typical wait time was far below the 15 minute maximum, if there was a wait at all. The longest waits occurred when the fill station opened in the morning when there were more than seven cars in line. RESP committee February 17, 2017 Meeting 2015 Residential Recycled Water Fill Station Summary Report Page 6 of 7 Staff i n g During the winter season, one of the temporary staff were retained and trained in order to split time as needed at the fill station and in HHW. This was very effective in keeping both operations running efficiently and without impacting service at the HHW facility. During the summer season, a total of ten fill station temporary technicians were initially hired in order to meet the expected demands of the summer of 2015. When drought restrictions were reduced by the State and local water agencies, there was a considerable decrease in the anticipated fill station usage. Because of this, the number of temporary staff was reduced to meet the demand. For most of the summer season, 6-7 temporary staff were.used, primarily because the 7-day work week and extended hours. overtime was required for Senior HHW staff to oversee fill station technicians on Sundays and holidays. The cost to staff the fill station was approximately $115,000. By utilizing District-hired fill station technicians, we were able to reduce costs by more than 50 percent over using a temporary service to provide staff. Options for the Fill Station in 2017 In 2015, the fill station saw a major decrease in participation compared to 2015, primarily because landscape watering restrictions were lifted by water purveyors: So far in 2017, northern California reservoirs are full, but groundwater throughout the state remains in deficit. We are expecting participation in 2017 to be even less than 2015. The fill station is currently operating under a temporary drought response authorization from contra Costa County community Development Department (CCCCDD). In 2014, the HHW facilities' land use permit (LUP) was approved to be temporarily modified to allow the fill station to operate on the HHW facility grounds. At this time, it is uncertain if the governor will lift the drought designation in 2017. If it is lifted, staff will need to prepare a LUP modification request to continue to operate. If the drought is not lifted, we are assuming that we can continue to operate under the original authorization and will request clarification from CCCCDD about where our approval stands considering the current conditions. Here are four options to consider for the residential fill station in 2017, based on lower than 2016 participation: ■ option 1: open the fill station under the same operating hours as in 20 6. , Summer hours would run 7 days a week May through September. Winter hours Y g p would be the same as the HHW Facility, October through April. This will provide 64 hours a week of access to the fill station users. REEP Committee February 17, 2017 Meeting 2010 Residential Recycled Water Fill Station Summary Report Page 7 of 7 o cost: It is estimated that this option would cost approximately $70,000 a year to staff and operate with 3-4 fill station technicians. This will still require overtime for HHW staff on Sundays to oversee the fill station. * Qption 2: Klatch the fill station operating hours to HHW. The fill station can be operated during HHW facility hours, therefore operating six days a week (Monday through Saturday) will provide 42 hours a week of access to the fill station users. Since the fill station will operate six days a week, additional staff will be needed. Matching the HHW hours eliminates overtime required by HHW staff to oversee the fill station on Sundays. o cost: The estimated cost to operate under this option is $55,000 a year to staff and operate with 2-3 fill station technicians. • option 3: Match the fill station operating hours to HHW, but reduce operaggg days to five. The fill station can be operated during HHW facility hours, but be open five days a week (Monday, Tuesday, Thursday, Friday, and Saturday. Closed Wednesday and Sunday). This provides 35 hours a week of access to the fill station users, while reducing staffing down to one or possibly two fill station technicians. o Cost: The estimated cost to operate under this option is $25,000 a year to staff and operate with one fill station technician ($40,000 for two, if needed). No overtime by HHW staff will be needed. • option 4: Do not open the station. This may upset some users, as they have voiced concerns about their investment in equipment and have said they will want to continue to use recycled water even when not in a drought. o Cost: There would be no cost to close the station.
