the water lines are pressurized so they just run lines to where ever there is a sink or toilet or faucet. Now the septic is all gravity flow. Where ever there is a drain (sink, toilet, toilet faucet) they start the line on the highest drain in the house. Then they run it to the next lowest and so on untill it falls into a septic tank or sewer
These are two separate systems, water coming in is either from a city water source piped in or a well of fresh water, septic water going out goes to a septic tank or city sewer service for treatment.
City water.
the sewer
only kidding
well or city water
The water that comes INTO your home comes from either a municipal water service, (city water), or is pumped in from a WELL, which is drilled outside of the home, (in the yard). If from the city, their whole system is pressurized to a fairly high degree, if it’s from your well, then the pump that pulls the water up from the ground applies pressure to the house system. It’s piped in underground, through the basement wall and pipes are run to every place you might need water, bathroom, kitchen, laundry room, etc. When you open a fixture in any of these rooms and allow water to flow into the sink or wash machine, or dishwasher, etc., it eventually needs to be let out and then it goes into a drain system. Nearly every point that has water service also has a drain, with a trap under the sink or bath lav, with the exception of a toilet, which has it’s own trap built in to the back end of the bowl section and a dishwasher, which is usually plumbed to drain into the kitchen sink system. They all have some sort of trap just below the water holding part of the service area, which holds a level of water which in turn stops the odors from coming back up from either the septic system or the city’s sewer system. A septic system works by collecting the household waste, usually mostly fecal matter, (human waste) and TP. Occasionally a home will have a garbage disposal in one sink and that will also be plumbed to go into the septic holding tank, (although it would be much better for the septic system if it went somewhere else). The system itself works by the action of the bacteria which accumulate in the tank and breakdown the solid portions of the waste deposited into liquid. The liquids are drained off into either a dry well, or a drain field, for dispersal back into the ground.
