Comprehensive Water Management at

Classic Orchards

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.

STATUS OF SOURCES OF WATER AS ON AUG 2011 BWSSB water connection to each

house in the layout

Common Bore wells – lying redundant

OpenWell – used only for common area gardening

STP – directly let-out into drains

Presented large scope for improvement.

EXISTING ECO-FRIENDLY PRACTICES AS ON 2011

No individual borewells were allowed since the launch of the layout.

STP to recycle water was provided and partially the water was used for gardening purposes.

Open well water was being used for club-house non-potable activities.

OPPORTUNITIES TO GO GREEN - 2011

70 acres land – Brings promises with it! Large scope to start inhouse composting in large

scale. Extend green cover and arrest soil erosion. Recycle STP water and harvest rain water. Explore alternative power source like Solar and

wind turbine.

ECO CONSCIOUSNESS DRIVE: UNDERSTATING THE PROBLEM

Relook at the water consumption patterns 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.

ECO CONSCIOUSNESS DRIVE: STP - REHAUL

Step 1: Introduced 2 extra storage tanks for STP to arrest loss of 70KLD of recycled water.

Step 2: STP processed water used for gardening purposes.

Step 3: Excess STP water is let-out to recharge ground water table.

Going Forward: Give processed STP water connections to all individual

households for gardening and other non-potable uses. Provide water for construction activities.

ECO CONSCIOUSNESS DRIVE: RAINWATER HARVESTING POTENTIAL

Area (sqm) Run-off for average rain (30 mm) (KL)

With the projected rainwater endowment, 100% water self-sufficiency is possible with 30mm rainfall per annum.

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.

ECO CONSCIOUSNESS DRIVE: EXTEND GREEN COVER

Undertook plantation drive by involving children and residents of the layout.

Encouraged households to do in-house composting and introduced organic composting at community level.

Created environment consciousness amongst residents.

Garbage segregation. Encourage eco-friendly Ganesha

idols. Street plays and demos to create

awareness.

ECO CONSCIOUSNESS DRIVE: OTHER GO GREEN INITIATIVES Started the initiatives to go green.

Create awareness to conserve water amongst residents

Focus on waste segregation and in-house organic waste composting.

Encourage households to process wet-waste by introducing various in-house composting methods.

Road humps are designed and re-done to capture most of the rainwater and direct it to the drains.

Experimenting to control soil erosion along the roads by planting bushes and wild grass by the edge of the road.
