Water Shortage Contingency Plan THE CITY OF PLEASANTON. Patterson Pass Water Treatment Plant to continue operating during a power outage. If warranted by demand, Zone 7 would also operate their wells, which have either a dedicated generator in place (Mocho I well) or have the necessary hook -ups installed for connection to a portable generator. Zone 7's turnouts to the City receive gravity flow from the treatment plant clearwells, so a power outage would not impact transmission from the treatment plants to the City. The City can also operate its own wells during a power outage through the use of emergency generators located at its well sites. Additionally, the City could also receive water from emergency interties with DSRSD and Livermore when necessary. 4.5.3 Earthquake Water system infrastructure, including pump stations, storage tanks, and pipelines, can be damaged during a strong earthquake. The City's facilities, as well as Zone 7's facilities, have been constructed in accordance with the applicable building codes to minimize potential damage during an earthquake. Additionally, approximately 85 percent of the City's water infrastructure has been earthquake reinforced, and no area within the service area is solely dependent on non -earthquake reinforced infrastructure. The City has multiple turnouts from Zone 7, so If one is damaged during an earthquake, the City can use the remaining turnouts to continue receiving water supply from Zone 7. Furthermore, the pipelines were built in a looped arterial design to ensure there is more than one route for water flow. 5.0 COMMUNICATION PROTOCOLS In the event of a water shortage, the City must inform its customers, the general public and interested parties, and local, regional, and state entities. Communication protocols for foreseeable and unforeseeable events are provided in this section. In any event, timely and effective communication must occur for appropriate response to the event. Key City staff are provided cell phones, and all City staff are provided email accounts to communicate internally and externally. 5.1 Communication for Foreseeable Events Water shortage may be foreseeable when the City reviews Zone 7's Annual Sustainability Report and prepares its AWSDA, as described in Section 2.0. When the City determines the potential of a water shortage event, City Council may declare a water shortage emergency. For imminent events, the City Manager may declare a water shortage emergency. If a water shortage emergency is anticipated, City staff will coordinate interdepartmentally, with the region's water service providers, and with Alameda County for the possible proclamation of a local emergency. In a duly noticed meeting, the City Council will receive presentation of the current or predicted shortage as determined by the AWSDA. The City Council will determine if a water shortage emergency condition exists and the degree of the emergency, while considering the shortage response actions triggered or anticipated to be triggered by the shortage level. As necessary, the City Council will act on the water shortage emergency declaration, associated water shortage stage, and shortage response actions. 13 City of Pleasanton N-e80-60-20-04-wP-R-e80-2020uwMP Last Revised: 05-05-21
