LONG-TERM PERFORMANCE OF HORIZONTAL DRAINS

A history is given of the 40 years of development of horizontal drain installation techniques and equipment in California. The long-term performance of three drain installations--Cloverdale, 1941; Nojoqui Grade, 1940; and Pacific House, 1969--is evaluated. Major factors that influence the long-term performance of horizontal drains are discussed, such as location and installation methods, the frequency and quality of inspections, cleaning and maintenance programs, the types of casing used, the lithologic characteristics of the site, the pH and mineral contents of the groundwater, and the protective measures necessary to preserve external features such as outlets and collector systems.
