Aeration Basins Improvements Project – Scope of Work
Project Management
Project Management includes project set-up in KJ’s Project Management system; monitoring the scope, schedule, and
budget during the project; managing, and coordinating
the KJ team and subconsultants; preparing a Health and
Safety Plan for work at the plant site; and establishing project quality assurance/ quality control procedures,
communications and invoicing with the City.
Deliverable: Health and Safety Plans and Invoices.
Phase I – Condition Assessment and Evaluation
Task 1 - Project Kickoff Meeting
This task will include a kickoff meeting at the Laguna
Wastewater Treatment Plant with the KJ team and City staff.
The task will also include a tour of the plant site including the settled sewage channels, aeration tanks, mixed liquor channels, flow equalization basins and final clarifiers.
The intent of the site tour is to get the KJ team familiar with the plant facilities involved in the project. KJ will also perform a visual survey of potential locations of air leaks in the low-pressure air piping and locations where diffusers may be plugged or damaged. The City will provide input into the visual survey based on their experience at the facility.
Deliverable: Agenda and Meeting Notes.
Task 2 - Develop Initial Bypass Plan
KJ will develop initial alternatives for bypass of the flow around the settled sewage channel and the mixed liquor
channels including potential temporary channel bulkheads that may be advantageous along with tentative schedules for the bypass, dewatering, cleaning, and inspection work.
A bypass plan will be drafted and reviewed as part of Task 3 below. Once the bypass plan has been reviewed the plan with any initial alternatives will be submitted to the City for review.
Deliverable: Initial Bypass Plan.
Task 3 - Constructability Review of Bypass Plan
The Bypass plan will be reviewed by a KJ experienced
Construction Manager, Tom Gorman, to verify the
constructability of the concepts and identify any fatal flaws that need to be addressed prior to submitting the plan to the City for review.
Deliverable: Technical Memorandum.
Task 4 - Workshop for Bypass Plan
A workshop will be held to discuss the draft bypass plan and any question or concerns of the City. The goal of the workshop will be to agree on a workable plan to bypass
flow around the channels for dewatering, cleaning and
inspection of the channels, the low-pressure air piping, and any diffusers. It is our understanding that the aeration basins can be individually isolated for dewatering, cleaning, and inspection.
Deliverable: Final Bypass Plan.
Task 5 - Develop Work Plan for Dewatering and
Cleaning
Based on the outcome of the bypass plan workshop, KJ will develop a work plan for the City to use in hiring a Contractor to setup the flow bypasses, dewater and clean the isolated channels and the aeration basins. The work plan will
contain plans on mylar of the proposed bypasses and
details for flow distribution to the secondary clarifiers and specifications necessary for the City to hire a Contractor.
Deliverable: Work Plan.
Task 6 - Inspection of Basins, Channels and Low-
Pressure Air Piping
Once the settled sewage channels, mixed liquor channels and aeration basins are dewatered and cleaned and while they are still isolated, KJ will send a team of at least three engineers to enter the channels and basins to inspect
the low-pressure air piping, air diffusers and concrete structures. It is anticipated that the inspections will take at least two visits to the site as the aeration tanks cannot all be down at one time. The inspection of the entire facility may take three visits depending on when the bypassing of the channels will occur. In addition to the KJ personnel our subconsultants for coatings and cathodic protection will also participate in assessment of the existing conditions.

Task 7 - Draft Technical Memorandum
Based on the finding of the inspections of the dewatered channels, aeration basins and the low-pressure air piping, KJ will prepare a draft Technical Memorandum with our
findings, evaluation of the condition of the existing facilities and recommendations for any rehabilitation of the existing structures and rehabilitation or replacements of the low- air piping and associated diffusers. This draft Technical Memorandum will be submitted to the City for review.
Deliverable: Draft Technical Memorandum.
Task 8 - Workshop on Draft Technical Memorandum
A workshop will be held with the City to review and
discuss the draft Technical Memorandum including the
recommendation for improvements to the channels, basins, low-pressure air piping and diffusers.
Deliverable: Agenda and Meeting Notes.
Task 9 - Final Technical Memorandum
Based on input from the City during the draft Technical Memorandum workshop and any other comments from the
City, KJ will prepare a final Technical Memorandum of the inspection finding, facility evaluation and recommendations.
This final Technical Memorandum will be the basis for the initial design in the following Phase II portion of the project.
Deliverable: Final Technical Memorandum.
Phase II - Design
Task 1 - Kickoff Meeting with City
This task will include a kickoff meeting between the City staff and KJ to discuss how the flow bypassing went during Phase I of the project and if what was done during Phase I will work for the construction of the improvements or if some changes should be made to accommodate the
Contractor and to optimize the operations at the aeration basins. Any agreed to modifications or changes to the
bypass configurations and constraints for the bypassing will be included in the design.
Deliverable: Agenda and Meeting Notes.
Task 2 - Prepare 30% Design and Basis of Design

Subject: Proposal for the City of Santa Rosa C02096 Laguna Treatment Plant Aeration Basins Improvements Project Dear Tanya:
Kennedy/Jenks Consultants, Inc. (KJ) offers the City of Santa Rosa (City) the most qualified team with a proven method to address the filter valves and actuators replacement and aeration basins improvements at the Laguna Treatment Plant (L TP).
We provide key benefits to the City:
Hands-on Experience at Your Facilities: Our proposed local task leaders have extensive experience at the L TP , engaged in condition assessments, designs, hydraulic evaluations, and the current replacement of the aeration basin header. Their knowledge of the structures will produce a rehabilitation strategy that extends the life of the basins for decades in a cost- effective manner.
A Cost-Effective Approach to Rehabilitation: KJ will focus on condition assessment and rehabilitation, rather than process design. Our focus on concrete, piping failure, coatings, and localized leaks will be the most cost-efficient for Santa Rosa.
We will focus on key areas that are most effective for restoring the basins. We will not automatically recommend replacing all pipes. Our knowledge of the basins tells us that much appears to be in good shape. We will focus on areas with the highest risk and likelihood of failure, including the channels, areas where air can be seen under the surface. This risk- based approach will provide the best stewardship of Santa Rosa’s budget.
A Systematic Plan that Minimizes Treatment Disruption: We have a plan to sequentially dewater the basins, perform efficient condition assessments and perform repairs with approval and coordination with the plant operators for minimal disruption or risk. Our work plan for assessment and construction phases will assure that all four basins are online during the rainy season from mid-October to mid-March. Cost-saving ideas, such as using the same bypass system in place during both assessment and construction will add value to your investment.
Value-Added Services: The KJ team offers additional value-added services, including:
» Providing efficiency in the assessment process for both the Filter Valve and Aeration Basins projects with the same team.
» Offering the option of installing flow meters on the piping, while the basins are dewatered, to allow better control of the system for the long-term, while taking advantage of planned maintenance. » Evaluating the diffusers to determine if newer technology may improve process performance. » A constructability review by our expert Tom Gorman to support the most cost-effective construction plan and estimate
» Cathodic Protection and Coatings Assessment from our subconsultants to provide the highest level of expertise.
We commit our team to you and we offer a work plan that will result in a successful project. I, John Wyckoff, am an official authorized signer and will be your point of contact. KJ would be pleased to work with you on these projects.
Very truly yours,
Kennedy/Jenks Consultants, Inc.

PROJECT PROOF
KJ has successfully completed similar projects, in which wastewater treatment components were rehabilitated while the overall system remained active and in complete compliance. Our work for the City of Palo Alto’s Secondary Clarifier, DMF and the Primary Sedimentation Tank Improvements Project is a testament to our ability to assess and rehabilitate facilities while maintaining plant flow and treatment operations.
Aeration Basins Improvements Project
Project Understanding
The City of Santa Rosa Water Department’s L TP serves the Cities of Santa Rosa, Rohnert Park, Sebastopol and Cotati and the South Park Sanitation District. The activated sludge process includes settled sewage channels, aeration basins, and mixed liquor channels, along with a low-pressure air system for secondary (biological) treatment at the facility.
There are currently four aeration basins at the facility which are required to treat the peak wet weather flow at the plant.
During the dry weather season, mid-April through mid-
October, when average dry weather flows are expected,
only two of the aeration basins are required for treatment.
The low-pressure air system supplies air to the aeration basins through diffusers in the bottom of the tanks. The low pressure-air system also supplies air to the settled sewage channels and the mixed liquor channels to mix the contents of the channels and reduce settling of solids in the channels.
The City staff has identified leaking piping and plugged diffusers in the low-pressure air system. This project includes inspecting the condition of the channels (settled sewage and mixed liquor), the aeration basins and low-pressure system and recommending necessary improvements to
provide rehabilitated facilities that serve the community for decades into the future.
The activated sludge system must remain in service and
continue to treat the wastewater flows to meet discharge requirements without disruption. It is our understanding that during the dry weather season the City staff can take two of the four aeration basins out of service for inspection of the basin, low pressure piping and diffusers, while not adversely affecting the quality of the treatment plant effluent.
The Settled Sewage and Mixed Liquor channels are a
different story, as portions of each of these channels carry the entire plant flow independent of which or how many
aeration tanks are in service. Therefore, bypass systems will be necessary to take portions or all these channels out of service for inspection of the channel integrity and low-pressure piping condition. This bypassing of flow for rehabilitation of the channels, low-pressure air piping and diffusers would also be required during the construction phase of the project.
Detailed Project Approach
Design of this project will be accomplished in three main Phases: I. Condition Assessment and Evaluation, II. Design, and III. Bidding.
KJ staff will work closely with the City’s staff throughout the project. We will host regular meetings with staff, provide ample review periods for review of submissions and hold workshops after each major submittal. In this way, we
intend to utilize the City staff’s knowledge of their facility and how it operates and encourage input into decisions
based on their preferences and experience at the plant.

Phase I. Condition
Assessment and Evaluation
During Phase I of the project, KJ will work with City staff to develop an approach for cleaning and inspecting the
settled sewage and mixed liquor channels as bypassing of flow will be required to keep the plant in operation. It is our understanding that, normally, primary effluent is sent to the aeration tanks through the settled sewage channels and
any instantaneous flow over a predetermined amount is
directed to the flow equalization basins and not sent through the settled sewage channel for treatment during periods of lower flow. To provide for enough time to properly dewater, clean and inspect the settled sewage channel, the entire plant flow will need to be directed to the flow equalization basins.
A temporary bypass pumping system would be installed
to pump primary effluent from the flow equalization basins directly to the aeration basins, bypassing the settled sewage channels. This bypass would allow enough time to properly dewater, clean and inspect the settled sewage channels, along with the associated low-pressure piping and diffusers in those channels. This bypass system would be scheduled for the dry weather season when flows would be less than the winter peak flows, and the bypassed flow would only need to be pumped to two of the aeration basins, allowing two of the aeration basins to be taken down for inspection.
Since most of the mixed liquor channel carries all the plant flow from the aeration basins, bypassing flow around this channel would also be required to allow enough time to
properly dewater, clean, and inspect this channel. We will work with City staff to coordinate this work and develop a scheme that satisfies the plant operators. It is anticipated that bypassing of the mixed liquor channels will be
accomplished during the same dry weather season as the
bypassing of flow and dewatering of the settled sewage
channel.
During the bypassing of the mixed liquor channel the
second set of aeration basins will be taken out of service for dewatering, cleaning, and inspection with the first set inspected having been put back into service. Bypassing of the mixed liquor channel would be performed by pumping
mixed liquor directly from in-service aeration basins to a temporary distribution box setup near the secondary
clarifiers. This temporary distribution box would be designed to provide for splitting the mixed liquor flow equally to the secondary clarifiers that are in service.
A plan for bypassing flow and dewatering and cleaning the basins and channels will be developed and discussed with City staff in a workshop (See Figure 1 on the following page).
Because the basins and channels will need to be shut down and dewatered for any repair or rehabilitation work of the structures and any replacement or rehabilitation of the low- pressure piping in the channels and basins, it is anticipated that a single bypass plan can be developed and utilized for both the Phase I - Condition Assessment and Evaluation
and the Construction. Utilizing the developed bypass plan, we will prepare a work plan for the dewatering and cleaning of the Aeration Basins, Settled Sewage Channel and Mixed Liquor Channel.
The work plan will include drawings and specifications.
The City will utilize this work plan to hire a contractor to dewater and clean the channels and the aeration basins in preparation for the conditions assessment.
Prior to taking the basins and/or channels out of service, a visual survey will be performed from the surface of the basins and channels to locate areas where air leaks are possibly occurring and/or where diffusers are plugged or damaged. Then, we will perform inspection of the aeration basins, the settled sewage channels, the mixed liquor
channels, the low-pressure air piping, and diffusers after the bypass system has been constructed and the facilities have been dewatered and cleaned.
Particular attention will be paid to any locations identified as possible piping leaks or diffuser damage identified in the visual survey. It should be noted that there is an FRP low pressure-air header that is buried below the concrete sidewalk on the West side of Aeration Tank 2. This FRP line will be inspected from the inside using video equipment to avoid the demolition of the entire sidewalk along the west side of the Tank.
PROJECT PROOF
At the City’s LTP Clarifier No. 3 Rehabilitation,
KJ completed the condition assessment within
two weeks of receiving Notice to Proceed.
KJ will perform the structural inspection of the channels and aeration basins utilizing an engineer familiar with the structural design of this type of facility and who has experience with performing this type of inspection. Low- pressure air piping and diffusers will be visually inspected by Kennedy/Jenks Consultants, Inc.

engineers familiar with air piping and air diffuser systems.
In addition, an inspection of any coating in the channels and basins or on the low-pressure air piping will be inspected along with any cathodic protection in place.
PROJECT PROOF
In the Silicon Valley Clean Water’s Digester
Rehabilitation project, we paid special attention
to assessment and replacement of coatings.
Once the inspection work is completed, an evaluation of the findings will be performed and a technical memo, TM, prepared for submission to the City. This TM will detail the results of the evaluation and include recommendations for rehabilitation of the structures, low- pressure air piping and diffusers. We will host a workshop with City staff to discuss the findings and recommendations.
We will also take the opportunity to discuss how the
bypassing of flow for the inspection went and if any
modifications are needed to the bypassing plan for future phases of the work. After the workshop a final technical memorandum will be prepared with the recommendations
for the rehabilitation of the facilities to be designed in Phase II of the project.
Phase II. Design
Phase II Design will begin with a kickoff meeting between KJ staff and the City to discuss the direction of the design project. KJ will then prepare the preliminary 30% design, a basis of design report (BODR) and an engineer’s opinion of probable cost of construction. The 30% design will include initial plans for the recommended alternative that is detailed enough to produce the engineer’s opinion of probable cost of construction.

At the 30% design, value
engineering will consider pipe
material, corrosion protection
(corrosive resistant materials,
coatings, cathodic protection),
and diffuser selection.
75% design will include
advanced drawings, technical
specifications and opinion of
probable construction cost,
assuring your comments are
implemented.
A thorough visual
survey will find
obvious air leaks,
prior to any
dewatering or

Inspection and
repair of channel
and basin concrete
will result in a
reliable secondary
process.
The FRP low pressure-
air header under the
concrete sidewalk near
Aeration Tank 2 will
be video inspected to
avoid demolition of the
sidewalk, saving time,
disruption, and money.
Final design and
construction
services will
support successful
completion of the
project.
DESIGN
The BODR will include descriptions of materials of construction, recommendation for diffusers if required, recommended procurement strategy for equipment, a flow bypassing plan based on Phase I experiences, and a construction phasing and scheduling plan.
At this time, it is assumed that construction of the improvements will be limited to dry seasons and therefore two consecutive dry seasons will be required to complete the construction phase.
A workshop with the City staff will be held to discuss the 30% design and the BODR. This workshop will include a value engineering session to consider alternatives for pipe material selection; corrosion protection such as corrosive resistant materials, coatings, cathodic protection; and alternatives for diffuser selection. Comments and input from City staff during their review of the 30% design, BODR and engineer’s opinion of probable construction cost will be utilized to advance the design to a 75% stage.
The 75% design will include advanced drawings, draft technical specifications, a constructability review and an updated engineer’s opinion of probable construction cost. The 75% design will be submitted to the City and after City review, a workshop will be held to discuss comments and concerns. After this 75% review workshop, the design will be advanced to the 90% design stage and will include details and updated technical specifications.
At this stage, KJ will also submit a proposal for Engineering Services During Construction. The 90% design package will be submitted to the City, and a final design workshop will be held with the City to discuss the review comments. Based on comments on the 90% submittal, KJ will prepare a final set of Construction Documents.
Phase III. Bidding
Once the Construction Documents are advertised, KJ will proceed with Phase III and respond to bidder’s questions, prepare addenda, and attend a pre-bid meeting. Once bids are received and a Contractor selected for the project, KJ will prepare a conformed set of Construction Documents that include any updates or changes that were made by addenda.
