The design of the system depends entirely on the drainage characteristics of the soil. It is then pumped to the sand filter. 1-6 Excavation and beds and surrounds have all been removed 34. Catch basins help maintain proper drainage and catch debris, which helps prevent pipes downstream from becoming clogged. A series of pipes, commonly called a "loop," carry a fluid used to connect the geothermal system's heat pump to the earth. The pipes convey the water to a collector drain (see Fig. The main goal behind BS 8102 is to guide designers in assessing the potential risk of water ingress to a below-ground structure and identify the most appropriate and adequate ways to safeguard The purpose of the underground drain is to re-direct the water away from the home, usually to the street or the sidewalk.
