Prior to the 1960s, the majority of homes were built with a water management system that drained directly into municipal storm sewers. Unfortunately, this type of drainage system is now considered illegal in many parts of North America. In many instances, storm water collected by each home was too much for the municipality to handle, overflowing into the sanitary sewer system. Sewage treatment plants could not accommodate the amount of runoff water that flowed into the system, discharging tons of untreated sewage into lakes and streams in the area. As these lakes and streams are also sources of drinking water for the area, the situation posed a serious health threat for inhabitants.
Most downspouts attached to homes are now designed to eliminate runoff water by simply discharging it on the ground, near the base of the house, or slightly further away. Downspouts may also be attached to an underground drainage system, also known as a French Drain. However, this design is costly, requiring professional routine clearance of debris and other clogging substances in the underground piping. Both types do not discharge water directly into the municipal storm sewer; runoff water...
