Q: What can I do to prolong the life of my septic system?

• <div>The easiest thing you can do to prolong the life of your septic system is to adopt septic-safe practices.

It&rsquo;s also important to fix plumbing leaks promptly and to practice water conservation to avoid overloading the system.

JP Sitework was $20k over the other 4 bids I received for the same project for a septic system. They offer other services such as land clearing and site preparation which would be great if the bids were not excessively higher.
