We are the largest septic system design, inspection, installation and repair firm in southern and central New Jersey with over 14,000 projects completed since 1988. Our goal is to determine the least cost solution that will provide long term performance, and all work is supervised by licensed engineers. Beware of the repair by unlicensed installers - most will fail in the future and will not pass inspection when you sell your property. We offer inovative solutions that can often be accomplished without any digging or property damage. Do it right the first time with South Jersey Engineers.
