The fact is, not all sewage systems need to be upgraded. If your septic tank is structurally sound and the percolation area is fit for its purpose and there are no pollution issues then you don’t need to worry. However if it’s the case that the septic system works poorly you may need a new percolation area or possibly a complete upgrade by means of a newly designed sewage treatment system and percolation area.
