conducted. With increase in aggregate size, the drainage slab has shown higher infiltration rate and less clogging potential. Biswajit Mukhopadhyay (2020) discussed various design methodologies and standards from different countries. The paper addressed the need for proper drainage placement to minimize erosion and structural damage and urbanization affecting drainage efficiency. Habibunnisa Syed (2020) conducted a study by incorporating coconut coir fibre in concrete. The tests are done for 0 to 1.2 percentage of coconut fibre with varying water cement ratios It has been determined that adding 0.6% and 1.2% of coconut coir fibres has enhanced the compressive strength and flexure strength, respectively. Jean et al. (2020) has conducted a study which describes how urban stormwater management has evolved historically since the mid-19th century, when modern sewer systems were introduced. It emphasizes how stormwater was first considered an annoyance and was mostly controlled via effective conveyance to water bodies. With the goal of creating sustainable and livable urban settings, this progression shows a shift from a strictly defined engineering focus to a more integrated approach that incorporates contributions from several disciplines and stakeholders. Mohamed Ahmad et.al. (2019) have designed a drainage cover slab with Eco friendly pervious concrete in which recycled materials like fly ash, wood waste ash, egg shells. Reduction in flash flood has been achieved. Paul et.al. (2019) has discussed the engineering properties of pervious concrete. Mix proportioning of pervious concrete. Design and construction of subgrade and subsoil were discussed. 80 to 90 percent of the permeability of a blocked pervious concrete pavement has been recovered by pressure washing it. Wakjira takala Dibaba (2018) focused on Jimma City in Ethiopia and identified issues such as drainage blockages, poor infrastructure, and the lack of integration with road systems as major contributors to flooding and environmental degradation. Milena et al. (2018) has studied the potential sites for bioswale implementation in Niš, emphasizing the necessity of comprehensive evaluations to maximize their size and design as well as more research in residential and multifamily housing areas. The results highlight how crucial it is to include bioswales in planning procedures because they are economical, environmentally friendly, and promote long-term sustainability in urban environments. Uvini et al. (2017) compared Sustainable urban drainage systems with conventional systems, highlighting benefits in reducing flood risks, improving water quality, and creating aesthetically pleasing and biodiversity-rich environments. Challenges include the high cost of implementation and maintenance. Lund et al. (2017) has carried out a mix design for pervious concrete in Pearl chain bridges. Permeability test, compressive strength test, shear strength and freeze thaw test were conducted. Addition of super plasticizer increased the compressive strength by 36% and tensile strength by 27%. The permeability coefficient was found to be 0.6-1.02cm/s. Seneviratne et.al. (2017) investigated the effects of coir fibre on the strength parameter of the concrete. According to the results, as fibre content and length increase, there is a noticeable decrease in compressive strength (20% to 75%) and unit weight (3% to 8%). 2% coir fibre did, however, result in a modest increase in flexural strength (between 3% and 6%). In this study, Tiza et.al. (2016) have discussed various consequences of poor drainage systems. Poor drainage has led to road surface deterioration, increased maintenance needs, and structural failures. Repair costs were increased due to an inadequate drainage system. Kevern et al. (2015) have examined cylindrical samples with different porosities and diameters. The permeability of the specimen varied significantly, with 100 mm specimens showing less variation compared to the 75 mm specimens. Marchioni et al. (2014) have highlighted the potential of permeable pavements as a sustainable solution for urban water management, emphasizing the need for continued research and development to address practical challenges. Environmental benefits, design considerations and challenges were listed. Qianqian Zhou (2014) has discussed the need for integrated, transdisciplinary approaches, including decision-aid tools and models, to support the assessment and implementation of environmentally friendly drainage systems. Sustainable drainage systems, such as permeable pavements, swales, and detention basins, are presented as a more flexible and environmentally friendly alternative to traditional systems. Salain et.al. (2014) have conducted an experimental study which showed the addition of coconut fibre to concrete enhanced its mechanical properties, with optimal fibre content improving strength parameters up to 50%. The fibres act as micro-reinforcements, reducing brittleness and increasing the load-bearing capacity, particularly in flexural strength concrete. Kshitijanad gouda (2014) found that coconut fibres reduce the weight of concrete and can be used as lightweight structural concrete while also decreasing environmental waste. Optimal flexural strength is achieved with a 3% fibre mix, but higher fibre contents (5% and 7%) do not yield better results. Uma Maguesvari (2013) has discussed the impact of angularity of fine and coarse aggregates on the characteristics of pervious concrete and the effectiveness of pervious concrete as a pavement material. The study revealed that the Permeability increased to 1.26 cm/sec from 0.4 cm/sec.
