- The Allenstown Sewer Dept. finally received a long-awaited state grant for $45,000. This covered part of the cost for sewer projects completed in the past. These funds will go back to the reserve fund that was used to pay for those projects.
January - May 2013
- Adopted a Septage Hauler Accounting Policy. This policy has increased our cash flow by changing the payment due date from the 25th to the 15th. Previously, there was only a verbal policy in place and the rules could not really be enforced. This was put in writing with credit limits for companies with late payments.
- Started requiring bonds for vendors that might have been turned off in the past, so that, if they did fail to pay a bill, we could go after their insurance company to pay us.
- Commissioners approved accepting credit cards as a form of payment from the Septage Haulers.
- Changed merchants for processing of credit card payments, saving approx. $1500 a year.
- Increased the hauler's permit fee from $50.00 to $100.00 per truckload. Despite the increase, all current vendors have renewed their permits.
- Department Staff installed baffles into clarifiers instead of by hiring a contractor, saving approx. $20,000.
- Removed Al's Avenue sewer line replacement from 2013 budget, saving approx $70,000.
- Changed the flat sewer user rate from $171.00 per quarter to $153.90. This was due to a decrease in the average daily flow from 250 gallons to 225 gallons per day.
- Eliminated the $20.00 disposal fee for residents of Allenstown and Pembroke for RV septic disposal. Non-residents still pay $20.00.
October 2013
State-of-the-art septage receiving station opened
Plant can now handle four trucks at a time.
2012
Sewer rate: $7.60/1,000 gal.
April 2012
- Saved the Sewer Department $17,500 on a new drum that reduced the use of magnetite daily. The reduced price was thanks to the staff at the plant who worked for weeks trying to locate one at a cheaper price.
May 2012
- Negotiated a new contract with Waste Management, Inc. for a savings of $6,500 per month.
July 2012
- Oak Street - Installed 350 feet of sewer main and a new manhole.
- Als Avenue - Removed a deteriorated manhole and replaced 90 feet of sewer main.
- Cross Street - Removed a cleanout that had been improperly installed many, many years ago, replacing it with a new manhole structure. The manhole is larger than a cleanout and used to join lines and continue a flow.
- Ferry Street - Repaired and paved the lower portion of Ferry Street after adding sewer line.
- Campbell Street - Replaced 375 feet of sewer main.
- Infiltration - Made improvements in the collection system that decreased ground water infiltration.
August 2012
- Switched to another energy supplier thus saving $2,000 per month. The new supplier, Glacial Energy, offered a very competitive rate and we locked that in for a two-year period.
- Installed natural gas lines to the treatment plant to convert from oil to natural gas, resulting in a fuel savings.
September 2012
- Retained the same firm as the town to audit all sewer plant books for transparency. We had them review the last three years of information, reviewed the current year (2012) for errors, and trained our staff in correct accounting procedures.
November 2012
- Established an increase in the septage haulers rate to take effective on January 1, 2013.
- Announced that there would be no increase in the sewer rate for residents.
December 2012
