Mountain Waterworks
TASK ORDER NO. 11081.a
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 November 2019 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 1d) between the above
mentioned parties dated October 1, 2017. The Project Name for this Task Order is as
follows:
WELL 17 WATER TREATMENT FACILITY – DESIGN
PROJECT UNDERSTANDING
The City of Meridian’s (City) domestic water system experiences water quality issues
related to the precipitation of iron and manganese from groundwater resulting in brown
water events, reduced chlorine residuals, extended system flushing, and customer
complaints. The purpose of this project is to investigate feasible treatment options and
implement the preferred water treatment technology at Well 17 located on the corner of
Locust Grove and Time Zone Drive. The City intends to have the existing structure
demolished and construct a new well house/treatment facility including a greensand (or
similar technology) system for their approximately 1,000 gallon per minute (GPM) Well
17.
The project will consist of:
(1) Establishing iron and manganese removal criteria at Well 17.
(2) Completing final design and preparing specifications for the procurement of an
iron and manganese removal system from an equipment supplier using a
competitive procurement process.
Completing final design and preparing a construction document package for City’s use
in obtaining bids for the construction and installation of the previously procured
equipment.
SCOPE OF WORK
Mountain Waterworks will perform the following tasks for the iron and manganese
removal project at Well 17.
Meridian City Council Meeting Agenda November 26, 2019 – Page 224 of 352
Task Order 11081.a Well 17 Water Treatment Facility – Design Page 2 of 14
Mountain Waterworks
Task 1 – Project Management and Administration
Mountain Waterworks will provide the overall project planning, management, scheduling,
coordination of efforts and the day-to-day administrative tasks required for this Task
Order. The project is assumed to require eight months for the water treatment equipment
procurement and design of the water treatment facility. Mountain Waterworks will prepare
written monthly progress reports. The reports will include the following items:
• A written description of the progress of the work accomplished to date.
• A summary of project issues and concerns that need to be resolved.
• A summary of changes in contract amount or time (if applicable).
• Monthly invoices for work completed.
Deliverables
• Monthly progress reports and detailed invoices
Task 2 – Pilot Test
Mountain Waterworks will perform a pilot test at Well 17 for up to five (5) days to determine
the recommended conditions for iron and manganese removal. Processes currently
expected to be tested include:
• Greensand media filtration
• Pyrolusite media filtration
The pilot test will consist of two columns for testing, one for each process, at varying
loading rates to establish filter performance criteria. Field tests on the raw water and
filter effluent are expected to include the following:
Field Testing Parameter Frequency
Manganese 60 minutes (or as defined in the pilot plan)
Iron, Total 60 minutes (or as defined in the pilot plan)
Ammonia Twice Daily
Hydrogen Sulfide Daily
Chlorine Solution Strength Daily or more frequently if necessary
Free/Total Chlorine Daily or more frequently if necessary
Alkalinity Daily
pH 60 minutes (or as defined in the pilot plan)
Free Chlorine Residual 60 minutes (or as defined in the pilot plan)
Mountain Waterworks will coordinate with the City to determine desired free chlorine
residual after filter and monitor dosing to achieve it to the extent possible. Mountain
Waterworks will assist the City in conducting a taste test of the water produced during
various pilot test setups.
Report
Meridian City Council Meeting Agenda November 26, 2019 – Page 225 of 352
Task Order 11081.a Well 17 Water Treatment Facility – Design Page 3 of 14
Mountain Waterworks
Data produced from the pilot testing will be analyzed to determine the efficacy and
efficiency of the tested filter media for iron and manganese removal at varying loading
rates. The analysis will also estimate required chlorine dose.
Mountain Waterworks will prepare a draft Well 17 Pilot Study Report containing the results
of the pilot test and analysis. The report will include an evaluation of the tested media
and treatment processes for full scale use at Well 17 and will serve as a basis of design.
After meeting with the City to review the draft report, Mountain Waterworks will prepare a
final Well 17 Pilot Study Report incorporating pertinent revisions. Although likely not
required by IDEQ, the final report will be provided to IDEQ as an attachment to the
Preliminary Engineering Report (Task 7).
Deliverables
• Draft and final Well 17 Pilot Study Report
Task 3 – Public Meeting and Zoning Requirements (if necessary)
Mountain Waterworks will assist the City in obtaining a certificate of zoning compliance.

requirements, Mountain Waterworks will assist the City in obtaining a variance. Mountain
Waterworks will specifically provide the following:
• Certificate of Zoning Compliance – Mountain Waterworks will prepare submittal
package per Planning Department requirements for obtaining a certificate of
zoning compliance. A preliminary landscaping plan, site plan, and building
elevations will be included for zoning compliance and approval.
