Culverts and Drainage

Course Description:

This workshop includes the basics of drainage and selecting, sizing, and installing culverts. Items covered will include drainage law in Kansas as it relates to backwater and changing the natural drainage pattern, factors that affect the amount of runoff and the sizing of culverts, and using common sense in culvert sizing.

Information will be provided on the types of culvert products available, including the pros and cons of the various products, and proper installation techniques. Common causes of culvert failures will be discussed as well as culvert rehabilitation and lining. Work around streams is regulated by environmental agencies so environmental issues and permitting will also be discussed.

This workshop is designed for maintenance crews, foremen, and supervisors who provide and maintain smaller drainage facilities along rural roads and city streets. This includes county and city engineers and road supervisors, technicians and road crew members, township trustees, and State staff who have drainage responsibilities. Elected officials are also welcome to attend.
