2. To help develop and improve on-site technologies that will allow people to use their land in an economically affordable way that protects their communities health and investment as well as the environment.
3. To provide research based training and educational opportunities regarding on-site septic systems for county agents, state and local regulatory officials, private consultants, installers, operators, realtors, and the general public.
2. To assess the performance of sand lined trench systems on wet, clayey soils of the lower coastal plain in northeaster North Carolina.
3. To develop a critical mass of professionally trained on-site system operators who can keep alternative types of septic systems operating properly for the long term.
2. The North Carolina Subsurface System Operators Training School was established in 1992 and over the past three years about individuals have participated in this training and passed a state certification exam to become Certified Subsurface System Operators.
3. The NCSU On-Site Wastewater Management Training Facility was established in 1989 at the Walter Bright Farm in Chatham County to provide hands-on learning opportunities. This Field Training Facility is now being duplicated at educational institutions across the country due to efforts of the newly formed Consortium of Institutes for Decentralized Wastewater Treatment.
4. An in depth assessment of sand lined trench (SLT) septic systems on wet clayey soils indicated that when these systems are used in conjunction with- well maintained drainage systems, they performed comparable to conventional septic systems used on well-drained, loamy soils.
2. Assessment of the effect of depth and duration of saturation on wastewater treatment in wet soils.
3. Evaluation of methods to improve the siting and long-term operation of large on-site systems serving subdivisions schools and small communities.
