Welcome to Bonser & Son

Bonser & Son installs all types of septic systems and will fix any problems. If you have a failing septic system or have a question don't hesitate to call:

First we will determine why your system failed. If your sewer system is state approved and has lasted 15 to 30 years the best way to fix your failed system is to remove the old leach field by digging it up and replacing it with the same size and type of system. But if your system fails in 5 to 10 years or less then replacing it will the same size and type of system would not be the best solution. Sometimes a new design for a different size or type of system is more cost effective in the long run. There are a lot of different systems on the market, however if you have the room on your property, it is this installer’s opinion that the traditional stone and pipe system is still one of the best. If you need a smaller system because of space restrictions a chambered system, preferably cement, is always a great choice.

We always look at each system and land individually to determine the best equipment and approach to use to minimize as much disruption to your lot as possible. We also look at your system and location so that our price estimate is accurate and complete with no surprises, as follows:
