The term water recycling is generally used synonymously with water reclamation and water reuse”

Introduction

• Water recycling mainly refers to reusing waste water such as from residential, industrial places, agricultural irrigation, etc. to implement in something beneficial. Water recycling offers a great deal of benefits for today’s generation as over use and waste of water led to fresh water shortage. This not only saves water but also saves money in different effective ways and the treated water becomes multi-functional.

The type of recycling also depends on the source of the waste water. “Grey water”, is the water which come from non-toilet plumbing, like basin, shower and taps. “Black water” is the toilet plumbing water. Water from kitchen and dishwashers are categorized as black water because they contain harsh chemicals, pathogens and grease.

“Recycled water can satisfy most water demands, as long

as it is adequately treated to ensure water quality

appropriate for the use”

So what basically happens is the water from the shower + the wash hand basin will be collected and then treated.

This recycled grey water will be used to flush toilet..

This reduces waste

Grey water system

As we see from the picture , black water is not easy to reuse, it has to go through a lot of processes to get treated unlike grey water which can be reused if the grey water system is stored in the bathroom.

Where it can be used

• Toilet closet• Sink• Basin• Shower• Bath tub• Any furniture piece that uses water

Installation methods

Benefits

• By recycling water, we conserve fresh water for sensitive aquatic lives. Certain aquatic plants, animals and fish depends on natural and adequate flow of water, which when disturbed, pushes these lives to extinctions.

• Recycled water can be used for creating or enhancing wetlands. Wetlands keep a major role in wildlife and wildfowl habitat, water quality improvement, flood diminishment, and fisheries breeding grounds, etc.

• Irrigation lands where recycled water is used do not need extra chemical fertilizers due to the presence of certain nutrients in the waste water. The black and grey waters are filtered specially for irrigation in a way that it is partially filtered, allowing plant friendly microbes to remain.

• The cost efficiency and fresh water conservation because of recycling water is significant.

• Important by-products like electricity and soil amendments, are also generated during the water recycling process. For example, the recycled water goes through turbines, which rotate at high speed, converting mechanical energy to electrical energy.

• Public areas such as parks, golf courses, schools, and roadway greenbelts stay green, which enhances the quality of life for communities and cut down the amount of pollution going into waterways.
