3.7.2 Techniques for disposal of generated waste
Organic Waste Converter
The Mechanical Composter (MC) is the perfect blend of nature’s gift to mankind -
decomposing bacteria and sheer engineering marvel, complementing each other to
produce odorless pre-organic compost in 15 minutes alone. The solution involves a
biomechanical process that will be a boon to resorts, hotels, temples, markets, hospitals,
townships, industrial canteens and clubs and resorts. The machine, occupying a small
area of yours is a tool to challenge the dumping site and we invite you to pioneer this
move for a cleaner and better environment.
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.

3.8 RAIN WATER HARVESTING AND STORM WATER DRAIN
The rapid growth of population and ever increasing demand for water has necessitated
the revival of rain water harvesting technology. More thrust is given in urban areas as
the demand is increasing day by day. The rapid growth and development in urban areas
have led to depletion of surface water sources. This has also resulted in over exploitation
of sub-surface sources like wells for drinking and industrial use, resulting in dropping of
water levels and drying up of bore wells or sea water intrusion, because of imbalance of
inflow and outflow equation for sub-surface water.
The rapid urbanization has also introduced reduction in original permeable ground
surface because of pavements, roads and construction of storm water drains for aiming
to drain the rain water as quickly as possible to nearby natural stream, river or sea to
avoid flooding of grounds and disruption in traffic. These surfaces and quick disposal
gives no time for rain water to percolate naturally into the ground to replenish the water
bodies / sub-surface aquifer, causing the decline in water levels or drying up of wells.
The results of man-made crisis can be seen as global warming and change in climatic
conditions.
The rains have become more irregular because of disturbance in natural cycle and
therefore do not reach when one wants them. Also, the quantity of rainfall is erratic,
reduced and uncertain. Water is not becoming physically scarce, but also financially
expensive. It is therefore necessary to conserve and augment the renewable natural
ground water resources, as last chance for survival, realizing that natural resources are
not unlimited if they are exploited beyond certain limit.
BENEFITS OF RWH AND ARTIFICIAL RECHARGE STRUCTURES
Rain Water Harvesting (RWH) has multiple beneficial factors which are listed below:
1. Gradual increase in the ground water table, especially during summer.
2. Lower operating cost for ground water supplies by lessening pumping lift.
3. Improvement in the quality and taste of water. Quality in terms of changes in
Salinity, Total Dissolved Solids (TDS), Iron, etc.,
4. Prevention of Water stagnation
5. Cracks in walls of the building will minimize
6. Prevent dewatering of all or part of the underground reservoirs.
7. Reduces incidence of premature abandonment of wells.
8. Prevents Sea Water Intrusion that threatens the Coastal areas
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. 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.
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 62 rain water harvesting pits will be constructed. The quantity of
run-off water potential for the proposed construction project is given below. The
rainwater harvesting arrangement helps in replenishing the underground water column
and soil lithography is given in Table 3.10.

Rain Water harvesting will be done through the trench which is provided with the pebble
bed of 1500 mm width & 1000 mm depth all around the building which will be filled with
rounded pebble of size 25 to 40 mm. The path ways will be graded to drain into rain
water drain channels proposed in main drive ways/ roads, so that rain water from the
terrace flow over this pavement and spread into the pebble bed.

objective of the rescue and firefighting services is to save lives. For this reason, the
provision for means of quick dealing with an accident or incident occurring at, or in the
immediate vicinity of, any building, assumes primary importance because it is within this
area that there is the greatest opportunity of saving lives. This must assume at all times
the possibility of, and need for, extinguishing a fire which may occur either immediately
following an accident or incident, or at any time during rescue operations. In the design
