Good drainage in the landscape is as important as proper irrigation. Too much water in landscaped areas can result in numerous plant diseases and can even kill sensitive plants like expensive evergreens. Overly wet turf areas are prone to soil compaction and scarring from footprints and mowing equipment.
Poor drainage can have disastrous results on both your yard and your home. Horticare & Associates can help. While not our main focus, drainage is always a factor when developing a landscape. Horticare installs French drains, gutter downspout drainage, swales and dry stream beds while implementing landscape projects.
The solution may be as simple as reshaping flower beds, or might include French drains, or drain lines to the street. Whatever the situation, we will work with you to find a solution that best fits your needs.
Drainage systems can use a variety of techniques to remove unwanted water from an area, whether on a residential or commercial site.
Surface Drainage Systems
Surface drainage systems aim to collect excess surface water from hardscaping, planter beds, window wells, and specific turf areas where water tends to collect. Water enters a surface drainage system through catch basins, which have a sump area that collects debris to prevent clogging of the piping.
Catch basins and the drainage grates that go on top of them are available in a variety of sizes and styles depending upon the application.
Round drainage grates are used in turf areas.
Square drainage grates are used for hardscape areas; walkways, driveways, parking lots, around swimming pools, etc.
Atrium drainage grates have a raised "domelike" design to prevent debris from building on top of the grate openings.
These are used in window wells, planter areas, and other applications where bark mulch, stone, or landscape debris would tend to cover drain openings.
The size of the catch basin should be sized to the anticipated volume of water to be collected. In addition the pipe carrying the water from the catch basin should be properly sized to carry water from all catch basins to which it is connected. Always size a little larger than necessary for safety. The additional material cost is minimal and mistakes can be costly. If the drain will be exposed to weight or traffic from above, you may need to consider a concrete catch basin and/or a metal drainage grate. The drainage line connecting the catch basins should be of a solid (non-perforated) design. Both solid PVC and corrugated plastic piping are acceptable.
Another form of the surface drainage system is the channel drain. Channel drains are frequently used in paved areas to collect water. They are essentially an extended trough or catch basin covered by a long grate.
The most frequently used form of sub-surface drainage is the French Drain or underground collection drain. This drain collects underground water from saturated soils and carries it to a desired destination. Sub-surface drains help carry water away from low spots and can protect drainage sensitive plant material.
French Drains collect sub-surface water from poorly drained areas and carry it to a main drainage line, dry well, ravine, or the street. French drains can intercept water that is draining from adjacent properties and carry it away before it enters your landscape.
