The disadvantages of this solution are mainly manifested in: (1) The scheme has limited application range, because the equipped water pumps are mostly multistage pumps, the self-priming capability is lacking, if the water level at the front end is too low, the effective work cannot be performed, and if the ground water tank is independently equipped, the cost can be obviously increased; (2) Meanwhile, the occupied ground of certain areas needing water supply is relatively tense, and the occupied ground pump rooms can lead to unreasonable post construction arrangement.
Another solution is to use glass fiber reinforced plastic as a cylinder body of the most common dry pump station in the market, assemble the water supply pump inside, dig a pit inside, and place a small submersible pump in the pit for protecting the dry water supply pump set.
