Waste Water Management - Inputs Sought

India currently only treats 30% of the waste water it generates while the rest is released into open drains or straight into the ground. Lack of treatment options lead to two problems: not treating wastewater (i.e. sewage) before discharging it into waterways pollutes the source, often rendering the water unusable for drinking.

The water intended for drinking is withdrawn from this same source, and again not adequately treated, creating significant public health problems: 21% of communicable diseases in India stem from unsafe water.

With this post, we seek all your inputs on how India could effectively treat its waste water. If this happens, the country would be able to significantly expand its available water supply, both for potable and non-potable use. Our economy, industry and most importantly, our people, would reap the benefits.

We look forward to your inputs!

To my opinion in cities this problem can be divided into 2. One is water wastage by none other than the miads and second is waste water treatment. more  
India cannot afford to install expensive waste water management system prevalent in many other countries. Alternative solutions as follows: a) Natural treatment of waste water: In the past, in many cities like Kolkata, waste water used to accumulate in large ponds. These ponds acted as a fish breeding ground. Such fishes along with natural biocides (bacteria and algae) used to get rid of the toxicity of the water and render them fit for industrial as well as horticultural use. More research in this front can bring in better results. b) Industries should be barred to tap ground water for their use. Only recycled water should be provided to them. Aim for zero discharge technology. c) All housing societies should have dual water supply and storage system. One should be supplied with grey water for use in toilet flushes. Other system should have clean ground water for kitchen, washing, bathing etc. d) Use specialized natural filters (sand beds) for treatment of waste water prior to discharge into water bodies (rivers or lakes) or groundwater recharge wells. These sand beds are not expensive and can be developed through simple technologies. I am not a water treatment specialist. However, any of the above leads can be explored further by specialists in this field and a cost effective, fit-for-purpose solution can be developed. more  
everybody to use water conservatively. is there an alternative for water ? more  
We must not progress by creating wastes. Large scale pollution must be immediately stopped. Large scale entitities should not be allowed to dump pollutants into waters, air and soil without treating them. Waste management should become an attitude till the micro possiblest level. We should become zero waste producers at macro and micro levels. Waste will always be produced but waste (even human and animal waste) can be turned into utility products (segragation,composting, shredding, recycling, reducing, decomposition etc.) Safai Karamcharis should be given the required equipments/clothing etc. to handle wastes and as well as also proper training. more  
Waste water must be treated before dumping it into river or any other place. Govt. must make it mandatory and any violation should be punished strictly. No new approval should be given where such a provision is not proposed and must be checked for its implementation before start of industrial or any such unit. Concept of common affluent treatment plants in industrial hubs and such other places should be implemented on Public Private Partnership basis it. to ensure waste water treatment before dumping more
