OVERFLOW RESPONSE WHEN DAMAGE HAS OCCURRED When, during a service call, it is found that a City sewer main has or is causing damage to private or public property, the first priority must be to remove the stoppage and stop the inflow of sewage onto the property. Where damage has occurred, the following steps should be taken after the stoppage is cleared: 1. Contact Utilities Division Superintendent and describe the conditions found, the extent of the damage. If unable to contact the Supervisor, call the Director of Operations Services. Summon other employees for assistance if necessary. 2. The Utilities Division Superintendent will notify the Director of Operations Services if there is damage or possible damages which may result in a major claim. 3. Do NOT acknowledge or discuss liability or responsibility for damages. Refer these questions to the Environmental Services Manager, Utilities Division Superintendent or the Director of Operations Services. 4. Where flooding has occurred on public properties (streets, parks, school grounds, creek beds, etc.) remove any visible signs of the flooding by containing, washing down with potable water, and vacuuming the areas affected. 5. Where damage to private property occurs, provide a copy of a "Claim Presented to the City of Pleasanton" form (Attachment A) 6. Record damages with a video camera recorder. The responder may also take still photographs, if deemed necessary. The responder will file a complete written report with the Environmental Compliance Supervisor, describing details of the service call, who responded, what was found, and what was done.The Environmental Services Manager shall investigate the report and manage the initial claims process. DOCUMENTATION OF A SPILL A. Provide accurate flow measurements and estimate duration of spill. It is extremely important to apply logic or a scientific approach when estimating Flow 1. If the flow is coming from a cleanout or a broken line, count the number of upstream connections and estimate the time that the flow has been occurring. Remember that the flow was probably flowing before it was noticed and reported. Each residence contributes between 160 and 200 gallons per day or about 8 gallons per hour/ (depending on the time of the day). Assuming no flow is going through the plug/break, multiply the number of residences by estimated gallons per hour times the number of hours. This gives you an approximate number of gallons. 27IPage
