Are there any environmental advantages to decentralized services?

Decentralized servicing is the environmentally preferred option over individual/septic services in rural and small communities. One decentralized well, and one decentralized septic that are licenced and monitored by the Province, versus several individual wells and septic systems that are not monitored, will provide better environmental protection. Natural supplies of water are dwindling. And the one truly consistent long-term, sustainable source of water is that which can be processed and reused. Decentralized systems have the ability to reuse water safely and effectively.
