Water Pollution From Households
A Presentation By Karan Rajpal
Households as a source of water Pollution
The combined effect of an entire city or town can be serious.
Its Effects
Eutrophication, Sedimentation, and Contamination with chemical pollutants.
Kitchens and Water Pollution
Prevent flushing down oily and greasy substances through kitchen basin
Kitchens and Water Pollution
Reduce overuse of soaps and detergents. The phosphates in the cleaning agents can aid eutrophication in surface water bodies, if the waste from your home goes untreated to a lake or a stream.

Water Pollution from bathrooms
Use natural soaps and shampoos as far as possible. Not only are they good for your skin and hair, they reduce the amount of phosphates in the waste water. Try ‘shikakai’ instead of shampoo and ‘besan’ instead of soap.
Try to use natural cleaners for sinks and toilets.
Water Pollution from bathrooms
Excessive organic wastes and phosphates in wastewater can cause eutrophication of lake
This results in the death of the entire lake ecosystem
Proper Chemical Use, Storage, and Disposal
• Paints, used oil, cleaning solvents, polishes, insecticides, and other hazardous household chemicals.
Can end up in nearby water bodies.

Proper Chemical Use, Storage, and Disposal
Donate medicines that you have no use for but still have a way to go before expiry.

Segregate your wastesSegregate your wastes. Compost food wastes. Give away every bit of recyclable waste to the k a b a d iw a l la h . This includes paper, junk mail and envelopes, pet bottles, glass containers, plastic boxes and lids, plastic covers in which your groceries are packaged, metallic items etc. The kabadiwallah network will ensure that these wastes are recycled, instead of them ending up in a landfill or a drain and contaminating groundwater or blocking storm water flows.
When rainwater falls on a municipal solid waste dump, chemicals in the dump mix with the rainwater and this polluted water seeps into groundwater aquifers over time.
Recycle and Dispose of Trash Properly
Non-degradable products – Plastic Bags, Disposable Diapers
Other Dangerous Waste – Drugs and Medicines
When it rains, clean rainwater gets polluted with all these
contaminants.
The polluted rainwater flows into lakes and streams and impacts the water quality of these water bodies as well.
Paved surfaces like sidewalks, parking lots, roads, and
driveways have oil, grease, garbage, dirt and a host of
other pollutants.
Between Households
``
Harvest as much rainwater as you can from your rooftop, before it gets mixed with contaminants from the street or the storm water drain.
Rainwater Harvesting
Look for alternatives to cement and concrete for paving the front yard. Use materials that will allow the rainwater to seep through into the ground.
Rainwater Harvesting
In The Garden
Avoid over-watering lawns and gardens.
Use organic manure and herbicides instead of chemical fertilizers and pesticides
Increases the leaching of fertilizers into groundwater
Grasses and natural ground cover can be attractive and practical substitutes for asphalt driveways, walkways.
But pesticides and fertilizers used on these lawns, leach into groundwater and pollute it.
In The Garden
Non-Native plants need fertilizer and extra water
They can increase the potential for higher runoff volumes, increase erosion,and introduce chemicals into the path of runoff
Check with the forest department in your town or city for a list of plants native to your region.
So let’s get together andMake a D ifference
