BASIC SERVICES
1. COLLECTION SYSTEM REHABILITATION CONTRACT
A. Review historical maintenance and Sanitary Sewer Overflow (SSO) records.
The review of historical records for the past three (3) years will determine areas
within the City of Corpus Christi sanitary sewer system that are potentially
influencing system performance resulting in Sanitary Sewer Overflows or that
require repetitive maintenance activities. Rehabilitation design efforts by the AlE to
include all methods available in the municipal sanitary sewer construction area.
This task will'
· Review existing records to assist with identifying areas that can be included in
the Collection System Rehabilitation Contract.
· Review the 'As-Built Drawings of the sanitary sewers in the areas where the
SSO occurs.
· Review the City provided video tapes, records and any other data which may be
available to prepare the scope of rehabilitation work.
· For Collection System Rehabilitation, Earth Tech will collect all information
necessary, including depths of manholes and if necessary get the topographic
survey performed for the area where the line rehabilitation work is to be done.
· Review the City's wastewater related Standard Specifications and revise them
appropriately to reflect the most current methodology and standards used and
approved by the USEPA, WEF, AMSA and any other related agencies.
· Coordinate design details with Engineering Services and Wastewater staff.
· Prepare and submit design reports to Texas Commission for Environmental
Quality (TCEQ) and Texas Water Development Board (TWDB).
2. ALLISON WASTEWATER TREATMENT PLANT SERVICE AREA INFLOW-
INFILTRATION (I-I) SANITARY SEWER EVALUATION SURVEY (SSES) FOR FIVE
(5) SUB-BASINS.
Deterioration of the City's Wastewater collection system allows infiltration and inflow of
water and foreign material into the system. This results in reduced line capacity and
manhole overflows potentially leading to non-compliance with environmental
regulations. Preliminary improvements are to have smoke testing, line cleaning and
televising for condition reports to determine the highest priority sections of the collection
system. Reports that enable the City to meet Capacity, Management, Operations, and
Maintenance (CMOM) requirements must be generated. Proposed improvements
involve installing flow monitors, rehabilitating collection lines and lining or reconstructing
manholes with fiberglass. This is an on-going program that continually provides
maintenance and improvements. as funding allows, for optimal performance and
integrity of the City's wastewater system. This will lead to required improvements to
limit infiltration and inflow

E. Temporary Flow Monitorinq
· In order to perform a detailed analysis of infiltration/inflow, capacity requirements
and establish the baseline dry and wet weather flows within the service area, it
will be necessary to obtain flow monitoring information during both dry and wet
weather. Under ideal conditions, multiple rain events of varying intensities will
be monitored in order to accurately assess the inflow response for each event.
It is anticipated that a maximum sixty (60) day flow monitoring will be
performed during optimum wet weather periods. The monitoring period may
be extended beyond 60 days if inadequate rainfall occurs, but only upon the
Citys written approval to extend the metering period for the unit price specified
in the contract. Table 1 presents the normal monthly rainfall for Corpus Christi.
Based on the project timing, it is anticipated that the April - June, 2006 period
would be used for scheduling the temporary flow monitoring. Information
obtained dunng the rnonitoring period will be used to determine the following:
1 Average (jaily flow - dry weather
2 Peak flow - dry weather
3 Average daily flow - wet weather
4. Peak flow - wet weather
5. Peak inflow rates
6. Total 1/1 volume

. Meter Installation, Calibration and Data Collection
Each meter will be field calibrated prior to installation. Calibration of each meter
will consist of a verification of the flow depth and velocity. The flow sensors will
be secured to a mounting band that fits securely in the pipeline. The data logger
for each site will then be installed and secured in the top of each manhole and
the meter will be activated at user defined sampling intervals, typically 15
minutes. Routine maintenance and service will be performed weekly to confirm
standard operation. It is estimated that five (5) continuous flow meters and three
(3) rainfall gauges will be installed for a 60 day period to obtain flow and rainfall
data. Note that the May-June period and August - September are the optimum
times to record wet weather flows

F. Smoke Testinq of the Study Area
· Smoke testing will provide detailed information on wet weather inflow sources to
be performed on 202,198 linear feet of pipeline, which will be in the defined
study area. in order to identify defects in the lines, a non-toxic smoke will be
forced into the sewer by high capacity blowers. Data documentation will be
sufficient to establish the location of each defect and determine the best repair
method and priority. Color digital photographs will be taken to document each
defect during the smoke test. Field forms presented in Exhibit A-4 or approved
equal, will be used to record smoke testing data.
· Forty-eight (48) hours prior to testing, door hangers approved by the City of
Corpus Christi will be used to notify residents. A local telephone number will be
provided for those individuals with questions or for anyone requiring special
assistance. Each day the fire department will be notified of the crew location
since smoke may enter homes through defective plumbing.
· This scope of services will identify inflow defects primarily on the municipal
mainline sewer, but also on private service lateral. Defects on private property
will be photographed and documented. GPS coordinates for each defect will be
recorded where possible (+or - 3 meters). This procedure will minimize the
impact to residents yet provide detailed information for the establishment of
CCTV needs. prioritized repair plan and methods.

. Dyed water testing will be used to assist in the location and quantifying of
specific defects during the internal television inspection at an estimated twenty-
five (25) locations. Non toxic dye may be introduced as a powder or liquid to
assist in the field effort. Casting/Cone connections may be dye tested to
determine the potential severity and exact location of the source of wet weather
inflow. Cross-connections, roof drains and area drains that are suspected of
being connected to the sanitary sewer will be positively identified using the dye
tracer procedure. Field documentation and photographs will be used to record
all findings.

9 Expose/Uncover Buried Manholes & Cold Patch or use CCTV to locate
manholes if approved by City. (Allowance)
. The effort for this task IS covered under an allowance and the unit cost fees
Identified In Exhibit A-3.
10. Traffic Control Plans - Traffic Control Plans will be required during all CCTV, line
cleaning, smoke testing, and dyed waterflooding being performed within or adjacent
to the City's roadways.
A A/E will meet with Engineering Services and the Traffic Department to discuss
the expected traffic situations and will determine the most feasible traffic control
for each situation.
B AlE will produce up to ten (10) traffic plan sheets and will have them pre-
approved by Engineering Services prior to beginning SSES.
11. Manhole Inspections
A Field inspection crews will perform an inspection of 573 manholes. The data
gathered dunng this phase of the project will be used to prioritize manholes for
rehabilitation and establish the base data necessary to accurately determine
mainline sewer rehabilitation alternatives and costs (such as confirming line
sizes, line depths, cover. etc.).
B Other important deliverables resulting from this work task is the updating of the
GIS collection system map and determination of debris levels in pipes. This
information is critical in preparing subsequent rehabilitation plans.
C Inspection personnel will use digital cameras during the inspection of all
manholes on this project. All photographs will be in a digital format and included
in the field inspection computer database so that a permanent electronic record
can be maintained.
D Field forms presented in Exhibit A-4 or approved equal, will be used to record
field inspections. During inspection, each of the following types of information
will be obtained to pnoritize least cost repairs (Through additional services, A/E
shall attempt to open all manholes):
1. Basin Designation
2. rv1anhole 10
3. Inspection Status
4 Street Address and GPS coordinate (3 meter accuracy) of manhole
5. Surface cover, grade, type of cover (paved, yard, etc.)
6. Material of construction - brick, concrete, etc.
7. I nternal photo of manhole
8. Outgoing pipe depth from rim to invert
9. Debris depth
10. Defects- Active, Evidence or No Infiltration/Inflow

intrusion deterioration of mortar joints. loose or missing bricks,
signs of surcharge level, etc.
14 The bottom of the manhole will be checked for type and depth of
debris, flow conditions through the manhole and any signs of
settlement that may impede achieving design flows.
15 All sewer lines entering and leaving each manhole will be compared
to existing maps and corrections will be noted. All sewer line to
manhole connections will be inspected to determine if any manhole
settlement has separated or sheared pipelines.
16 Incoming and outgoing pipeline will be digitally photographed to
document and determine the general condition of the line.
17 Any silt deposition that reduces flow capacity will be noted and silt
depth recorded. Observed defects (root intrusion, cracked pipe,
obstructions, etc.) will be documented and photographed.
E Upon completion of the manhole inspection. a prioritized manhole rehabilitation
summary will be prepared

· Documentation for preparing manhole rehabilitation bids
· Prioritized cleaning recommendations to restore capacity
· Field Updated Map and GPS coordinates
· Prioritized Manhole Repair Recommendations and Cost Estimates
(Priority 1, 2, & 3 Rankings)
· Manhole Inspection Reports
12. Smoke Testing -
A Smoke testing will provide detailed information on wet weather inflow sources to
be performed on 202,198 linear feet of pipeline, which will be in the defined
study area. In order to identify defects in the lines, a non-toxic smoke will be
forced into the sewer by high capacity blowers. Data documentation will be
sufficient to establish the location of each defect and determine the best repair
method and priority. Color digital photographs will be taken to document each
defect dunng the smoke test. Field forms presented in Exhibit A-4 or approved
equal, will be used to record smoke testing data.
B. Forty-eight (48) hours prior to testing, door hangers approved by the City of
Corpus Christi will be used to notify residents. A local telephone number will be
provided for those individuals with questions or for anyone requiring special
assistance. Each day the fire department will be notified of the crew location
since smoke may enter homes through defective plumbing.
C This scope of services will identify inflow defects primarily on the municipal
mainline sewer, but also on private service lateral. Defects on private property
will be photographed and documented. GPS coordinates for each defect will be
recorded where possible (+or - 3 meters). This procedure will minimize the

13. Dyed Water Testing -
A Dye water testing will be used to assist in the location and quantifying of specific
defects during the internal television inspection at an estimated twenty-five (25)
locations. Non toxic dye may be introduced as a powder or liquid to assist in the
field effort. Casting/Cone connections may be dye tested to determine the
potential severity and exact location of the source of wet weather inflow. Cross-
connections, roof drains and area drains that are suspected of being connected
to the sanitary sewer will be positively identified using the dye tracer procedure.
Field documentation and photographs will be used to record all findings.
14. Temporary Flow Monitoring -
.A In order to perform a detailed analysis of infiltration/inflow, capacity requirements
and establish the baseline dry and wet weather flows within the service area, it
will be necessary to obtain flow monitoring information during both dry and wet
weather. Under ideal conditions, multiple rain events of varying intensities will
be monitored in order to accurately assess the inflow response for each event.
It is anticipated that a maximum sixty (60) day flow monitoring will be
performed during optimum wet weather periods. The monitoring period may
be extended beyond 60 days if inadequate rainfall occurs, but only upon the
City's written approval to extend the metering period for the unit price specified
in the contract. Table 1 presents the normal monthly rainfall for Corpus Christi.
Based on the project timing, it is anticipated that the April - June, 2006 period
would be used for scheduling the temporary flow monitoring. Information
obtained dunng the monitoring period will be used to determine the following:
1) Average daily flow - dry weather
2) Peak flow - dry weather
3) Average daily flow - wet weather
4) Peak flow - wet weather
5) Peak inflow rates
6) Total 1/1 volume
7) Capacity Analysis (dry and wet weather)

B Meter Installation, Calibration and Data Collection
Each meter will be field calibrated prior to installation. Calibration of each meter
will consist of a verification of the flow depth and velocity. The flow sensors will
be secured to a mounting band that fits securely in the pipeline. The data logger
for each site will then be Installed and secured in the top of each manhole and
the meter will be activated at user defined sampling intervals, typically 15
minutes. Routine maintenance and service will be performed weekly to confirm
standard operation. It is estimated that five (5) continuous flow meters and three
(3) rainfall gauges will be installed for a 60 day period to obtain flow and rainfall
data. Note that the May-June period and August - September are the optimum
times to record wet weather flows.

H.B. 914, passed during the 2005 legislative session, became effective on January 1,
2006. The bill enacts Local Government Code Chapter 176
It requires a vendor that wishes to conduct business or be considered for business with
a city to file a "conflict of interest questionnaire." The conflict of interest questionnaire
(FORM CIQ) was created by the Texas Ethics Commission (TEC) and is available,
along with a list of the local government officers of the City of Corpus Christi, online at
www.ethics.state.tx.us or the City website at www.cctexas.com or from the City
Secretary's office, City of Corpus Chnsti. Also, a vendor can obtain a copy of H.B. 914
from the City Secretary's Office Any questions regarding the conflict of interest
questionnaire should be addressed to the Texas Attorney General.
The bill defines who must file the conflict of interest questionnaire:
· Any person who contracts or seeks to contract for the sale or purchase of
property, goods, or services with a local government entity; and
· An agent of a person who contracts or seeks to contract for the sale or purchase
of property. goods, or services with a local government entity.
The bill appears to apply to all persons or businesses who conduct business with the
city, including those who submit bids on city contracts, make purchases of surplus city
property, or participate in any other purchase or sales transaction with the city.
A vendor shall file a completed conflict of interest questionnaire with the City Secretary
not later than the seventh business day after the date that the vendor:
· Begins contract discussions or negotiations with the City; or
· Submits to the City an application, response to a request for proposals or
bids, correspondence, or another writing related to a potential agreement
with the local City
A vendor shall file an updated completed questionnaire with the City Secretary's Office
not later than:
· September 1 of each year in which an activity is pending; and
· The seventh business day after the date of an event that would make a
statement in the questionnaire incomplete or inaccurate.
A vendor is not required to file an updated completed questionnaire in a year if he has
filed a questionnaire on or after June 1, but before September 1, of that year.
A vendor commits an offense if the vendor violates this section. An offense under this
subsection is a Class C misdemeanor
