EXHIBIT A

20-YEAR FACILITY PLANNING STUDY (Phase 1)
CITY OF NASHUA, NEW HAMPSHIRE
WASTEWATER TREATMENT FACILITY
I. Scope of Work

This scope of work has been prepared for assisting the City in continuing its efforts towards
addressing current and future capital planning needs. The Wastewater Facility Planning Study will

include:

e Acomprehensive review of the current and projected future flows and loads,
e An assessment of the plant hydraulic and treatment capacity,

e An assessment of the process and ancillary equipment,

e The identification of potential discharge issues, and

e Identification of future capital improvement needs.

These evaluations will be conducted for the main wastewater treatment facility (WWTF), the wet
weather flows treatment facility (WWFTF), and the solids handling facilities. The tasks detailed
below summarize the proposed investigations in greater detail. We anticipate working with the
City in a step-wise manner with monthly progress meetings, brainstorming on each of the major
task elements, interim technical memorandum that summarize the findings of each task as it is
addressed, and then summarizing all of the findings and recommendations in the Report. The
report will synthesize the individual findings and document the overall implementation plan based

on a detailed review, discussion and approval by the City.

A. Preliminary Planning
1. Meet with City staff to review and confirm overall scope and approach of project.
Conduct brainstorming on each element of the scope of work to identify key
issues to be evaluated or problem issues to be addressed.
2. Review available plant data, including:
a. WWITF Monthly Operating Reports, quarterly toxicity reports, and other
operational data, including all available information on sludge quantities,

for the most recent 5-year period from 2014 through 2019. This will

12/10/19 1 Wright-Pierce

12/10/19

include reports for the WWFTF. It is assumed the other CSO facilities
are not part of this facility planning effort.

The current and draft NPDES permits, the status of discharge
requirements at the facility, and the pending application for a new permit.
The latest budget and Capital Improvements Plan (CIP). It is assumed the
City will provide:

e A summary of budgetary expenses over past 5 years by category,
including labor, electrical and fuel use, chemicals, sludge transport
and disposal, replacement parts and equipment, and other
appropriate categories.

e A summary of accounting for the WWTF within the City budget in
terms of funding for normal operations and capital improvements
and provide a summary of outstanding loans.

e The latest version of the Wastewater Equipment Replacement Fund
spreadsheet.

e <A current staffing plan both in terms of overall staffing levels and
structure and specific deployment during each work week.

e A summary of staffing changes over last 10 years.

3. Review past studies and reports including:

a.
b.

og f& 2

rh

Latest City master planning documents and GIS mapping files,

Latest update of the long-term control plan (LTCP) for CSO abatement,
Pump station upgrade plans,

Capacity Analysis Update (2017)

Inflow and infiltration (I/]) related efforts,

Facility O&M Manual with latest updates particularly for the aeration
upgrade project,

Basis of Design reports for all recent upgrade projects,

Energy audit reports,

Any other relevant reports and studies including the SCADA system
evaluation, and the condition assessment for the interior of the egg-shaped

digester.

2 Wright-Pierce

B. Project Administration and Meetings
1. Each month we will submit a report that details the work performed by the team
on each major task with the monthly project invoice.
2. The following meetings will occur throughout the duration of the project:
a. Eight (8) progress and brainstorming meetings with the project team and
City staff.

b. One project presentation meeting to present final report to City staff.

C. Define Current and Projected Future Influent Wastewater Flows and Loads

1. Analyze influent wastewater flows and loads for the five (5) year period from 2014
through 2019.

a. Trend average, minimum, maximum monthly, peak daily and peak hourly
flows for main WWTF including overall flows, secondary flow and
secondary bypass flow and WWFTF.

b. Trend average, minimum, maximum monthly, and peak daily loading data
for BOD and TSS to the main WWTF and the WWFTF.

c. Document septage flows and loadings and other commercial flows.

d. Summarize all available data for nitrogen, phosphorus or other parameters
in the influent.

2. City to provide future population and development growth projections within the
City’s currently sewered areas, including Tyngsboro, Hudson and any other
municipalities who may discharge to the Nashua system in the future.

3. Based on non-sewered population projections, estimate current and future septage
generation. Consider impacts of sewer extensions into areas currently served by
septic systems.

4, Utilize the results from the current Long Term Control Plan study to estimate
current and future infiltration/inflow flow rates.

5. Project future wastewater flows and loads for a 20-year planning period based on

projected growth and the anticipated impact of any CSO and J/I projects.

12/10/19 3 Wright-Pierce

6.

Prepare technical memorandum summarizing projected growth in residential,
commercial, industrial, and institutional flows. Meet with City staff to review and

finalize memorandum.

D. Analyze WWTF Effluent Quality and Sludge Quantities

12/10/19

1,

Analyze primary treatment removal rates for BOD and TSS and typical effluent
quality both in terms of concentration and mass loading. Summarize available data
on primary sludge quantities and compare to predicted values based on removal
rates.

Analyze available data on primary effluent nitrogen and phosphorus levels. If
necessary, develop a plan for supplemental nitrogen and phosphorus monitoring to
be conducted by the City (WP has budgeted an allowance of $7,500 for outside lab
effort). Develop a preliminary estimate of nitrogen and phosphorus loadings based.
on. best available information.

Analyze the performance of the secondary system in terms of flows treated, BOD
and TSS removal rates and typical effluent quality in terms of concentration and
loading.

For conditions when the secondary bypass is activated, analyze BOD and TSS
concentration and loading in primary effluent, secondary effluent, and combined
effluent.

Assess discharge permit compliance for the main WWTF both on days with no
secondary bypass and with secondary bypass including BOD and TSS
concentration and loading and effluent disinfection parameters.

Develop a summary of secondary sludge quantities.

Analyze sludge thickening operations for primary and secondary sludges including
capture rates and typical thickened sludge concentrations, flow and _ solids
quantities.

Analyze anaerobic digester performance in terms of solids loading rates, solids

destruction, and gas production.

4 Wright-Pierce

9. Analyze dewatering performance including solids capture, polymer consumption,
and cake solids. Summarize annual average, peak monthly, and peak daily sludge
quantities.

10. For WWFTF flows, summarize available data on BOD and TSS removal rates and

effluent quality in terms of concentration and loading.

E. Conduct Plant Infrastructure Assessment
1. Develop a comprehensive plant infrastructure asset inventory:

a. Assess options for asset inventory database including Excel spreadsheets;
Revit model with Access database; existing CMMS systems in use by
City; proprietary asset management systems; or a hybrid approach.

b. Based on the results of the above sub-tasks, develop a comprehensive
plant infrastructure asset inventory. For budgeting purposes, the use of
Wright-Pierce’s Excel-based Asset Management System has been
assumed. The existing WERF list would be incorporated into the overall
asset inventory. It is assumed the asset inventory will include a
comprehensive inventory of equipment systems, buildings and structures;
electrical control systems; and piping systems as separate worksheets in an
Excel workbook.

c. The initial asset inventory shall be populated with information on the age
of the asset, materials of construction, and typical life to replacement.

2. Conduct condition assessments identifying specific upgrade needs. Condition
assessments will include:

a. Process equipment and piping

i. Process equipment and piping assessment by process engineer(s)
updating remaining life estimates from existing WERF list and
expanding to any smaller equipment system added to inventory.

b. HVAC and plumbing systems will be assessed by a mechanical engineer
specializing in these systems.

c. Buildings, structures and tanks will be evaluated by a combination of

architect and structural engineer.
