Discussion of the Water SCADA
Replacement Project
May 2, 2012
Background / History
• SCADA systems were built in the early 1990's
— Three systems include the District's main area, Glenshire,
and Donner Lake
— Systems normally last 6 to 10 years
— Current systems are not expandable and cannot interact with
each other
— Do not meet current industry standards
• In July 2009, the Board awarded a contract to Carollo
Systems for engineering services
— Phase 1 dealt with collection of system information and
evaluation
— Phase 2 involved design, specifications and cost estimates

New Information
• Carollo Systems has compiled a Technical Memorandum
(TM) with the results of Phase 1 and 2:
— Why the District should upgrade
— General and basic SCADA system requirements
— Network communication design
— Integrated energy management features
— Remote terminal unit (RTU) design
— Specifications for bidding of system components
— Work breakdown structure of construction and
implementation of Phase 3
— Engineer's cost estimate for Phase 3

New Information (cont.)
• Staff has reviewed the TM and recommends the following
proposal
— Dividing Phase 3 into 4 parts
— Performing implementation services of Phase 3 with in-house
labor and an outside panel fabricator
• Dividing Phase 3 into 4 parts enables:
— Ability to spread total cost over time
— Flexibility of development
— Increase project control
— Significant cost savings of $670,000 from Carollo estimate

New Information (cont.)
• Time line for completion of Phase 3A
— Issue RFB for 10 RTUs Summer 2012
— Issue RFP for radios and communication network Summer
2012
— Procurement of hardware and software Summer 2012
— Programming would begin Summer 2012
— Installation would begin Fall 2012
— Completion of Phase 3A Summer 2013
