TASK ORDER NO. 11146
Pursuant to the
MASTER AGREEMENT FOR PROFESSIONAL SERVICES
BETWEEN
CITY OF MERIDIAN (OWNER) AND MOUNTAIN WATERWORKS, INC (ENGINEER)
This Task Order is made this ___ day of January 2020 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 MOUNTAIN WATERWORKS,
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 October 1, 2017. The Project Name for this Task Order is as
follows:
WRRF Dissolved Air Floatation Thickners (DAFT)
System Upgrades
PROJECT UNDERSTANDING
The Engineer’s scope of services, time of completion and compensation shall be as set
forth herein. This Task Order is for professional engineering services to design
improvements identified and selected by the City as part of the WRRF Capacity and
Optimization Study report prepared by the Engineer.
SCOPE OF WORK
The City has two existing DAFTs at the WRRF that thicken waste activated sludge
(WAS) prior to anaerobic digestion. Due to growth in the community and associated
increase in wastewater volume, the DAFT system is currently operating at redundant
capacity (maximum capacity with 1 unit out of service). The DAFTs will be integrated
and utilized for thickening WAS from the liquid expansion project, which may further
increase WAS production. Therefore, the City has determined the capacity and
efficiency of the DAFT system needs to be increased in the near future. In addition to
DAFT capacity upgrades, new polymer feed skids (one for each DAFT) and VFD
installation on the existing clarifier scum pumps are included within this scope of work.
Because the capacity of the DAFT system is being increased, the Idaho Department of
Environmental Quality (IDEQ) will need to review and approve a project Preliminary
Engineering Report (PER) along with the final design Plans and Specifications. The
27th

Task Order 11146 WRRF DAFT Capacity Upgrades Page 2 of 4
Mountain Waterworks, Inc.
WRRF Capacity and Optimization Study report will serve as the basis for the project
PER. Specific project tasks include the following:
Task 1 – Project Management
Coordinate with the project team and City throughout the project related to schedule,
budget, and status updates. Meeting minutes will be prepared for project coordination
meetings and distributed to attendees. Monthly progress reports will be prepared and
submitted with monthly invoices to document project progress. Each monthly progress
report and invoice will include a percent complete estimate for the project.
Deliverables
• Monthly progress reports with invoices
• Meeting minutes
Task 2 – Preliminary Design
A project PER will be prepared along with 30% design drawings during the preliminary
design phase. The PER will describe the project approach to demo the existing facilities
while keeping the overall system in operation. Design criteria for the DAFTs, pumping
systems, and polymer feed skids will be developed and documented. The 30% design
drawings will include plan sheets for each system being upgraded and a detailed P&ID
to describe system operation and controls.
The PER and 30% design will describe improvements for:
• DAFT 1 and DAFT 2 mechanical equipment replacement
• DAFT 1 and DAFT 2 EDUR pump replacement and upsizing. It is anticipated a
second parallel EDUR pump will be required at each DAFT
• Scum pump VFD installation for secondary clarifiers 3, 4, and 5
• Polymer feed skid installation for DAFT 1 and DAFT 2
o The polymer feed skids are anticipated to be installed within the existing
Mechanical Building
Deliverables
• Draft and final PER for City review and submittal to IDEQ for review and approval
• 30% design documents for City review
Task 3 – Final Design
Following preliminary design, engineer will develop final design plans and specifications
for construction bidding. The design will incorporate mechanical, electrical, and
instrumentation needs for the project. The bid documents will include the following
components:
• DAFT 1 and DAFT 2 demolition requirements
• DAFT 1 and DAFT 2 mechanical equipment replacement
• DAFT 1 and DAFT 2 EDUR pump replacement and upsizing
• Scum pump VFD installation for secondary clarifiers 3, 4, and 5.
