WA'T'ER TREATMENT PLANT PROJECT
PURPOSE
The purpose of this Task Order is to evaluate the performance of the Yakima Water
Treatment Plant (WTP).
ENGINEER'S SERVICES
The following tasks and subtasks for completing the project are described below.
TASK I - OPERATIONAL AUDIT
The Operational Audit work tasks focus on a series of evaluations and investigations that
will yield recommendations for assessing the capability of the existing facilities to meet
current and anticipated regulations, City water quality goals, and for optimizing the
operation of the existing WTP. The Audit will be completed in the six work subtasks
described below. Two meetings and/or workshops with City Staff are proposed during
the project. The product of the Operational Audit will be a written report detailing the
modifications and recommendations which result from the regulatory and on-site
investigations.
Subtask I.1- Regulatory Analysis
The purpose of this task is to provide an overview and critical assessment of regulatory
issues pertaining to the Safe Drinking Water Act (SDWA). Raw and finished water
quality data will be collected and analyzed for compliance with the SDWA and its recent
amendments. An overview of proposed and future drinking water regulations will be
prepared pertaining to the WTP and water quality. The following specific activities will
be conducted as part of this task:
I.1.1 Prepare an overview of the SDWA and its amendments.
1141.76 W 1 vnlnror 1lrivn Cnitw Inn • Rnicr+ IB RZ71 A • l7AR\ 114-1/RR • FAY 1111R1 176_99¢1
1.1.2 Collect and review available raw and finished water quality data to ascertain
WTP performance.
1.1.3 Determine compliance of the W I'P with the following existing rules:
• Surface Water Treatment Rule
• Trihalomethane Rule
A summary table will be prepared listing each final rule and compliance status of
the WTP.
I.1.4 Prepare an overview of proposed and future regulations and rules which will have
direct impact on the WTP including: Disinfectant/Disinfection By-products Rule
(D/DBP), Interim and Enhanced Surface Water Treatment Rules, Filter Backwash
Recycling Rule, Arsenic Rule, Sulfate Rule, and the Ground Water Disinfection
Rule.
Subtask L2 - Pretreatment Performance Evaluation
The objective of this task is to review and evaluate the current pretreatment processes at
the WTP. Bench scale treatability tests will be performed to optimize the present
chemical addition and clarification processes and to evaluate the potential of other
improvements to the current treatment process train. Specific subtasks are described
below:
1.2.1 Meet with key plant operations staff to discuss and review present pretreatment
and chemical dosing strategies.
1.2.2 Review historical raw and treated water quality completed during Task I.1.
1,2.3 Conduct a bench -scale treatability study to optimize the type of coagulant,
coagulant dosage, and the effectiveness of polymer addition.
I.2.4 Conduct filterability tests for the settled water obtained from the bench -scale jar
testing to indicate the relative effectiveness among several pretreatment
alternatives.
I.2.5 Review and comment on the present chemical application sequence. Suggest
modifications to optimize plant performance.
1.2.6 Review and discuss the advantages and issues associated with implementing
improvements to the existing treatment train, such as an alternate flash mix
system, flocculation, and sedimentation.
1.2.7 Compare the benefits of contact filtration, direct filtration, and conventional
treatment in terms of performance and regulatory compliance.
Subtask I.3 - Filtration Evaluation
The objective of this task is to evaluate and report on the condition of the filters at the
WTP using core testing, bench scale, and desktop evaluation techniques to assess the
adequacy of the existing facilities to produce a high quality filtered water. The
evaluation will assess the existing filter performance and recommend methods to
improve filter performance through plant modifications or changes in operational
practice. Specific subtasks to be conducted during the filter evaluation include:
I.3.1 Meet with key operations staff to discuss and receive input about WTP operation
procedures. Collect and review selected as -built plans for the WTP. Copies of
selected plan sheets will be provided by the City.
I.3.1 Supply WTP staff with a brief memorandum describing filter evaluation
techniques, tasks to be performed by WTP staff prior to coring (e.g. recording of:
chemical dose, headloss, filter run time, etc.), and any equipment which may be
needed on-site.
I.3.3 Measure filter media surface elevations at various locations in one representative
filter box.
I.3.4 Perform filter coring of one representative filter to determine the following
parameters:
• floc retention profiles through the filter beds
• media specifications (depth, gradation, standard sieve analysis)
1.3.5 Evaluate backwash suitability including preparation of a backwash turbidity
profile, evaluation of fluidization rates, trough elevation and spacing, and
backwash water supply and disposal adequacy.
I.3.6 Using existing data, assess adequacy of pretreatment for filtration.
I.3.7 Using particle counting equipment, perform analyses of raw and filtered water
and determine log removals through the filters.
I.3.8 Using data collected in foregoing tasks, assess filter characteristics including
mud ball density, support gravel integrity, and underdrain condition.
I.3.9 Evaluate the operation and configuration of the existing filter -to -waste (FTW)
system, and develop improvements.
1.3.10 Based on the results of the foregoing activities, propose recommendations to
improve filtration performance. These recommendations could include, but are
not limited to: media adequacy, backwash and surface wash rates and duration,
filter aid addition, backwash polymer addition, media support system, underdrain
configuration, and the FTW operation.
Subtask 1.4 - Filter Waste Washwater Study
Options available to treat filter waste washwater will be evaluated during this task.
Budget level costs and design criteria will be developed for identified methods to handle
washwater, Specific subtasks are described below.
I.4.1 Meet with City personnel to discuss and develop an understanding of filter
backwashing procedures.
1.4.2 Determine the quality and quantity of the washwater and the desired quality of the
recycled washwater.
I.4.3 Identify the type and capacity of treatment alternatives. Options include, but are
not limited to: lagoons, conventional treatment, mechanical dewatering,
discharge to sanitary sewer, and ceramic membrane filtration.
1.4.4 Develop costs and design criteria for the identified options.
Subtask 1.5 - Ozone Evaluation
The objective of this subtask will be to evaluate ozone as an alternate disinfectant.
Forthcoming regulations could require the addition of alternate disinfectants to inactivate
chlorine resistant pathogens, such as Cryptosporidium, as well as achieve higher
disinfection levels for Giardia. Ozone addition to raw and filtered waters will be tested
with Carollo's bench scale flow through test unit. Specific activities to be conducted as
part of this subtask are described below.
I.5.1 Establish ozone demand/dose relationships and ozone decay curves for raw and
filtered waters. Demand curves will be prepared with four points of measured
residual. Decay curves will be established for selected measured residual. Two
different detention times, most likely 10 and 20 minutes, will be evaluated for
each location.
I.5.2 Develop design criteria and costs to use ozone for disinfection for each location.
Subtask 1.6 - Report Preparation
A draft report summarizing the results of Subtasks 1 through 5 will be prepared and
distributed to each of the team members. The results of the report will be reviewed with
City staff in a meeting to receive comments.
1.6.1 Prepare a Phase I report and submit 10 copies to City staff for review.
1.6.2 Conduct a workshop to discuss the results of the investigations and receive
comments regarding the report.
I.6.3 Prepare 10 copies of the final report for distribution to the City.
