Definitions

  • the present invention generally relates to a system and a method for monitoring an environmental condition in a storm drain using sensors located within the storm drain.
  • the invention also relates to a use of the system.
  • Storm water which also is called urban runoff, is surface runoff of rainwater, melted snow or ice, wash water or similar from different types of surfaces. Such surfaces may be parking lots, sidewalks, roofs, and similar surfaces, sometimes referred to as impervious surfaces. Water running off from such surfaces tends to become polluted by e.g. gasoline, oil, heavy metals, trash, fertilizers, pesticides and other pollutants. During rain and periods of snow melting, these surfaces carry polluted storm water to storm drains. Storm drains are generally connected to a drainage system for discharge into receiving surface waters, such as a canal, a river, a lake, a reservoir, the sea, an ocean, or other surface waters, with or without treatment of the storm water before discharge.
  • surface waters such as a canal, a river, a lake, a reservoir
  • Storm drains generally comprise a vertical pipe having an inlet, such as a horizontal grated inlet or a side inlet, being connected to a drainage system.
  • Such storm drains may comprise a catch basin, also called sump or gully-pot, for catching small objects, such as sediment, sand, gravel, pebbles, twigs, trash and similar.
  • the catch basin serves as a water-filled trap for trapping objects and prevent such objects from entering the subsequent drainage system.
  • catch basins also prevent gases from the drainage system from escaping.
  • storm water from the top of the catch basin drains into the subsequent drainage system.
  • the storm water may be filtered when entering the storm drain or when resident within the storm drain, in order to reduce the amount of pollutants in the storm water.
  • Another strategy is to lead the storm water to a purifying plant where the storm water is purified generally using different mechanical and chemical purifying steps.
  • Yet another strategy is to filter the storm water in the storm drain and subsequently lead the storm water to a purifying plant for a second subsequent cleaning.
  • a sudden discharge of a pollutant into the storm drain may damage the filter device resident within the storm drain.
  • a purifying plant connected to the storm drain concerned may become damaged if subjected to a sudden and/or considerable discharge of a pollutant.
  • any sudden discharge of a pollutant into the storm drain may result in that the capacity of the filter resident in the storm drain is insufficient, thus allowing polluted storm water to leave the storm drain unfiltered or at least unsatisfactory filtered.
  • Another problem is that, as the filter resident in the storm drain becomes saturated with pollutants, other objects or substances present in the storm water, the efficiency of the filter becomes reduced. As the filter becomes saturated the percolation capacity of the filter may also become reduced. As the percolation capacity of the filter is decreasing, the function of the storm drain may be affected, as the storm drain might no longer be able to receive the required amount of storm water per unit time, due to the reduced percolation capacity of the filter. This condition of insufficient percolation capacity may lead to flooding or undesired discharge of pollutions as the storm drain is no longer capable of receiving a required amount of storm water.
  • storm drains may become blocked or clogged leading to that no or just little storm water may enter the storm drain. Under such conditions, the storm drain is in principle out of operation as its ability of receiving storm water is significantly reduced or virtually non- existent. Also a blocked or clogged storm drain may lead to flooding or undesired discharge of pollutions.
  • storm drains and filters resident in storm drains are generally checked and emptied of foreign objects and substances at a regular basis.
  • the storm drain may be checked and its catch basin emptied once a year by means of a vacuum truck.
  • This procedure do however only make sure that the storm drain or the filter is operating correctly, e.g. not being clogged, blocked or damaged, once a year. This means in practice that in the most extreme case it may take up to one year to detect that the storm drain or the filer is malfunctioning.
