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.
