Response to Grand Jury Report Form
Report Title: Will there be water after an Earthquake
Report Date: Not dated but delivered June 14, 2018 (SIC) Rec'd 6/14/19
Response By: Title: Mayor Teressa Barrett and
Title: CitManager Pegg�Flnn
Agency/Department Name: City of Petaluma
FINDINGS:
We agree with the findings numbered: F1, F2, F3, F4, F5, F6, F7, , F9, F10, F11
We disagree wholly or partially with the findings numbered: F8
F8 Because operating pressures must be maintained throughout the system, water
contractors have limited ability to curtail water uses without compromising availability of water
for critical applications such as fire suppression and hospital use.
Petaluma's Response:
Finding (178) is disputed because the City has the power to impose its water shortage contingency
plan during a water supply curtailment such as might occur during the after -math of an
earthquake. Under the Plan, the City would likely declare a third level emergency in which all
unnecessary water use (i.e. outdoor use, washing, etc.) would be prohibited and if a customer did
not comply, their water service would ultimately be shut off. It should be pointed out that by
shutting off a customer's domestic water supply, they would still have access to fire flows from
nearby fire hydrants, and if they do have an in -building fire sprinkler system, it is fed by a
separate fire service line that would not be affected if the domestic water service were to be shut
off for non-compliance with the drought restrictions.
RECOMMENDATIONS:
Recommendations numbered: RI, R2, R3, R4, and R6 are directed to Sonoma Water. R5 is the
sole recommendation directed to the City of Petaluma.
RS Water contractors study options for making local systems more adaptable under
emergency conditions — such as dedicated supply loops, digitally monitored metering, or
automatic shut -down valves, by December 31, 2019.
Petaluma's Response:
Recommendation #5 has not yet been implemented but will be implemented in the future. Key
regional elements will be implemented by Spring 2020. The City of Petaluma is continuously
L,
evaluating operational functions to add resilience and make the system less vulnerable. The City
is currently updating a vulnerability assessment and Gap study in resilience and operation
activities. The City of Petaluma is evaluating SCADA upgrades and performing automatic valve
replacements. These upgrades are anticipated to be completed by the end of 2020. The City will
have two booster pump stations and valves replaced in early 2020. The City has recently
upgraded storage facilities and has CIP projects for upgrades to all the reservoirs in the system.
Two reservoir upgrades for seismic and coatings are scheduled to be completed in 2021 with the
remaining by the end of 2023. A well siting study is currently underway, and an additional well
is scheduled for completion by mid -2021.
Local System Integration with Regional Wholesaler
The City of Petaluma fully supports the Grand Jury's recommendation to study options for
making our local public water supply system more adaptable for emergency conditions.
Although the water systems of Sonoma Water and its retail customers are inter -connected,
integration improvements are possible, especially in times of water shortage. By leveraging the
collective water resources and infrastructure of Sonoma Water and its nine retail customers, there
could be opportunities to improve water supply reliability and resiliency through better
integrated water resources planning and management.
To this end, the City of Petaluma and the eight other retail water contractors are funding a
Regional Water Supply Reliability Study (Study) coordinated by Sonoma Water. The Study was
initiated in February of this year when Sonoma Water engaged the services of Jacobs
Engineering Group to evaluate strategies and water supply projects to improve integrated water
resources management and make the service area more resilient to potential short term (e.g.,
earthquakes) and long-term (e.g. sustained drought) water shortages.
This Study will identify opportunities to enhance coordination and partnerships between the City
of Petaluma, Sonoma Water and the eight other water contractors for improved regional
integrated water supply emergency planning.
It is anticipated that this work will be completed by Spring 2020.
Local System Resiliency
In addition to purchasing wholesale water from Sonoma Water, the City of Petaluma has local
water supplies that are used to meet the demands of our customers. Based on State Water
Resources Control Board inspection documents, the City of Petaluma can produce a sustained
capacity of 50 gal/per person/per day, which means that the City should have enough emergency
water supply to meet the minimum water demand for sanitary purposes, such as drinking,
cooking and sanitation. The production of water from local sources is based on running wells
with one standby reserved.
Recommendation numbered: n/a has not yet been implemented but will be implemented in
the future.
Recommendations numbered: n/a require further analysis.
Recommendations numbered: n/a will not be implemented because they are not warranted or
are not reasonable.
