A leach field is a crucial component of a septic system, responsible for removing impurities and contaminants from wastewater. Over time, leach fields can become clogged or fail, leading to septic system issues and potential health hazards. Changing a leach field is a complex and time-consuming process, but with careful planning and execution, it can be successfully completed. This guide will provide a step-by-step walkthrough of how to change a leach field, ensuring a hassle-free and efficient experience.
Step 1: Assessing the Situation
Before embarking on a leach field replacement project, it’s essential to assess the situation thoroughly. Signs of a failing leach field include slow drains, sewage backups, and foul odors around the drain field area. If you suspect a leach field issue, contact a licensed septic professional for a diagnosis and evaluation.
Step 2: Planning and Permitting
Once the need for a leach field replacement has been confirmed, you’ll need to plan and obtain necessary permits. This involves determining the size and location of the new leach field, as well as securing approval from local authorities. The size of the leach field is based on factors such as soil type, wastewater volume, and local regulations.
Step 3: Excavation and Installation
The next step is to excavate the area where the new leach field will be installed. The excavation depth and width will depend on the design and size of the leach field. Once the excavation is complete, the new leach field pipes and gravel are installed according to the approved plan.
Step 4: Gravel and Pipe Placement
The leach field consists of perforated pipes that are surrounded by gravel. The gravel provides a surface area for wastewater to disperse and allows it to percolate into the soil. The pipes are typically made of PVC or ABS and are laid in parallel rows, connected by a distribution box.
Step 5: Soil Replacement and Grading
After the leach field pipes and gravel are in place, the excavated area is backfilled with soil. The soil should be compacted to ensure proper drainage and prevent settling. The area around the leach field should be graded to direct water away from the system.
Step 6: Restricting Access and Landscaping
Once the leach field is installed, it’s important to restrict access to the area to prevent damage. This can be done by installing fencing or planting vegetation around the perimeter. Landscaping can also help to enhance the aesthetics of the area and improve drainage.
Step 7: Maintenance and Inspection
Regular maintenance is crucial to ensure the longevity of your new leach field. This includes pumping the septic tank regularly, inspecting the leach field for any signs of failure, and addressing any issues promptly. It’s also recommended to have a septic professional inspect the system every three to five years.
