SCOPE OF SERVICES
INTRODUCTION
The purpose of this Task is to provide the City with final design engineering services for the Redlands Recycled
Water Project treatment facilities.The City desires to add facilities that will produce high quality recycled water to
be available for approved uses. in addition,the City is taking measures to further increase the plant's ability to
remove Total Inorganic Nitrogen(TIN)as required by the Regional Water Quality Control Board.The project is
based on Treatment Alternatives Feasibility Study,Alternative 3C dated April 25,2001,and as identified in the
Preliminary Design described in the 30%Drawing Submittal dated August 2001.
SCOPE OF SERVICES
Performance of necessary engineering work to develop contract documents for construction of the following
facilities and upgrades at the Wastewater Treatment and Disposal Facilities:
Task 1—Upgrades to existing facilities:
1.1 Peak Pond Pumps:Replace all pumps,motors,and hydraulic-clutch type drives with new pumps,high
efficiency motors and electrical variable frequency drives. The capacity of each pump should be increased
to 7.5 mgd.
1.2 Final Effluent Pumps:Increase the capacity of the two pumps to meet the flow requirements for a 9.5 mgd
treatment plant.The third pump will be used as standby for process reliability. Replace motors with new
high efficiency units with new variable frequency drives.
1.3 Aeration Blowers: Replace blowers and all associated accessories with similar,more energy efficient units.
New blower size to be determined by air requirements of the upgraded Aeration.Basins.Provide a standby
unit for reliability.Replace the Motor Control Center(MCC)as required to match the new blower units.
1_5 Miscellaneous Piping Modifications:Treatment Alternative Feasibility Study identified Auxiliary System
piping upgrades that would be included as presented in that report.
1.7 Electrical System:Testing will be required to determine the condition of the existing facility.Work to
replace existing electrical system will be phased in at a later date.
Task 2—Recycled Water System
2.1 Provide the design for selected Alternative 3C to include the construction of a new MBR tank external to
the existing NDN basin.At the MBR tank,mixed liquor would be recycled to the anoxic zone of each pass
to maintain the high mixed liquor concentration. The MBR would be compartmentalized such that
membranes could be cleaned in place.
2.2 During Preliminary Design the terms and conditions of a contract was negotiated with Zenon
Environmental Corporation to supply their membrane system.The system would be complete with pumps,
blowers,and a chemical feed and storage system as required to clean and operate the membrane system for
6.0 mgd normal flow.This Task Order would provide the structural and mechanical design for the Zenon
Membrane System.In addition,electrical Motor Control Centers will be included in the design.
A- I
2.3 Provide the design of the side stream screening as recommended by Zenon.
Task 3—Dentrifieation Facilities
To include upgrades to the existing nitrification system as follows:
3.1 Reconfigure the existing west aeration basins to treat 6 mgd.Convert the three-pass basin to three single
pass plug flow basins designed to increase TIN removal. Include a new flow splitting system and splitter
box.
3.2 Reconfigure the existing east aeration basins to treat 3.5 mgd and convert the basins to operate as a 3-pass
serpentine process with anoxic zones for dentriifcation.
3.3 Modify the tank structures to accommodate the process revisions.
3.4 Provide new aeration blowers and diffusers to meet new design requirements.
Task 4—LTV Disinfection
4.1 The alternative for disinfection was determined in Preliminary Design to include an Aquionix inline UV
system.Aquionix proposed three(2 duty plus I standby)inline 35000 series reactors to meet 6 mgd flow
conditions and satisfy Title 22 requirements. Final design of this disinfection system is included in this
Task Order.
Task 5—General Facilities
5.1 Paving,grading,and yard piping to support Tasks 1 thru 4.
5.2 Electrical to support Tasks 1 thru 4.
Task 6—Control Building
6.1 Provide final design for the Control Building/EIectrical Room as identified in the Preliminary Design
Building to house PLCs as provided by Zenon. In addition,the Electrical.Room will house all MCCs for
Membrane System and as determined for the existing facilities during the field test to be provided by ETI.
Task 7—Instrumentation and Controls
7.1 Provide coordination and specifications for instrumentation identified for the Membrane System and UV
Disinfection System.
Task 8—Electrical
8.1 Electrical to support Task I thru 7.
Optional Scope Items
Items not included in this Task Order.
I. Additional coordination and negotiation with Zenon Environmental Corporation regarding guarantees and
prepurchase of the membrane system.
2. Revisions to the Front End Documents for bid purposes.
3. Title 22 Report for the proposed facility.
4. Construction cost estimate.
5. Negotiation and pre-purchase of UV disinfection system.Also interface with Department of Health Services
regarding approval of the selected system.

6. Constructability review and project sequency,
7. Bid Period services
8. P&lDs for existing facilities and to upgrade to new SCADA system.
9. Design of rehabilitation of the headworks structure.
10. Revisions to the DAF system.
11. RAS/WAS Pump Station upgrades.
