[RI Swamp Yankee]

That looks similar to a system used by a business in Wickford RI which is very close to the water. The building had constant septic problems being so close to the water with no adequate place for a full leach field. They put the whole system in the basemant (big concrete chambers) The dispersion field is small and only a few feet from the water but what came out was clean enough so that is only needed a few feet (maybe 25 feet as I recall) to leach through the soil before reaching the cove. Testing proved the water out of the dispersion chamber was almost clean enough to drink.
