James R. Dilorio Water Reclamation Facility?
RECOMMENDATION
Approval of Resolution
BACKGROUND
The James R. Dilorio Water Reclamation Facility treats wastewater collected
from the City of Pueblo. The Water Reclamation Facility is located near the
Arkansas River at the east end of Stockyard Road. Part of the treatment process
is carried out in partially buried concrete tanks.
The buried tanks are subject to pressure from groundwater in the surrounding
soil. The tanks are normally filled with water, and the pressure of water
contained in the tanks normally opposes the pressure exerted by groundwater,
so that internal and external pressures on the tank walls are balanced. However,
when the tanks must be emptied for maintenance, the pressure exerted by
groundwater is capable of damaging the concrete walls of the tank. This
�"' occurred in 2000, when the floor of a tank was broken by groundwater pressure.
In order to allow for periodic maintenance work to be performed without
damaging the structures, it is necessary to lower the groundwater level.
,.-. Dewatering will only be performed when a tank needs to be emptied. To satisfy
Colorado water rights, groundwater will be discharged to the Arkansas River to
which it is tributary.
The first phase of the proposed project includes a study of geohydrology to
determine the elevation of the water table, fluctuations in water table elevation,
sources of groundwater, and the influence of factors like sedimentation in the
Arkansas River on water table elevation. The first phase of the project also
includes design of a network of dewatering wells that can be used to lower the
water table near a structure that requires maintenance so that the structure can
be drained without damage. The second phase of the project, spread over
several years, will involve permitting and constructing a series of dewatering
wells.
Three proposals were received from consulting engineering firms for this project.
A summary sheet is attached. The proposals were evaluated on the basis of the
experience of each firm, the expertise of the staff and subcontractors
participating in the project, the consultant's understanding of the project and
approach to the project, and the cost of the project. Based on this evaluation,
Rothberg, Tamuburini and Winsor, Inc. was selected as the lowest and best respondent.
� FINANCIAL IMPACT
Funding for this project will come from the Sewer User Fund. Adequate funds
are available and funding for the project was appropriated in the 2004 budget.

This Appendix is attached to and made a part of the Agreement dated August 12,
2004, between the CITY OF PUEBLO ( "City "), and Rothberg, Tamburini & Winsor,
Inc. ( "Engineer ").
PROJECT SUMMARY
This Appendix to the Agreement covers specific engineering services for the
Groundwater System for the JRD Water Reclamation Facility Project (hereinafter and
in this scope of work referred to as "The Project ").
Engineer shall perform the services defined below which are divided into the
following four (4) phases for the study planning, preliminary design, final design, and
construction of the project to meet the City's budgeting process and to optimize
construction:
Phase 1
— Study and Report Phase
Phase 2
— Preliminary Design
Phase 3
— Final Design/Bidding
Phase 4
— Construction
The first phase of work shall be accomplished with a preferred groundwater system
alternative selected by early November 2004 so that the City may refine the design
and construction cost budget and be ready to proceed with preliminary and final
design and the remainder of the work early in 2005. The RTW team has planned the
work this way so that a minimal amount of study funds shall be expended in 2004 and
the remainder of the work shall be done under future budgets.
The construction activities have been scheduled so that the influence of rising water
in Arkansas River has the lowest impact possible on the installation of whatever
groundwater control system is selected. The project schedule assumes that
construction shall be performed when Arkansas River is at its lowest level.
THE INITIAL SCOPE OF WORK IN THE LETTER AGREEMENT SHALL
INCLUDE ONLY THE PHASE 1 — STUDY AND REPORT PHASE FOR AN
ENGINEERING FEE OF $24,475.
THE SCOPE OF WORK PROPOSED FOR PHASES 2, 3, 4 AND 5 SHALL BE
NEGOTIATED AND INCLUDED IN AN AMENDMENT TO THIS CONTRACT
1L + /IIYO�YaxiJl111i�
PHASE 1 — STUDY AND REPORT PHASE
The RTW team shall prepare a groundwater study and report for the recommended
groundwater dewatering facilities for the Pueblo JRD Water Reclamation Facility
(WRF). The purpose of the study is to identify the potential for groundwater to
damage structures and a means for avoiding such damage. The focus of the plant -
wide dewatering system is to lower groundwater levels temporarily to protect the
secondary clarifiers and other concrete structures susceptible to structural damage by
groundwater when they are emptied, such as during time periods when routine
maintenance is required. Recommendations shall be made that include modifications
to existing structures to make them less susceptible to groundwater damage. The
RTW team shall also identify permits required for the dewatering system, including
recordkeeping and recording requirements.
The RTW team shall evaluate the one (1) existing, permitted well and the four (4)
construction dewatering wells and make recommendations concerning their future use
or removal. The one existing permitted well has a stainless steel casing located in the
middle of the three secondary clarifiers and is approximately 25 to 30 feet deep. The
four (4) other existing dewatering wells with PVC casing are approximately 20 to 25
feet in depth and are located west and north of the existing secondary clarifiers.
Since the four (4) dewatering wells are not functioning, are not permitted, and have
not been used recently, the State of Colorado wants them capped, sealed and
decommissioned. However, the City would prefer keeping them in service, if they
can be used in an overall groundwater control system.
PROJECT MANAGEMENT
The following project management and coordination activities shall be
provided.
Assign and supervise project staff
Monitor the project schedule.
Plan and monitor project work task budgets.
Perform Engineer's project accounting and bookkeeping.
Prepare and submit Engineer's monthly invoices to the City. Engineer
shall provide monthly progress reports with a summary with each
billing that describes the project progress to date, present financial
status, and identify potential problem areas and solutions.
Maintain project files and documentation at the office of the Engineer
7. Execute and coordinate subcontracts with subconsultants.
A kick -off workshop shall be held in late - August 2004 for project planning.
Workshop objectives include reviewing project scope and schedule,
delineating responsibilities and lines of communication, collecting and
reviewing existing data, identifying additional data requirements, and
discussing the concerns and expectations of the City personnel for the first
phase of the project.
After the workshop, the RTW team shall perform a site tour with the City staff
to review the headworks, primary clarifiers, aeration basins, secondary
clarifiers, anaerobic digester building, solids processing building, chlorine
contact basin and any other structures to review evidence of groundwater
damage and potential for damage from groundwater based on a review of the
plant and headworks building construction documents.
The RTW team shall prepare meeting minutes and findings for distribution to
the City staff within seven (7) days of the workshop.
DATA COLLECTION AND FIELD ANALYSIS
Based on information obtained from the City of Pueblo, and our experience
with similar projects, the RTW team shall characterize the hydraulic
conductivity of the subgrade materials through the performance of draw down
testing using the existing temporary construction dewatering wells at the site.
Testing shall be performed using a variable speed pump with a maximum
pump rate on the order of 300 gallons per minute. To accurately record the
change in water levels in adjacent wells, Terracon shall install vented
vibrating wire piezometers in selected wells that shall be connected to
electronic data loggers. The vibrating wire piezometers transmit minute
changes in water pressure and temperature at preprogramed intervals ranging
from about 2 seconds to as long as 5 hours. The changes in water pressure
shall be converted to changes in water levels and compared with the pump
discharge rates to characterize the hydraulic conductivity for use in reviewing
dewatering options.
Subsequent to selection of the chosen groundwater dewatering alternative, the
RTW team shall review the data collected and prepare, if necessary, a
supplemental work plan that may involve additional field - testing or
exploration.
The field investigation and data collection effort shall be accomplished to
determine the following: 1) if the existing dewatering wells are adequate for
use as the dewatering system, 2) if improvements to these wells are needed,
and 3) what pumping capabilities must be provided. Once the characteristics
of the alluvium are established, the need for additional wells shall be assessed.
The RTW team shall also determine the value of converting the existing
permitted dewatering well permanently to a piezometer or using the existing
permitted dewatering well or the four (4) other existing dewatering wells as
part of the comprehensive groundwater system.
10CiN!_chJ/ WA 611!1►[siBlV10
The following data and information shall be reviewed and summarized:
1. History of sediment deposition in and flow records of the Arkansas
River relative to groundwater elevations based on United States
Geological Survey (USGS) studies and other information to determine
whether sediment deposition is a likely cause of significant rise in
water table elevation,
2. Information from available geotechnical reports, logs, groundwater
monitoring well logs from plant and headworks building construction
and other projects,
3. Plant construction and headworks building construction documents to
identify structures and equipment at risk of damage by groundwater,
4. Other easily accessible groundwater information.
This data shall be reviewed for historical trends in groundwater level changes
at the site and geotechnical conditions that may impact potential dewatering
options.
REVIEW REGULATIONS AND IDENTIFY PERMITS
The RTW team shall review the existing groundwater dewatering regulations
and Division 2 permit requirements issued by the Colorado Division of Water
Resources - State Engineer's Office, the Colorado Department of Health and
Environment (CDPHE), City and County of Pueblo, and local authorities
having jurisdiction over groundwater within the project area.
DEVELOP CONCEPTUAL DEWATERING ALTERNATIVES
Upon completion of the data collection, a maximum of three (3) dewatering
system alternatives shall be considered that are compliant with applicable
State regulations:
1. Groundwater level controls through pumping the existing groundwater
wells and install larger pumps.
Groundwater level controls using the existing wells and supplement them
by drilling 5 to 6 additional wells for a total of 10 to 12 wells.
3. Groundwater level controls using a physical groundwater control barrier,
such as a slurry walls, sheet pile walls or cut -off trenches in conjunction
with dewatering wells.
These alternatives represent the range of technical solutions from the simplest
to the most complex. They also represent the range of systems that may have
higher chances for success.
EVALUATE ALTERNATIVES
Capital, operational, and total life cycle costs shall be developed for each
alternative during the feasibility study. The RTW Team shall compare the
following to make a preliminary alternative recommendation:
1. Overall system costs,
2. The complexity of the alternative systems, and
3. The level of protection afforded by the various dewatering
systems.
The preliminary analysis shall take into account the system costs. The
recommendation shall be developed with an eye toward providing an effective
dewatering system that does not require an exceptional operational
commitment or capital investment. While costs are important, the protection
being acquired by making the expenditure must also be adequate.
COMPARE COSTS OF ALTERNATIVES
An opinion of probable construction costs, including equipment, construction
and operating costs shall be prepared.
f�: 717:\ :7��:7�1�11 \:a• /:7�I1 �]�II
The results of the analysis shall be presented in technical report that represents
a design completion level of approximately 30 %. The technical report
shall include the following:
1. Groundwater elevations that pose a risk for primary and
secondary clarifiers when clarifiers are dewatered for
maintenance
2. Recommended modifications to existing clarifiers to reduce the
damage from groundwater, including pressure relief valves or
other alternatives
3. Recommended clarifier protection and groundwater system
improvements,
4. Where and how the recommended facilities shall be located on the
WRF site, and
I
5. What other supporting infrastructure (piping, power supplies, controls,
access etc.) are needed
6. Recommendations for system operation, and
7. Outline specifications to be prepared during the preliminary design
phase.
Fifteen (15) copies of the preliminary report shall be prepared. Fifteen (15)
copies of a preliminary executive summary shall be prepared.
WORKSHOP NO. 2 — REVIEW PRELIMINARY REPORT
Workshop No. 2 shall be held approximately 2 weeks after the preliminary
report has been submitted for City staff review. The City staff comments on
the preliminary report shall be reviewed.
PREPARE FINAL REPORT
The City comments on the preliminary report shall be incorporated. Fifteen
(15) copies and one (1) reproducible copy of the preliminary report shall be
prepared. An executive summary of the final report shall be prepared. Fifteen
(15) copies of the executive summary shall be prepared.
THE FOLLOWING SCOPE OF WORK PROPOSED FOR PHASES 2, 3, 4 AND 5
SHALL BE NEGOTIATED AND INCLUDED IN AN AMENDMENT TO THIS
CONTRACT WITH THE CITY.
PHASE 2 - PRELIMINARY DESIGN
After the first phase is complete, the RTW team anticipates a 6 to 8 week period
before Phase 2 begins. During this time, the City may wish to review the preliminary
design memo in greater detail and ask questions of the design team. Once the second
phase begins in early 2005, the RTW team shall update the design memo and refine
the recommended layout. This update shall be used as the basis for the "high -
production" efforts of the detailed design phase. Detailed design shall encompass
plans and specifications for the recommended improvements.
The design documents shall include the following:
1. Design assumptions,
2. Dewatering well number and locations,
3. Well diameters and depths,
4. Pump specifications,
5. Well head protection including concrete pad, grouting, and provision of
water table elevation measurement,
6. Discharge piping,
6
7. Electric service including local panel- mounted starter /disconnect,
8. Flow metering,
9. Groundwater treatment systems,
10. Structural improvements, if any,
11. Extensions of existing support utilities, and
12. A groundwater level monitoring system.
An update of the opinion of probable construction costs, including equipment,
construction and operating costs shall be made at the completion of this effort. The
RTW team shall also evaluate the need to rehabilitate the existing permitted and other
wells to ensure that the well casing, electric service, flow meter, wellhead protection,
and permit meets current requirements. The RTW team shall also evaluate the
usability of other City existing equipment, such as submersible and vertical turbine
pumps, in a groundwater management system.
The RTW team shall prepare bid documents for use in soliciting competitive bids
from qualified contractors. The RTW team shall also discuss the various
procurement options with the City. RTW has had good success recently using a
prequalification process for developing a list of qualified contractors. This results in
competitive bids with less risk of receiving low bids from under- or unqualified
contractors. The RTW team suggests the City consider this option in selecting a
construction contractor.
Any changes in the design shall be presented in an amendment to the design
memorandum. This shall be used to support permit applications for dewatering well
construction and discharge of the water back into the environment. Permit
applications shall be made so that when the project design is completed, the work
shall be ready to proceed immediately.
PHASE 3 - FINAL DESIGN /BIDDING
Final design represents the effort to move from an 80% level of completion to a set of
bidding documents. Final details shall be added, particularly in the area of electrical
and instrumentation. Bid documents shall be completed based on the City's
procurement requirements and supporting technical specifications. A final estimate
of probable construction cost shall be prepared. The RTW Team shall meet to review
the completed package with the City and to firmly establish the bidding schedule.
The RTW team have developed this work plan under the assumption the City shall be
primarily responsible for the bidding efforts (document distribution, coordination
with bidders, scheduling, issuing addenda, etc.). The RTW Team shall be available to
respond to technical questions and to prepare responses to these questions that can be
incorporated into an addendum.
Upon receipt of bids, the RTW team shall review the bids and prepare a
memorandum, recommending award. If prequalification is used, this is typically a
short, relatively expedient process.

The work schedule has been developed to allow construction in spring of 2005. The
RTW team anticipates a construction period of 8 to 10 weeks. Our level of effort
includes review of shop drawings for a dewatering system consisting of new pumps
in the existing wells and piping to manage the water discharge. The RTW team also
has planned for mechanical and electrical submittals for the new pumping equipment.
For the purposes of budgeting and estimating a level of effort, the RTW team have
assumed the city shall perform day -to -day inspections and that staff from the
Terracon Pueblo and RTW Denver offices shall be on -site periodically to observe
construction. The RTW team shall review pay applications and requests for change
orders and make recommendations to the City. During construction, the RTW team
shall update the City's operations and maintenance manual to incorporate new
standard operating procedures for the dewatering system.
When construction has reached substantial completion and the dewatering system is
ready to undergo testing, the RTW team shall visit the site and observe initial
operations.
Once the system operation has been demonstrated, the RTW team shall finalize the
standard operating procedures. The RTW team shall prepare an Operation and
Maintenance Manual that shall include the following standard operating procedures
and information:
1. Dewatering procedures,
2. Equipment maintenance,
3. Operating and Maintenance instructions for the system and the flow
meters,
4. Develop procedures for taking piezometer readings prior to dewatering
tanks,
5. Prepare operating safety procedures to avoid groundwater damage to
structures
6. Prepare written operating instructions for implementing selected
procedures
Based on the actual construction conditions, as- constructed drawings including
existing wells, if used, and all new wells and equipment shall be developed. When
construction is complete, including site restoration and clean up, a final inspection
shall be made and a certificate of final completion issued.
Permits from the Division 2 Water Engineer for well operation, and from the
Colorado Department of Public Health and the Environment (CDPHE) for
groundwater discharge, applied for in Phase 2 of the project, shall be acquired.
