This Slideshare is about is about Forward thinking Gated Community who took a bold initiative to conserve and use the STP for their gardening and construction activities in their community.
This Bangalore Community which is located on Bannerghatta Road is spread over 70 acres also uses Rain Water Harvesting with Open Wells, and aims at 100% Water Self Sufficiency by 2018!

Classic Orchards - Comprehensive Water & Waste Management in a 500 Plot Community
1. PRESENTS
Comprehensive Waste and Water Management at Classic Orchards
Presented in the "Self-Sufficient Apartment Communities - An Open House".
Conducted on 15-June-2013, by The Alternative and ApartmentADDA.
2. BRIEF INTRODUCTION :CLASSIC ORCHARDS
Gated Community located on Bannerghatta Road
Layout is spread over 70 acres and has about 500 plots.
Presently about 150 independent houses (30%) have
been constructed and occupied.
Current population of approx. 700 occupants. Expected
to grow by 25% in next 1 year.
3. SITUATION 2 YEARS AGO:
BWSSB water connection to each house in the layout
5 Common Bore wells – back up
Open Well – used only for common area gardening
STP – Processed and let-out into drains
Presented large scope for improvement
.
4. ECO DRIVE: STP - REHAUL
Step 1: 2 extra storage tanks for STP to
arrest loss of 70KLD of recycled water.
Step 2: STP processed water used for
gardening purposes.
Going Forward:
Supply processed STP water connections to
all individual households for gardening.
Provide water for construction activities.
7. ECO DRIVE: ZERO WASTE DISCHARGE
Street plays, guest lectures
and demos to create
awareness.
Waste segregation by
households and organic
composting at community
level.
8. ECO CONSCIOUSNESS DRIVE: EXTEND GREEN COVER
Tree plantation by children
and residents of the layout.
Control soil erosion along
the roads by planting
bushes and grass.
9. ECO DRIVE: UNDERSTATING THE PROBLEM
Initiated a survey with Biome Environmental
Solutions:
CO consumed much more than average
consumption of Bangalore per household.
270K sqm area of CO, potential of 143K KL of
rainwater harvest at 970mm of annual rainfall.
Translates into not just 100% self-sufficiency, but
also twice the water surplus as per current
consumption.

With the projected rainwater endowment, 100% water self-
sufficiency is possible with 30mm rainfall per annum.
11. ECO CONSCIOUSNESS DRIVE: RAINWATER
HARVESTING PLAN
Use existing wells as collection point for rainwater flowing
through the open drains.
All open drains by the roads lead to 2 open wells within the layout.
To facilitate the ground water discharge, open wells have been recently
desilted.
Identified 40 locations as recharge wells to improve ground water
table.
3 recharge wells have been commissioned to study the water
percolation into the ground.
Club-house rooftop rainwater is being reutilised by collecting the
water in tanks.
Water collected in these tanks is used for housekeeping and gardening
purposes of the club-house.
