Wastewater Generation & Treatment
The entire Sewage Treatment Scheme is based on the principle of Fluidized Aerobic Bioreactor
(FAB) Process with diffused aeration system. The treated effluent coming out of the STP is used
for gardening and other purposes. Capacity of the STP is 250 KLD.
Sewage Treatment Technology
FAB Technology
The M/s Ambuja Realty Development Ltd. is treating sewage of commercial project in sewage
treatment plant which works on Fluidized Aerated Bed Reactor (FAB) processes which has
improved reliability, simplified operation, and requires less space than traditional wastewater
treatment systems.
Sewage after passing through the bar screen, grit chamber, oil and grease separator and
equalization tank is pumped to Ist Stage FAB Reactor, where initial removal of organic matter
takes place. In this Reactor special type of FRP floating media is provided for proper growth of
bio-mass inside the reactor. Bio-mass attached with the media reduces the organic load present in
the sewage. Aeration by means of Air Blower is provided for effective mixing & aeration
necessary for proper growth of micro-organisms. Coarse bubble Diffusers is provided for aeration
inside the Reactor. For proper growth & maintenance of microorganisms special bacteria culture
(EM) is dosed periodically.
The sewage comprising of the biological flock from FAB Reactor-I overflows into the second FAB
Reactor-II where further oxidation of organic matter takes place. Overflow of this tank passes
through a Tube Settler where the solid mass settles down at the bottom. This underflow sludge is
recycled back by the Sludge Pump to the FAB Reactor to maintain the population of micro-

organisms, whenever required. Excess sludge is pumped through Filter Press, where sludge gets
concentrated & sludge cake are used as manure.
Overflow water from Tube Settler is collected in a chlorine contact Tank from where it is pumped
through a Multi Grade Filter, Activated Carbon Filter to the treated water tank.

Volume reduction is 80 – 90%. Hence 100 kg of wet waste is converted into 10 – 15kg of
compost, reducing your space requirements for compost storage also.
Most organic matter can be composted within 2 days, but it is advised to collect the compost
once in 4 - 5 days. If small amount of plastic waste is put in by oversight, it will come out
clean &dry along with the compost. But it is not advisable to put in such plastics waste by
more than 1%. This is the only composting system that can take in gravy/ sambar also.
Since the digestion is aerobic, there is no methane/ ammonia formed from the nitrogen
content of the food and hence odourless. o It is almost completely noiseless, since there is no
shredding/ cutting
This is the technology and that is adopted by most big apartment complexes, offices and
campuses in developed countries to process their wet waste. India has also started adopting
this in a major way while REDDONATURA is bringing the product for the first time to
Eastern India.
Rain Water Harvesting
Project is operational project and rain water harvesting is implemented, based upon the
“Rain water harvesting and conservation” manual by Govt. of India Consultancy Service
organization Central Public Work Department, 2002. The method of harvesting rainwater is
storage of rainwater as well as subsurface recharge from the building roof. It does not include the
collection or recharge of rainwater from ground surface. Rainwater pipes that collect water from
the catchments (rooftop) are stored to three pairs of settlement chambers. The collected rainwater

used for secondary purposes like street cleansing and gardening etc. The expected availability has
been assessed and mentioned below:
Rainwater Harvesting Potential = Annual Rainfall (mm) X Collection Efficiency
Mean Annual Rainfall = 1384.9 say 1400 mm & mean No. of Rainy days in a year = 62
(Source: Indian Meteorological Department, Pune, 1951-2002)
Area of Roof Catchment = 4,349.35sq.m say 4300 sq.m
Height of Rainfall = 1.4 m
Volume of Rainfall over the Roof = 4300 sq.m X 1.4 m
= 6,020 cu.m (say A)
Considering roof catchment is having tiles or equivalent finish so that co-efficient for roof surface
can be adopted as 0.85 and
Considering another co-efficient for evaporation, spillage and first flush wastage as 0.80;
Approximately annual effective harvested water quantity be considered as
Rainwater Endowment of the Area (A) X 0.80 X 0.85
= 6,020 X 0.80 X 0.85 litres = 4,093.6 kL.
Mean Rainfall during monsoon = 1277 mm & mean No. of Rainy days during monsoon = 62(from
June to September)
(Source: Indian Meteorological Department, Pune, 1951-2002)
Considering duration of monsoon as 120 days (June – September), daily average rainwater
available from building roof is 4094 / 120 = 35 KL.

Calculation for determining Capacity of Storage Tank
As already stated that in Raipur District, Mean Rainfall during monsoon = 1277 mm & mean No.
of Rainy days during monsoon = 62(from June to September);
Average daily rainfall during monsoon, 1277/62 = 20.59mm say 21mm.
Thus, peak hourly rainfall can be considered as 3 times of average daily rainfall i.e. 21mm X 3 =
63mm or 0.063m.
The capacity of recharge tank is designed to retain runoff for at least 30 min rainfall of the peak
intensity (60mm/hr).
Thus, capacity of the tank is: V = A X r X C
V = Capacity of Tank, A = 4300 sq.m (Available rooftop area), r = 0.03m (30 min rainfall of peak
intensity), C = 0.85 (Runoff coefficient of rooftop)
Thus, V = (4300X0.03X0.85) cu.m = 109.65 say 110 cu.m. Capacity of tank = 120 cu.m.
Hence, in this project, a Storage & Settlement tank, having capacity of 120 cu.m), is provided.
Overflow from the tank is discharged into the 3 pits located in the premises.
Energy conservation
Construction Phase
The external wall of the building blocks is constructed with 250mm thick double brick
layer, both side plastered (expected U-value = 0.44 W/m2-°C)
The roofs of the building blocks was constructed with typical 100-150mm thick R.C.C. slab
with cement screed and clay tiles (expected U-value = 0.263 W/m2-°C).

Glass panes are 4mm to 6mm thick depending upon the exposure of the surface to the sun.
In some of the areas of building façade, double glazing with reflective coating was also
used. Expected U-values of single glazing clear glass and double glazing reflective coated
glass are 3.3 W/m2-°C and 0.54W/m
s-°C respectively.
Paving materials are light coloured and porous. The pavement might be of open jointed
paver blocks partially depending upon the landscaping scheme. Use of high albedo or
reflective pavements was considered at the time of construction.
Proper insulation of roof was provided to achieve desired thermal comfort. Use of light
coloured, reflective roofs having an SRI of 50% or more is incorporated.
Fly ash bricks, paver blocks and cement were used following MoEF Notifications.
Use of Ready Mix Concrete was given priority.
