Program Delivery Plan

SECTION 7. SUPERVISORY CONTROL AND DATA ACQUISITION (SCADA)
The schedule of the project delivery is based on this prioritization. The project delivery plan
involves design of the system components in three projects in 2010 and 2011. Construction
will then commence in 2011 and continue throughout the program duration. Table 7-1
shows the cost summary for the projects.
TABLE 7-1
SCADA Cost Summary
Item
North WWTP SCADA – construction $2,302,000
Collection System SCADA – construction $12,902,000
SCADA Operations Data/Control Center – construction $1,214,000
Total $16,418,000
In order to deliver these projects in a timely manner, the following criteria were used to
develop the project delivery plan.
A 5-year renewable maintenance contract is required for the service of the entire SCADA
system.
PDP Pump stations will be designed SCADA-ready.
SCADA components (antenna modem, and PLC, where needed) will be provided by a
SCADA vendor (systems integrator) and installed by a general contractor. For PDP
pump stations and the North WWTP, the general contractor will be the general
contractor for the entire project.
The collection system SCADA will be separated by North and South, so that the North
Collection System will communicate with the North WWTP and the South Collection
System (consisting of both South and Central Basin pump stations) will communicate
with the South WWTP.
The SCADA vendor will be selected by a bidding process. The contract will be based on
the number of pump stations to receive SCADA per year, with a unit price given for
each type of unit for each year. The North WWTP SCADA system will be designed and
bid separately from the collection system SCADA.
The South WWTP SCADA system will be delivered on the Program schedule by 2014,
when the South WWTP – Phase 2 project is scheduled to be completed.
The North WWTP SCADA system will be delivered when the Master Plan project is
implemented in 2015 or beyond.
With these criteria in mind, the following project delivery plan was developed.
1) C-P will finalize a location for SCADA Operations Data/Control Center, preferably in a
downtown location.
2) PM will develop a plan to remodel roughly 300 existing pump stations that are not being
upgraded in the Program. Each pump station will need new SCADA equipment, with
