The root cause of the problem of sewage in our rivers is not a matter of how well we operate wastewater treatment facilities, nor is it flooding brought on by increased stormwater. The root cause is that we treat sewage as waste and not as a resource, because, if we did, we would not dispose of it, but recycle, i.e. compost, it. Composting is best done as close as possible to the source and point of final application. People should, wherever possible, compost their excrement hyper-locally.
Other than the general public and wildlife, the beneficiaries of adopting humanure composting would be gardeners and foresters. Humanure compost can be used wherever standard compost is used, provided it is made with care pertaining to temperature and curing time. It is also a good fit for biochar.
Culturally, there is a great challenge to getting USAnians to adopt humanure composting. One of the precepts of social marketing is that culture trumps strategy, so adaptation to culture is necessary in all cases. The audience to target in this campaign is going to have to be avid composters who have no worries about personal injury liability stemming from their methods and inputs. Not that thermogenically composted humanure is unsafe, it's just that most here can't shake their fecophobic preconceptions.
