One such gutter system is called an underground catchment system. This is an alternative to draining roof runoff into daylight. This type of system works like this: the downspout can connect to a catchment system, storm sewer, or rainwater harvesting system. One type of catchment system is a drywell that can be installed underground, but many types of both underground and above-grade catchment systems are available. When designed to collect roof runoff and properly drain overflow, rainwater harvesting systems, which retain the water in a tank for use in watering landscaping, may also be used to meet roof drainage requirements.

If you think a catchment system might get the job done most effectively for you, follow these steps from the U.S. Department of Energy: Energy Efficiency and Renewable Energy from their website, Building America Solution Center. Here’s how to install a catchment system:

  1. Connect downspouts to lateral piping that extends at least 10 feet from the foundation.
  2. Provide overflow protection to alleviate the water load during peak rain events. Locate overflow pipe at a branch in the downspout, or tee-off near the top of the catchment basin. If it branches off the downspout, as shown in this illustration, it must extend at least 5 feet from the building foundation and drain to daylight.
  3. 3a. Install a clean-out in the catchment basin. In a drywell, as shown here, this clean-out consists of a perforated pipe through the center of the gravel that allows the basin to be flushed out periodically. The clean-out should also connect to the lateral pipe to allow leaves and other debris to be removed
  4. 3b. Isolate the catchment basin with a geotextile filter fabric to prevent soil intrusion from clogging the system.
  5. 3c. Fill the basin area with coarse gravel. One to 1½-inch gravel is typical. Small gravel will tend to clog too quickly (EPA 2012).
