👉 A drainfield is a type of water storage system that uses gravity to extract and store water. It consists of two components: a main body with a pump, and a secondary chamber that collects any excess water from the main body. When the primary chamber empties, it sends water up through the secondary chamber into the ground. This process continues until all the water has been extracted and stored in the drainfield. The water then returns to the main body via gravity, where it is discharged back into
