C3 - Waste Water
Relates to Healthy Living Practices:
- removing waste water safely
- reducing the negative effects of animals, insects and vermin
- reducing the impacts of over-crowding
Waste water or sewage contains germs, also known as pathogens that can be very harmful to people’s health. Systems that remove waste water from the house, treat it and dispose of it safely are critical items of environmental health infrastructure in any community.
Increasingly, waste water in rural and remote communities is being treated and disposed of in off-site sewerage schemes that collect both the grey and black water from houses and treat and dispose of the waste water in a centralised facility. The advantage of an off-site system is that all waste water is removed from yards and living areas and handled at one place away from people, and the operation and maintenance happens in one place rather than in every yard in the community. A disadvantage is that the system can be more expensive to operate than onsite systems such as septic tanks.
