OPERATIONS REPORT MARCH 2016
The General Manager/CEO provided the Committee with an overview of the structure
and the differences of an Ad-Hoc Committee and a Standing Committee; he stated that
the committee process provides the opportunity to conduct additional analysis prior to
Board consideration.
The Operations Manager presented the Operations and Maintenance Report for March
2016 explaining the activities conducted over the course of the month. The General
Manager/CEO asked that the charts presented be converted to a Million Gallon (MG)
measurements for easier understanding.
ENGINEERING DEPARTMENT UPDATES
The Assistant General Manager provided an Engineering Department update to the
committee. He also discussed the Patton State Hospital project including maintenance,
cleaning, inventory, and inspection of the sewer mains.
2
Minutes 4/25/2016 bvm
Staff discussed the following projects with the committee:
•The District received a $2,000,000 grant for The AMI (Advanced Metering
Infrastructure) project.
•Plant 134 Getaway Upgrade was reviewed. It was noted that the plant upgraded
its production capabilities from 4 million gallons per day to 8 million gallons per
day. To aid in this process, booster pumps were replaced and the distribution
main was upsized from an 8” to a 16” water main.
•Pumalo Street Water Main Replacement is scheduled to begin construction when
school is out this summer. After further review of the site, staff determined that
the line is too shallow and does not meet current standards. The District will
coordinate the movement of this line to ensure the replacement is within current
engineering standards.
•The North Fork Record of Survey was presented and discussed. Staff present in
the audience explained the significance of setting monuments to identify the
location of the pipeline. The pipeline will be made of ductile iron as that is the
current standard being used.
SET THE DAY AND TIME TO HOLD RECURRING COMMITTEE MEETINGS
The Committee discussed and established that they will meet May 23, 2016 and will
then proceed to meet on the fourth Monday of each month at 2:00 p.m. for the next
four months. The Committee will review the frequency of future meetings and consider
quarterly meetings at their September meeting.

STAFF REPORT
Agenda Item #2.
Meeting Date: May 23, 2016
Discussion Item
To: ENGINEERING AND OPERATIONS COMMITTEE Members
From: General Manager/CEO
Subject: Presentation of 2014 Water System Master Plan
RECOMMENDATION:
This is an information item only.
BACKGROUND / ANALYSIS:
In January 2014, the District completed a Water System Master Plan (WSMP) for the District’s existing water
facilities and future water demand projections. The projections were based on the adopted General Plans of
the City of Highland, City of San Bernardino and the County of San Bernardino, for the land areas within the
service area of the District. The work was completed by MWH, an international firm which was selected
through a competitive process. The Water System Master Plan identified deficiencies in the existing system as
well as the requirements to meet future demands in terms of new water supply resources, pipelines, pumping
stations and storage. Typically Master Plans are updated every five years which would imply that the District
would be ready for an update in 2018. Since there is a severe drought and mandatory conservation efforts are
underway, coupled with the District’s implementation of a major water supply groundwater recharge program
through the Sterling Natural Resource Center, it may be prudent for the District to include an update of the
WSMP in the FY 2017-2018 budget.
The purpose of this presentation is to give the Engineering Committee a comprehensive and detailed
assessment of the District’s facilities including any deficiencies in the existing system identified in the 2014
WSMP and Capital Improvement Program to remedy these deficiencies. The future Capital Improvement
Project needs will also be discussed. The presentation includes highlights of the proposed projects to serve
the upcoming large developments within the District’s service area. During the preparation of the WSMP,
Harmony Development funded a study through the District for MWH to evaluate the water conveyance and
other facilities required to serve their development. The results of that study will also be presented.
Since the completion of the WSMP, MWH also completed a detailed study of the Highland Hills Development
project. The results of that study (funded by the developer through the District) will also be presented.
AGENCY IDEALS AND ENDEAVORS:
Ideals and Endeavor I - Encourage Innovative Investments To Promote Sustainable Benefits
(A) - Develop projects and programs to ensure safe and reliable services
(B) - Manage and identify methods to conserve natural resources
(E) - Actively seek alternative supply resources
