Dry well installation costs vary depending on factors such as site conditions, location, and materials used. These costs typically range from $500 to $2,500, including materials and labor charges. The installation involves excavating a hole, lining it with filter fabric, placing the dry well, connecting perforated pipes, adding gravel layers, and backfilling the hole with soil. Contractors involved include plumbers for pipe connections, excavators for digging, and backhoe operators for filling. Crucial materials include the dry well, perforated pipes, gravel, and filter fabric. Industry regulations guide installation best practices, while maintenance involves periodic inspections and cleaning. By collecting and infiltrating stormwater, dry wells effectively manage runoff and provide environmental benefits.
