A comparison of some filter materials for corrugated plastic drains
Authors: Rapp, E. And M. Riaz
Description: The problem of tiles clogging with silt and sediments has been prevalent since the installation of the first tile drains. Such deposition in the drains not only reduces the efficiency of the drainage system but also shortens its life. There fore, some protective measures must be taken to restrict the entrance of silt and sediments yet allow water to enter the drains freely. It is generally accepted that the problem of drain sedimentation and clogging can be solved by using a well designed filter. During the last decade attempts have been made to use glass fiber materials as filters for subsurface drains. There has been some research to develop design criteria for these materials to meet the requirements of an ideal filter (6, 8, 9). Some research has been conducted also to evaluate the effectiveness of various filter materials under various types of soils and placement conditions around the drain (2, 3, 5, 7). Most of the research on filter materials has been for tile drains. Only during recent years has research been carried out on cover materials for corrugated plastic drains. The main objective of this study was to evaluate the relative effectiveness of different filter materials on the flow of sediments and water into plastic drain tubes. Emphasis has been given to the filtering properties of various glass fiber materials under different placement conditions or combinations.
