The property serves as a storage and maintenance area for leasing client’s operations. Irrigation for the site is intended to provide supplemental water for the new landscape plantings and serve as a stormwater management tool. All stormwater collected on site is directed to and stored in a lined pond. LIS was hired by Stormwater Solutions Inc. to satisfy the irrigation design requirements.
Natural site conditions, high water table, clay soils, and a flat site, prohibit soil infiltration as a stormwater management method. In addition, municipal stormwater management restrictions dictated the use of a new and promising stormwater management method called ‘Enhanced Evaporation’. ‘Enhanced evaporation’ involves delivery of the excess stormwater onto adjacent site surfaces such as rooftops and hard surfaces (i.e. parking tarmac) where it is allowed to evaporate.
Essentially, LIS designed two specific irrigation systems for the site. The first, a conventional irrigation system utilizing highly efficient sprinklers and irrigation runtimes to deliver only the water required by the landscape. The landscape water requirements are monitored by soil moisture sensors which provide soil moisture condition feedback to the irrigation controller.
The second irrigation system intended for ‘enhanced evaporation’ only, delivers stormwater via landscape drip lines to the perimeter of the extensive recycled asphalt tarmac where it is allowed to evaporate. ‘Enhanced Evaporation’ operation runtimes are scheduled into the irrigation controller and monitored by pond level sensors to ensure pond levels are maintained within specific tolerances.
