Shenzhen Rain Doctor is a company specializing in the production of geological cell modular rainwater collection tank systems (infiltration tanks/attenuation tanks/infiltration tanks). It was established in 2013 and has two large factories in Songgang, Shenzhen. We are the first rainwater harvesting system manufacturer in China, we have 10 production lines, more than 20 engineers in R&D department and about 300 skilled workers.

We have our own mold design and making workshop, all injection molds for producing soaking water tanks are designed and manufactured by our own workshop.

With a production capacity of over 1,600 cubic meters per day (or 50,000 cubic meters per month), our rainwater harvesting tanks can meet the needs of any large-scale rainwater harvesting project.

We are a third-level construction contractor with national qualification, which enables us to carry out the construction of rainwater harvesting systems in China, and we have completed more than 500 large and small rainwater harvesting system projects.

Now our company can provide a complete set of rainwater collection system accessories, including rainwater sewage (silt, sand, garbage collector) interception basket device, initial rain removal (discarded sewage flow) device, rainwater automatic filter, Soakaway Crates, Inspection Chamber (Inspection well), pipe connection box. All these accessories are made by ourselves.

Our company has passed the following qualifications: ISO9001:2015, ISO14001:2015 and OHSAS18001:2007.

Doctor Rain's rainwater tanks can be used to build underground rainwater tanks of any size according to different purposes, which can be used for rainwater storage, infiltration, attenuation, retention and retention, so rainwater tanks can also be called infiltration tanks, infiltration tanks or retention tanks, retention tanks and Attenuation box. It is the main part of the rainwater harvesting system.

What is a Rainwater Harvesting System? A rainwater harvesting system is a system that helps us collect rainwater and store it or infiltrate it into the ground. What are the components of a rainwater harvesting system? Building roofs, hardened anti-seepage pavements, etc. generally have rainwater collection areas, intercepting large particle filters, initial rainwater removal devices (also known as initial rainwater flushing filters), automatic rainwater filters, geotechnical combined rainwater tanks, if you need to repeat To use rainwater you need geotextiles and geomembranes and some pumps to get water from the underground tank, if you just want to infiltrate rainwater into the ground you only need geotextiles.
