New Bioretention Drainage Channel as One of the Low-Impact Development Solutions: A Case Study from Poland

Abstract

In recent years, as a result of intensive urbanisation, a significant increase in the surface of impermeable areas has been observed, which results in changes in the hydrological cycle of catchments. In order to counteract these changes, low-impact development (LID) solutions are increasingly being implemented in urban catchments, including bioretention systems. Taking this into account, a new bioretention drainage channel (BRC) was designed, whose main task is retention, infiltration, and pre-treatment of rainwater. The pilot laboratory tests carried out on two BRC prototypes (K1 and K2) showed that the average rate of reduction of mineral-suspended solids from rainwater was 69% and 57%, respectively, for K1 and K2. Analysing the results of the research, it was found that the bioretention drainage channel is characterised by very high efficiency in removing petroleum hydrocarbons from rainwater, and the reduction rate of these pollutants for both the K1 and K2 channels was close to 100%. In turn, hydrodynamic studies carried out on the model of the urban catchment showed that the implementation of BRCs will reduce the peak runoff by more than 82%, and the maximum flow in the sewage network by 83%.

Behaviour and Peculiarities of Oil Hydrocarbon Removal from Rain Garden Structures

“…By analysing the results of the research, it was found that the pilot structures are characterised by a very high efficiency of PH removal from rainwater, close to 100%. Similar laboratory tests were conducted on two prototype rain gardens in Poland [74]. The results showed that the bioretention structure is characterised by a high efficiency of removal of PHs from rainwater, and the efficiency of the reduction in these pollutants for both prototypes is close to 100%.…”

Evaluation of the Suitability of Using Artificial Neural Networks in Assessing the Effectiveness of Greywater Heat Exchangers

“…This approach also reduces the carbon footprint and, consequently, the environmental impact, enabling a more sustainable and informed use of resources. These savings are important given that reducing resource consumption at each stage of the life cycle of a device or process contributes to an overall improvement in its environmental sustainability [18,49]. Therefore, intelligent data selection and optimization of research processes are of fundamental importance for sustainable development and science, and the promotion of good practices and ecological solutions in engineering and technology.…”

Active Green Constructions and Their Impact on Gray Infrastructure

“…The impact of implementing green roofs on a building can be estimated, particularly in terms of rainwater accumulation. For comparative purposes, the runoff coefficient for green roofs was evaluated in accordance with several standards: the German standard (DIN 1986-100:2016-12 2016) [23], the Austrian standard (ÖNORM B 2501 2016) [24], the Slovak standard (STN 73 6760 2009) [25], and the FLL directive (FLL 2008) [26][27][28][29][30]. Tables 1 and 2 present the runoff coefficients as per these various standards (DIN 1986-100:2016-12 2016; ÖNORM B 2501 2016; STN 73 6760 2009; FLL 2008), contingent on the thickness of the substrate.…”
