The Sulejów Reservoir  is a shallow and eutrophic, situated in the Central Poland, in the middle course of the Pilica River. At its full capacity this reservoir covers the area of 22 km², mean depth of 3.3 m and volume of 75 x 106 m³. The reservoir is an important dam reservoir for flood control and power generation, but also important site for fishing and recreation. Until 2004, it had supplied the drinking water for the City of Lodz. It has been studied extensively for the presence of toxic cyanobacteria. Microcystis aeruginosa is the dominant species of bloom-forming cyanobacteria, which produces microcystins.

As an example of the NBS application, highly effective buffer zones were designed and implemented in the direct catchment of the Sulejów Reservoir, an area characterized by heavy pollution of its groundwater. Barkowice demosite of LIFE+EKOROB project is surrounded by agricultural land  Nitrate concentrations (~ 100 mg NO3/l) in groundwater classified it as polluted, according to the Nitrates Directive (>50 mg NO3/l). The solution tested in the area was a denitrification wall as an additional element in the plant  buffer zone. Although it is an artificial structure, such a wall is invisible in the landscape and intensifies the naturally occurring process of denitrification - a key microbial nitrogen phase circulating in the biosphere.

Reservoirs in Arturowek (Łódź city) represent one of the key recreational areas for Lodz residents. Similarly to a majority of waterbodies in urban areas, they are severely impacted by anthropopressure, which affects their water quality, and as a result limits their functionality. Attempts to improve this condition were made in the past, however they did not result in permanent improvement of the situation. Therefore it was necessary to reduce the inflow of pollution which affected the reservoirs’ recreational function. 

An attempt to implement comprehensive rehabilitation-focused solutions in order to improve the quality of the Bzura River and eliminate cyanobacteria which form in the reservoirs was made under a European Project LIFE+: ‘Ecohydrologic rehabilitation of recreational reservoirs Arturówek (Łódź) as a model approach to rehabilitation of urban reservoirs (EH-REK)’ (LIFE08 ENV/PL/000517).

The integration of hydrological and biological methods can effectively limit the inflow of pollutants to water reservoirs and reduce the problem of the toxic cyanobacterial blooms in reservoirs. An example of such a combination is the sequential sedimentation-biofiltration systems (SSBS) constructed in Upper Arturówek reservoir. The effectiveness of such a system in the removal of pollutants was estimated for total suspended solids supplied to the reservoir by river by 90% and aprox. 60% reduction of the total nitrogen and phosphorus. Such systems can be additionally equipped with underground separators and sedimentation tanks responsible for the pretreatment of stormwaters with the sediments discharged from streets and parking places (e.g. oils or fuels from motor vehicles). Such enriched systems called hybrid systems, are characterised by a higher efficiency in removing suspended matter (up to 98.6%) and nutrients from 40% to 97.5%. 

An example of such a system was implemented below Wycieczkowa street in Łódź for the retention and treatment of the rainwater previously discharged from the street, pavement and parking places directly into the river.
