City Council to adopt Resolution No. 2014-_, authorizing repairs to Well 16.
Well 16 is presently off-line following installation of treatment facilities, including new treatment media. The well’s water production capacity (1300 GPM) exceeds the design capacity of the media (900 GPM). Well 16 also has the highest concentration of arsenic in the City, approximately 4 times more than the other wells.
There is an urgent need to have Well 16 back on-line in the near future to meet the City’s water demands that will likely increase in the Spring and Summer.
Staff has proposed repairs to Well 16 at several Stakeholders’ Meetings that will address the need to adjust production towards meeting the 900 GPM design flow for the treatment media, and will investigate and likely reduce the arsenic concentration in the well and prolong the life of the media.
Staff evaluated existing well data and equipment in order to address the need to:
1. Adjust well output from 1300 GPM to 900 GPM
2. Reduce arsenic concentration
Staff established a multifaceted approach that will simultaneously address both issues in a very cost effective manner.
Since the well has by far the highest concentration of arsenic in the City and is the only well that draws water from the aquifer below the Corcoran Clay (below 300 feet), it is very likely that the higher arsenic producing strata are below 300′ of depth. This is also consistent with water quality trends in several neighboring areas.
In order to reduce the arsenic concentration, it is proposed that sampling and an analysis of each of the well’s water producing perforations be performed to identify where the highest concentrations are, followed by "blanking" those perforations. As a result, it is anticipated that the overall arsenic concentration will drop considerably, possibly to levels similar to those in other City wells. As a result of "blanking" these perforations, the total water production of the well will drop.
In order to adjust for the reduction in yield, it is proposed that the pumps impellers be trimmed to a target production not to exceed 900 GPM. This will, in turn, reduce power consumption, conserve energy, and lengthen equipment life.
Additionally, the lower arsenic concentration will lengthen the life of the treatment media proportionally.
The estimated construction cost to perform the strata sampling/analysis, "blanking" of perforations, trimming impellers, and removing/re-installing pump/motor is $50,000.00.
1. Resolution No. 2014-
RESOLUTION NO. 2014-
A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF LIVINGSTON APPROVING AN AGREEMENT WITH SHANNON PUMP FOR SAMPLING AND REPAIRS TO WELL 16, MAKING FINDINGS SUPPORTING THAT AWARD OF SUCH AGREEMENT IS EXEMPT FROM COMPETITIVE BIDDING REQUIREMENTS, AND AUTHORIZING THE
CITY MANAGER TO EXECUTE THE AGREEMENT
WHEREAS, there is a need to make certain repairs to well 16; and WHEREAS, the estimated cost for said repairs is $50,000.00; and
WHEREAS, bringing Well 16 back in production is required immediately to protect the public health safety and welfare by performing water strata sampling and analysis, isolating of perforations, and trimming of pump impellers; and
WHEREAS, work by the Contractor is also required immediately to protect the public health safety and welfare by permitting the City to continue meeting its water demands; and
WHEREAS, to protect the public health safety and welfare to the maximum extent City staff have recommended immediately contracting for sampling, analysis, and repairs to Well 16 needed to bring Well 16 back in production; and
WHEREAS, the City Council of the City of Livingston hereby finds as follows:
A. Competitive bidding of the sampling, analysis, and repairs necessary to bring Well 16 back in production would delay the ability of the City to provide adequate water supply as required by state regulations for meeting maximum day demands for existing water customers, and would thus jeopardize the public health, safety and welfare; and
B. Competitive bidding of the work necessary to place in production Well 16 would also delay the City’s ability to entitle development projects adding demand to the City’s water system, and to safely obtain for the City the services, housing, economic development and other benefits of such new development in the City, and therefore competitive bidding of such work would not produce an advantage for the public.
C. There is an urgent need to bring Well 16 in production as soon as possible in order to meet the City’s water demands that will likely increase in the Spring and Summer.
D. There is an urgent need to bring Well 16 in production to enable the City to move forward with the installation of wellhead treatment facilities at Well 13, which will require Well 13 to be off line for some time.
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Livingston as follows: Section 1. The above recitals are true and correct findings of the Livingston City Council.
Section 2. Award of a contract for the sampling, analysis, and repair work necessary to bring Well 16 back in production is exempt from California Public Contract Code competitive bidding requirements pursuant to the established common-law doctrine articulated in the case of Graydon v. Pasadena Redevelopment Agency (1980) 104 Cal.App. 3d 631.
Section 4. This Resolution shall take effect from and after the date of its adoption.
Section 5. Each portion of this resolution is severable. Should any portion of this resolution be adjudged to be invalid and unenforceable by a body of competent jurisdiction, then the remaining resolution portions shall be and continue in full force and effect, except as to those resolution portions that have been adjudged invalid. The City Council of the City of Livingston hereby declares that it would have adopted this resolution and each section, subsection, clause, sentence, phrase and other portion thereof, irrespective of the fact that one or more section, subsection, clause sentence, phrase or other portion may be held invalid or unconstitutional.
Passed and adopted this 18th day of February, 2014, by the following vote:
Rodrigo Espinoza, Mayor of the City of Livingston
I, hereby certify that the foregoing resolution was regularly introduced, passed and adopted at a Regular Meeting of the City Council of the City of Livingston this 18th day of February, 2014.
Antonio Silva, City Clerk of the City of Livingston
