Storm water Management using Bioretention Filter

Bio-retention filtration system is the leading water conservation strategy that makes use of biogeochemical techniques within a vegetation ecosystem to retain soil moisture, purify and conserve stormwater in urban cities. The present study was aimed at designing a bio-retention filter basin in the Kharghar node of Navi Mumbai, Maharashtra, India. The analysis was carried out for both minor and major floods. Total discharge was computed as 0.023 m3/s for minor flood conditions and as 0.037 m3/s for major flood conditions. The maximum infiltration rate was computed as 0.0047 m3/s considering sandy loam soil as the filter media. 100 mm PVC pipe was proposed as they are the best in terms of performance and have an advantage over other pipes. The vegetation for the bio-retention basin can be Doob or Bermuda grass (Cynodon dactylon) as it has the highest water retention capacity as per Indian soil conditions. The researchers dealing with stormwater management, water purification, waterconservation towards their academic and research pursuit, socio-economist and non-government agencies could benefit from this book.
