Sewer is a system of pipes used to transport human waste away from the any built up community. In rural areas where houses are spaced so far apart that a sewer system would be too expensive to install, people install their own, private sewage treatment plants. These are called septic tanks. A septic tank is simply a big concrete or steel tank that is buried in the yard. The tank might hold 1,000 gallons (4,000 litres) of water. Wastewater flows into the tank at one end and leaves the tank at the other.
