COUNCIL COMMUNICATION
AGENDA TITLE: Adopt Resolution Authorizing City Manager to Enter into Contracts to
Purchase and/or Reactivate Replacement Granular Activated Carbon for
DBCP Treatment Systems at City Drinking Water Wells ($230,000)
MEETING DATE: April 20,2005
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council adopt a resolution authorizing the
City Manager to enter into contracts to purchase and/or reactivate
replacement Granular Activated Carbon (GAC) for DBCP treatment
systems at City drinking water wells.
BACKGROUND INFORMATION: The City of Lodi currently has six wells with treatment systems that
use GAC to remove dibromochloropropane (DBCP). The wells
must have this treatment in order to be used by the City water
system. Four systems are anticipated to require GAC replacement
during the 2004/05 and 2005/06 budget periods. The cost of replacing and/or reactivating GAC is
between $42,000 and $72,000 per well, totaling approximately $230,000 for four wells. The life of the
GAC in a treatment system has varied between 29 and 40 months. Currently, using innovative operating
strategies, three systems have had GAC on line for over 55 months and two systems for over 40 months.
When breakthrough of DBCP occurs, the treatment system must be taken off line and the spent GAC
replaced/reactivated. At this time, it cannot be exactly determined when breakthrough will occur in any of
the systems. Breakthrough could occur before July 1, 2005, or in the 2005/2006 fiscal year. The
treatment systems contain between 60,000 and 90,000 pounds of GAC each. Reactivation of the spent
carbon will allow the City to obtain applicable recycle credits.
For the two most recent replacements of GAC, the City has participated in GAC contracts taking
advantage of bid prices for larger water systems. GAC manufacturers/vendors have again expressed a
willingness to allow us to participate in such a contract. An informal bidding process will evaluate prices,
quality of GAC, reactivation credits, services provided, and availability.
FISCAL IMPACT: The funds for this project will be coming from the Water Utility Fund's DBCP
Operations and Maintenance account which is funded, in part, under the
terms of the DBCP settlement. The funds were budgeted in 2004105 and are
in the proposed 2005/06 budget.
FUNDING AVAILABLE: The $230,000 is budgete in the Water Utility Fund
