"What is a storage tank?" I have compiled a collection of questions!
A retention tank is a facility that temporarily stores a large amount of water and allows it to flow out gradually through a special outlet. It plays a role in protecting cities from flooding damage caused by heavy rainwater from typhoons and sudden downpours. 【Part of the questions】 ■ What is the difference between a retention layer and a water storage tank? ■ Can the inside of a retention tank be cleaned? ■ Is it possible to remodel an existing retention tank in a facility? ■ Is the retention tank resistant to earthquakes? *For more details, please refer to the PDF document or feel free to contact us.
