Gray waters

Published on by in Social

Can anyone suggest treatment methods for gray waters for isolated homes? Where normally live small families since 1 to 5 people.

 

That's a great problem with small volume. People living where the public systems don't arrive must preserve their water fonts, lakes and rivers.

  2. HelloRick, For isolated homes, simple gray water treatment methods can effectively support small families (1-5 people). These methods usually include settling tanks, gravel filters, and reed beds. First, a settling tank separates heavier particles. Next, the water flows through a gravel or sand filter to remove finer particles. Finally, a reed bed (a shallow, plant-filled area) uses plant roots and microorganisms to further cleanse the water. This treated water can safely be reused for non-potable purposes, like irrigation or flushing toilets. Using these methods helps reduce waste, preserve local water sources, and maintain a sustainable, eco-friendly household.

  3. Hi Rick, we live on a small holding that does not have a municipal sewer service.  What we have done works very very well.  We drain the grey water (and incidentally the septic tank outflow) into a re-purposed tank just below ground.  In there there is some separation of solids, with the overflow then distributed into a small vertical flow wetland (it is about 8m x 2.5m and 1.6m deep, lined with a hdpe lining - in our case also re-purposed).  the outflow from the wetland drains into a final tank where we have a submersible pump activated by a float switch which pumps the water to another header tank that feeds sprinklers in the garden.  As an additional treatment stage (not 100% necessary) we circulate the water in the first tank through a bed of  fish filter media (approximately 1m3) to allow an aeration stage and convert the ammonias to nitrates, some of the nitrates being denitrified when the water is nreturned to the tank which is in an anoxic condition.  we have 2 families including a small business living on the premises.  The final effluent is odourless. Hope this helps.

  4. Hi, We are based in india and are building a solution for exactly the kind of use-case you are talking about. I would love to understand the segment needs better. Would you have some details on what kind of homes are these, vol of water, current water tariff, acceptable cost of system, etc.

    Happy to collaborate with you on the solution.
