Augustus Seamans, Chairman, Gordon Starkey, Betsy Boege, Doug Gay PRESENT from Sunapee: Bob Henry, Chairman, Tracy Nangeroni, John Wheeler, David Montambeault, Helen Charpentier, Dave Bailey ALSO PRESENT: Jessie Levine, NL Administrator, Ed Rushbrook, Underwood Engineers, Ann Bedard The meeting was called to order at 4:30p.m. by Gus Seamans. BUSINESS: Minutes from the Joint meeting, March 31, 2005, were approved. FLOW METER SUMMARY REPORT: Ed Rushbrook gave a 20 minute power point presentation on the results and recommendations of the flow meter report. His firm has physically inspected the six meters involved between the two towns, tested signal strength, performed draw down test where possible, and provided an opinion on reliability of the meters. Ed explained the similarities and differences between the meters at all locations and how each meter worked. (Schematic hand outs.) New London Plant venturi meter Town Line Flume ultrasonic level sensor Georges Mills Pump Station Doppler meter (similar to sonar) and venturi meter (dry side pumps) Sunapee Library Doppler meter Sunapee Wastewater Treatment Facility Weir ultrasonic level sensor Ed explained that the PLC Analyzer (Programmable Logic Controller) is a mini computer that converts depth, pressure and velocity measurements in the different meters to flow data. That in turn is recorded in each location for that meter. Ed explained that calibration is only checking the signal between a meter and its PLC. Checking the signal (calibration to us) does not mean that a meter is accurately reading the flow and is not the same as a true calibration which can only be performed by measuring flow passed through meters by a drawdown test or similar process. At all the meters there are variables that can lead to inaccurate readings. Summary: NLP Venturi Meter Evaluation: reading @11% lower than draw down test. Recommendation: EOS unit from Sunapee Library location be relocated to calculate flow rate and replace the function of the Venturi unit. Town Line Flume (open channel meter) Ultrasonic Level Detector - Evaluation: determined fairly accurate from zero flow test. Recommendation: replace level sensor; monitor depth of flow in flume and compare to instantaneous flow readings to assess accuracy of the meter. GMPS - Doppler Meter Evaluation: draw down test showed meter under reading @35%. There is a question of whether the installation meets manufacturers specs. Recommendation: adjust meter as necessary after obtaining manufacturer opinion and recheck with draw down tests. GMPS - Venturi Meter Evaluation: Limited test performed. Recommendation: abandon centrifugal pumps and this meter. Sunapee Library Doppler Meter Evaluation: least reliable flow figures; not properly installed or located. Recommendation: abandon this meter and relocate the EOS system to the NLP for more accurate readings there. Sunapee WWTF Evaluation: not tested because meter weir plate does not meet standards and should be replaced. Recommendation: replace weir plate, seal bypass around weir plate, then measure head over weir. General Metering Discussion: Metering - Ed stated if all these meters were adjusted and tested after adjustment, he felt that the meters might only need to be checked yearly or semiannually not necessarily calibrated quarterly. The permit requirements define how often calibration is required. Dave M would like to see whole package developed. Other Discussions: Sunapee is not sure when their discharge permit will be renewed, so trying to wait to see what the whole package of requirements might not be timely. Sunapee is not sure about taking the bypass out, but just close it off. Assessments need to be made as to whether to go with a Flume, V-Notch or a straight edge weir plate. A flume would be most accurate. It was suggested for billing purposes along Jobs Creek Road (the force main that Sunapee contributes into via their neighborhood pump stations) a system be set up to use pump run times from the 3 pump stations to develop flow into the system instead of Sunapee Library meter. There are currently three pumps running in GMPS. Doug explained it was a Lead-Lag-Lag setup. The station was originally a two pump system. Ed is recommending abandoning the older centrifugal pumps and using the two newer more technologically advanced submersible pumps now in place. This recommendation is endorsed by the New London Commission. Gus closed this discussion by suggesting Sunapee think over what they might want to do about the SWWTF weir plate, calibration, and the Sunapee Library Meter. Both Commissions will talk again. 2. SUNAPEE MANHOLE Route 11, in Georges Mills: Dave Bailey brought some prints of what flows into this manhole from Sunapee. The question that has not been answered was If this manhole is made water tight, what does it do to the Sunapee System? Ed presented a schematic to show what the elevation issues were, but when asked for a solution, he stated that a detailed evaluation of the Sunapee manhole was not in the scope of the assignment contracted by New London. Dave Bailey is to investigate possible backflow issues and to give a report on the problems that might arise if this manhole were sealed or raised at the 9/29/05 Sunapee Commission meeting. Gus suggested that Sunapee come up with a plan and make a recommendation in writing to be included in New Londons report to the AGs office. 3. GEOTUBES: Gordon presented an update to the entire Joint meeting about the work of the subcommittee. The Boards had agreed up to expend $10,000 on a pilot project with regard to Geotubes. Subcommittee members include, Gordon, Dave Bailey, Dave Montambeault, and Charlie Smith. The Committee has had two meetings: one to brain storm and one to meet with Jim Meagher, from MPS (Material Processing Services, LLC) representing Geotubes and Tom White from DES. After tracking down Jims proposal, it does not cover everything and is slightly over $10,000 for what it does cover. Tom White from the State commented that while he felt the Geotube might cut the costs 40%, it would affect only the transporting not the disposal. Tom also felt that the biosolid would not be Grade A because of vectors and plastics. Tom reported that this pilot project need not be permitted. He would not put anything in writing until the project was designed by a P.E. Dave Bailey was told by Sunapees Town Manager, that a letter would be coming from DES stating they could do whatever they wanted within the gates of the treatment facility. Dave Montambeault objected to paying an engineer to design anything. Ed Rushbrook stated for the record he supported the idea of a pilot project. Dave Bailey, since that meeting, contacted Gordon about a competing manufacturer representative, Frank Grant, from Blue River Tech (207-384-6009). Frank proposed one or two bags, placed in dumpsters. These bags would leach out the tail gate end into an appropriate channel. This way you would not have to dig up anything or open the bags. It was felt that evaporation is not critical to drying, so it did not matter whether the bags were covered or not. Dave Bailey felt the bags could go to RMI but could not answer at what cost. Dave B thought a dumpster could be purchased for $5000. An agreement was reached that Blue River Tech needed to supply the Town of Sunapee with references and that the subcommittee should try to come up with a cost analysis for the dumpster idea. Gordon concluded by stating Newport is using digested material in their Geotubes and Sunapee should not use Newport as a yardstick. Ed Rushbrook confirmed this. Woodstock, the other community in NH that is trying Geotubes has sludge similar to Sunapee. Woodstock has not yet opened their bags because they are too wet after 18+ months. Ed when asked what other methods of sludge thickening or dewatering exist stated that either belt filter presses or centrifuges could be used, but that Sunapee Plant capacity would not fully utilize the capacity of the minimum size unit available for many mechanical systems and they would all cost a minimum of $100,000. The pilot project will need more review. Sunapee will be holding their regular monthly meeting next Thursday, Sept 29, 2005. New London will send a representative. Sunapee will look into the status of their permit and will hope to pull a lot together at the next Thursday meeting. Next Joint Meeting: Thursday, December 15, 2005 in Sunapee at the Town Offices.
