of goods and services necessary for water quality improvements in
an amount not to exceed $2,720,000, and authorizing the City
Manager, or designee, to execute all documents necessary for these
emergency procurements pursuant to State law and Article X,
Section 2 of the Charter of the City of Corpus Christi
WHEREAS, events in May led to the issuance of a community "boil water" notice
mandated by the Texas Commission on Environmental Quality due to low disinfectant
residuals in the City's water distribution system;
WHEREAS, goods and services, necessary to ameliorate water quality problems
in the City's water distribution system and improve the overall functionality of the
system, must be procured as expeditiously as possible;
WHEREAS, State law provides that such procurements, as outlined above, are
subject to statutory procurement requirements, including competitive solicitations and
bids, unless an exception applies;
WHEREAS, there are two applicable statutory exceptions for these

Item Estimated Description/Justification
Cost
Four Chemscan The four(4)existing ammonia/monochoramine analyzers are obsolete
Analyzers for and unreliable. Accurate and reliable analyzers are essential to
treated water establishing stable water quality as they provide plant operators with
monitoring at the $150,000 the tools needed for better monitoring and control of chlorine and
O.N. Stevens ammonia. The proposed analyzers are required because they have an
Water Plant established track record of reliable service at many utilities and because
they provide additional capabilities of monitoring total chlorine levels.
Tank Mixer for Due to the location of the tank, and flow and pressure trends of the
Flour Bluff $40,000 water system, it is often difficult to maintain uniform and stable
Elevated Storage chlorine residuals in the tank. A mechanical mixer is required to help
Tank establish uniform water quality in the reservoir.
Sampling Currently,the water quality monitoring capabilities for the elevated and
Program for ground storage tanks is limited. This sampling program is required to
Elevated and $26,000 gain a better understanding of the water quality variations in the tanks
Ground Storage and to determine whether improved monitoring and/or mixing is
Tanks needed.
A new chlorine dioxide(CIO2) system at the ONSWTP will provide a
number of benefits such as reduced THM formation potential, improved
Chlorine Dioxide control of nitrification, and reduced oxidant demand, which would
Annual Chemical $750,000 result in reduced pre-chloramination dosing. The most common way of
Costs producing CIO2 is by facilitating a chemical reaction between chlorine
and sodium chlorite. This item addresses the anticipated annual costs
associated with purchasing the sodium chlorite.
A sodium hypochlorite storage and feed system will provide for
Chlorine Dioxide boosting chlorine to tie up residual ammonia (FAA)at the City of
Annual Chemical $250,000 Corpus Christi's Navigation Pump Station. High FAA is recognized as a
Costs common cause of nitrification in water systems. A chlorine booster
station will provide the operators with the ability to reduce FAA in the
distribution system.
Chlorine Dioxide A new chlorine dioxide system at the ONSWTP will provide a number of
System benefits such as reduced THM formation potential, improved control of
Improvements at $850,000 nitrification, and reduced oxidant demand, which would result in
O.N. Stevens reduced pre-chloramination dosing.
Water Plant
Tank Mixers for The largest storage volumes of water in the distribution system are
Navigation and currently stored at Navigation and Staples Pump Stations, and as a
Staples Ground $150,000 result,water age is impacted at these locations. A mechanical mixer
Storage Tanks will provide for each tank to help maintain uniform water quality in the
reservoirs.
Managing and monitoring nitrification is only an issue for water systems
using chloramines as the primary disinfectant. The City is currently
O.N. Stevens investigating the feasibility of permanently switching from chloramines
Water Plant Pilot to free chlorine as the primary disinfectant. Prior to implementation,
Model for $300,000 bench top testing and a pilot study must be performed to determine
Granular GAC performance, change out frequency of the media, and ultimately
Activated Carbon the costs and viability. This item will provide the City with a physical
model of the ONSWTP which can be used for piloting and testing the
GAC along with other operational and capital improvements.
Granular In addition to the Water Plant Pilot Model for Granular Activated Carbon
Carbon $200,000 as listed above item, this item includes the costs associated with
ActivatedranStudy operating and monitoring the GAC pilot for up to 6 months and a
Pilot providing a report on the findings and recommendations.
