Task Order No. 10055 with CH2M Hill Engineers, Inc. for WWTP UV Disinfection System Expansion Phase 1 DesisgnPursuant to the
MASTER AGREEMENT FOR PROFESSIONAL SERVICES
BETWEEN
This Task Order is made this 22nd day of April, 2014 and entered into by and between the City
of Meridian, a municipal corporation organized under the laws of the State of Idaho, hereinafter
referred to as "City", and accepted by CH2M Hill Engineers, Inc., hereinafter referred to as
"Engineer" pursuant to the mutual promises, covenant and conditions contained in the Master
Agreement (Category 2A) between the above mentioned parties dated December 6, 2011.
The Project Name for this Task Order 10055 is as follows:
Disinfection of the filtered wastewater is required to destroy microorganisms to levels less than
the NPDES permit limit prior to discharging to the outfalls. The current NPDES permit has the
following fecal coliform bacteria effluent limitations for both the Five Mile Creek and Boise
River outfalls:
• Average Monthly— 100/100 ml
® Average Weekly — 200/100 ml
• Daily Maximum —800/100 ml
The existing plant disinfection system consists of two Ultraviolet (UV) channels, each
containing a Trojan UVTM 3000 horizontal system consisting of three banks. Each bank
contains 17 modules and each module contains 8 lamps. Each bank has a capacity of 2.5
mgd. The UV channels are configured to operate in parallel. The total capacity (all six banks
operating) is 15 mgd peak hour (PH). The firm capacity (five banks operating and one offline)
is 12.5 mgd (PH). The equivalent maximum month values are 8.3 mgd (total capacity) and 6.9
mgd (firm capacity).
For UV disinfection systems, the following reliability and redundancy requirements apply:
EPA — must have 50% capacity with the largest basin out of service (multiple units
required)
Task Order 10055 Wastewater Treatment Plant — UV Disinfection System Expansion Phase 1 Design Page 1 of 20
CH21NIHILL Engineers, Inc.
® IDEQ — a minimum of two channels with two UV banks per channel
The existing UV system meets redundancy and reliability requirements but represents the unit
process with the lowest firm capacity. The UV system will need to be expanded to
accommodate future flow and load conditions as the City grows.
Additional UV capacity is also needed to simplify the maintenance of the UV system. Even
though the UV system has two channels, operation with one channel out of service during
peak flows is a significant challenge. By increasing the UV system capacity, plant staff will
have the ability to adequately treat peak flows through one channel while allowing the other
channel to be shut down for maintenance activities. The increased disinfection capacity
provided by this enhancement will ensure that the required UV dose can be delivered while
maintaining compliance with the NPDES permit requirements.
The project will include the design of a building to enclose the ultraviolet disinfection system to
provide protection for the expensive ultraviolet disinfection equipment and protection from
freezing temperatures.
The building will provide greater protection from extreme temperatures and will likely increase
the life of the disinfection system and reduce operation and maintenance costs. It can be
heated to keep the temperatures above freezing and provides a dry environment for the
equipment. The building will be architecturally similar to the Tertiary Filters Building.
ENGINEER will follow a traditional step -wise, phased approach to performing the work
associated with design of the UV system. The following tasks will be performed and are more
fully described in the Scope of Work section below:
® Project Definition and Alternatives Evaluation — identify target capacity and redundancy
goals, develop alternatives, assist City with selecting preferred alternative to advance to
design
• Preliminary Engineering and Design (30 Percent Design)
• Equipment Procurement — assist City with procurement of UV disinfection equipment
upon which to base facility design details
• Design Development Documents (60 Percent Design)
® Final Design Documents (90 Percent Design)
® Bid -Ready Documents (100 Percent Design)
® Bid Period Services — assist City with bid process for selecting a general construction
contractor

16. Submission of sealed plans, technical specifications, and other support documents as
required by required by Section 420 of IDAPA 58.01.16 -Wastewater Rules will occur as
part of the completion of construction contract.
17. The drawings will follow CH2M HILL CAE/CAD standards. Microstation will be used to
develop the drawings. The drawings will be converted to the current version of AutoCAD
and provided to the City as project record drawings following construction.
18. Contract document drawings will be produced at ANSI D size (22- by 34 -inch), but
drawings for interim design review submittals will be reproduced at half size (11- by 17 -
inch). Standard design details for the project will be produced in 8 Y2- by 11 -inch format.
19. The City will be responsible for document reproduction services. ENGINEER has not
included budget to cover the expense of reproduction costs for any of the work products
and/or deliverables denoted in this Task Order.
20, Any Cost opinions or project economic evaluations provided by ENGINEER will be on the
basis of experience and judgment, but because ENGINEER has no control over market
conditions or bidding procedures, ENGINEER cannot warrant that the bids, ultimate
construction cost, or project economics will not vary from these opinions.
21. The City has been collecting UV transmittance (UVT) data since the start-up of the
existing UV system. This data set will be sufficient to validate or revise the original UVT
design criteria for the expanded system.

Civil/Geotechnical
1. Demolition of the existing UV System Building will be accomplished as part of this
contract. No salvaging or relocation of materials and equipment is required.
2. Legal, easement or plat surveys of the existing site will not be required.
3. Civil sitework plans will be provided only for areas of the site involving significant
disturbance to existing grading.
4. Site drawings will only be prepared for those sectors in the plant where new facilities are
to be constructed.
5. Landscaping is not required. Unpaved areas will be covered with river rock to restore to a
condition similar to existing.
6. No new roadway work is required. Existing roadways impacted by construction will be
shown to be restored to similar alignments, widths, and slopes as exist prior to
construction.
7. Geotechnical engineering design criteria will be based on review of historical geotechnical
investigation reports that have been prepared for previous WWTP projects in close
proximity to this project. The City will provide hardcopies and/or digital copies (Word or
PDF format) of historical geotechnical investigations performed for previous WWTP
projects for use by ENGINEER geotechnical engineering staff to prepare design criteria
for this project. It is assumed that the conditions are known to an adequate depth to
make estimates of settlement and bearing resistance. Subsurface geotechnical
exploration(s) will not be performed as part of this project.
Structural/Architectural/Geotechnical
1. Conventional spread foundations will be required for all new facilities. Over excavation,
preload, piles, or underdrain systems are not required.
2. Uplift due to high groundwater levels, if any, will be addressed with thickened base slabs
or pressure relief valves in slabs. No underdrain systems or tension systems will be
required.
3. Building architecture (materials, construction) of all new facilities will be similar to existing
structures (e.g. Tertiary Filters Building).
4. Building sprinkler systems are not required for the new building.
5. The UV Building will not be designed to be ADA compliant.
Process Mechanical
Only hydraulic assessments required for design of the new or modified facilities are
included. A partial hydraulic profile drawing from the receiving stream to just upstream of
the UV system will be provided.

2. Design concerning "plant -wide" utility systems such as basin drainage, water, and in -plant
waste collection/disposal will be limited to extensions and/or changes in existing piping.
No new structures or equipment will be needed.
3. No corrosion control provisions will be required other than materials selection and
coatings.
4. An odor control system will not be provided.
HVAC and Plumbing
Performance specifications will be used for all HVAC and plumbing systems requiring
detailed design by the contractor and vendor.
1. The new instrumentation and control system will be based on the use of programmable
logic controllers. The process instrumentation, control systems and SCADA integration
will be compatible with existing plant systems. 1&C system design scope includes only
control system design for the new facilities and modifications to the existing system to
allow incorporating the new facilities.
2. ENGINEER will not perform the work of developing process control system software for
both the PLC and the PC interface as part of this Scope of Work. This work may be
added to the scope as part of services during construction.
3. Electrical design will include design to provide power to new equipment and facilities and
lighting for new facilities and areas of the site. Performance specifications will be used for
interior lighting requiring detailed design by the contractor and vendor.
4. The existing secondary or emergency electrical power supply system is adequate to
handle any new loads. No additional secondary or emergency power source will be
provided.
The following schedule is based on a Notice to Proceed (NTP) from the City by April 2014 and
resulting in Final Design being completed by May 2015, An NTP issued on a different date will
change the schedule accordingly.
