1, the water storage tank should have strict anti-leakage measures to prevent water seepage or groundwater infiltration.
2. The design of the water storage tank should ensure that the water in the tank often flows, and there can be no stagnant flow and dead angle, because waterproofing will lead to deterioration.
3. Generally, the water storage tank is divided into two compartments, which can work independently and exhaust air respectively, which is convenient for cleaning and maintenance. When the fire pool volume exceeds 500m3, it should be divided into two parts.
4. When domestic or production water and fire water share the pool, measures should be taken to prevent fire water from being misappropriated, such as setting overflow pipes on the suction pipes of non-fire water pumps or setting vent holes at the fire water level.

The diameter of the overflow pipe should be determined according to the maximum flow of the drainage pool, and it should be one size larger than the inlet pipe.
7. Storage tanks should be equipped with air pipes. The height of vent pipe of outdoor storage tank is generally 0.7~ 1.2m, and the diameter of vent pipe is generally 200mm.8 The water level signal of storage tank should be reflected to the pump room and fire control room in time.
9. waterproof casing shall be set for the pipeline crossing the water storage tank wall.
10. When the storage tank is adjacent to the building, measures should be taken to prevent the pipeline from being damaged due to uneven settlement, such as using metal hoses, rubber joints and other facilities.
1 1. Water storage tanks in cold areas should be insulated.
12, the storage tank should be arranged in the basement or near the outdoor pump room.
13, the water storage tank shall be provided with a suction pit, and the depth of the suction pit shall not be less than1.0m. 。
