r i n group 2
1. Technical Approach to the Project
Scope of Work
A. Project Coordination
Preliminary/Project Kick -Off Meeting — A meeting will be held with the City Public Works staff
and RJN staff. This meeting will review the program objectives and time lines and define the
roles of each project team member. This meeting will also provide the overall framework, work
flow, and standards for the SSES program. Recommended topics include:
• I/I field investigation procedures
• Codes, standards, naming conventions, numbering systems, and forms
• Source data dictionary and flow quantification
• Program plan/basin prioritization refinement
• Data management/delivery
• Work flow/coordination
• Rights of access/traffic control
Project coordination will also include project mobilization.
Work Plan — A work plan will be presented at the onset of the project and will be used as a
"living" document to guide project activities. This plan will be a flexible tool and will be
modified/updated as needed. The work plan will provide a detailed schedule with dates and
milestones.
Quality Assurance/Quality Control (QA/QC) Plan — RJN has spent the last 35 years improving
processes and controls to provide reliable SSES data to clients. This project will be no different.
RJN has several points of project development where QC measures will define reliable
conclusions, I/I quantification, and the appropriate approach to recommendations. These
procedures will include a certain percentage of repeat field activities to determine if the repeated
inspection coordinates with the original one. Our flow balancing techniques, where flow
metering information is available, also provides the City with a high degree of confidence that
the UI investigation is comprehensive in its approach and major sources of UI are not overlooked.
The final QA/QC determination is the proof with the elimination of overflows and basement
backups in the areas reportedly where various wet -weather problems exist.
Progress Meetings — Regular progress meetings will be conducted with the City. Meeting
agendas and technical memorandums will be prepared and distributed prior to the meetings, and
meeting minutes/follow-up action lists will be distributed after each meeting. For purposes of
this proposal, it is assumed that progress meetings will be once every three weeks. It is
anticipated that the first monthly meeting will be one week after Council approval.
Project Tracking — RJN routinely uses thematic mapping tools such as ArcView to manage and
communicate the project status to team members and City staff. Thematic mapping is also used
rr n_r
to convey improvement and rehabilitation recommendations. Project tracking against the project
schedule developed as part of the work plan will also be conducted.
Historical Data Review/Data Collection — RJN will review the existing system maintenance
records and any trouble call reports. We will also review historical sanitary sewer overflow
reports, former investigation data, and operations data for pump stations in the service area. This
data will be used to prioritize study areas, determine investigation methods, and consider
alternative inspection methods to overcome any identified challenges.
B. Inspections and Testing
Manhole/Visual Pipe Inspection — RJN will perform comprehensive full -descent inspections of
manholes over 10 feet deep; those under 10 feet deep will be inspected from at grade. All
subsurface manhole components from the frame seal, walls, and manhole bench and trough will
be inspected. Visual pipe inspection will include invert measurements at each line segment, if
possible, in addition to detecting line conditions from the manhole. Photographs of major
manhole defects will be taken.
Dual -Blower Smoke Testing — This task will specifically identify sections of sewer lines and
sources where excessive I/I may be expected to occur during wet -weather periods including
locations of storm water transfer into the sanitary sewer system.
A dual -blower, intensified smoke technique will be utilized to test sewer lines in the selected
study area. This enhanced method uses two smoke blowers for each test segment instead of the
conventional technique of one blower. Experience has shown that four to six times as many
defects are observed using this method. Smoke testing will be performed only during dry
periods to maximize effectiveness of the smoke testing program. Locations and severity of the
smoke will be recorded.
Locations of all identified inflow defects will be shown on the geographic information system
(GIS) maps with all data and photographs of the defects.
The linear footage and manhole totals for each metered sub -basin to be inspected are:

Dye Tracing — It must be noted that smoke testing does not locate all discrete sources of I/I.
Because of that, it is important that another level of field screening be performed to provide the
r i n group 4
City with the confidence that they are receiving a comprehensive SSES program. Many of the
potentially major sources of UI cannot always be identified from smoke testing (i.e., downspouts,
driveway drains, and yard drains). RJN field crews will record "suspect sources" located on
private property during smoke testing activities. These suspect sources are sometimes "trapped"
and will test positive with dye tracing. Suspect sources will be followed up after smoke testing
with dyed water tracing using a non-toxic fluorescent dye, quantified, and inputted into the flow
quantification database when found to be connected to the sanitary sewer.
Dyed Water Flooding — Identified inflow from directly connected storm sewer facilities has the
potential to be a major contributor to extraneous flow during wet -weather events. Because that
potential exists and the City needs to understand the magnitude of the inflow to assist with
prioritization, inflow sources and quantifications from each source will be identified by means of
dyed water flooding of storm sewer sections and suspected overflows, stream sections, ditch
sections, and ponding areas that may be contributing to inflow. The dyed water flooding test
areas are based on results of the smoke testing program. Positive dye flooding tests are
quantified for leakage rate, especially sanitary/storm cross connections.
Inflow sources can be pinpointed by surface flooding sewer sections with dyed water to verify
storm sewer connections, suspected overflows, streams, ditches, and ponding areas that may
contribute to the system inflow. For purposes of this proposal, it is estimated that 32 crew days
will be required to complete dye tracing/dye flooding activities. The actual number of days
required will be based on the survey findings of smoke testing and will be performed on an as -
needed basis. Specific activities will be defined at the end of smoke testing activities.
Quantification and discrete cross connection location information will be recorded, along with
any attributes required by the City. CCTV will be performed as necessary and simultaneously
with dye flooding to better evaluate the source and correction required. Dyed water testing can
be effective during TV inspection to witness the source and quantify the magnitude of UI.
CCTV Work — CCTV is specifically used to pinpoint system defects, define their magnitude, and
determine the most -appropriate method of rehabilitation. RJN's CCTV contractor is Ace Pipe.
RJN will be providing field oversight and office -required CCTV review and analysis. RJN will
assist Ace Pipe in troubleshooting field activities such as structure location and identification and
coordinating map updates for new structures not located on facilities maps. RJN will also be
providing office review for all CCTV and performing the QC procedures. RJN has Pipeline -
Assessment -and -Certification -Program -certified (PACP-certified) personnel available for review
and QC activities.
All televised observations will be digitally recorded and provided electronically to the City.
Audio commentary will accompany the video inspection. The database will be provided in
WINCAN8 software format. Data will be collected and categorized using PACP standards.
During the course of field activities, line segments in need of cleaning activities due to excessive
debris are often identified. For purposes of this proposal, it is assumed that 10% of the total
linear feet will have CCTV and associated light cleaning. Throughout CCTV fieldwork, RJN
and Ace Pipe will coordinate any map update requirements.
r i n group
Wet -Weather Inspections — Certain areas such as tributaries and low-lying areas present
opportunities to physically witness the influence of I/1. During wet -weather periods, when
smoke testing is the least efficient, crews will perform aboveground reconnaissance. Through
wet -weather inspections, crews are able to witness 1/I and observe system anomalies as they
occur to better pinpoint and quantify them. For purposes of this proposal, it is assumed that a
total of eight wet -weather days will be used for inspection by field crews. Dye test crews will be
provided to perform these inspections.
C. Data Analysis and Reporting
Quantification and Balancing of Inflow Defects — Field survey information including observation
of physical conditions and I/I source leakage rates provides the database needed for
quantification of individual 1/1 source defect flow rates under design storm conditions. These
defect flow rates are based on specific 1/1 source flow rate equations. Balancing of inflow
defects is performed on separate sewer system studies where flow monitoring data are available.
Flow rates based on actual field observations can also be entered during the data input process.
RJN will estimate flows for each defect identified based on the 1 -year, 30 -minute storm event.
Rehabilitation methods and costs, along with I/I source flow rates, vary according to the physical
characteristics of the individual defects identified and prioritized.
Immediate Action Repairs — RJN field technicians are trained to identify critical situations
requiring emergency attention. Situations may be identified during fieldwork that pose
significant risks to public safety, the environment, or the structural integrity of the collection
system. These will be reported to the City immediately to ensure public safety and to protect the
environment. Standard protocols for communication and initiation of procedures leading to
design and implementation of critical repairs for high-risk situations will be defined during
project initiation. Potential types of critical situations include:
Manholes without covers in public areas
Active dry -weather system overflows
Collapsed pipes in streams
There will be three processes related to data delivery.
1. One process will be the hand entry of data collected, smoke testing, dyed water flooding,
and building inspections.
2. CCTV data will be supplied in a compatible format to that of the City's.
3. Manhole inspection data will be inputted into our CASS database, and the completed
database will be submitted to the City.
ringroup 6
GIS Data Delivery — In addition, shape files will be developed of defect data for submittal to the
City.
Selection of Rehabilitation Methods — Once all defects have been located, quantified, and
prioritized, decisions can be made on the approximate repair method for each identifiable defect.
There are various design and construction techniques that can be implemented as part of the
recommendation and design solutions of this project:
• Conventional open cut
• Trenchless technologies (cured -in-place pipe [CIPP], pipe bursting, pipe reaming, slip
lining, etc.)
• Private inflow source removal
• Private lateral repairs
• Manhole rehabilitation/replacement
• Point repairs
• Pump station upgrades
• "Green" low -impact development techniques
Each solution developed by RJN will be based on our knowledge and 35 years of experience
with UI quantification and collection system performance.
D. Final Report and Recommendations — Technical memorandums summarizing specific tasks
will be submitted upon completion of fieldwork and data analysis. Quantified total 1/I and
removal recommendations will be provided in our standard SSES report format. Defects will be
graphically illustrated on a GIS map to show location and severity of defects and included with
the report. The draft reports will be submitted to the City and finalized based on one set of
comments from the City. Three final report copies with related data and respective DVD
appendix will be submitted to the City.
Rehabilitation methods that will be evaluated for 1/I removal will include repairs of manholes,
sewer mains, interceptors, and laterals. Typical manhole repairs include complete replacement,
frame sealing, grade adjustment, manhole wall coating and grouting, pipe seal repair, bench and
trough repair, and manhole lining. Mainline and interceptor rehabilitation methods will include
point repairs; rerouting, capacity improvements, or replacement; section replacement; and
trenchless technology such as slip lining, CIPP, bursting or crushing, or directional drilling.
Lateral repairs will include replacement, point repairs with emphasis on lateral -to -main
connections, trenchless methods, and cleanout repairs. Current rehabilitation costs will be used
and updated as necessary. Recommendations will be graphically represented on a GIS -based
map and included as part of the report.
The GIS deliverable will provide a spatial comparison between the current GIS layer and the
global positioning system (GPS) sewer layer. It is essential to carefully associate GPS -surveyed
manholes with the City's GIS to preserve the integrity of the GIS feature identifiers and related
attribute data. RJN will deliver a GIS project file and source data for migration into the City's
GIS system. Thematic maps representing defects and recommendations will be developed as
part of the report.
