Biological Recycling Of Wastewater
As the world population is continually increasing, the supply of fresh/potable water is steadily decreasing. The fresh drinking water used in our household from the mains water supply is one of the most precious natural resource of the earth and must be saved by each of us.
Preserving water has become a very important issue for domestic, commercial, industrial and other water users. In recent years many efforts have been put into preventing water pollution in all EU countries and word wide. Implementing ecological sanitation has been growing in importance in many countries. This concept is designed to provide environmentally friendly, economical and hygienically safe solutions to recycle wastewater, which is turned back into the natural chain of the ecosystem as nutrients and water. Each system is tailored to the needs of the users and has as objectives; to prevent the pollution of ground and surface water, to reduce the health risk of contaminated water and transform the potential energy of solid waste into biomass and biofuel or convert the waste into nutrients which go back to the land.
Wastewater from kitchen sink, dishwasher, washing machine, bathroom sink, and shower is called grey water. The wastewater from toilet is called as black water.
Grey water from showers, bathtubs and bathroom sink can be collected and used for flushing toilets. Using an efficient system, grey water can be used safely within 24 hours from collection; after that the system flushes the water out (because the bacteria build up). An average household can save about 30 % of the water use and also reduces the demand on conventional water supplies.
Grey water can also be used for watering the garden but with some precautions such as; grey water should be applied, if possible, below the surface or under the mulch. It is also important that the grey water doesn't contain toxic elements such bleaches, cleanser, detergents. Using household biodegradable soaps and detergents, and other natural products it will reduce the impact to the environment.
As part of sustainable living, we can recycle human waste using other environmentally friendly alternatives to deal with sewage.

Wastewater can be used for producing Biomass, Biofuel and Biogas.
There are many homes in remote areas where there is no suitable water supply, or mains drains and suffer from water shortage, installing a composting toilet is one of the green alternative you can implement.
There are two basic kinds of composting toilets;
1. Evaporating, Dehydrating Toilets, (or called as moldering) are dry composting toilets systems which remove the water from human waste. One method is to use the sunlight and wind to dry human waste and other method use electricity to generate heat and drive a fan for ventilation. Modern dry systems installed indoors use solar powered ventilation for drying the waste. After the waste is transformed into a dried, neutral and odor free material, this can be used as an ecological garden fertilizer for your flowers.
2. Thermophilic Composting Toilets are dry toilets which use a predominantly anaerobic decomposition process to treat human waste. Modern designs of sustainable composting toilets are using solar energy to provide the necessary heat to keep the compost at a high temperature. This system is very efficient to kill human pathogens and parasites within the waste.
All composting toilets use a small non-offensive organic material to cover the waste after each time is used. Materials like sawdust, straw, hay or garden refuse are ideal to create an odor barrier, absorb liquid in the compost and help the aerobic process.

If a composting toilet is not the appropriate solution for your needs than you can simple install an Eco-toilet. These high efficient eco-toilets are using a very small amount of water and reduce the utility bills as well.
