37 APRIL 2017

PROPOSED EXPANSION OF MULTISTORIED RESIDENTIAL COMPLEX CHAPTER 3 - PROJECT DESCRIPTION

Working Principle

Mechanical Composter converts the organic waste into odorless, pre-compost manure in 15-20 minutes. The organic waste, freed from foreign particles is fed into MC. The shredder reduces the organic waste into the optimum particle size for composting. Then it is mixed with moisture absorbing materials and Useful micro-organisms. This mixture is then blended for a homogeneous mixture and is converted into pre compost manure in 20 minutes. The pre compost manure is then fed into aerated compost blocks or 12 - 15 days.

The compost blocks or piles are specially designed for the pre-compost manure to have proper aeration and suitable environment to mature. The final manure will be rich in nutrients and used for the development of green belt. The technical specification of the Mechanical Composter is given below in Table.

Salient Features of Organic Waste Converter (OWC)

 Quick, easy to operate, less space requirement and odor free manure compared to other waste conversion process  Immediate and hygienic disposal of food waste  Waste minimization strategy followed by 3R Technique (Reduce, Reuse, Recycle)  Savings on Purchase of Manure for landscape  Savings on Waste Disposal Expenses  Elimination on the usage of chemical fertilizers  Carbon credit revenue in the future

3. 2 RAINWATER HARVESTING & 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.

3.8.1 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.

3.8.2 Rainwater Harvesting Network

Rain water harvesting trenches 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. The depth of the trench will be 1.2 m and the width will be 0.9 m. The trench will be filled with rounded pebble 25 to 40 mm size. The sectional detail of the proposed rain water recharge pit is provided in Figure 3.2. The existing rainwater harvesting structures are given in Figure 3.3.

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.

39 APRIL 2017

PROPOSED EXPANSION OF MULTISTORIED RESIDENTIAL COMPLEX CHAPTER 3 - PROJECT DESCRIPTION

4. ENVIRONMENTAL MANAGEMENT PLAN

4.1 ENVIRONMENTAL MANAGEMENT PLAN (EMP)

Environmental Management Plan (EMP) deals with evaluation of significance of unavoidable or residual impacts following mitigation and the proposed monitoring. The Environmental Management Plan (EMP) is needed to ensure that the mitigation measures specified will actually be complied with when the project is approved for implementations.

The Environmental Management Plan (EMP) need to be integrated in overall project planning process covering all phases of project cycles i.e, location, design, construction and operation. Management by provision of necessary safeguard in planning of the project itself can lead to reduction of adverse environmental impacts due to project. This chapter spells out the set of measures to be undertaken during project construction and operation to reduce or mitigate or bring down the adverse environmental impacts to acceptable level based on the proposed Environmental Management Plan.

The most reliable way to ensure that the plan will be integrated into the overall project planning and implementation is to include the plan as an integral component of the project. This will ensure that it receives funding and supervision along with other investment components. For optimal integration of EMP into the project, there will be link for:

 Funding  Management  Training  Monitoring

The purpose of the first link is to ensure that proposed actions are adequately financed. The second link helps in embedding training, technical assistance, staffing and other institutional strengthening items in the mitigation measures to implement the overall management plan. The third provides a critical path for implementation and enables sponsors and the funding agency to evaluate the success of mitigation measures, as part of project supervision and as a means to improve future projects. For every use discussed in the above sections, the implementing agency as well as staffing, equipment, phasing and budgeting have been presented as far as possible. All required funds will be channeled through the project authority. The Environmental Management Plans have been prepared and discussed in subsequent sections.
