Keep current marine system
Since the sludge created by land-based sewage treatment is a challenge because (it can contain) a concentrate of very small amounts of heavy metals and other chemicals, it’s far better to avoid the whole problem by keeping our current marine-based sewage treatment system. The effluent is very sustainably dispersed and then degraded into stable compounds in the Strait’s active marine environment.
