Water Supply, Wastewater Generation, Recycling And Discharge Daily water demand of the proposed Hospital project during operation phase will be 482 KLD. Out of the total water demand, 465 KLD is fresh water demand and rest 17 KLD (landscaping 17 KLD) will be recycled from treated wastewater. The fresh water will be supplied by KMC. Wastewater generation from the proposed Hospital will be 332 KLD. The wastewater is being collected through a well designed sewer network leading to STP. The STP is based on MBBR technology followed by tertiary treatment.

Solid Waste and Bio Medical Waste Generation and Its Management Constructional Phase Solid Waste Solid waste during constructional phase will mainly be excavated earth, concrete debris with bits and pieces of steel, insulation materials for air-conditioning and packaging materials, cement bags, waste papers, cardboard packing materials etc. Solid wastes which are saleable and finally sold to recyclers. Rest will be disposed off in areas designated by the local authority. Operational Phase Solid Waste Approximately 622 Kgs municipal waste per day- mainly food waste i.e Biodegradable solid waste (other than Bio-medical waste) and 623 Kgs. of Nonbiodegradable solid waste (other than Bio-medical waste) per day will be generate in the Desun Hospital. Adequate number of collection bins, separately for biodegradable and non-biodegradable wastes will be provided as per Municipal Solid Waste (Management and Handling) Rule, 2016. Waste form such bins will be collected separately on daily basis. Planned and timely collection at the place of origin by housekeeping staff and closed transport to storage yard will also recommended. Collected wastes will be stored separately in a secured enclosure within the premises from where wastes will be collected by the Municipal Authority on daily basis for ultimate disposal. Non biodegradable wastes will be sold to vendors for recycling. About 177 kgs [phase-1 : 71 kg/day and Phase-2 (proposed) : 106 kg/day] of Bio-Medical wastes per day will be generated which will be collected timely in a planned manner at the place of origin as per State Pollution control norms by housekeeping staff and closed transport to closed storage yard will have done. Colour coded special closed containers will be provided as storage yard which will be removed by M/s. Medicare Environmental Management Pvt Ltd. for disposal by safe transport method. Tie up arrangement would be made with KMC for the disposal of Bio-Medical Wastes in an approved central Incinerator for Biomedical waste disposal on a routine and regular basis as per the State Pollution Control norms and regulations or the Bio-Medical Wastes would be disposed by the agency appointed by local body for BMW disposal. In general the BMW disposal will abide the regulation of Biomedical Waste (Management & Handling) Rules 1998. Agreement with M/s. Medicare Environmental Management Pvt Ltd. appointed for BMW disposal: (Annexure - 2). Liquid Waste A sewage treatment plant (STP) for whole campus based on MBBR technology followed by tertiary treatment will be set-up in the project. Hazardous Wastes Spent Oil generated from DG sets and other wastes will be sold to recyclers authorized by State Pollution Control Board. Page 4 of 7
Operational Phase Diluted Formaldehyde (1:10) will be used for OT and other sterilization. About 10 liters Formaldehyde per month will be used. Formalin will routinely used for preservation of dead bodies / cadavers in a wet bath tub type covered tanks. About 30 liters Formalin per month will be used and the spillover formaldehyde usually drained through a separate drainage pipeline to ETP and treated effluent will be disposed off in a more natural way. X- Ray developer i.e Silver Nitrate will be used. After use of Silver Nitrate it will be sold to commercial venders. Solvents like Ammonium Chloride will be used in hospital labs and in the practical labs of the students. Mercury will only used in thermometers and it may be hazardous in case of accidental poisoning or otherwise it has no role in hospital as hospital waste. Scavenging and Waste Anesthetic Gases (WAGs) system will be followed and in this system no anesthetic gases will be harming or polluting as before. Storm Water Management This is a plain developed land with no significant undulation. The total land area of the proposed project is 9197.11 sqm. By applying rational formula the peak rate of storm runoff considering 12 mm/hr rainfall is given below. Total land area = 9197.11 sqm = 0.9197 ha. By applying rational method the peak rate of runoff = 10 x 0.60 x 12 x 0.9197 cum. /hr. = 66.24 cum. /hr. = 0.0183 cum/sec. Velocity through pipe is 1.0 m/sec (non scouring and non silting). The required diameter of pipe is 160 mm. The storm drains of the Hospital Building Project is collecting and conveying the rainwater into the adjacent KMC drain. The internal drainage system has been designed considering the invert level of the KMC drain (outfall) in-front of the project site to avoid any flooding or water logging in the site. RAIN WATER HARVESTING As per MoEFCC guideline for Rain water harvesting : Roof Top Rain water storage : Atleast 1 day fresh water demand Recharge structure : 1 recharge structure for 5000 sqm built up area Proposal: Fresh water demand for the project is Total Built Up area of the project is : 465 KLD : 27379.51 sqm. We are proposing to make surface water storage to meet at least 1 (one) day fresh water demand and subsurface recharge through recharge structure of suitable diameter per 5000 sq.m built up area. We are proposing 2 no. storage tank of 235 cum capacity for roof top rainwater storage. Recharge structure of 6 nos. (27379.51 /5000 = 5.47) STORAGE TANK 2 NOS. 2 FINALLY DISCHARGED TO KMC DRAIN Page 5 of 7
Electricity, DG sets, Stack height Electricity is supplied by CESC. The connected load is about 3000 KVA (Ph 1-1000 KVA, Ph 2-2000 KVA). DG sets 2x 1500 KVA DG Set will be installed for backup power. The emission from DG sets will be discharged through 7.7 m stack for each 1500 KVA DG set above the roof of the DG building. Fuel (low sulphur diesel) required for DG sets will be about 480 litre/hr. Fire Fighting There will be all provisions as per NBC-2016 of fire fighting for the given height of the building. Clearance from WBFES will be obtained. Page 6 of 7
