Hi there in my opinion as much as a third of new development in the United States relies on decentralized wastewater treatment. Such systems pose a threat to shorelines and drinking water. They can also allow development to occur in places and at densities that are in conflict with a community’s vision for its growth. Hey I have good news for all of you I found the website on net in which all types of water treatment process it helps me if you were interested visit the website which is given below.

You need reverse osmosis, excellent filtration, triple distillation methods, anti mold tanks to hold the water such as 308 or better Stainless steel, as well as all the piping and transfer methods should also be high grade Stainless steel.

Also you need a highly structured and well followed maintenance schedule.
