Re: Evaluation and Preliminary Design of Class A Biosolids Management Upgrade in the amount not to exceed
$199,886.60 funded from 53107 Architect & Engineering Services/Wastewater Fund (Wastewater Department)

MOTION BY ALDERMAN COMEAU TO ACCEPT, PLACE ON FILE AND APPROVE THE CONTRACT WITH WRIGHT

IN AN AMOUNT NOT TO EXCEED $199,886.60. FUNDING WILL BE THROUGH DEPARTMENT: 169

Mayor Donchess

Mr. Boucher.

David Boucher, Superintendent of Wastewater

Thank you Mr. Mayor. The wastewater facility currently produces a Class B biosolid. We pay a management company to
dispose of it. They spread it on farmlands throughout New Hampshire and Massachusetts. With evolving regulations, we
found that it was getting harder and harder for these management companies to find places to dispose of it. Last time we
had a contract out, only one management company had submitted a bid and we are starting to see it getting harder and
harder to dispose of it anywhere.

So we want to look into producing a Class A biosolid. This is typically a further drying to reduce the weight of our
biosolids plus it also relaxes - well it opens up for more disposal options. More places are accepting of taking it. It’s
possible we could use it for some cap material at the landfill, but also trucking fees are increasing now also. So this would
also help reduce the cost of trucking as well.

We're also starting to see PFAS as the big topic. So the farms are getting nervous about that not wanting certain
products spread on their property. If we had to in the future go to disposing in the landfill, this would also decrease the
cost of trucking and tipping fees. So right now the company we want to use to do this work they have been in the facility.
They know our facility. They did a preliminary study already - a 20-year study on this. So they’ve already got a start.
Using them would help us get through looking at what type of Class A drying units. Every company does it by a different
method. There are some that are more efficient than others, but this would take us right up to what equipment we would
need. Also it’s possible that we’d have to expand one of our buildings to put this unit in. So it’s a big undertaking. I’d be
happy to answer any questions

Re: Digester Coating in the amount not to exceed $339,500 funded from 54210 Construction Services/Wastewater

MOTION BY ALDERMAN COMEAU TO ACCEPT, PLACE ON FILE AND APPROVE THE AWARD OF THE PRIMARY
AND SECONDARY DIGESTER COATING PROJECT TO JOHN W. EGAN COMPANY, INC., FROM WEST NEWTON,
MA, IN AN AMOUNT OF $339,500. FUNDING WILL BE THROUGH DEPARTMENT: 169 WASTEWATER; FUND:
WASTEWATER; ACTIVITY: DIGESTER/GAS TANK COATING

Mayor Donchess

Mr. Boucher.

David Boucher, Superintendent of Wastewater

Thank you Mayor. Wastewater facility two large tanks - one is a 500,000 gallon tank and one is a 1.3 million gallon tank.
They are due for a coating. They’re both steel tanks. The 1.3 million gallon tank actually has a foam insulation layer and
a rubberized layer so this project covers some repairs. There’s tears in the rubberized layer so they'd repair that,
sandblasting, and recoating both these tanks. Egan has done work for us in the past to factory conditions so I’d like to go
with them to do the work.
