SCOPE OF WORK
CITY OF CORPUS CHRISTI
Greenwood Wastewater Treatment Plant Dissolved Air Flotation Unit
Rehabilitation & Odor Control
CITY PROJECT NO. 18069A
PROJECT BACKGROUND
The City owns and operates the Greenwood Wastewater Treatment Plant (GWWTP), and is
interested in proceeding with improvements to the facility. A condition assessment completed in
April 2014 (E13118), identified several unit processes at the plant as needing rehabilitation or
improvements. In addition, the City is interested in mitigating odors present at the GWWTP that
are impacting the surrounding community. The City is looking to complete an alternatives
assessment to:
• Identify plant deficiencies,
• Recommend plant improvements and associated cost estimates, and
• Develop a conceptual design for the selected alternative to address both near and long-
term needs at the facility.
Although, previous studies have been performed at the GWWTP including: E13118—Greenwood
WWTP Asset Management Report (2014): E10047 — Greenwood WWTP Emissions and Odor
Control Improvements (2014); and the Wastewater Management Plan (2016, no comprehensive
process evaluation of the plant has been performed to date. The City is interested in performing
a comprehensive evaluation of the GWWTP to understand the limitations of the existing facility
and develop alternatives that vision the site for current and future needs
PURPOSE
The City selected Hazen and Sawyer (ENGINEER) to provide engineering services to
(1) Evaluate the existing unit processes at the GWWTP
(2) Assess up to three process train alternatives for upgrading the GWWTP, and
(3) Develop a conceptual design report for the selected alternative.
The intent of the alternatives assessment is to identify a plan for improvement that meets all
key goals and drivers for GWWTP while considering potential cost savings gained through
reconfiguring current operations. The objectives of project are as follows:
City Proj. No. 18069A Exhibit"A"
Page 1 of 21
1) A detailed process evaluation will include a hydraulic capacity evaluation
(development of the plant hydraulic profile), a treatment (liquids and solids) capacity
evaluation, and development and calibration of a biological process model for the
plant. The calibrated process model will provide a defensible basis for determining
viable process configurations and vetting performance of future regulations (e.g.
biological nutrient removal).
2) An alternatives assessment utilizing the calibrated biological process model will
evaluate up to three(3)alternatives for upgrading the unit processes at the Greenwood
WWTP. The alternatives assessment will detail the process and infrastructure
requirements needed to meet treatment goals to provide planning level costs and aid
in the selection of future GTP improvements
3) A conceptual basis of design and opinion of probable cost for the selected alternative
will provide a scope of work for detailed design improvements needed at the GW WTP.

addressed to reliably meet the plant's discharge permit limits.
• Evaluating the potential to modify the existing facilities to address any
identified deficiencies. Of particular importance is the aeration basin blowers
capability to turndown to meet air requirements during minimum flow
conditions.
The ENGINEER will utilize a process model to simulate plant performance under varying

sampling event) — the City will assist in setting up automated samplers (if they
currently are not used) for the WWTP influent, primary effluent and final effluent.
The City will collect the samples daily and the analysis will be filtered and analyzed
by City staff or their contracted laboratory
• Profile grab sampling (five separate profiles over three days)—the ENGINEER will
collect grab samples at various unit process and perform analysis in the field with
the exception of TSS, VSS, BODS and TKN which the City staff and/or contract
laboratory will analyze.

be analyzed to estimate sludge quantities and compared to actual sludge production
numbers. Sludge wasting,thickening, digestion, and dewatering facilities will be evaluated
to include:

addressed to reliably treat sludge produced based upon an annual average
plant flow of 8 mgd.
• Evaluating the potential to modify the existing facilities to address any
identified deficiencies.
