to get water from ground, drill a hole about an inch diameter so long pipe can be inserted. if you can get good water within 9 meters, that's great because standard pump can suck up to 9 meter down. if you get salty, rusty, smelly colored water, drill deeper. 30m is pretty much max depth for home-use jet pump and normally you get clean water. you can get deeper too and use bigger hole too; however, that's when you need permit. industry and hotel often do because they need a lot of water very fast. water collected from pump can be stored in large tank above roof. then gravity plays it part delivering tank-water. there's a switch on the tank that cuts electricity to the pump when a buoy inside the tank float up to a certain level. so, my switch is simpler water-level-based, not pressure-based. from empty to full, my pump runs about 30 min. my pump is 1 horse power or about 750w. so for a month that would be 30 * 30/60 * 750w = 11.25 kwh. for disposals, my house get two lines. one for washing, bathing, etc and that goes to city sewer. another is for human waste that goes to house ground sewage tank. sewage tank is basically an unsealed empty space inside ground. bacteria decompose human waste and the water just get filtered by ground beneath. the tank gets full over time and sewer tank service can come and suck the sewage tank.
