The water is carried to the french drain in a plastic drain tile and is absorbed into the ground. The french drain must be built far enough from the house to prevent any of the water from re-entering the basement or crawl space. Back to the top Storm Sewers Where storm sewers exist, water from the gutters, downspouts, and drain systems should be diverted to this storm water system. Back to the top Storm Water Utilities It is important to check with the local engineering department or storm water utility to ascertain the rules and regulations regarding storm water systems in your area. If a storm water system exists in your area, they are likely to have a map showing where the lines run and approximately how deep they are.
Many jurisdictions require on-site systems for storm water dispersal.
To reduce the likelihood of damage and the amount of leaves and other debris which clog the gutters and downspouts, be sure that tree limbs and other vegetation are kept away from the roofs, gutters, and downspouts. An additional way to reduce the moisture in basements and crawl spaces is to ensure a good slope away from the house for all soil, patios, and walkways. It is also important to maintain a separation of a minimum of four to six inches between the top of the soil around the house and the lowest row of siding. This prevents the likelihood of water entry into the basement or crawl space, and reduces the possibility of wood rot in the siding, sheathing, and framing of the house. You are not alone with your gutter, downspout, and drainage concerns.
