Hypothetical speaking, yes you can replace your own drain field but it is unrealistic. A drain field replacement requires a large labor force, construction vehicles and tools, city permits and ecosystem repair. Trying to do all this work single-handedly is nearly impossible and would take months to complete. A professional contractor is required for the accomplishment of the job.
How much does it cost to replace a drain/leach field?
Like previously mentioned, the drain field is one of the most expensive parts of the entire septic system. To perform any type of replacement a construction force is necessary, city ordinance must be paid, and environment laws must be followed. The whole process can amount to $5000-$20,000 dollars. Soil type will determine on which end of the spectrum the price to replace your drain field will land on. Porous soil conditions require a much smaller drain field, compared to an area with poor soil conditions. Meaning a smaller drain field is cheaper than a larger one. Another factor that affects price is “installation versus replacement”. On occasion, some homeowners feel it is more affordable to install a new drain field, than to repair the older one. Hiring a contractor will help facilitate the choice between installation versus replacement, and give a more accurate cost on obtaining a drain field.
