Rainwater storage, as the name suggests, is a container for storing rainwater. Today, there are rainwater storage tanks such as rainwater tanks, rainwater tanks, rain storage, rainwater storage, and underground rainwater storage, etc.
For rainwater storage, Three conditions.
(1) absolutely no water leakage;
(2) The material of the container must be free of water soluble and contaminating water,
(3) Containers should be covered to avoid falling into the dust and water evaporation; container structure should facilitate internal cleaning.
If the above conditions are met, it is a qualified rainwater reservoir. Rainwater reservoirs of different shapes, materials and constructions can be used depending on the use of the rainwater, the structure of the building, the storage conditions and the place of installation. Some places can only be installed on the market to buy finished products storage, such products both to the site assembly, but also in the field of production. If you install the water level gauge in the reservoir, use more convenient.
In the past, water tanks, rain water storage containers and drums were commonly used as rainwater reservoirs. Large containers (500 liters or more) are mostly steel, stainless steel or reinforced glass fiber reinforced plastic (FRP) and other materials assembled into the water tank; a larger container on the container (less than 500 liters); Use a reinforced concrete structure for the sink. But also to strengthen the glass fiber reinforced plastic tank modified to do with the case of rain water storage.
Some countries with little rainfall in the dry season often use local materials such as wood, steel, concrete and plastic, and almost always produce cylindrical reservoirs on the ground. In areas where there is no water supply system and no groundwater, domestic water including drinking water must be used for all the rainwater. Therefore, the method of removing rainwater from pollution and protecting rainwater should be adopted. At the same time, sedimentation Of the initial rainwater removal device.
