4. Treatment Technology Waste water, upto 3958 cmd will be generated. Recycled water (3766 cmd) will be reused for flushing, gardening and HVAC cooling. The entire quantity of recycled water will be reused on site and there will be zero discharge outside the site. Dual plumbing system will be introduced for fresh and treated waste water supply. In order to meet the stipulated standards for wastewater disposal, a Sewage Treatment Plant (STP) of Moving Bed Bio Reactor (MBBR) technology is proposed for treatment of Prepared by: Aditya Environmental Services Pvt. Ltd. 47

Proposed expansion of “Gigaplex- IT Park” at MIDC Knowledge Park, Airoli, Navi Mumbai wastewater. One STP is proposed for each building. 3958 cmd of waste water generated will be treated in proposed 11 STPs of total 4185 cmd capacity. STP process description The scheme proposed for the treatment of sewage in the proposed development is compact and effective Sewage Treatment Plants (STP) using revolutionary ‘Moving Bed Bio Reactor’ (MBBR) Technology.

Figure: Schematic of MBBR Process The concept underlining the Moving Bed bioreactor is to provide continuously operating bio- film reactor, which is non-cloggable, does not require backwashing and has a very low pressure drop. This is achieved by growing the bio-film on smaller carrier elements that move along with the waste water in the reactor. The air stream constantly keeps the bio media is in suspension and at the same time provides the required oxygen to the biomass. The system uses specially designed bio-media, which provides a large surface area for biological growth. The bio-media is made of plastic material, which has a very long life. The media is cylindrical in shape and provides a large surface area in the given volume. The media provides about 800sq.m. effective area for growth of the bio film per m3 of volume. The proposed system will consist of the following major stages: 1. Sewage Collection & Pumping System 2. Manual Bar Screen & Grit Chamber 3. Aeration Tank & Tube-deck Settlers Prepared by: Aditya Environmental Services Pvt. Ltd. 48

Proposed expansion of “Gigaplex- IT Park” at MIDC Knowledge Park, Airoli, Navi Mumbai

4. Filtration System 5. Disinfection System 1. Sewage collection & pumping system: Raw sewage will enter the raw sewage sump. Raw sewage transfer pumps will pump the sewage to the STP through the screen & grit removing stages. One pump will be on duty and the other stand by. 2. Manual Bar Screen & Grit Chamber: A combination of coarse & fine screens will be provided for removal of floating debris from the sewage. The coarse screen will have spacing of 10 mm & will be periodically cleaned. The fine screen will have a spacing of 5 mm and will be periodically cleaned. The outlet from the screen chamber is let into the sewage treatment system. 3. Sewage Treatment System: The description of the major components of the proposed sewage treatment system is as follows: A) MBBR Bioreactors The MBBR aeration tanks are located next to each other. Each of the tanks will be provided with aeration pipelines at the bottom, which will be in stainless steel & are manifold to cover half the periphery of the tank. Aeration tank is filled with a specific quantity of the bio-media, which is made of plastic material with a specific gravity just below that of water, to enable it to remain in suspension. The inlet of the aeration tank is on the top with the sewage falling freely into the MBBR tank. The outlet is located on the opposite side, which has a perforated screen mounted on it, which prevents the bio-media from flowing out of the MBBR tank. Both compartments are connected to each other by a fabricated channel, which has perforated sheets on each side. The outlet of the second MBBR is connected to the tube settler unit. B) Tube Settler Unit Sewage from aeration tank along with biological stabilized solids will flow by gravity to the compact tube settler unit. The separation of the solid from the sewage is achieved by laminar flow developed by the tubes. Due to this, heavier solids slide down along the inside of the tubes, whereas the clear water rises up and flows out.

Prepared by: Aditya Environmental Services Pvt. Ltd. 49

Proposed expansion of “Gigaplex- IT Park” at MIDC Knowledge Park, Airoli, Navi Mumbai

The sludge settling at the bottom of the tanks will be transferred from time to time to the sludge holding tank. The clear water from the settling tank will overflow into the filter feed tank.

C) Aeration System The aeration system consists of two air blowers. One blower will be on duty while the other will be on stand-by. The blowers will be used for aeration inside the MBBR. Filtration System This consists of a pressure multimedia filter that removes any remaining suspended solids in the treated water so as to ensure its total conformance with the discharge standards set by the regulatory authorities. The filter is to be backwashed at pre-set intervals with water from the treated water tank. 4. Disinfection System The disinfection system, which comprises of a dosing system, ensures complete removal of any remaining harmful organisms in the water. The water flowing into the polishing filter feed tank is dosed with an oxidant above & then allowed to remain in the tank for a predetermined time so that there is enough contact time for the oxidant to totally disinfect the water. Sludge from secondary clarifier is proposed to be stabilized by aerobic digester. In order to achieve quicker and efficient processing, filter press/ centrifuge will be installed for the process. After dewatering, the liquid will again be sent to the STP collection tank. The dry and porous sludge is proposed to be used as manure for landscaping The characteristics of sewage treated in the STP are given in table below: Table 3.3 : Sewage Characteristics at Inlet and Outlet of STP

1. OBJECTIVE The objective of Environmental Management Plan (EMP) is to formulate measures which will: 1. Mitigate adverse impacts on various environmental components. 2. Protect environmental resources wherever possible. 3. Enhance the value of environmental components wherever possible. EMP also includes a monitoring plan to enable evaluation of the success or failure of environmental management measures, and to carry out reorientation of the plan if found necessary. It is emphasized that many of the protective and enhancement measures can be implemented by adopting suitable planning and design criteria for construction of the project. The following measures have been suggested after discussion with the project proponent.

2. LAND ENVIRONMENT

2.1. Traffic Management Construction Phase There is no major impact on the land environment during construction phase as identified during studies. The internal roads will be designed with adequate width to minimize traffic congestion inside the plot which may arise due to the movement of trucks carrying raw materials required for construction. The material will be sourced from the nearest available government approved contractor. Since the road transport is unavoidable, such movement will be during non- peak hours as far as possible. Operation Phase The impact on land environment during operation phase will be due to movement of vehicles of the employees, staff and other visitors to the site. Precautions that will be taken to minimize impacts on land environment will be as follows:

° Development will be as per the DCR for the MIDC region. ° Suitable traffic management plan to be proposed.

2.2. Solid Waste Management Please refer Annexure-IV for details on solid waste management.

5.1. Construction Phase 1. Construction area will be isolated and care will be taken to divert the run-off to existing nallahs, so possibility of pollution from construction run-off is prevented. Also, subsurface work will be carried out only during non-monsoon period. 2. A storm water management plan will be implemented which will have limited impervious layer and will promote infiltration as far as possible. 3. Precaution will be taken to ascertain that no waste material like cement, paint and solid material like iron rods and any other material is dumped into existing nallahs. 4. No accumulation of stagnant water will be allowed within the project site area as well as in the vicinity to prevent breeding of mosquitoes.

5.2. Operation Phase 1. A well engineered storm water drainage system will be provided as a part of this development. Storm water will be either collected in underground tank or discharged to re-charge pits to augment the ground water. 2. Regular monitoring of proposed sedimentation trench will be carried out to prevent soil from entering existing nallahs. 3. A well designed rain water harvesting system will be implemented as a part of the project. The harvested water will be utilized for ground water recharge. Thus, there will be beneficial impact on the ground water table. 4. There will be no negative impact on ground water regime due to proposed project in the operation phase. 5. Regular monitoring will be made to avoid blocking of culverts.

6. GUIDELINES FOR BIO-AESTHETIC MANAGEMENT

6.1. Protection of trees on site Protection of existing trees within the plot which would not be affected by the proposed layout should be first priority during construction. The precautions to be taken are as under: 1. Precaution would be taken while transporting construction material to the site to prevent accidental damage or spillage. 2. The work force will be briefed about importance of preserving and protection of exiting trees before starting the construction work. 3. Trees propagation/ plantation should be initiated by project proponent from project initiation stage for better results. Prepared by: Aditya Environmental Services Pvt. Ltd. 59

4. The proposed tree species will be the fruit bearing type and native species suiting the local climate as far as possible.

6.2. Species Recommended for Plantation The basic thrust for plantation will be on ecological value followed by aesthetic value of the tree. It is recommended that tall trees should be planted to form an avenue along roads and to buffer the vehicular noise and dense canopy trees should be planted on the periphery of the plot to form a screen to reduce impact of air/ noise pollution. Following is a list of recommended tree species: 1 Neem (Azadirachta indica) 2 Rain Tree (Samanea Saman) 3 Pink Cassia ( Cassia roxburghii ) 4 Amaltus (Cassia fistula) 5 Jacaranda (Jacaranda mimosaefolia) 6 Tamarind (Tamarindus indica) 7 White Champa (Plumeria alba) 8 Banyan (Ficus bengalensis) 9 Peepul (Ficus religiosa) 10 Cluster Fig (Ficus racemosa) 11 Mango (Magnifera indica) 12 Ashoka (Polyanthia longifolia) 13 Gulmohor (Delonix regia) 14 Copper Pod (Peltophorum pterocarpum) 15 Yellow Gulmohor ( Spathodia companulata) 16 Indian Coral (Erythrina indica) 17 Champak (Michelia champaka) 18 Bamboo (Bambusa arundinacea) 19 Kanchan (Bauhhinia purpurea) 20 Bottle Brush (Callistemon citrinus) 21 Putranjiva (Putranjiva roxburghii) 22 Bael (Aegle marmelos) 23 Silk Cotton Tree (Bombax ceiba) Prepared by: Aditya Environmental Services Pvt.

7. SOCIO-ECONOMIC ENVIRONMENT The proposed development is welcome for Navi Mumbai as it will create job opportunities & help improve commercial development in the city. The proposed development will enhance the property value within the core zone. It is also contemplated that employees and staff in this planned development area will have access to excellent facilities/ amenities and will not create a burden on public facilities (like public toilets or common water connections) is likely to enhance the cleanliness and improve public health in the area. Following are the proposed mitigation measures to be adopted during construction and operation stages of the proposed project.

7.1. Construction Phase The health and safety of the workers for the construction project will be ensured by: 1. Proper instructions about personnel safety will be given to all the labour working on the site by project manager before commencement of work. 2. The labourers will also be guided about the measures to be taken during emergency and accident like fire etc. 3. Safety equipment like gloves, helmet, mufflers etc. which will be made mandatory for use for all labourers on site. 4. Proper sanitation and water supply facilities will be provided to the labourers during construction phase.

7.2. Operation Phase During operation phase, precautions will be taken to ensure the health and safety of the proposed IT park. Periodic inspection and maintenance of all water storage tanks will be carried out at regular intervals to prevent outbreak of waterborne diseases.

8. ENVIRONMENTAL MANAGEMENT PLAN- ORGANIZATION & IMPLEMENTATION During construction phase, contractors as well as site-in-charge will be responsible for implementing all the mitigation measures recommended. Planting of trees on open spaces and road-side will be initiated during construction phase itself. An officer will be appointed by the project proponents to ensure monitoring and inspection during construction period.
