I <br /> i 4. Toni asked about some of their related projects, as listed in the proposal. <br /> x SEA said they are now working for MDC in west Boyloston and Holden, which provides the drinking <br /> water supply for Boston. They have developed a pilot program for innovative o _site technologies. <br /> Homeowners volunteer to have them-installed free of charge. They designed and are now building 1 <br /> pilot systems. They will collect data and evaluate then. <br /> They have worked with Cohasset on a septage management system. The torn will have to he involved <br /> o help manage them. <br /> They have worked with DEM on remote recreational facilities, for example installing composting <br /> toilets at bath houses at beaches. <br /> . Tom asked what work they did for New Seury' <br /> SEA said in 19.90 they designed 2 treatment plants with 3 specific discharge point. It seems like the <br /> exact location the Sewer Commission is looking at. They installed monitoring well at the 3 sites for <br /> groundwater flow, did groundwater sampling and 2 dimensional groundwater flow models and <br /> mounding analysis. <br /> Ir. Howes asked if their model was still on lime and if the modeler is still on staff? <br /> Unfortunately,the person passed away. They think they could find the model. <br /> . Worn said he is concerned about the effects on data of the seasonality of Mashpee's population. <br /> SEA said they have thought about that issue. They are familiar with the water District and think those <br /> records could he used to correlate water usage with flow rates. <br /> Torn said it seems the water district numbers complicate the issue. How would you account for <br /> I`rgatlon <br /> SEA said here are statistics about how much water gets returned to a sewer system. There is a lot of <br /> science on the connection between these two. <br /> 7. Tom said for phase IV of the scope, screening analysis of technologies; he envisioned an actual plan <br /> which is site specific. The proposal saws non site specific. <br /> Sea said they also envisioned that,the semantics are wrong. It will be specified as to where in the <br /> watershed and planing zones a particular technology applies. They will not however, identify who <br /> owns the lots referred to. <br /> . This proposal suggests combing 2 phases. <br /> SEA said they see this scope taking longer then 12 months. By combm' ng phases you reduce some <br /> time, save some costs. <br /> . Torn asked how they will get land use data from the other towns.`? <br /> They think MA GIS should have land use data for those com rnunitie . They will use estimates for <br /> population to get load and use census data. They did struggles with the requirement of alternatives <br /> with and without the participation of adjacent communities. They know the level of work that <br /> lashpee has done and what it would take to do for the other towns. You can take the more <br /> conservative approach and assume no cooperation from other towns. <br /> 9. Toni asked about setting up a Sewer District vs. a Sewer Commission. <br /> SEA said a Sewer District would be a political entity distinct from the town and not subject to town <br /> meeting action. This would get sewer projects outside of the competition of other town funding <br />
