Rural areas are all self-built houses. Although you can establish your own style, you still have to consider some issues. Tap water supply is particularly convenient in cities, but it needs to solve the water supply problem in rural areas. This will involve some problems of installing water towers for self-built houses. The water tower is mainly used to store water. It is very convenient to install the water tower to turn the water in the well into tap water. In our countryside, the groundwater is rich and the water quality is good. Every household has installed a water tower on the roof to store water, and then installed a small water pump next to the water tower, which makes the family more stressed and water use much more convenient.
