Contemporary Issues

Water, water every where but not a single drop to drink

It is projected that the 3rd world war will be for water

Climate change causing shift of seasons by one month

Nature works in a decentralized manner

“Dying Wisdom”-Dr Sunita Narain

Contemporary Issues

Limited Fresh water resources Increasing solid waste generation

Per Capita Waste generation rate in Indian cities ranges between 200 - 870 grams/day

Contemporary Issues

58% waste discharged into Yamuna in Delhi Increasing Air Pollution in Cities

Current Threat to Natural Heritage-across Indian Cities

o Depleting Urban Bio-Diversity

o Disturbed Ecosystem

o Concreting of Natural Streams

o Receding Ground Water Table

o Vanishing Wetland

o Contaminated Ground Water

o Sewage carrying Nalah

o Dried up lakes

Condition of Open Drains in Delhi

Ecology in Delhi

Contemporary Solution

Reduce, Reuse and Recycle

Decentralize systems in Neighborhood

Water Sensitive Plumbing

Integrate ecology and landscape to treat waste water, air

pollution and solid waste management

Constructed wetland to revive Rivers

Energy generation


In water closets:

• Dual flush WCs:

Full flush = 6 litres

Small flush = 4 litres

• Saves 33% of water when

we use the small flush

button


• Urinals that use no water at all, first invented by a German

named Klaus Reichardt use a trap insert filled with a sealant

liquid instead of water

• The lighter-than-water sealant floats on top of the urine

collected in the U-bend, preventing odours from being released

into the air.

• The system saves anywhere between 55,000 and 170,000 litres

of water per urinal per year.


• Instead of WC ,Water efficient

Urinals should be used at Public

Places like Hospitals, Airports,

Railway Station , etc.

• Latest technologies like Sensor

Flow ,Time Flush ,Automatic

Flush can be used.

Female Urinals


A person uses 40 lt. of water for bathing which is 30% of LPCD and

amount of water used by shower depends upon type of shower

,pressure and time period the shower taken

Showers can use anything from 10 to over 30 litres of water per

minute depending on the water pressure.

Shower restrictor limits the water flow to 9 litres per minute at 3 bar.

A typical 7 minute shower with water restrictor can save between 40

and 80 litres of water compared to having a bath.


Self Closing Taps

10-15 sec Sensor flow Taps

3sec- 30 sec Aerated flow restrictor

6 lt per minute at 3 bar
