Drainage System Types
Water that remains on the surface is of no use to the grass plants that you want to keep healthy. It also prevents people from enjoying the landscape. Drainage systems are comprised of one or more components that allow surface water to recede into the ground, optimally at the same level as the roots of the grass plants. If there is a significant surplus of water, then it needs to be redirected to other areas.
Types of Drains and System Components
Slit Drains
Slit drains are narrow “slits” cut into the soil to form a series of tiny trenches over an area. The slits are quite close together, and are filled with sand or pebbles. The turf above each trench is carefully cut and rolled, and then replaced on to of the sand, making for quick aesthetic recovery.
Lateral Drains
Lateral drains are perforated pipes laid into narrow trenches. The piping helps to disperse the water between the pipes, and to surrounding areas.
Collector Drains
Collector drains are solid sub-surface pipes that quickly move water away from an area, into a collecting pool or the sewar system.
Sand Capping
Sand capping is the process of creating a layer of sand between the native soil and the sod. The thickness is variable, depending on the geography and issues being addressed. The purpose is to allow water to drain further down than the roots, so that the roots are able to also gather oxygen and don’t become infected with disease.
Sand Banding
Sand banding is similar to slit drainage, except no pipes are laid. Drainage occurs through the sand channels, which are one-half inch wide, ten inches apart, and up to ten inches deep.
Catch Basins
Trenches covered with turf, direct runoff to a catch basin that moves water through a pipe to a designated outlet. The only visible part of the system is the grate covering the catch basin.
One or several of these techniques may be recommended to solve the drainage problems you’re experiencing.
