Commissioners Meeting
October 5, 2016
The Board of Commissioners met at 10:00 am on Wednesday, October 5, 2016. In attendance were Commissioners Ron Sandstrom and Larry Leonard. Also in attendance were water operator Ian Hayes, SCADA programmer Tom Therrien and Engineer Nick Sceggell.
At 10:10 am the meeting was called to order by Chairman Ron Sandstrom.
Ron Sandstrom makes a motion to call Commissioner Mike Smith for participation in the meeting telephonically. Larry Leonard seconds the motion and the motion passed 2-0. Commissioner Smith joins the meeting.
The analysis of the data logger information regarding the drop in water pressure to no flow at 1 Bristenstock and 19 Blinden is discussed. Engineer Nick Sceggell outlines the review of the data and the model of the system that is used. Some updates to the model logic were implemented during this analysis so as to duplicate the pressure loss. Additional updates that would have the model fully simulate the actual usage in all zones would be beneficial. Additional metered information would be needed. Ian Hayes discusses the connection outside of Jungfrau station that feeds Appenvel and enters the Reinach zone. Nick Sceggell states that this connection would be of benefit to Bristenstock, not a detriment. A full analysis of the friction loss within the Jungfrau to Reinach forced main was potentially not fully calculated. Muddy Beach as a factor for pressure within the distribution system is discussed. Data shows pressure loss occurring dramatically when Oak station begins to pull water for the Chocorua tank and neither Muddy Beach nor Jungfrau is pumping. Having Muddy Beach turn on prior to the Oak station turning on is discussed as a potential means of offset for the pressure loss at the far ends of the water lines; as would having Jungfrau run with Oak. Validation of the pressure under specific pump scenarios is needed.
Protection for the temporary service line currently feeding 1 Bristenstock is discussed. Corrective actions to keep the pressure loss from occurring may allow the house to be reconnected to the original service line. The temporary line could be blown out and left in place for the winter should it be needed.
Ian Hayes will perform a test for validation by collecting data logger information while running Oak without Muddy Beach or Jungfrau; running Oak with Muddy Beach; running Oak with Jungfrau. The data loggers will be collected following each testing phase and the information sent to the engineers. Final corrective actions will be implemented using set points within the SCADA system.
At 11:45 am Ron Sandstrom makes a motion to adjourn the meeting. Larry Leonard seconds the motion and the motion passed 2-0.
