Brief About Project

Which comes under schedule 8 (a) of listed schedules to Notification and has to obtain the Environment Clearance from SEIAA/MoEF&CC

• This is a 570 Bedded (100 Existing + 570 Proposed) General Hospital. It was established in the resettlement colony of Raghubir Nagar, West Delhi under "Special Component plan" of Delhi Govt. with a view to provide health care facilities to the low socioeconomic group of people in the area. This building is going to be developed by PWD (Health) Govt. of NCT New Delhi. • The proposed hospital project is going to offer various facilities such as: Emergency OT, Pharmacy, OBS Emergency, MRI, X- ray, Ultra Sound Diagnostics, General OTs and IPD Wards. There is counter which function round the clock in Casualty Block for registration of Admissions of Indoor Patients, which also serves as reception cum enquiry. Directions, signs /indicators at strategic points are available for the convenience of patients in all the corridors. • Considering the above, the existing land use is not expected to get altered due to construction of proposed project. Copy of land allotment letter to Directorate of Health Services from Delhi Development Authority, vide letter no JA/5844/8-85/JJ/D-19 in same context is attached as Annexure 1: Allotment Letter from DDA

• The existing buildings were constructed and also became operational prior to the publication of EIA Notification 2006. Therefore, the existing buildings did not attract applicability of to obtain Environmental Clearance from SEIAA/MoEFCC and no environmental clearance was issued to us. Accordingly, the issuance of certified monitoring report by Regional Director of MoEFCC is not applicable for the existing buildings.

Sewage Generation and Disposal During Construction Phase The quantity of sewage generation during the construction phase will be approx. 3.6 KLD.

Thus the sewage will be treated by providing small septic tanks, soak trenches and sulabh

shauchalaya type mobile toilets.

During Operational Phase Quantity of sewage generated during operational phase shall be 383KLD from Residential

and hospital building and 41 KLD from laundry. Thus the sewage will be treated through

sewage treatment plant of 440 KLD and ETP of 60 KLD capacity. The treated sewage will be

re used for flushing (132 KLD) greenbelt development (21 KLD) and for HVAC (59 KLD) .

The surplus treated wastewater during dry season (161 KLD) and during Monsoon Season

(182 KLD) will be discharge to nearby municipal sewer.

Sewage Treatment Technology Membrane Bio Reactor (MBR)


Page 15

The MBR is a suspended growth-activated sludge system that utilizes micro porous membranes for solid/liquid separation instead of secondary clarifiers. An external sewage network shall collect the sewage from all units, and flow by gravity to the proposed sewage treatment plant. Following are the benefits of providing the Sewage Treatment Plant in the present circumstances:

• Reduced net daily water requirements, source for Horticultural purposes by utilization of the treated wastewater. This shall consequently lead to a lower withdrawal from the underground aquifer water sources.

• Reduced dependence on the public utilities for water supply and sewerage systems. • Sludge generated from the Sewage Treatment Plant shall be rich in organic content

and an excellent fertilizer for horticultural purposes. The STP is being proposed with state-of-the-art membrane separation technology called as Membrane Bio-Reactor (MBR) which can produce very good quality with highest possible bacterial reduction without adding any chemicals. MBR (Membrane Bio Reactor) is the latest technology in wastewater treatment. MBR has many advantages such as higher quality of treated water, smaller space for installation and easier operation compared to conventional activated sludge process. Designed to produce high quality treated water from wastewater the Membrane Bio Reactor (MBR) is among the latest technologies in biological treatment. The characteristic of the MBR process is the use of revolutionary submerged polymeric hollow fibre membranes in the biological process water tank, so as to produce high quality permeate from domestic sewage, primary and secondary waste water, cooling tower blow down etc. The MBR is also ideal for retrofitting/augmenting capacity/quality of existing wastewater plants. The hollow fibers are combined into bundles and wound around a carrier cartridge, which gives the membranes the required strength and allows for high-pressure air scour for cleaning. The MBR can handle very high sludge concentrations in the aeration tank because of which the size of the aeration tank reduces four to five folds. As the membrane acts as a fine filter, it does not require any further treatment using sand filters, activated carbon filters, etc. The MBR is available in standard and customized modules. Process Description Figure below shows the principle of the filtration for the flat sheet type submerged membrane. Activated sludge in the aeration tank is clearly removed by the flat sheet type submerged membrane. The membrane module consists of housing, aeration diffuser; permeate water manifold and membrane elements. The membrane element consisting of flat sheet membranes sandwiching a support panel is set up vertically. Feed water including activated sludge is filtrated by flat sheet membranes with pore size of 0.1 micron meter. The air bubbles supplied from the bottom of the membrane elements continuously scour off cake of activated sludge accumulated on the membrane surface. This is continuous filtration operation. The air bubbles are also used for the biological reaction to decompose organic substances included in the raw sewage.


Page 16

MBR Module The material of the membrane is PVDF (Poly vinylidene fluoride). PVDF is fluorine polymer, which has high stability for chemicals and good physical strength. The form of membrane is fibre reinforced flat sheet membrane. The membrane has small and uniform pore size. Therefore, the rejection property of this membrane is excellent. Almost all particles with sizes more than 0.1 micron meter can be removed effectively using this membrane. Operation

Sewage from main drain line is collected through gravity pipes into a screen chamber. This manually cleaned screen is provided to remove floating and big size particles, which may choke the pumps and pipe lines. Screened sewage is then passed through equalization tank to homogenize the sewage quality and also even out flow fluctuations and feed sewage of uniform quality at constant rate to subsequent treatment units. Air mixing is also provided to mix the contents of the equalization tank. A coarse bubble aeration grid is provided to distribute air uniformly at the base of the equalization tank. After above treatment, raw sewage is fed into aeration basin. In aeration tank, MLSS (mixed liquor suspended solids) in the range of 12000 to 15000 mg/l are maintained. The high amount of bacteria gives better and complete removal of organic matter from the raw sewage in relatively small area. Oxygen required for the bacteria is supplied through the blower. The air is used both for scouring of membranes and supplying oxygen to bacteria. The filtration is carried out by the suction pump directly sucking permeates water. The permeate water produced is clear and devoid of bacteria and viruses to the minimum levels. As the membranes are continuously under operation, they are polluted with organic or inorganic substances. Hence, chemical cleaning is carried out once in two to three months for removing substances polluting and clogging the membranes. Normal cleaners used are sodium hypo chloride and citric acid.

Sewer System

Figure 3: Schematic Diagram of MBR Technology STP


Page 17

The alignment and slope of the sewer line will follow the road network, drains or natural ground surface and will be connected to the trunk sewers. The discharge point will be a treatment plant, a pumping station, a water course or an intercepting sewer. Pumping stations would be provided at places where the natural slope of the terrain is insufficient to permit gravity flow or the cost of excavation is uneconomical to do the same Wastewater details are given in Table 16 Table 16: Wastewater Details

All the joints from piping system will be checked periodically and carrying treated wastewater pipes will be laid in conduits wherever road crossings are expected. Thus no leaching of treated sewage into nearby water courses shall take place. Supervisors will be employed for overall operation & maintenance of water supply, waste water treatment and other utility services Rainwater Harvesting and Storm Water Drain A rainwater harvesting system comprises components of various stages -transporting rainwater through pipes or drains, filtration, and recharging the ground water through tanks. Percolation pits will be constructed for ground water recharge. Runoff from the first spell of rain carries a relatively large amount of pollutants from the air and catchments surface so the system will be provided with a filtration pit consisting of layers of sand, gravel and pebbles of relevant sizes to remove impurities from the collected rainwater. Need For Rainwater Harvesting Surface water is inadequate to meet the daily demand and we have to depend on ground water. • Due to rapid urbanization, infiltration of rain water into the sub-soil has decreased drastically and recharging of ground water has diminished. • Rainwater harvesting prevents the flooding of low-lying areas in the site. Rainwater Harvesting Network Rain water harvesting pits will be constructed all around the compound wall to collect rain water. Excess storm water will be allowed to drain into the external storm drain.


Page 18

Rain water harvesting has been catered to and designed as per the guideline of CGWA. Peak hourly rainfall has been considered as 45 mm/hr. The recharge well of 4 mtr dia and 2 mtr depths will be constructed for recharging the water. The bottom of the recharge structure will be kept 5 m above this level. At the bottom of the recharge pit, a filter media is provided to avoid choking of the recharge bore. The pit will be filled with rounded gravel 5 to 10 mm size. The sectional detail of the proposed rain water recharge pit is provided in Figure 4 The path ways around the harvesting lines will be graded to facilitate drainage into trenches proposed around the compound. Recharge wells/pits are envisaged along the path of the storm water drains for rain water recharging & surplus water from the recharge wells/pits shall be diverted to the storm water drainage network. The collected storm water will be allowed to percolate to the sub-soil by suitably designed percolation pits. The pits will be designed based on the soils percolation capability. The subsoil water table is high in these areas and however harvesting pits with bores will be provided. Percolation pits of suitable numbers will be provided for recharge of ground water potential. A total of 13 rain water harvesting pits will be constructed. The quantity of storm water load for the proposed construction project is given below. Calculations of run-off:

Following arrangements will be made at the site in accordance to Municipal Solid Wastes

(Management and Handling) Rules, 2016.

Bio-Medical Waste

Collection and Segregation of bio medical waste

• Collection of bio medical waste will be done as per the bio Medical waste (Management and Handling) rules 1998.

• General health-care waste will be collected the stream of domestic refuse for disposal. • Sharps will be collected together, regardless of whether or not they are contaminated.

Containers will be puncture-proof (usually made of metal or high-density plastic) and fitted with covers.

• Highly infectious waste will be, whenever possible, be sterilized immediately by autoclaving. It therefore needs to be packaged in bags that are compatible with the proposed treatment process: red bags, suitable for autoclaving, are recommended.

• Small amounts of chemical or pharmaceutical waste will be collected together with infectious waste.

• Waste will be collected and stored in colour coded bins. Treatment of Waste Treatment options for bio medical waste are Here are mainly five technology options available for the treatment of bio-medical waste. They can be grouped as follows.

• Chemical processes • Thermal processes • Mechanical processes • Irradiation processes • Biological processes

Chemical Process These processes use chemicals that act as disinfectants. Sodium hypochlorite, dissolved chlorine dioxide, per acetic acid, hydrogen peroxide, dry inorganic chemical and ozone are examples of such chemicals.


Page 24

Thermal processes These processes utilise heat to disinfect. Depending on the temperature they operate, like

• Autoclaving is a low heat thermal process and it uses steam for disinfection of waste. • Microwaving is a process which disinfects the waste by moist heat and steam

generated by microwave energy. Mechanical processes

• These processes are used to change the physical form or characteristics of the waste either to facilitate waste handling or to process the waste in conjunction with other treatment steps. The two primary mechanical processes are

• Compaction - used to reduce the volume of the waste • Shredding - used to destroy plastic and paper waste to prevent their reuse. Only the

disinfected waste can be used in a shredder. Irradiation processes In these processes, wastes are exposed to ultraviolet or ionizing radiation in an enclosed chamber. These systems require post shredding to render the waste unrecognizable. Biological processes Biological enzymes are used for treating medical waste. It is claimed that biological reactions will not only decontaminate the waste but also cause the destruction.

Domestic Waste Collection and Segregation of Waste

1. A door to door collection system will be provided for collection of domestic waste

in colored bins from residential units.

2. The local vendors will be hired to provide separate colored bins for dry

recyclables and Bio-Degradable waste.

3. For waste collection, adequate number of colored bins (Green and Blue & dark

grey bins– separate for Bio-degradable and Non Bio-degradable) are Expansion of

to be provided at the strategic locations of the area.

4. Litter bin will also be provided in open areas like parks etc.

Treatment of Waste

• Bio-Degradable wastes

Figure 6-Solid Waste Management Scheme-Hospital Waste (Operation Phase)


Page 26

1. Bio-degradable waste will be subjected to Organic Waste Converter and the

compost/resultant will be used as manure.

2. STP sludge is Expansion of to be used for horticultural purposes as manure.

3. Horticultural Waste is Expansion of to be composted and will be used for gardening purposes.

• Recyclable wastes i. Grass Recycling – The cropped grass will be spread on the green area. It will act as

manure after decomposition. ii. Recyclable wastes like paper, plastic, metals etc. will be sold off to recyclables. Disposal

Recyclable and non-recyclable wastes will be disposed through Govt. approved agency. Hence, the Municipal Solid Waste Management will be conducted as per the guidelines of Municipal Solid Wastes (Management and Handling) Rules, 2016,.A Solid waste management Scheme is depicted in the following figure.

Figure 7 : Solid Waste Management Scheme (Operation Phase)

Organic Waste Converter A waste converter is a machine used for the treatment and recycling of solid and liquid refuse

material. A converter is a self-contained system capable of performing the following

functions: pasteurization of organic waste; sterilization of pathogenic or biohazard waste;

grinding and pulverization of refuse into unrecognizable output; trash compaction;

dehydration.


Page 27

Figure 8 : Organic Waste Converter

Benefits of organic waste converter: 1. Large quantity of solid waste is converted to fertilizer in a very short period 2. Fertilizers can be sold as compost to farmers, or used for gardening 3. Machine requires less space and the efficiency is high 4. Manpower and maintenance is very less 5. This is one of the latest techniques of managing solid waste. .
