A greenhouse sewage treatment center

Via Phila of Bouphonia's Friday Hope Blogging, look what the people of Weston, MA did:
In 1997, the businesses located in the town center of Weston, MA were required to upgrade their sewage treatment system. The majority of these businesses, including the Omni supermarket and 30 others, chose a solar aquatic system that was later constructed by the Ecological Engineering Group. The natural waste treatment plant had tremendous advantages over other, traditional options. Who could refuse a cheaper, cleaner, odorless, aesthetically pleasing system that could treat all your waste?

When switching from the old waste treatment system, considerations included, cost, appearance and odor. The old waste treatment system cost 11 to 15 cents per gallon of waste treated, compared to the natural system, which costs merely 10 cents per gallon. This reduction in cost per gallon seems to be common after switching to natural systems. In Poughkeepsie, for instance, a newer reed bed operation costs 3 to 5 cents per a gallon, whereas the older mechanical systems cost 7 to 15 cents.

Weston’s solar aquatic system cost between $700,000 and $750,000 to build. Ten years after its construction, the treatment center is still in great shape; the pipes are going to be replaced for the first time in the near future.
