Water scarcity is an upcoming disaster that is going to impact the world real significantly. Techniques such as gray water and rainwater harvesting are strategies that can help the world mitigate this challenge. In an average commercial residential building, thousands of gallons of water are wasted every year. Capturing greywater from the showers and lavatory sinks can prevent this waste and save money as well.
What is Gray Water?
Gray water is water that has been “gently used”– usually as water from showers and sinks, but could also be sourced from ponds, pool backwash or process rinse water. Toilet wastewater and kitchen sink wastewater is termed “black water” and is not normally considered for harvested water systems.
Uses of Gray Water
Gray water is most often harvested to flush toilets in a building, but the cleaned water can also be used for irrigation and other applications. The proper treatment makes the water safe for these non-potable applications.
Benefits of Gray Water Harvesting System
- Reducing the use of fresh or municipal water.
- Saving on water bills.
- Reducing the load on the municipal sewage system.
- Helps to save a valuable resource, benefiting the whole community.
Gray Water Filtration System
For an efficient water filtration system, it is advisable to work with experts in the field. Professional water harvesting companies design systems that ensure the treated water is safe to use. The design firm should be proficient in gray water filtration and sanitation, and third-party certification is recommended.
