Description

How to make a water storage device

technical field

The invention relates to the technical field of water storage devices, in particular to a method for manufacturing a water storage device.

Background technique

my country's freshwater resources are more in the south than in the north. According to the distribution of freshwater, most of the measures currently taken are south-to-north water diversion. Although the south-to-north water diversion has alleviated the shortage of water-scarce areas, the cost of water transfer is relatively high. In order to ensure the residents' basic living water, the government needs to spend a lot of money to subsidize it, which has cost a huge amount of money. Although residents' domestic water can be guaranteed through the above measures. Once there is a drought year, if the plants are not watered, it will affect the grain output. In order to prevent crops from dying due to drought, farmers mostly dig wells in the fields to pump groundwater to irrigate crops. There are many disadvantages in extracting groundwater. For example, the cost of extraction is high, which brings economic burden to farmers. Another example is that groundwater resources are limited. Long-term extraction will cause surface subsidence and pollute groundwater.
