ENGINEERING SERVICES FOR
RECYCLED WATER PROJECT
SCOPE OF SERVICES
INTRODUCTION
The purpose of this Task Order is to provide the CITY with engineering services in conjunction
with design of the Redlands Recycled Water Project Treatment Facilities. The Regional Water
Quality Control Board is requiring the CITY to take measures to increase the plant's ability to
remove total inorganic nitrogen (TIN) from its effluent. In addition, the CITY desires to add
facilities that will produce recycled water that meets all the regulatory requirements contained in
Section 60304 (a) and Section 60306 (a) of Title 22, Division 4 of the California Code of
Regulations. Reliability requirements for Recycled Water Project Facilities will be based on
Mountainview Power Company providing a standby system.
This project will provide the facilities to increase treatment of TIN to 10 mg/L or less for a rated
capacity of 9.5 mgd. Major design elements that have been indicated in the scope of work are:
1. Anoxic Basin with Mechanical Mixers
2. Demolition of the Existing Rapid Bloc Structure
3. RAS Pump Station No. 2
4. Nitrification Clarifier No. 4
5. Yard Return Piping
This project will also provide for facilities to produce 6 mgd recycled water. Major design
elements that have been included in the scope of work are:
1. Tertiary, Filtration System
2. Disinfection System
3. Filtration Influent Pump Station
4. Interplant Transfer Pipeline
The Treatment Alternative Feasibility Study will consider the processes identified above as the
base project. Two additional process treatment scheme alternatives (with sub-alternatives) will
be developed and compared with the base project using an Evaluation Matrix developed jointly
by the CITY and ENGINEER. Through a series of workshops, the CITY and ENGINEER will
select the best-fit project, Upon selection of the best-fit project, CITY and ENGINEER agree to
review Scope of Services presented herein and to make appropriate adjustments to Scope of
Services for preliminary design (T.O.1) and final design (T.O. 2).

SCOPE OF SERVICES
To provide the needed engineering services to evaluate alternatives and prepare the preliminary
design, the following tasks will be completed.
TASK 1 • TREATMENT ALTERNATIVE FEASIBILITY STUDY
1.1 Technical Memoranda
ENGINEER will develop technical memoranda (TMs) to comprise the Treatment Alternative
Feasibility Study. ENGINEER and CITY will meet in a series of four (4) workshops in which
ENGINEER will present drafts of designated TMs. CITY will provide input and review
comments. As agreed to by CITY and ENGINEER, appropriate comments will be addressed in
the TMs. The ENGINEER will prepare the following TMs:
a. Water Quality and Flow Requirements for MPC.
b. Title 22 Requirements for Cooling Water and Water for Irrigation.
c. Criteria for Evaluating Alternatives.
d. Alternative Treatment Approaches for Recycle Water and TIN Modifications.
e. Expansion Considerations to 9.5 mgd.
f. Upgrades to the Existing Plant Necessary for the Recycled Water Facility and TIN
Removal.
g. Construction Costs and Life Cycle Costs.
h. Evaluation of Alternative and Final Summary.
1.2 Develop Alternatives
ENGINEER will develop three alternatives as described below:
Alternative 1: Tertiary Treatment of Secondary Effluent/TIN Upgrades— Base Project
This Base Project Alternative will consider previous reports presented to the CITY regarding
increasing capacity to remove TIN to equal to or less than 10 mg/L for an average annual flow
of 9.5 mgd. It is anticipated the following facilities will be required:
a. Anoxic Basin.
b. Recycled Mixed Liquor Pump Station.
c. Nitrification Clarifier No. 4.
d. RAS Pump Station No. 2.
e. Transfer Piping.
f. Miscellaneous Yard Piping and Splitter Boxes.
Recycled water facilities that may be required include the following:
a. Tertiary Filtration (both traveling bridge/self-backwash and continuous backwash
system).
b. Chlorine Contact Basin.
c. Chlorine Chemical Feed Facility.
d. Filtration Influent Pump Station.
e. SCADA for Water Reuse System.

Alternative 2: RIX-type Treatment of Secondary Effluent
The facilities presented in Alternative 1 for TIN removal will be common to this alternative.
Facilities to provide a RIX-type system may include the following:
a. Extraction Wells.
b. Monitoring Wells.
c. Disinfection system which may be either UV or chlorination with contact basin. Both
subalternatives would be considered.
Alternative No. 3: Membrane Treatment
This alternative will evaluate each of four subalternatives for membrane microfiltration. For each
subalternative, where applicable, preliminary sizing of permeate pumps will consider the
feasibility of maintaining an elevated hydraulic grade line to facilitate conveyance of filtrate to
the recycled water distribution pipeline(s). The subalternatives are summarized as follows:
3A - Membrane in the Existing Nitrification Basins
Under this alternative, each of the existing nitrification basins would be retrofitted to house
3 mgd of microfiltration modules. Adequate accessibility to clean and maintain the
membranes, as to well as maintain the aeration system, would be evaluated. Disinfection
would be the same as in Alternative 2.
3B-Add Membranes to Existing Rapid Bloc
This alternative is similar to Alternative 3A except that membranes would be installed in
the existing Rapid-Bloc structure rather than in the nitrification basins. Disinfection
evaluation will be similar to that of Alternative 3A.
3C- Membrane Treatment in New Bioreactor
This alternative is similar to Alternative 3A, except that a new structure would be located in
the plant area now occupied by the Rapid-Bloc system. Disinfection alternatives would be
similar to those of other membrane alternatives.
3D - Membrane(Stand Alone) System
This alternative would use microfiltration to treat clarified secondary effluent in a
standalone microfiltration system. Disinfection alternatives would be similar to other
membrane alternatives.
1.3 Upgrades for TIN/Membrane Treatment
TIN replacement for Alternatives 3A and 3B.
This subtask will address existing TIN removal capacity lost due to use of existing tankage to
support membrane treatment alternative for Recycle Water Project.
TASK 2 - UPGRADES TO EXISTING FACILITIES
CITY staff and ENGINEER will perform independent investigations of the existing facilities. The
useful life of mechanical and electrical equipment will be considered along with advancements
in energy efficient equipment. The design will include the following plant upgrades:
2.1 At the existing Headworks, replace the bar screens, recoat needed interior concrete
surfaces, replace grit chamber air piping, provide a new grit handling system, and provide
miscellaneous appurtenances.
January 8, 2001

2.2 At the Headworks Pump Station, replace existing motors with high efficiency motors and
replace variable speed drives with electrical variable frequency drives.
2.3 The existing chlorination system would be replaced to provide in-plant operational
chlorination needs.
2.4 At the Peak Pond Pump Station, replace the pumps, motors, and drives with new
equipment.
2.5 At the Blower Building replace the blowers and drives.
2.6 At the RAS Pump Station for Secondary Clarifiers No. 1 and 2, replace the RAS and WAS
pump, motors, drives, and control system. Add a magnetic flow meter to the WAS line for
operational control.
2.7 At the Final Effluent Pump Station, replace pumps, motors, and drives of the effluent
pumps.
2.8 At the Dissolved Air Flotation System No. 1, replace the pressurization system and
controls.
2.9 Replace existing high pressure air system.
2.10 Replace Grit Chamber air feed lines.
2.11 For the existing electrical system the ENGINEER will provide a Third Party subconsultant
to evaluate the condition of the existing electrical system. Refer to Task 5—
Subconsultants for a more detailed Scope Of Services.
