File No.EIC II-221001/3/2019-O/o (SE)Sewerage System(OandM) 819 I/3208/2021 REPORT ON ABETMENT MEASURES UNDERTAKEN BY GMDA TO NEGATE THE ADVERSE IMPACT OF CONCRETIZATION OF BADSHAHPUR DRAIN BACKGROUND Grievance had been brought to the notice of Hon’ble NGT vide O.A. 523 of 2019 Vaishali Rana vs UOI w.r.t. concretization and boxing of the KOSHT- Badshahpur Drain in District Gurgaon affecting rain water harvesting and alleged obstructing the natural flow of water. Honble NGT vide order dated 31.5.2019 sought a report from HSPCB about the impact of the concretization and boxing on groundwater recharge, e- flow of water in the drain and impact on urban sprawl. HSPCB vide report filed on 21.10.2019 submitted that concretization reduces the ground water recharge. Hon’ble NGT directed that the fact remains that even if the concretization is not to be undone, the abatement measures need to be adopted to ensure that rain water harvesting and ground water recharge are not affected and flooding is avoided. GMDA apprised the Hon’ble NGT regarding the abetment measures being considered to negate the adverse impact of concretization of badshahpur drain. Vide order at 07.09.2020, Hon’ble NGT has asked to explain how the increased flooding potential and reduced recharge would be neutralised by the project. Accordingly, Sh. A K Bhatia, Retired Regional Director, CGWB who is an expert in the field of groundwater recharge, had been requested to submit a report in this regard. Report of the expert be referred at Annexure- R/1 and summarised as under: A. ADVERSE IMPACT OF CONCRETISATION OF DRAIN Existing Badshahpur drain was concretised 5 yrs ago by HSVP. The detail of the concretization of Badsahahpur drain chainage wise from Vatika Chowk near Village Badshahpur up to Railway line are as under: Sr Node Length of Size of Concrete drain Remarks No drain in Mtr construction in Mtr 1 A to B 2100 1x6x1.82 New drain constructed and 2 B to C 4950 3300 mtr- 1x6.6x1.82 part of the natural drainage 1650 mtr- 1X7X1.82 diverted. 3 C to D 2760 1x7x1.82 Natural drain converted into box drain 4 D to E 1550 1x7x2.4 Natural drain converted into 1x3x2.1 box drain 3 E to E’ 910 1x8x2.4 Natural drain converted into 1x5.5x2.1 box drain 5 E’ to F 600 2x5.5x2.4 Natural drain converted into 1x4x2.4 box drain 6 F to F1 Village Area Existing Pipe drain File No.EIC II-221001/3/2019-O/o (SE)Sewerage System(OandM) 820 I/3208/2021 converted in to box drain. No Change in Characteristics of the drain 7 F1 to G1 600 3x4x2.75 Natural drain converted into 1x4x2.4 box drain 8 G1 to H 1410 3x4x2.75 Natural drain converted into 1x4x2.4 box drain 9 H to I 1840 3x4.5x2.75 Natural drain converted into box drain 10 I to J 2500 Open katcha drain at Open drain to be present. channelized with Katcha bottom and the seepage into the ground will remain as such 11 J to K 2900 3x6.7x2.4 Natural drain converted into box drain 12 K to L 3270 Open katcha drain at Open drain to be present. channelized with Katcha bottom and the seepage into the ground will remain as such Total 25390 19620 length drain Length constructed and 5770 mtr length not concretized The total length of drain concretized and converted in to a box drain 19620 Mtr. There existed pipe drains in village area between nodes F to F1 and has been converted in to a box drain to increase the capacity but there is no change in the nature, as earlier it was a pipe drain and now it’s is box drain. The node I to J the drain has not yet been concretized and it is proposed to retain a open drain with Katcha bottom as such no change in the character of drain is under consideration. The seepage norms for natural drain are similar to the seepage from the unlined canals. As per the rainfall data summary given below, total rainfall hours in a year 43.5 hrs. It has been assumed that based on the feeding channels/ drains to the main drain, it will take about 2 hrs to reach the major Badshahpur drain i.e. if the rain is for 1 hour, the drain would run for 3 hours. The total seepage prevented by the above process has been calculated and enclosed in Annexure-A. Reduction in the recharge because of concretization of drain (Badshahpur drain)= 3,62,835 Cums. ---------------(X) File No.EIC II-221001/3/2019-O/o (SE)Sewerage System(OandM) 821 I/3208/2021 B. ABETMENT MEASURES TO NEGATE THE ADVERSE IMPACT OF CONCRETIZATION OF BADSHAHPUR DRAIN Comprehensive drainage plan of the part area of Gurugram. A comprehensive drainage plan got prepared by GMDA for creation new pondage areas by constructing check dams across creeks, Channelization of creeks, creation of recharge wells and construction of new drain from Vatika Chowk along SPR up to NH-48 to cater the additional runoff that is generated because of increase in the urbanization in the development plan area 2031. The map of drainage system be referred at Annexure-R/2. The proposed new drainage scheme has been conceptualise to reduce the runoff, as calculated on basis of rational method as specified in the sewerage drainage manual published by Central Public Health and Environmental Engineering Organisation, Ministry of Urban Developed, New Delhi. The reduction in the runoff was required in light of the fact that all the existing bunds i.e. Chakarpur, Wazirabad etc have become redundant because of the urbanization of the areas and as such new pondage areas are required to be created to reduce the runoff and increase the pondage area and as such increase the seepage in to the ground. The new comprehensive drainage scheme has already been approved consisting of following 3 sub-heads Sr No Project Name A Channelising the creeks and creation of check dam in Non- urbanizable area in Gurugram(North-Eastern-Side) B Improvement of Drainage system from, Golf Course Extension road to Sohna road & NH-48 C Improvement of Drainage system by Construction of recharge well from Golf Course Road extension to Railway Culvert no 61. A. CHANNELISING THE CREEKS AND CREATION OF CHECK DAM IN NON- URBANIZABLE AREA The scheme is conceptualised mainly to create check dams in the non- urbanizable zone and arrest the flow of water towards Golf Course Road and provide recharge wells to recharge the Ground Water through natural and Artificial recharging of the ground, rather then constructing large drainage channels and allowing the runoff to flow ultimately in to Najafgarh drain and Yamuna River during rains. File No.EIC II-221001/3/2019-O/o (SE)Sewerage System(OandM) 822 I/3208/2021 The non-urbanizable area covered in this part of the scheme is 951 Acres and 8 no ponds are proposed to be created. To cater to the heavy and above average rainfall, 4 no. existing natural creeks are proposed to be revived as open channels with dry stone pitching in the bed that allows the Natural seepage into the ground. These creeks pass through the urbanizable area and cross the Golf Course Road. Calculation of recharge due to additional pondage areas created with check dams in non-urbanization area is as under: Pondage Avg Depth of Pondage area Volm. in cum Water in in sqm Pondage area Creek No 1 1 15943 1.98 8052 2 22978 1.75 13130 3 15415 2.28 6760 4 41418 1.55 61197 5 67517 1.68 40188 Creek no 2 1 36181 2.88 15868 Creek no 3 1 35288 1.20 29407 Creek no 4 1 40621 2.24 18134 Total 275361 192736 Therefore, net recharge from pondage of creek 1-4 will be 495650 cum per year as per details in Annexure-A -----------------(B 1) B.
