Underground rainwater harvesting tank is our main product. And we always use this rainwater tank to build underground tank system, such as rainwater infiltration system or attenuation system.
Though there’s above ground rainwater harvesting system, underground rainwater harvesting tank system has many advantages.
First, we can reuse the space above the ground, such as for parking lot, a solar energy generator system, or plant trees or grasses as green belt, or for a playground for children or playing ground, stadium or golf course, etc.
Second, it is suitable for build very large system to collect and store huge quantity of rainwater. The above ground rainwater tank will take up a lot of spaces on the ground, which we could not reuse it again.
