SCOPE OF WORK
Project No.E16264
Water and Wastewater Treatment On-Call Support
Task Authorization No. 18-ONSWTP Sodium Permanganate Bulk Storage and Chemical
Feed Improvements
PURPOSE
The City of Corpus Christi operates one(1) water treatment plant, O.N. Stevens Water Treatment Plant
(ONSWTP), which has a rated capacity of 161.5 million gallons per day (MGD). Along with the
conventional water treatment processes that are employed to provide treated water (i.e., coagulation,
flocculation, sedimentation, filtration, and disinfection), ONSWTP utilizes sodium permanganate
(NaMn04)as a pretreatment step in its water treatment process to control the growth of algae in the influent
raw water and provide pre-oxidation benefits.The current injection location and the lack of formal mixing
do not allow for efficient pretreatment of the influent water. The NaMnO4 chemical feed is manually
controlled by operators which does not allow for effective dosing,particularly as the water production at
the ONSWTP changes. Along with these concerns, there are currently no bulk storage facilities for
NaMnO4; therefore, ONSWTP staff must haul quantities of NaMnO4 to the injection location frequently,
which poses potential safety hazards.
The purpose of this task authorization is to provide assistance to the City staff by furnishing a Design Basis
Report related to the design and implementation of a NaMnO4 feed system and its associated chemical
storage facility. This report will provide a cost analysis, required exhibits and guidelines for the
development of contract documents,specifications and construction plans pertaining to the implementation
of the NaMnO4 system and its associated chemical storage facility.
SCOPE OF WORK
ADDITIONAL SERVICES:
ITEM 9—General Engineering
The Engineer will perform the following:
1. Conduct up to two (2) site visits to assess the existing NaMnO4 system, including the
current transportation and handling practices, existing storage facilities, chemical
injection location,and mixing methods.
2. Evaluate the existing NaMnO4 dosing and overall chemical usage for the influent raw
water,along with the mixing strategy for chemical dispersion.
3. Perform laboratory tests to determine the effect of different NaMnO4 doses on chlorine
demand and determine the required current dose of NaMnO4 for the plant.
4. Determine the required dose of NaMnO4 for future plant capacity of 200 MGD.
5. Develop design elements and determine the full scope of project based on condition and
capacity assessments.These design elements include:

• Chemical tank and containment area
• Chemical feed system
• Storage facility
• Identifying associated plumbing,electrical and instrumentation improvements.
6. Prepare a detailed Design Basis Report that will include the following:
• Challenges associated with the current system
• Recommended measures for improvement
• Detailed cost analysis
• Exhibits
• Guidelines for the development of contract documents specifications and construction
plans necessary for the implementation of recommended measures
DELIVERABLES
The Engineer will prepare a DRAFT Design Basis Report to the City for review and comment.Upon receipt
of comments,the Engineer will incorporate the necessary changes and submit one (1)hard copy and one
(1)electronic copy of the FINAL Design Basis Report.
SCHEDULE
The Engineer's services shall be performed in a timely manner consistent with sound professional practices.
The Engineer will complete the work according to the following schedule:
Activity Completion Date
Contract Execution-Notice to Proceed(NTP) TBD
Item 9—General Engineering
• DRAFT Submittal 6 weeks after NTP
• FINAL Submittal 12 weeks after NTP
The time limits set forth in the schedule shall include allowances for reasonable and expected review time
by the City and approval by authorities having jurisdiction over this project,and shall not be allowed as
cause for delay or adjustments to the schedule. Delays caused by review times by the City exceeding those
anticipated by the Engineer's schedule are cause for adjustments in the schedule. Any adjustments made
to the agreed upon schedule shall be made in writing and accepted by both parties.
The Engineer shall begin work immediately upon receipt of the executed Task Authorization and/or Notice
to Proceed(written or emailed).
FEE
The services will be provided on a Time and Materials (T&M) basis as the project is moved towards
completion.The anticipated amount for this task authorization is$51,888.60,as shown in ATTACHMENT
A. If the level of effort exceeds this estimate,a separate task authorization will be requested.
