Floridan Wellfield Assessment and Improvements
PROJECT UNDERSTANDING
Raw water is the lifeblood and the main source of water of the Oslo water treatment
facilities (WTP) and Hobart water treatment facilities (WTP). With recent and more
frequent wellpump motor failures at the Hobart water treatment plant, limitations
in the South WTP wellfield controls and RTU system, and on-going wellfield
improvements at the South Oslo road water treatment facilities, it is prudent to
improve the sustainability and reliability of these wells.
The purpose of this project is to improve the sustainability and reliability of the
wellfields and implement a plan to standardize equipment and operations of wells,
improve reliability of the wellfields, and provide upgrades to the fiber optic and
controls system for the wellfields. Standardizing equipment and operations will
allow interchangeability of equipment among all of the wells, resulting in a more
x
robust wellfield system.
'4 SCOPE OF WORK
A thorough evaluation of the existing wellfield performances with respect to
mechanical efficiency, specific capacity and performance, and electrical conditions
will be provided.
TASK 1- WELL PERFORMANCE - FIELD TESTING
Consultant will conduct well testing, collect field data, and update well
performance data collected in December 2013.
Consultant will perform wellfield testing of fourteen (14) wells in the North and
South wellfields (the new well S7 and S4 will not be included) which will consist of
water quality parameter testing: sand, silt density index (SDI), turbidity, hydrogen
sulfide, iron, pH, dissolved oxygen, and specific conductance; specific capacity
testing, review of SCADA system logger data, static and pumping water levels,
pumping rates, and specific capacity.
FAUtilities\UTILITY - Engineering\WATER\Wells\Admin\IRCU Floridan Well Improvements 1.29.18.docx Page I ofd
Consultant assumes instruments (flow, pressure, drawdown) are calibrated and
functioning at the time of field testing and that all wells and wellpumps are in
operation.
Consultant will prepare a technical memorandum of the field test results for IRCU
staff review and attend one meeting to discuss findings. Consultant will update the
existing table of well performance and prepare a graph depicting wellfield
performance trends. Consultant will provide recommendations which may
improve or enhance individual well performance.
Consultant will prepare table summarizing all the information and data collected
for each of the wells.
TASK 2 - EVALUATE EXISTING WELLS and CONDUCT ASSESSMENT
CONSULTANT will attend a kick-off meeting to discuss the information and data
collected on each of the wells to date and the current operational issues at each
wellfield. Information on the individual performance of each well will be
discussed.
CONSULTANT will conduct a 1 to 2 -day walkthrough of each of the wellsites (14
total) concurrently with the field testing in Task 1, in order to assess current
condition of each wellhead. CONSULTANT will prepare condition assessment
summary, performance testing, wire/water efficiency data, and specific capacity
performance.
Consultant will develop a raw water hydraulic model for both water treatment
plants using WaterGEMS, specific capacity with intent to install wells on several
wells
Consultant will review well pump control operations with respect to motor failures
which have occurred more frequently than normal.
CONSULTANT will evaluate all of the existing wellpump capacities, pump curves
and motors with respect to manufacturer, performance, pump selection, material,
hardware used at each well, and inventory of spare pumps.
FAUtiliticAUTILITY - Engineering\WATER\Wells\Admin\IRCU Floridan Well Improvements 1,29.18.docx Page 2 of 7
Consultant will help define spare parts inventory needed to improve wellfield
reliability.
CONSULTANT will develop a table which outlines the specific requirements and
information on each of the wells, wellpumps, and motors.
CONSULTANT will evaluate standby generator capability and potential limitations
of existing standby power capacity.
CONSULTANT will evaluate the applicability of variable frequency drives (VFD's)
at the wells which may warrant installation of VFD's. The evaluation will consider
return on investment (ROI) and the additional maintenance and replacement costs
which can be inherent with VFD installation at wells.
Consultant will review existing raw water quality data with respect to the design
water quality used for membrane selection. Consultant will provide
recommendation of impacts to treatment plant or if further and additional raw
water quality analysis is necessary.
TASK 3 - SCADA SYSTEM and FIBER SYSTEM EVALUATION - WELLS
It is recommended to continue with the PLC upgrade project described in the Final
Report - Water Plant SCADA Improvements Evaluation, May 2015, and work
completed in early 2016 (Refer to attached report schedule). The existing PLC and
control system is antiquated, has been discontinued, replacements are difficult and
costly to acquire, and Allen-Bradley has discontinued manufacturing and support
of the PLC5 hardware, which comprises the majority of the hardware at both water
plants. The completed system would provide all of the advantages noted
previously and also allow for any future changes to well sequencing. This will also
allow further well upgrades without installing additional CPU's at additional cost
at each of the wells.
Consultant will review fiber optic (FO) system, and identify final improvements to
complete the FO system to all wells at both water treatment plants. Consultant will
review previous construction documents and record drawings, provide field
investigations of each wellsite, and verify existing equipment at each well.
Consultant will review and identify individual well improvements to integrate FO
at each well and develop a summary of improvements that can be designed for
FAUtilities\UTILITY - Engineering\WATER\Wells\Admin\IRCU Floridan Well Improvements 1.29.18.docx Page 3 of 7
implementation. Consultant will investigate the conversion of Hobart well panels
to strictly remote I/O versus the existing PLC CPU and I/O at each well and
provide a summary of recommentions.
Consultant will review the SCADA system programming and develop an
automated wellfield matrix for each water plant. The current operation at Hobart
wellfield includes manipulation of discharge check valve to potentially be closed
during pump startup, therefore modification of this operation will be evaluated.
TASK 4 - PREPARE TECHNICAL REPORT AND DESIGN GUIDELINES
Consultant will prepare report on findings, recommendations, costs, summary of
individual well improvements, auxiliary power requirements.
Consultant will prepare design guidelines for the improvements at each well,
including sketches, costs, and list of improvements. Design of these improvements
(VFD's, FO, auxiliary power if needed) is not included in this scope, but can be
provided as additional services.
CONSULTANT will finalize summary report after review meeting and furnish up
to six (6) copies of report, including electronic in PDF format.
Consultant will attend a coordination meeting to discuss the report on the findings.
