Description:
This is a multi-year project to locate and construct multiple groundwater wells to provide a backup water supply in the event of a natural disaster or other event that disrupts the City's water supply from Sonoma Water.
Current Activity:
This is a continous project estimated to be active until 2029.
Request for Statement of Qualifications:
The City of Santa Rosa’s Capital Projects Engineering Division is soliciting Statements of Qualifications (SOQ) from consulting firms for emergency groundwater supply investigation services. These services would be supplied under a Master Professional Services Agreement (MPSA) and are anticipated to be ongoing for multiple years. Specific Project Work Orders will be issued for the work to be performed under the MPSA.
The complete Request for SOQ is available under Correspondence on the lower left side of this web page. Statement of Qualifications must be submitted to Joyce Brandvold, Administrative Technician, not later than March 5, 2014, 4:00 p.m., at the Transportation and Public Works Department, 69 Stony Circle, Santa Rosa 95401.
BACKGROUND
In late 2003, the City developed an exploratory groundwater program to study the City’s groundwater sub-basins, establish a more thorough understanding of the hydrogeologic conditions underlying the City, and investigate and evaluate potential future emergency well sites within the City’s Urban Growth Boundary. To date, eight test borings (test wells) have been installed and tested and are being monitored by the City. This exploratory program will continue to assist in identifying locations for new emergency wells in the City.
The City adopted a Groundwater Master Plan in September 2013 that included several recommended policies and projects relevant to this Request for SOQ:
• Providing and maintaining emergency groundwater pumping capacity of 12.7 million gallons per day (mgd) to meet existing and future health and safety demands should the City’s other water supplies become restricted or be shut down due to an emergency. The City‘s current emergency groundwater supply is about 4.3 mgd. The City’s need for additional emergency groundwater pumping capacity is about 8.4 mgd.
• Continuing the City’s Emergency Test Well Siting Program
• Evaluating the feasibility of Aquifer Storage and Recovery (ASR) in localized areas of the City to meet localized needs
• Constructing four emergency wells (two in Central City Master Zone, one in the vicinity of Martha and Slater test well sites to serve Central City Master Zone, and one in Oakmont/S-12 Master Zone) within the next 2 to 3 years.
