Leach Field Replacement Costs Two variables determine the cost of replacing a leach field: its size and the presence of contaminated topsoil If the pipes that deliver gray water -- the nonpotable water flushed from a septic tank -- to the leach field are merely cracked, you need only replace them Budget about $5,000 for this fix.
