SEPTIC TANKS

A septic tank is a key component of a septic system, a small-scale sewage treatment system common in areas that lack connection to main sewage pipes provided by local governments or private corporations. Other components, generally controlled by local governments, may include pumps, alarms, sand filters, and clarified liquid effluent disposal methods such as a septic drain field, ponds, natural stone fiber filter plants or peat moss beds. The project proponent has proposed 6 numbers of septic tanks of total capacity 260 m3 (260000 litres).

Capacity Sl. No. Location (m3) 1. Sarai Kale Khan 50 2. Sarai Kale Khan 50 3. Sarai Kale Khan 30 4. Mayur Vihar 40 5. Mayur Vihar 40 6. Power Grid 50 Total 260

The retention time of the septic tanks is 22 hours. Design Specification

A septic tank consists of three concrete tanks of adequate capacity.

Prepared by:- Mantec Consultants Pvt. Ltd. Page 49 Barapullah Elevated Road (Phase-III) From Sarai Kale Khan to Mayur Vihar(Phase-I), New Delhi Public Works Department (Govt. of NCT of Delhi) Conceptual Plan

One end of the first tank (anaerobic settling chamber) is connected to an inlet wastewater pipe and the outlet end of the tank is connected to aeration chamber .The relatively clear water passes to the clarification tank from which the clear effluent is disposed to the septic drain field with the help of an effluent pump.

Generally these pipe connections are made with a T pipe, allowing liquid to enter and exit without disturbing any crust on the surface. The design of the tank usually incorporates three chambers; each equipped with a manhole cover, and separated by a dividing wall with openings located about midway between the floor and roof of the tank.

The retention time (RT) of the septic tank is usually 1 to 3 days. A longer retention time is chosen to minimize cleaning frequency (running costs). A shorter retention time is chosen to minimise tank size and initial cost. Larger tanks allow the sewage more time to digest and thus reduce the load on the drainage system. Smaller tanks (< 6m3) need longer retention times due to increased turbulence (i.e. 2 or 3 days.)

Settlement Chamber

Wastewater enters the first chamber of the tank, allowing solids to settle and scum to float. The time taken by the wastewater is about 3 hrs after which the comparatively clear water (from the settling zone) enters to the aeration chamber. The retention time for this stage is taken as 5 hours.

Aeration Chamber

The settled solids are aerobically digested, reducing the volume of solids. The liquid component flows through the dividing wall into the third chamber i.e. clarification chamber where further settlement takes place. The retention time for this stage is taken as 7 hours.

Clarification Chamber

The excess liquid, now in a relatively clear condition, passes to the final pump chamber. The retention time for this stage is taken as 10 hours.

Final Pump chamber

The liquid from the clarification Chamber, then drains from the outlet into the septic drain field, with the help of an effluent pump. The effluent pump shall transfer the excess liquid to the water recycling tank for further aeration.

Water will be transported to Water recycling tank for further aeration

Schematic Diagram of a Septic Tank RAIN WATER HARVESTING

The storm water disposal system for the premises will be self-sufficient to avoid any collection/stagnation and flooding of water. Storm water drainage plan of the project is enclosed. The amount of storm water run-off depends upon many factors such as intensity and duration of precipitation, characteristics of the tributary area and the time required for such flow to reach the trunk drains. The trunk drains shall be located near the carriage way along either side of the roads. Taking the advantage of road camber (slope), the rainfall run off from roads shall flow towards the trunk drains provided at the side of the roads. Sprouts for seepage of water from the trunk drains shall be provided at the bottom of the drains at regular intervals. The location of the sprouts is being determined according to the slope of the cross- section. Thus, the storm water generated during the monsoons shall automatically get directed to the proposed trunk drains. The sprouts will allow the rainwater to fall freely in the Yamuna basin and its banks, thus resulting in ground water recharge. The Yamuna bank will thus act as the catchment basin of the rainwater.

1) Since the existing topography is considered congenial for surface disposal, a catchment basin is not required. The rain-water will automatically direct to Yamuna bank thus, leading to automatic ground water recharge.

Prepared by:- Mantec Consultants Pvt. Ltd. Page 59

Barapullah Elevated Road (Phase-III) From Sarai Kale Khan to Mayur Vihar New Delhi Public Works Department (Govt. of NCT of Delhi) Conceptual Plan

Staff and Contractors: Staff must be made aware of the importance of waste segregation and disposal, water and energy conservation. The awareness can be provided by periodic Integrated Society meetings. They would be informed of their duties. Environmental Audits and Corrective Action Plans: To assess whether the implemented EMP is adequate, periodic environmental audits will be conducted by the project proponent’s Environmental division. These audits will be followed by Correction Action Plan (CAP) to correct various issues identified during the audits.

ENVIRONMENT MANAGEMENT PLAN

The Environment Management Plan (EMP) would consist of all mitigation measures for each component of the environment due to the activities increased during the construction and operational phase of the project and these are discussed in later subsections.

The EMP is generally  Prepared in accordance with the rules and requirements of the MoEF&CC and CPCB/ SPCB  To ensure that the component of facilities are operated in accordance with the design  A process that confirms proper operation through supervision and monitoring  A system that addresses public complaints during construction and operation of the facilities and  A plan that ensures remedial measures is implemented immediately. The key benefits of the EMP are that it offers means of managing its environmental performance thereby allowing it to contribute to improved environmental quality. The other benefit includes cost control and improved relations with the stakeholders.

EMP includes four major elements:  Commitment & Policy: The management will strive to provide and implement the Environmental Management Plan that incorporates all issues related to air, water, land and noise.  Planning: This includes identification of environmental impacts, legal requirements and setting environmental objectives.

Prepared by:- Mantec Consultants Pvt. Ltd. Page 60

Barapullah Elevated Road (Phase-III) From Sarai Kale Khan to Mayur Vihar New Delhi Public Works Department (Govt. of NCT of Delhi) Conceptual Plan

 Implementation: This comprises of resources available to the developers, accountability of contractors, training of operational staff associated with environmental control facilities and documentation of measures to be taken.  Measurement & Evaluation: This includes monitoring, counteractive actions and record keeping. It is suggested that as part of the EMP, a monitoring committee would be formed by Public Works Department (Govt. of NCT of Delhi) comprising of the project manager /coordinator, environmental group representative and project implementation team representative. The committee’s role would be to ensure proper operation and management of the EMP including the regulatory compliance.

EMP FOR AIR ENVIRONMENT DURING CONSTRUCTION PHASE: To mitigate the impacts of PM10& PM2.5 during the construction phase of the project, the following measures are recommended for implementation:  A dust control plan  Procedural changes to construction activities

Dust Control Plan The most cost-effective dust suppressant is water because water is easily available on construction site. Water can be applied using water trucks, handled sprayers and automatic sprinkler systems. Furthermore, incoming loads could be covered to avoid loss of material in transport, especially if material is transported off-site.

Procedural Changes to Construction Activities Idle time reduction: Construction equipment is commonly left idle while the operators are on break or waiting for the completion of another task. Emission from idle equipment tends to be high, since catalytic converters cools down, thus reducing the efficiency of hydrocarbon and carbon monoxide oxidation. Existing idle control technologies comprises of power saving mode, which automatically off the engine at preset time and reduces emissions, without intervention from the operators. Improved Maintenance: Significant emission reductions can be achieved through regular equipment maintenance. Site Engineers will be asked to provide maintenance records for their fleet as part of the contract bid, and at regular intervals throughout the life of the contract. Incentive provisions will be established to encourage contractors to comply with regular maintenance requirements. Reduction of On-Site Construction Time: Rapid on-site construction would reduce the duration of traffic interference and therefore, will reduce emissions from traffic delay.

Barapullah Elevated Road (Phase-III) From Sarai Kale Khan to Mayur Vihar New Delhi Public Works Department (Govt. of NCT of Delhi) Conceptual Plan

EMP FOR AIR ENVIRONMENT DURING OPERATION PHASE: To mitigate the impacts of pollutants from vehicular traffic during the operational phase of the elevated road, following measures are recommended for implementation:  Vehicular emission controls and alternatives  Greenbelt development

Vehicle Emission Controls and Alternatives Footpaths and Pedestrian ways: Adequate footpaths and pedestrian ways would be provided at both the sides to encourage non-polluting methods of transportation.

Greenbelt Development Increased vegetation in the form of greenbelt around the site is one of the preferred methods to mitigate air and noise pollution. Plants serve as a sink for pollutants, act as a barrier to break the wind speed as well as allow the dust and other particulates to settle on the leaves. It also helps to reduce the noise level at large extent. Table given in green area section indicates various species of the greenbelt that can be used to act as a barrier.

EMP FOR NOISE ENVIRONMENT DURING CONSTRUCTION PHASE: To mitigate the impacts of noise from construction equipments during the construction phase on the site, the following measures are recommended for implementation. Time of Operation: Noisy construction equipments would not be allowed to use. The equipments will be of good make and will be properly maintained. Job Rotation and Hearing Protection: Workers employed in high noise areas will be employed on shift basis. Hearing protection such as earplugs/muffs will be provided to those working very close to the noise generating machinery.

EMP FOR NOISE ENVIRONMENT DURING OPERATION PHASE: To mitigate the impacts of noise from diesel generator set during operational phase, the following measures are recommended:  Greenbelt development Greenbelt Development BLUE BINS Increased vegetation in the form of greenbelt around the site is one of the preferred methods to mitigate noise pollution. Plants serve as an absorbing media for the noise. Table given in green area section indicates various species of the greenbelt that can be used to act as a barrier.

EMP FOR ECOLOGICAL ENVIRONMENT DURING CONSTRUCTION PHASE: Construction activity changes the natural environment. But the proposed elevated road shall also create a built environment. The project requires the implementation of following choices exclusively or in combination.  Restriction of construction activities to defined project areas only.  Restrictions on location of temporary labor tents and offices for project staff near the project area to avoid human induced secondary additional impacts on the flora and fauna species of the nearby areas.  Cutting, uprooting, coppicing of trees or small trees if present in and around the project site for cooking, burning or heating purposes by the labors will be prohibited and suitable alternatives for this purpose will be made.  Along with the construction work, a green belt would be developed with suggested native plant species, as they will grow to a full-fledged covered at the time of completion.

EMP FOR ECOLOGICAL ENVIRONMENT DURING OPERATION PHASE: Improvement of the current ecology of the project site will entail the following measures:  Plantation and Landscaping  Green Belt Development  Avenue Plantation

The section below summarizes the techniques to be applied to achieve the above objectives:

Green Belt Development Plan The plantation matrix adopted for the green belt development includes pit of 0.3 m × 0.3 m size with a spacing of 2.6 m x 2.6 m. In addition, earth filling and manure may also be required for the proper nutritional balance and nourishment of the saplings. It is also recommended that the plantation has to be taken up randomly and the landscaping aspects could be taken into consideration.

Prepared by:- Mantec Consultants Pvt. Ltd. Page 63

Multi-layered plantation comprising of medium height trees (7 m to 10 m) and shrubs (5 m height) are for the green belt. In addition creepers will be planted along the road sides to enhance its insulation capacity.

Selection of Plant Species for Green Belt Development The selection of plant species for the development depends on various factors such as climate, elevation and soil. The plants would exhibit the following desirable characteristics in order to be selected for plantation 1. The species should be fast growing and providing optimum penetrability. 2. The species should be wind-firm and deep rooted. 3. The species should form a dense canopy. 4. As far as possible, the species should be indigenous and locally available. 5. Species tolerance to air pollutants like SO2 and NOx should be preferred. 6. The species should be permeable to help create air turbulence and mixing within the belt 7. There should be no large gaps for the air to spill through 8. Trees with high foliage density, leaves with larger leaf area and hairy on both the surfaces shall be preferred. 9. Ability to withstand conditions like inundation and drought. 10. Soil improving plants (Nitrogen fixing rapidly decomposable leaf litter). 11. Attractive appearance with good flowering and fruit bearing. 12. Bird and insect attracting tree species. 13. Sustainable green cover with minimal maintenance.

Avenue Plantation 1. Trees with colonial canopy with attractive flowering 2. Trees with branching at 7 feet and above
