Rainwater collection tank with a manometric water level indicator

Description: Cylindrical tank for collecting rainwater, mounted in place of the downpipe of the system collecting rainwater from the roof of the building, 3 to 10 m high, with a manometric indicator of the amount of accumulated water, intended especially for temporary water storage in order to limit its outflow and use for watering plants in the garden in dry periods.

Nowadays we observe in Europe periodic droughts almost every year, resulting in a reduction in the activity of green areas. Despite the significant deficit of water, its resources are not used rationally. Most of the rainwater is discharged through the sewage system into rivers. Taking it into account, it is justified to install rainwater collection tanks wherever possible. Accumulated water may be rationally used, especially for watering plants in dry periods and in sanitary installations in periods of heavy rainfall. The tank for collecting rainwater according to the utility model has a cylindrical shape and has an inlet stub, an overflow pipe, revisions and a drain valve, intended to be placed in the place of the downpipe of the rainwater collection system from the roof of the building, and the tank's coat is covered with an insulating layer of polystyrene or mineral wool with a thickness of 10-15 cm, and in the lower part of the tank, at the level of the drain valve, a pressure gauge is mounted to measure the water pressure. The measuring range of the manometer is adapted to the height of the tank. For the height of 3-6 m, it is from 0 to 0.6 bar, while for tanks with a height of 6-10 m, it enables measurement in the range from 0 to 1.0 bar. Considering that the pressure of a water column 10 m high corresponds to a pressure of 1 bar.
