Lake Don Pedro History
• The water system was constructed in 1968
by Boise Cascade and governed by PacificCascade.
• In 1975, it transferred its interests to Sierra
Highlands Water Company.
• In 1980, it became a Special District for the
purpose of providing water services to the
community.
What is a Special District?
A special district is a separate local
government that delivers a public service to a
geographically limited area.
Special districts have four distinguishing
characteristics:
•
•
•
•
Are a form of government
Have a governing board
Provide services and facilities
Have defined boundaries
We are an Enterprise
• We are financially supported entirely by the
property owners within the District, we must
receive enough revenue to cover the expenses
to operate, maintain and expand the water
system.
• This is accomplished by continuously
reviewing expenses and ensuring cost
effective measures are in place to provide
water at the most reasonable price possible.

What are Some of the Top Issues Facing the
District?
• Insure compliance with E.P.A - Safe Drinking
Water Act
• Insure compliance with CDPH - state regulations
• Replacement of an Aging Infrastructure
• Deferred maintenance of Plant and Distribution
System equipment
• Drought conditions- low lake levels and the need
of a standby well
• Vulnerability Assessment- securing our assets
What Must be Done to Meet These
Challenges?
• Review the Capital Improvement Plan
• Source Waters
•
•
Surface water- ensure sufficient availability with a new barge and float
pump
Ground Water- ensure sufficient availability by testing/maintaining
Ranchito Well, look into constructing a second well for standby purposes
• Treatment Plant
•
Replace aged & broken plant equipment, upgrade antiquated HyperTac system,
upgrade SCADA and telemetry equipment
• Storage Tank Facilities
• Install fencing and gates to improve our security and reduce vulnerability to
theft and vandalism
• Infrastructure
•
Distribution system is over 40 years old. Need to be aggressive with water main and service
line replacements
• Insure CIP is Consistent with our Financial
Base
What About Future Goals?
•
•
•
•
•
CSD Subdivision Build-out
OPU Service
Golf Course
• Irrigation Water
Perform Services for Other Agencies
• Back Flow Testing
• Cross-Connection Surveys
• Laboratory Testing
Assume Other Services
• Trash
• Waste Water Treatment
• Horse Trails
• Etc…
First We Must Focus On the CSD’s
Immediate Goals/Challenges
• According To Stephen Covey, author of The 7
Habits of Highly Effective People, he mentions
that “in order to be effective with success, we
must work out of quadrants 1 and 2”.
• Filters of Importance
• Quadrant 1-urgent, crises, & deadlines
• Quadrant 2-maximizing current opportunities
Knowing is not enough, we must
apply. Willing is not enough, we
must do.
