We are building a 5-Story office building with two bathrooms on each floor. We want to recycle the Grey water from the sinks. There are no kitchens, or laundry facilities-the gray water is only from wash basins in restrooms.
My question is: can we use the water directly from the sinks for irrigation, or do we have to filter it first. I have seen grease traps and sand filtration techniques used for other gray water treatment, but because our water is only from hand washing, I am under the impression that I do not need a filtering system. The irrigation would be for trees and bushes in the front of the building, and creeper vines that will grow along the walls of the building.
We want to build economical and environmentally friendly water conservation/recycling systems. We basically wanted to know what we could do, and what the general costs would be for installing a Grey Water system.
