Individual Systems (“Perc” tests)

constant-head permeameterThere are probably as many different types of septic systems in North Carolina as there are counties. Every year, new systems get approved for use while existing ones often improve upon the benefits they provide a homeowner. The Catena Group stays abreast of all new developments so they can provide the individual homeowner with the most efficient and economical system to suit their needs. Whether it involves a conventional gravity-fed system, pre-treatment, LPP, or monitoring and modeling, The Catena Group has the experience and knowledge to obtain the Improvement Permit for your septic system.

The Catena Group understands that for developers, the profit is often realized in the last couple homes in a subdivision. As such, proper soil planning is imperative to maximize the efficiency of the development. The Catena Group is well experienced in providing soil and septic information that ensures developments are designed and structured correctly the first time, reducing costly re-designs and delays. We have worked in all areas of North Carolina and understand the limitations and concerns of the soils in each region. We have developed an excellent working relationship with Health Departments across the state.
