I. PROJECT BACKGROUND
• BASE CONTRACT:O.N.Stevens Facilities Feed Improvements(Chlorine/Chloramine Assessment)
project(City Project No. 8605)
The O.N. Stevens Facilities Feed Improvements (Chlorine/Chloramine Assessment) project (City
Project No. 8605) was executed in June 2008. The purpose of this project was to provide preliminary
design services to help the O.N. Stevens Water Treatment Plant(ONSWTP)meet TCEQ requirements
for chemical dosing. This involved improving chemical bulk storage facilities, chemical feed and
handling at the plant for liquid ammonium sulfate (LAS), caustic soda, potassium permanganate and
cationic polymer.
• AMENDMENT 1: O.N. Stevens Water Treatment Plant Facilities Feed Optimization
Amendment l to O.N Sevens Facilities Feed Improvements (Chlorine/Chloramine Assessment)
project(City Project No. 8605)was executed in July 2010 to provide engineering services for the O.N.
Stevens Water Treatment Plant Facilities Feed Optimization project (City Project No. E17047). The
scope of this project involved providing design, bid and construction phase services for the following
improvements at the plant. This project was later combined with the Raw Water Influent
Improvements project(8643) and is currently in its design phase.
o Chemical Storage and Chemical Feed Systems
o Sedimentation Basin Hydraulic Improvements
o Programmable Logic Controller(PLC) Upgrades
• AMENDMENT 2: O.N. Stevens Water Treatment Plant Facilities Feed Optimization Improvements-
Fluoride
In September 2015, a zero-dollar amendment 2 was executed to the contract. The scope of this
amendment included providing engineering services for the O.N Stevens Water Treatment Plant
Facilities Feed Optimization Improvements-Fluoride project (E15233). The project involved
EXHIBIT A
Page 3 of 21
demolition of the existing fluoride facility at the ONSWTP and construction of a new fluoride system
including chemical storage, chemical feed, chemical injection, instrumentation, electrical and
structural improvements. The project was recently completed.
• PROPOSED AMENDMENT 3: Sodium Permanganate Bulk Storage and Chemical Feed
Improvements Project
The City of Corpus Christi (City) has requested that unallocated funds remaining in the the O.N.
Sevens Facilities Feed Improvements (Chlorine/Chloramine Assessment) project (City Project No.
8605) be used through a zero-dollar amendment 3. The scope of this amendment will be to provide
engineering services for the design and construction of a new sodium permanganate bulk storage and
chemical feed system at the ONSWTP.
II. GENERAL INFORMATION
The O.N. Stevens Water Treatment Plant (ONSWTP) has a rated capacity of 161.5 MGD and
provides treated drinking water to the City of Corpus Christi.At the ONSWTP,conventional treatment
processes like coagulation, flocculation, sedimentation, filtration and disinfection are used to
effectively treat the influent raw water.The plant receives raw water from Choke Canyon/Lake Corpus
Christi, Lake Texana and Colorado River and the water from the different sources is routed to the
plant's raw water junction box where it is blended together. Influent raw water is sent to the pre-
sedimentation basin to allow the larger particles in the water to settle. Due to the high organic matter
and nutrients in the raw water sources, water temperatures and detention times, a significant algae
problem is often noticed at the pre-sedimentation basin.Algae formation hinders the treatment process
downstream by clogging filters and also alters the taste and odor of the water.
In order to minimize algae formation and oxidize low-level impurities in water such as iron,
manganese and arsenic, water is dosed with sodium permanganate. While sodium permanganate is
effective in its role as an oxidant and algae reducer, at present,there is no permanent chemical storage
facility for the chemical on site and it is handled and fed manually by plant operators. This is a safety
hazard and also causes procurement,operational and dosing challenges for the plant staff. The current
EXHIBIT A

.
challenges, historical dosing, estimated future demand and proposed bulk storage and feed system
design basis have been discussed in detail under E16264-TA18-Sodium Permanganate Bulk Storage
and Chemical Feed Improvements Design Basis Report.
III. DESCRIPTION OF PROJECT SCOPE
The purpose of this project is to build on the work completed under E16264-TA18-Sodium
Permanganate Bulk Storage and Chemical Feed Improvements Design Basis Report and design a
new containment and chemical feed system for sodium permanganate at the ONSWTP. Under this AE
contract,the Engineer will provide design and construction phase services for the following upgrades
at the plant:
• Site preparation
• Sodium Permanganate Bulk Storage Containment Area
• Sodium Permanganate Chemical Feed System
• Sodium Permanganate Injection Locations
• Yard Piping
• Electrical and Instrumentation Improvements
IV. SCOPE LIMITING ASSUMPTIONS
The following scope limiting assumptions have been defined:
• The scope of work for this project will build on the work completed under the Sodium
Permanganate Bulk Storage and Chemical Feed Improvements Design Basis Report (City Project
No. E16264-TA18). Due to this the design phase of this project will not include a 30% or 60%
design submittal. The City staff will be able to provide input and review key design decisions
during monthly project meetings. The Engineer will prepare a 100% pre-final submittal for City
review and a final signed and sealed set of bid documents, incorporating all necessary comments
and suggestions.
EXHIBIT A
Page 5 of 21
• It is to be noted that several improvements are being made at the front-end of the ONSWTP. The
proposed sodium permanganate injection point under the current scope of work is intended to be
located at the raw water junction box which is being designed and constructed as a part of the O.N.
Stevens Water Treatment Plant Raw Water Influent and Chemical Feed project. This scope of
work assumes that while the injection point will be designed as a part of this project, the
construction will occur under the O.N Stevens Water Treatment Plant Raw Water Influent and
Chemical Feed project. Design and construction details will be closely coordinated between both
project teams.
