January 31, 2008 Joint Meeting Minutes: Theodore G. made a motion to accept the minutes as printed, seconded by Brian P., New London voted in favor of the motion, Sunapee voted in favor of the motion, so declared by the Vice-Chairman.
Wastewater Treatment Highlights: Dave B. reported that there had been a meeting with a representative from EOS and he feels that there was much information gained from this. Dave B. reported that meter calibrations are scheduled for tomorrow and that from now on when these are done the A/D Instruments representative will call in the correct reading to EOS and they will then check the EOS system with the information from the calibrator. Dave B. reported that there had been some extremely high flows during the month of April but that he had no spills or overflows to report.
Dave B. reported that there is still a lot of sludge in the ditches and that he is going to put more sludge in a geo-bag tomorrow to make more room. There was some discussion regarding what size bags were being used and the reason for using the larger bags, as well as problems with getting tractor-trailer units over the temporary bridge. Charles S. questioned if there had been any discussion regarding what type of coagulant to use. Dave B. reported that Bob Urban had done some jar testing to determine which coagulant to use but that he does not have a definitive answer from him yet so is still using the coagulant that had been used originally.
Centrifuge: Theodore G. questioned if everyone had received the e-mail regarding centrifuges. Theodore G. stated that he and Paul M. feel that the geo-bags are not the best long-term solution to sludge handling and feel that centrifuges should be investigated further. There was some discussion regarding the listed price and what items that includes. There was some discussion regarding electrical upgrade that may be needed at the Wastewater Treatment Plant. Larry B. questioned how much volume in sludge would be produced from using a centrifuge. Paul M. stated that it would be difficult to establish the quantity but that the centrifuge would reduce the water content of the sludge by approximately 80%. There was some discussion regarding past investigations into de-watering
solutions. Charles S. gave a synopsis of the costs versus the benefits of each option. There was some discussion regarding the geo-bags and how labor intensive they are as well as the fact that they did not work during the cold winter months. Aaron S. feels that the use of the geo-bags never really got past the pilot study stage and that there were not enough trials done. Dave B. feels that he perhaps held the sludge too long in the tank which caused it to be thicker and more of a problem for the pumps. Charles S. questioned if the Siemans people could do a centrifuge demonstration at the plant for all the interested parties to see. Paul M. will find out if this or a trip to some other plant that uses one would be an option. George Neil gave some input as what else needs to be done to create a class A sludge. There was some discussion regarding the entire cost of setting up and running a centrifuge. Larry B. would suggest a presentation at the next meeting. There was some
discussion with George Neil regarding sludge handling and the different options.
Charles S. made a motion to appoint a committee of 4 representatives, 2 from Sunapee and 2 from New London to meet with Dave Bailey and plan a program to use whatever means necessary to take advantage of de-watering sludge and effect cost savings. Then to present a report on their findings to the Commissioners at the June 2008 meeting, seconded by Aaron S., voted unanimously in favor, so declared by the Chairperson.
EOS System: Richard L. stated that the EOS representative had told those present that the ProControl sheets should not be what is used for billing purposes. There was much discussion regarding billing and meter readings. Aaron S. stated that changing how the billing is done would require rewriting the intertown agreement. Richard L. would propose just setting a certain percentage for billing purposes to be reviewed every few years. Larry B. would propose that Holly L. and Jessie L. look into the percentages and come back with ideas for the next meeting.
7:05 p.m. the joint quarterly meeting was adjourned.
