Search

for rainfall related inflow during wet weather periods. Continuous metering will be
conducted for the designated time period as directed by the Client.

The flow monitoring will be accomplished by one of the following methods:

1. The use of continuous monitoring devices incorporating a velocity sensor combined with
a depth sensor, or

2, Palmer Bowlus flumes, in conjunction with continuous depth recording.

D. Flow monitoring data reduction and review will be performed on all data obtained each flow
monitoring location. The data obtained will be reduced, evaluated, and presented in report
form. One (1) copy of the completed report will be submitted to the Client. This will
include, for each location, tabular reports based on 15-minute time increments,

The tabular report will be provided and will include:

A summary of daily flow information for a selected time period. The summary presents, for
each day, the minimum flow rate, peak flow rate, total daily flow, total rain, peak hourly rain,
and peak 15-minute rainfall, if applicable. The summary also includes the total flow volume,
average daily flow, and total rainfall quantity, if applicable, for the selected time period,

Detailed flow reports of the flow rate data in 15-minute time increments will also be
prepared and submitted. The detailed report will include depth of flow, velocity of flow,
incremental flow rate, cumulative flow rate and recorded rainfall. The report will also
include the total daily flow volume and total daily rainfall quantity, if applicable.

In addition, flow hydro graphs will be prepared for each flow monitoring location, which
present a plot of the recorded flow rates for a selected time period. A bar graph of rainfall
recorded during the selected time period is also plotted on the hydrograph.

Further, periodically data will be posted to a secure password protected web site that will
allow project personnel access to flow, rainfall and groundwater recorded data. Users then
can prepare and review detailed flow reports, graphs and tables. Comparison between wet
and dry periods as well as net flows per sub system calculations may also be performed.
Online data export format capabilities included Excel, Access, and ASCII.

HIEQUALITY CONTROL PROCEDURES
.FIELD OPERATIONS-SITE SELECTION

Since the flow monitoring site can play a significant role in obtaining accurate flow monitoring
data, site selection in the field will be given a high priority. The proposed monitoring site will be
visited for the specific purpose of observing flow characteristics. Every effort will be made to
identify a monitoring site that will provide accurate data while attempting to comply with the
original location plan.

Observations such as surcharging or backing up of flows are less than ideal for monitoring and if
possible will be avoided. Manholes having more than one line entering and irregular
flow/velocity patterns will also be looked on as less than favorable.

FLOW METER SELECTION/ANSTALLATION

Once a site has been identified the appropriate meter with any specific sensors will be installed.
The installation will consist of installing tight fitting aluminum bands with both flow depth and
velocity sensors mounted in such a way as not to obstruct flow or snag paper or other disposed
items in the flow stream.

INITIAL & SUBSEQUENT FLOW VERIFICATION

During the installation process, the meter will be operated in such a way as to instantaneously
obtain and display both depth and velocity readings. Manual depth measurements will be
obtained and compared to meter readings, any diffierences will be corrected to within 0.10
inches, Using a hand held velocity meter, readings will be obtained and compared to the metered
velocity readings and adjustments to the installed equipment will be made until a reasonable
match is obtained. During each maintenance visit, the following will be performed and noted on
site log sheets:

Actual depth of flow

Metered depth of flow

Actual flow velocity

Metered flow velocity

Flow pattern will be graphed for the previous period

Scatter plots of both depth & velocity will be reviewed

Any adjustments ( if necessary) will be noted

Battery voltage logged and if necessary, batteries will be replaced

DATA QUALITY REVIEW

Staff operating at our headquarters will review the flow data as it is received for completeness
(missing data). A more detailed review will take place at a later date when the actual Geld logs
atrive, Flow data files will then be combined with rainfall data and graphs will be prepared to
begin a more detailed review of all depth, velocity and flow data. Abnormalities such as
unexplainable depth spikes or drop outs as well as inconsistent velocity trends will be noted.
Additional comparison graphs will be prepared that will use both actual depth and velocity data
as well as predicted data. Scatter plots will also be produced to better understand specific
characteristics of the site as well as help identify isolated incorrect measurements. Adjustments
or corrections, if any, will be performed and documented.

IV. CLIENT RESPONSIBILITIES
The Client shall provide the following at no additional cost to the Subconsultant:

A. Furnish copies of the necessary plot maps of all sewers to be studied. The sewer lines and

Pump Station Upgrades Project ~ Phase II

To approve the contract with DeFelice Corporation of Dracut, Massachusetts in an
amount not to exceed $5,335,200, for construction of the Pump Station Upgrades Phase II
Project. Funding will be through: Department: 169- Wastewater; Fund: SRF Loan;
Activity: Pump Station Upgrades Phase IZ.

Attachments: DeFelice Bid

Discussion:

The City of Nashua owns 13 pump station stations and one CSO pump station in need of
upgrades. Phase I of the this project was completed in May 2021 which included 6 of the
most critical pump stations in need of renovation. Phase II will be to upgrade the
remaining 8 pump stations. Upgrades include completely new pump station buildings at 2
locations, new packaged pump stations at 3 locations, and various upgrades at the
remaining 3 locations. The project includes new fiber cable communication from the
pump station back to the wastewater plant.

The following three bid alternates are not included in the contract: Alternate D for tying
fiber optics cable into traffic control cabinets, Alternate E for additional fiber instailation
on Amherst Street, and Alternate F for installation of fire alarm wire. All 3 bid alternates
come to $127,325, and are for work outside the scope of the pump station project.
Another funding source is needed before it can awarded.

Woodard and Curran is the design engineer on this project. The Request for Proposal
went out on May 27, 2021. The bid opening was held on June 28th and the following bids
were received:

DeFelice Corporation $5,335,200
Albanese D&S, Inc. $6,728,200

DeFelice’s base bid of $5,335,200 is nearly equal to that of the Engineer’s estimate of
$5,324,000, hence, costs are considered reasonable. They have done satisfactory work on
Phase I of the pump station project as well as numerous sewer construction projects in the
past for the City of Nashua. They are well qualified for this work. References checked
were satisfactory on comparable projects.
