One solution for discharging the water from a drain is the installation of a drainage ditch. This may require resloping or changing the grade of the property. Houses built on slopes and hills are prone to drainage problems as water naturally drains through the yards. If your home is in the path of storm runoff, you may want to consider installing a retaining wall to reroute excess water away from your yard.

Puddling and pooling water in a yard can kill grass and other vegetation. A shallow exterior drain can direct the water to a designated holding spot, sometimes called a vertical French drain. A vertical drain can be as simple as a catch basin filled with rocks or gravel that holds excess water, or it can be more elaborate and feature buried tanks that collect the water and then allow it to drain off slowly.

A sump pump may be required for an interior or an exterior French drain if the water cannot naturally drain away via gravity. French drains are suitable for both interior and exterior use, and the price will vary depending on which one is necessary to correct the drainage problem.

While there are numerous ways to prevent a soggy yard and reroute water, installing a French drain is among the more common options.

Unless a rain garden is already established in a yard and filled with various water-loving plants, most homeowners are not fond of excess water pooling on the lawn. When grass and most plants are underwater for more than a few hours, it can increase the risk of root rot and fungal disease. A retaining wall can protect a house and yard from natural runoff if the home sits on a hill or slope, but the retaining wall itself can be impacted by lateral pressure from the water that builds up on the back side.

In time, this pressure can damage the retaining wall, so some contractors may recommend installing a French drain along the rear of the retaining wall to ease some of the water pressure. The most common reason for installing an interior French drain is flooding in the basement. While strict building codes require drainage provisions for newly constructed homes, houses were often built with substandard or nonexistent drainage systems before communities adopted those codes.
