Water plan house output In this chapter we are going to investigate the output of the water. First we start with the output ways: 1- grid 2- regeneration area 3- a piece of field on the yard 4- septic The quality of the output is important as well the quality of the pool filtering. quality output 1. In the kitchen there is detergent, soap oil butter as residue. There are the dirty pots and pans. Most of it will be cleaned with kitchen paper or dropped in the basket; 2. In the bathroom and fountain there is soap, toothpaste and shampoo; 3. Next to the fountain there is soap; 4. Soap for cleaning the house and windows. On the market there are mild biodegradable detergent, soap and shampoo. The output of the toilet is still in discussion. I prefer a toilet which is not using water. I am not a fan of septic or let it flow into the field. Although I haven seen beautiful projects where the end product is drinkable. The alternative toilet is in full swing. Next we have the garage. In the garage most of the products are chemical and has to go to an waste landfill site or recycling place. quality pool area The question is now if the pool area can cope with this end products. The different kind of soap product are natural but has phosphates in it. In general phosphates create algae. The water will be murky and the quality of the water will be toxic over time. I found an article that the mild biodegradable products has so little phosphate that you can poured it on the grass. https://www.conserve-energy-future.com/smart-easy-ways-to-reuse-wastewater.php For the pool area I wrote that I will use three types of filtering. From these types, Technical wetlands (TWL) and Biofilm-accumulating Substrate Filters (BSF) reduce phosphor.
