Digester Cleaning Project —-CO1

To approve change order 1 to the Digester Cleaning contract with Denali Water
Solutions in the amount of $48,400. Funding will be through: Department: 169
Wastewater; Fund: Wastewater; Account Category: 81 Building Improvements.

Change Order 1 Backup

The Primary and Secondary Digesters at the Nashua Wastewater Treatment
Facility are in need of cleaning. This is a large scale specialized project requiring
a contract with dewatering brought on site to perform this service over a 4-6 week
period. The project was bid in August and Denali Water Solutions was the low
bidder with a cost of $273,310.

In addition to dewatering the sludge, the Wastewater Facility and Denali have to
coordinate with Casella Organics on the transport and removal of the sludge.
Since the sludge removed from the process while the digester is being cleaned no
longer meets class B sludge, it cannot be land applied and has to be delivered to a
landfill owned by Casella. Casella and the landfill have required that odor control
measures be taken on the dewatered sludge. Casella will not transport or allow
sludge to be delivered to their landfill with strong odors.

A meeting was held recently with Casella and Denali during which Casella gave
specific recommendation on the odor control system to use. They recommended
the contractor use Remedia, a company with a propriety odor contro! chemical.
This company provides pumps, setup, chemicals and supervision as needed. The
contractor costs for odor control comes to $48,400.

RE: Nashua NH Digester Project.
Mr O’Hara
It was a pleasure discussing the upcoming Nashua NH digester project this am.

As requested [ have included our Post Dewatered Sludge target application assumptions based
upon the information provided within your email of 10 f1L/17,

As mentioned as courtesy to new clients we will agree to design, furnish, install, and maintain a
product application system for no charge to clients ordering a minimum of 2- 275 gallon
tote(s) of Remedia Industrial Odor Eliminator, (Plant to Supply Water and Electrical
Connections as necessary and all installed equipment remains property of Remedia at project
completion).

We continually provide product and application support for active clients in an effort to ensure
the cost effective use of our product as an efficient odor mitigation strategy.

As cai be seen on the above target application sheet we are suggesting initially calibrating the
system to inject approximately 198 gallons of product per load followed by a topical treatment
of 35 gallons for a total of 2.0% of the cake weight.

Based upon a 6 week project schedule this facility is budgeted at 1,375 gallons of usage or 5 -
275 gallon IBC totes.

.

Our Budgeted Cost for Mobilization, Installation and Product for the above project will be
$44,000.00 USD.

Lead time from product order to implementation is approximately 10 days.

Based upon the information provided we would propose a dual injection point within the lid of
your post centrifuge discharge screw conveyor.

¢

To effectively design and implementa topical application system we would require a plant
inspection to determine the most cost effective suitable location for deployment ofa tapica!
application system,

1) Domestic Water Supply - Min of 32 PS] and 14.6 GPM will be required by others.
2) 115V - 20 amp electrical service shall be suppited by others.

Per your request for an alternate odor mitigation solution for ambient post process air from
the centrifuge we would propose to inject a fragrant Pre centrifuge at the rate of 1 gallon of
concentrate to 500 gallons of process water.

Application here can be done by a simple metering pump discharging to the In-Flow line.

Our Budgeted Cost for Mobilization, Installation and Product for the above project will be
$25,200.00 USD.

Should you have any questions and or concerns please reach out to me directly at 302-690-
3911.

In closing | appreciate the opportunity of working with your group and look ferward to
providing a reliable cost effective Odor Mitigation strategy that achieves the objectives of the
City of Nashua as well as Denali Water Solutions.

headwalls to be constructed at the end of drainage pipes, 1 outlet control structure, and 1 dumpster
enclosure. Change order #1 also adds 5 working days t the contract time. Change order 1 has a net
effect of reducing contract cost by $12,878.52

Change order #2 added geotextile CL.3, pipe liner, and timber guardrail as new items. This change order
also increased quantities of clearing and grubbing, removal of existing pipe, excavation, Rock
excavation, embankment in place, structure excavation, crushed stone, pavement, stone fill class C,
geotextile, bituminous sidewalk, concrete sidewalk, traffic signage, sawed concrete pavement, sawed
bituminous pavement. Finally the change order decreased quantities of removal of catch basin/manhole,
