Pros and cons of greener waste systems

As an alternative to traditional septic tanks, new alternative septic systems offer green advantages:
Alternative systems add a step to the filtration process with materials like sand, peat moss, sponges, or textiles; aerobic treatment units, which use compressed air to break down organic matter; and other technologies that result in cleaner discharge, or effluent, being dispersed on the drain field. The result is less pollution leaching into the groundwater.
But they can be mixed blessings.
The problem is that these new systems are often quirky, demanding frequent inspections and maintenance to avoid leaching effluence into groundwater, which is typically the source of drinking water in these rural areas.
