REQUEST FOR QUALIFICATIONS (RFQ) FOR ENGINEERING FIRMS INTERESTED IN WORKING WITH THE CITY TO INVESTIGATE AND RECOMMEND IMPROVEMENTS TO KEY WATER SUPPLY AND DISTRIBUTION FACILITIES

Description

The City of Pleasanton (City) is issuing a Request for Qualifications (RFQ) to engineering firms interested in working with the City to investigate and make recommendations for how to address periodic nitrification in the treated water system, particularly at or near the Foothill Storage Tank. In addition, the City operates groundwater facilities to supplement treated water from the Zone 7 Water Agency (Zone 7). An assessment is needed of Well 8 for both infrastructure (building, equipment, controls) as well as operational practices, particularly chemical selection and dosing systems. Since these scopes are separate and distinct, the City requests that interested firms provide unique teams and approaches addressing each area of need separately in one composite Statement of Qualifications (SOQ). The City will decide if one or more contracts are needed after SOQ¡¯s have been submitted and evaluated.

REQUEST FOR QUALIFICATIONS (RFQ)
FOR ENGINEERING FIRMS INTERESTED IN WORKING WITH THE
CITY TO INVESTIGATE AND RECOMMEND IMPROVEMENTS TO KEY
WATER SUPPLY AND DISTRIBUTION FACILITIES
I. INTRODUCTION
The City of Pleasanton (City) is issuing a Request for Qualifications (RFQ) to
engineering firms interested in working with the City to investigate and make
recommendations for how to address periodic nitrification in the treated water
system, particularly at or near the Foothill Storage Tank. In addition, the City
operates groundwater facilities to supplement treated water from the Zone 7
Water Agency (Zone 7). An assessment is needed of Well 8 for both
infrastructure (building, equipment, controls) as well as operational practices,
particularly chemical selection and dosing systems.
Since these scopes are separate and distinct, the City requests that interested
firms provide unique teams and approaches addressing each area of need
separately in one composite Statement of Qualifications (SOQ). The City will
decide if one or more contracts are needed after SOQ’s have been submitted
and evaluated.
II. BACKGROUND, PROBLEM STATEMENT, AND INVESTIGATION TOPICS
The City’s water supply includes groundwater from city-operated wells, and
treated surface and groundwater purchased from Zone 7. Approximately 20
percent of customer demand is met by the City’s groundwater resources. The
rated capacity of Well 8 is 3,650 gallons per minute. Well 8 and the associated
facilities are located at the City’s Operation Services Department’s (OSD)
Corporation Yard at 3333 Busch Road. The City’s water distribution system
includes 21 storage reservoirs, 15 pump stations, 17 pressure reducing stations
and over 330 miles of transmission and distribution pipeline. Foothill Reservoir is
the largest tank in the distribution system, serving the lower pressure zone. It is
constructed of concrete, 213 feet in diameter, with a nominal capacity of 8 million
gallons.
A. Nitrification Evaluation
The City’s distribution system currently experiences nitrification issues during the
summer months. See Exhibit A for a graphical overview of the water distribution
system and Exhibit B for sampling locations, including those that historically have
had higher frequencies and/or values of nitrite. The primary areas of nitrification
1
occur in the northwest portion of the water system around the Foothill Tank, and
its local service area. Based on limited testing, it is suspected in this area, water
from Zone 7 occasionally has high levels of free ammonia (especially at times
when Zone 7 supply consists of groundwater blended in with surface water). It is
believed that this free ammonia, in combination with water aging at the Foothill
Tank, is the main cause for the nitrification issues in the area. The OSD currently
manages nitrification issues in the system with aggressive tank fill-and-drain
cycles at the Foothill Tank as well as other tanks throughout the system.
Although this strategy is effective most of the time, the OSD must still fully drain
the Foothill Tank on certain occasions because of continued nitrification issues.
In addition, aggressive tank cycling involves a significant amount of operator time
to manage, requires coordination with available emergency and fire storage, and
causes varying system operating pressures. The main objectives of this task are
to recommend improvements that will (1) allow the OSD to reduce the
aggressiveness of the fill and drain cycles while reducing nitrite issues in the
Foothill Tank area; and (2) evaluate the potential for nitrification in other areas of
the distribution system and recommend improvements to address, if needed. At
minimum, the Consultant could provide guidance on the sampling plan and
guidance of whether nitrification problem areas have moved beyond Foothill and
strategies to address. More detail is provided in Exhibit D: Preliminary Scope of
Work.
B. Well 8 Assessment and Chemical Systems Evaluation
Well 8 is located at the OSD and is one of three groundwater well facilities the
City operates to supply water in addition to water purchased from Zone 7. The
facilities include a 3,650 gpm groundwater pump, fluoride dosing system, and
chloramine dosing system. See Exhibit C for an aerial of the facilities, photos of
existing equipment, process schematic and list of major assets. Although some
equipment modifications and replacements have been performed in the years
since its construction, no facility-wide assessment has been performed (except
for the pump/motor and well casing which have been recently replaced and/or
rehabilitated). There are two equally important objectives of this Task. The first is
to assess the Well 8 facilities, recommend improvements to improve its operation
and extend its useful life, and prepare a basis of design summary so the
improvements can be implemented as a future design and construction project.
Final design (contract documents) is not included in this scope of work. More
detail is provided in Exhibit D: Preliminary Scope of Work. The second equally
important objective is to assess the existing chemical dosing systems and
evaluate applicable alternatives for type of chemical used, storage, handling, and
dosing and control systems, at minimum. The Consultant should take a global
approach with the recommendations made for chemical systems in that they
should be applicable as future upgrades at other well sites.

IV. SCOPE OF WORK/SCHEDULE OF DELIVERABLES
The final scope of work will be developed in consultation with the selected
consultant(s). In general it shall address and/or provide a deliverable for the
following:
Nitrification Evaluation
An independent review and report of all data (Exhibit E) provided to the
Consultant by the City to determine system locations of current and future hot
spots for nitrification. The Technical Memorandum (TM) shall be provided to the
City within five weeks of Notice to Proceed (NTP).
Evaluation of new systems, including residual control and mixing systems,
capable of controlling nitrification, commensurate with evaluation criteria (at
minimum) described in Section II.A, for the Foothill Tank and other locations
throughout the distribution system as identified by the Consultant. For purposes
of procurement of pilot test equipment/system, the Consultant shall provide a
written recommendation to the City of the preferred system by May 1, 2019. This
deadline is imperative as the City intends to pilot test during the summer of 2019,
and needs a minimum of two months for procurement and delivery of pilot test
equipment. The Final TM shall be submitted to the City by June 3, 2019.
Specialty assistance with pilot testing, see Exhibit D for specialty skills and
expertise which may be required. This is an optional service, and will depend
upon successful procurement of pilot test equipment. The City will provide staff
who will operate pilot test facilities.
After completion of pilot testing, submit a Final Nitrification Report which
summarizes all research, investigations, findings and recommendations under
this task.
