MINUTES OF THE
YORBA LINDA WATER DISTRICT
PLANNING-ENGINEERING-OPERATIONS COMMITTEE MEETING
August 21, 2008
A meeting of the Planning-Engineering-Operations Committee was called to order by
Committee Chair William R. Mills on Thursday, August 21 at 4:00 p.m. The meeting was
held at the District Administrative Office at 1717 E. Miraloma Ave, Placentia.
COMMITTEE:
Director William R. Mills, Chair
Director Paul R. Armstrong
STAFF:
Ken Vecchiarelli, Asst. General Manager
Lee Cory, Operations Manager
John DeCriscio, Chief Plant Operator
Leon de los Reyes, Water Quality Engineer
Steve Conklin, Consulting Engineer
INTRODUCTION OF VISITORS AND PUBLIC COMMENTS
None
ACTION ITEMS:
1. Consider Hydrogeologic Support Services for Siting, Drilling and Testing Two New
Groundwater Wells. Mr. Vecchiarelli reported that three proposals were received
for hydrogeologic services for two proposed replacement wells. Engineering staff
individually performed an evaluation of each proposal using a numerical rating and
matrix system. After comparing their individual and combined evaluations, it was
the finding of staff that the top rated proposal and firm was Camp, Dresser &
McKee, Inc., and recommends executing a Professional Services Agreement with
them for $179,469.
A discussion followed concerning potential sites for the two new wells. Mr.
Vecchiarelli reported that there is ample room for an additional well at the Well No.
11 site, near Orange County Water District's (OCWD's) recharge basins. He also
noted that staff was considering the second well being located near Los Ninos
Park. Director Mills expressed concern with locating a new well that far north, and
suggested looking at well sites closer to the Santa Ana River and to OCWD's
recharge basins for better production and water quality. He suggested looking at
sites near Warner Basin, and near Kraemer Basin and Miller Basin, the latter two
of which receive high-quality GWRS water for recharge. Director Mills also noted
that there are considerable benefits to consumers receiving lower TDS water such
as longer fixture life, and recalled that studies have been done by MWD and others
confirming this. Director Mills noted that this benefit would be an offset to the
added cost of constructing wells and pipelines further to the west.
2. Consider Professional Engineering Support Services for Well Optimization Study.
01 Mr. Vecchiarelli reported that the District continues to experience diminished
productivity from several of its wells due to age, physical characteristics and
configuration, exacerbated by the lower water pumping level in the groundwater
basin. In response staff is recommending proceding with a well optimization study
in the continuing effort to maximize the productivity of the wells. Mr. Vecchiarelli
noted that the firm Camp, Dresser & McKee (CDM) was retained by the District in
2005 to perform a wellfield analysis, and did a very good job. He reported that
CDM was asked to provide a proposal for the wellfield optimization study and that
they responded with a well-presented proposal, offering the same experienced
project manager who led the study in 2005. Based on these factors and the need
to proceed quickly to find means to mitigate the pumping concerns, staff
recommends moving forward with this study for a fee of $54,390.
DISCUSSION ITEMS:
3. Purchase Order for Emergency Repairs to Well No. 11. Mr. Vecchiarelli reported
that Well No. 11 is down for repairs. Mr. DeCriscio described the well condition,
noting the continuing problem with sand and gravel getting in the pump causing
wear and the ultimate need for repair. He noted that work will be completed shortly
and the well returned to service. The Committee members inquired about
improvement or changes staff was including in these repairs to alleviate the
problem from continuing. The Committee discussed these matters further.
4. Proposed Action Plan Responding to OC Grand Jury Report. Mr. Vecchiarelli
reported that the required response to the Grand Jury Report was completed and
mailed. Copies of the response will be in the Board's mail packet included with the
August 28th Board Meeting agenda. Director Armstrong asked for a copy of the
Grand Jury Report and Mr. Vecchiarelli said that he will provide a hard copy.
5. Status Report on Capital Improvement Projects in Progress. Mr. Vecchiarelli
reported that a copy of the monthly construction progress report for July 2008 for
the Highland Reservoir Replacement Project is included for the Committee's
review and information. Staff discussed Mr. Conklin's role in assisting with the CIP
Program management and that future updates would be prepared under his
supervision.
ADJOURNMENT:
The Committee adjourned at 5:05 p.m. The next regularly scheduled Planning-
Engineering-Operations Committee will be held September 4, 2008 at 4:00 p.m.
