B2C Underground Water Storage Tank Rainwater Harvesting Landscaping Drainage System 5000L from B&Q

B2C

Retention and infiltration system:Principle of operation: rainwater flows down drain pipes and is collectively transported to an underground rainwater filter or goes to a basket filter placed directly in the tank. The rainwater is stored in the tank. Only when it is full, water flows into the infiltration system. Only water that does not fit in the tank goes to the rainwater infiltration system. Absorbent wells are used for storage and then infiltration of accumulated water in the ground. They are used to drain rainwater from the roof and sewage water from household biological sewage treatment plants.They are usually bell-shaped without a bottom, with holes in the lower part.The water is infiltrated through layers of gravel of appropriate granulation. The infiltration well can be used in permeable and poorly permeable soils only if the distance between the bottom of the well and the groundwater level is not less than 1.5 m.The location criteria for absorbent wells are analogous to the conditions provided for the use of traditional drainage systems. When determining the dimensions of wells with a circular base, the area of ​​the bottom and walls of the excavation is taken into account as the total filtration area.In accordance with the adopted law, rainwater is considered sewage, and therefore you have to pay tax for its discharge. However, it is worth taking care of the use of rainwater. An absorbent well works best for this purpose. Thanks to it, you can easily drain water to the level of permeable soil. This translates into many benefits, especially when the well is part of household sewage treatment plants.All tanks come with lids and filtration systems. 110mm connections.
