Work Order Number 13
Roseland Elevated Tank Conversion
to
Repump Station
PROJECT UNDERSTANDING
Indian River County Utilities(IRCU)owns and operates the Roseland 750,000 gallon elevated
storage tank, which is a steel hydro-pillar type that has a common inlet/outlet pipe that allows
distribution water to fill and drain the tank,depending on system demands. Currently, an altitude
valve controls the filling of the tank,but does not have the ability to drain and charge the
surrounding water distribution system, since the tank operating level is much lower than normal
system pressures.
Several evaluations were conducted, one by Neel- Shaffer in 2007, and the latest recently by
Kimley-Horn and Associates,Inc. in 2015,to determine the most cost effective method of
correcting the elevation shortfall and optimize use of the elevated tank. The options which were
considered were raising the tank,constructing a taller one adjacent to the existing one, or
converting the existing tank to an elevated storage and repump facility. The last option of
converting the tank to a storage and repump station that provides remote storage and repumping
to the North Roseland service area is recommended. This allows the utilities the ability to
maintain and optimize use of an existing asset and address future fire flow requirements for this
area. The water distribution system hydraulic model,updated in July 2014,identified this area as
an area having low pressures during peak demands and having difficulty meeting fire flow
demands.
Modification of the elevated storage tank to include repumping facilities will require
modifications to the inlet and outlet piping configuration,requiring a new separate fill line to the
storage tank. It is assumed that a new 12/16-inch water line, approximately 500 ft long will be
required base on the current distribution piping model and GIS information.
Based on the following assumptions and the scope of the project described herein,an opinion of
probable construction costs are estimated to be$950,000.
The following is a list of assumptions that the Consultant has made in the preparation of the Task
Order.
1. A new separate waterline to act as a fill or outlet pipe will be needed to separate the
pressure zones for a repump and storage facility. The length is assumed to be
approximately 500 ft, and be a 12-inch or 16-inch waterline.
2. At least two (2),with one spare,booster pumps will be needed sized for fire flow as a
minimum to boost pressures appropriately
3. Power and control panels are assumed to be housed within the pillar housing of the
elevated storage tank, and no new electrical building will be included. Variable
frequency drives (VFD's)will be designed for the booster pumps.
4. Remote telemetry at the North County RO water plant will be upgraded to include
monitoring and control of the new pump station.
5. The altitude valve will be replaced with an electric actuated control valve that can
maintain consistent and constant inlet pressure to the tank inlet pipe.
6. An outdoor rated generator and fuel storage tank with automatic transfer switch (NEMA
4X rated)will be included. It is assumed that a Tier 4 generator rating will not be
required.
7. The Consultant will provide an operating logic for the control system. The contractor
selected by IRCU will be responsible for any programming required to implement these
SCADA changes. Programming is not included in Consultants' scope.
8. The project will be prepared as one bid document
9. Minor site plan and administrative approval required only
The following scope of services consists of survey,preparation of drawings and specifications,
mechanical, civil,process,and electrical design,Florida Department of Environmental
Protection(FDEP)permitting,bidding phase services, and construction phase services. SCADA
system programming is not included but described below.
SCOPE OF SERVICES
Task 1--Topographic Survey—Site and Watermain
Consultant will prepare limited topographic survey of the footprint of the tank site and 500-ft of
watermain from Roseland Rd. All work will be constructed on Indian River County owned land

of the following items:
• Obtain existing elevations within a 100 ft x 100 ft area around the existing elevated
storage tank
• Obtain existing elevations within a 20-ft easement approximately 500 ft long from the
tank site to Roseland Rd
• Location of above ground improvements in the same area
