Business, institutions, and apartments where there are many people also use lots of water. A lot of greywater is generated and can be used in several outdoor irrigation activities. The use of greywater from these institutions requires a complex system before the water can be reused. Typically, these systems are made of large temporary tanks, filter system and water disinfection system. The water can then be used to supply water for drip irrigation or to flush the toilets.

131In many organizations, it makes more sense for the organization to treat both the greywater and the blackwater together rather than separating the water. In many buildings, the water systems are combined with the same drainage system. All the water can be treated on site and reused in the toilets or the cooling systems. There is a system called the membrane bioreactor that enables organizations to collect and treat, and then reuse the treated water. The system reduces the need for fresh water by a half and decreases the energy costs by a similar margin.

Other commercial entities use the living systems to treat the waste water. All the water that is generated in buildings that use the machines is recycled after treatment. Most buildings can save sixty percent of the water they get from the city authorities.


Industrial organizations can invest in small water treatment plants and incorporate the wetlands or greenhouse projects to reuse the water. The water can also be used in reactors of some of their cooling plants. The water is also good for use in non-portable needs.

An ideal commercial water treatment plant should enable the organization to maximize the use of the wastewater for all essential activities safely. The system should be able to disinfect the water to a high percentage eliminating any possible infections to people that come into contact with the water.

A good filtering system also works on the watercolor to ensure that the water looks good. The maintenance and the running costs of the treatment plant should not be very high that it undermines any savings made on the water costs.

If may organizations invested in the water recycle technologies; they will lower the pressure on the available freshwater sources, and there will be enough water for other needs in the community. The management of such firms can learn from the Open permaculture school and regenerative leadership institute, founded by Vladislav Davidzon on various proven methods of recycling wastewater conserving and protecting the available water resources.
