The most effective drainage systems for soil based sports fields are what we term “Surface” drainage systems. These are a series of drain lines that come to the playing surface which are filled with a homogenous material. This material is a course grade of sand. There is no native soil placed over these lines, hence the term surface drainage. The turf grows into the sand and with good cultural practices, i.e.: aeration (both coring and slicing) and topdressing, the infiltration rate into these lines makes it possible for the field to remain firm. It should be noted at this time that if you install a drainage system and do nothing additional to the field to accentuate the effectiveness of the system — it will fail as soon as the lines seal over. However, with the systems that we install — all of the lines have locator wire buried with the drain pipe making it possible to locate these lines in case they do seal over. Simply using a lawn edger and cutting a narrow trench over the lines will re-energize the system. If you spend the money necessary to make a problem field work properly — you must be able to commit money to keep your cultural practices at a designated level.
Installing a drainage system like we are discussing is not as simple as using a recipe with the end product always predictable. For example, if the field is totally flat it is more difficult to move the surface water into the drain lines versus the water flowing off a crowned field. More than likely the flat field will have the drain lines more closely spaced than the crowned field. The equipment used to install the drainage is very fast and clean. We can help you design a drainage system that will meet your needs.
