Advanced Treatment


Septic System Maintenance

Why trust your repairs or installations to anybody but the best? Excavating NJ™ will evaluate your septic system requirements, offer alternative solutions when possible, and provide complete oversight during the entire process.  Unfortunately, the septic system repair and installation profession is not licensed in New Jersey and the result is often a costly disaster. Check with us before proceeding with your project, consultations are always free.


Advance Treatment Systems provide a better and greener alternative to keeping your septic system functioning for years to come. We have designed and built a vast majority of those systems currently being used in Northern New Jersey. Due to new rules recently issued by the NJ DEP, these systems can now make your property look better, help the environment and save you money while keeping your septic system from failing and lasting many years longer.


Stop your septic system from failing before it starts, or turn back the clock for systems that are already having problems. Did you know that a new septic system can cost tens of thousands of dollars to replace?

Excavating NJ™ can provide you with services that will maintain your system and reverse existing damages for a fraction of the cost of a new system. Call Excavating NJ™ today and ask us how....
