Answer:
1answer=Households may produce wastewater from flush toilets, sinks, dishwashers, washing machines, bath tubs, and showers. Households that use dry toilets produce less wastewater than those that use flush toilets. Wastewater may be conveyed in a sanitary sewer that conveys only sewage.drainge

Water from kitchens and dishwashers are also considered blackwater due to the contamination by pathogens and grease (Your Home, Australian Government defineBlackwater can contain feces, urine, water and toilet paper from flush toilets. Blackwater is distinguished from greywater, which comes from sinks, baths, washing machines, and other kitchen appliances apart from toilets. ... Blackwater and greywater are separated in "ecological buildings", such as autonomous buildings.
3answer=dry well or drywell is an underground structure that disposes of unwanted water, most commonly surface runoff and stormwater and in some cases greywater. It is a covered, porous-walled chamber that allows water to slowly soak into the ground, dissipating into the groundwater definesoak pit, also known as a soakaway or leach pit, is a covered, porous-walled chamber that allows water to slowly soak into the ground
4answer=Compost is made by decomposing organic materials into simpler organic and inorganic compounds in a process called composting. This process recycles various organic materials otherwise regarded as waste products. A good compost is rich in plant nutrients and beneficial organism defineComposting is the conversion of solid organic material into a humus like substance by controlled biological decomposition. Composting is the process of letting mother nature transform organic matter into a material with environmentally beneficial applications. The process is aerobic, meaning it requires oxygen.
5answer=The depth at which you reach the sewer line will vary. It can be as shallow as 18 to 30 inches or as much as 5 or 6 feet. In cold climates, the pipe will be buried deeper to prevent the pipe from freezing in the winter. But pipe depth is not always a matter of climate defineBuried piping is defined as piping that is below-grade and in direct contact with soil, whereas underground piping is below-grade, not accessible, and outside of
short of 5 isPipes don't float in the air on their own; they have to be held in some way. We often bury pipes to protect them and keep them out of the way, but the ground isn't always that good at holding pipes together. ... Today, we're talking about thrust forces in pipe systems. Designing systems of piping might seem intuitive.
