Drainage - Installing a Catch Basin

   A catch basin collects water from poorly drained or low-lying areas and disperses it through solid pipe. It works best in a patio or in a spot you have graded to collect runoff.
   Buy plastic catch basins at home centers. The basin is usually covered with a removable grate so you can clean it out.












Step by Step: Installing a Prefabricated Catch Basin

   1. At a low point or where water accumulates, dig a hole deep enough so that the basin's top grate will be about ╝ inch below grade.
   2. Place basin in hole.
   3. Dig a trench deep enough to accommodate a drainage pipe connecting to the basin. Using string and a line level, establish a slope of at least 1/8 inch per foot for proper drainage.
   4. Connect basin to drainpipe.
   5. Backfill trench and around basin with soil.
