[ Root Intrusion ] - The Water Environment Research Federation (WERF) is funding a study of the effects of root intrusion on collection systems.  The study team includes North Carolina State University (NCSU); the Town of Cary, NC; Southern Illinois University; Duke’s Root Control, Inc., and Solutions-IES.  The study’s objective is to identify the most detrimental tree roots to centralized and decentralized systems, and determine the best control methods while considering environmental effects.

This survey asks a series of questions related to your collection system characteristics and the nature of problems associated with root intrusion.

[ Fats, Oils, and Grease ] - The Water Environment Research Federation (WERF) is funding a study of the effects of fats, oil, and grease (FOG) on collection systems.  The study team includes North Carolina State University (NCSU); the Town of Cary, NC; Southern Illinois University; and Solutions-IES.  The study’s objectives are to:

• determine the optimum design, operation and maintenance for grease interceptors
• evaluate the effects of combined commercial, domestic, garbage grinder waste on grease interceptors
• determine if different piping materials have different susceptibility to blockages caused by FOG

This survey asks a series of questions related to your collection system characteristics and the nature of problems associated with FOG.
