Prevention is better then cure, I agree but still ideas like getting less showers and not shining your car with excessive use of water type phenomenon have all become history. I say, why not bring the unsuitable water back to drinkable form or if not that we could irrigate farms from it. As we all know that flowing water is pure until its assimilative capacity is not exceeded. But i certainly have an idea where by the assimilative capacity will increase and water will travel in streams and river as clear as ever. This idea is particularly for the streams that flow down a mountain and pass through a city. IDEA no1. A small storage not big enough to cause any flood must be constructed at the source which will help regulate the amount of water throughout the channel as the sanitary water enters it while passing through the city. This little extra amount of water would help in decaying the organics. IDEA no2. Few small filtration plants not many I-e only 2 must be built at some distance which will reduce the threats to pandemics. IDEA no 3. The best and easy thing to do would be to add an incline that is increasing the slope downwards. The faster the water moves, the cleaner it gets. Benefits Aesthetic beauty of the city will recover and people can use the area for recreational purpose. Sanitation would not be visible. Less smell Less Diseases.
