On the surface, the $1.3 million state environmental grant for the Springs School to install an up-to-date septic system appears to be an important step toward improving the quality of nearby Accabonac Harbor. The school has long struggled with an old-fashioned and partially failed wastewater system. Recently, it has had to do costly pumping as often as every 10 days during the school year. There is no argument against updating the wastewater system. What is not entirely clear is whether newer technology will work at a school-size scale and if it will lead demonstrably to a cleaner harbor.
