Wastewater Superintendent Meader answered that the first batch has already been shipped. These are the duplex chambers going to the condos and the rest will come in 10 pumps. Chair Harris asked if any of the condos will be delayed until the grinder pumps arrive. Wastewater Superintendent Meader answered that the first delay is waiting for the approval letter and then, in Summerwood, Sea Oaks and Asher's Path, where there are gravity systems, they can start connecting. Four (4) of the units in Sea Oaks require the duplex grinder chambers and those would be the only ones that may experience a slight delay. Chair Harris asked if the system was ready to go. Mr. Drainville and Wastewater Superintendent Meader answered that the fire alarm system, the occupancy inspections have all been done. Mr. Drainville states that there needs to be 10% of the flow to sustain a biomass and with the three developments (Summerwood, Sea Oaks, and Asher's Path) that 10% would be achieved as they have been described as being sufficient in maintaining a healthy microbial environment. Mr. Drainville expressed that the three developments are important to get the system started but the importance to have others tie-in is that 10% is not enough to put the system through its testing and so having 50-60% is important for the Town to see that this equipment is performing adequately while under the 1-year warranty. Chair Harris responded that the 90- day hookup is important because if the number of hookups are not in place, then the system will not be functioning as expected. Mr. Drainville added that there is a warranty through the manufacturer and the contractor, which is one-year period so it is important to put the system through its testing with a decent amount of load coming into it and long-term confidence in the system will be obtained. Wastewater Superintendent Meader clarified that in order to get to the 50% - approximately 60,000 gallons per day, the first three developments bring in a total of 32,000 gallons a day (estimated off of their water use records).
