The Sewage Trap

Water, sanitation and hygiene expert with a proven track record, Chandrasekaran J. writes about implications of conventional sewage treatment methods. 

Water is a simple liquid to understand, but the pollution in water has become more difficult to decipher! All pollutants by all means; air, solid, and liquid have proliferated into streams, rivers, oceans and have made a mess out of water and nature as well.

On their own part, the big multinational companies, with their huge research and development wings, consciously or unconsciously, have dumped chemicals, added motors and aerators to oxidize water thereby complicating more the system of cleaning. The existence of some players in the water treatment industry brought about different innovations that are believed to come from “water solution experts”.

However, our “water solution experts” conveniently forgot that their systems are chemically endangering more flora and fauna; electricity consumption is going up and also the complexity of maintaining the motors and mechanical stations are adding to the woes of users and the maintenance personnel in any building apartment or establishment.

Another disadvantage from these innovations is that these systems which are called STPs occupy huge spaces and land which has become also a costly commodity to buy or own.

Many biological plants, succulents, and root creepers have for ages been natural cleaners of toxins and pollutants in water, whether it is sewage caused by human excretion or any toxic pollutants.

While trying to understand why so many complexities arose in understanding and treating sewage, the tangible answer may look like plain talk of cleaning water. The frank talk is that the ideal situation in many places is that these Sewage Treatment Plants (STPs) have become money guzzlers and a big worry for maintenance. There is also the non-availability of parts, machinery, and chemicals as well.

The wastewater treatment completely using biological means is now trending, and this cuts down usage of huge machinery, electricity and space, concludes Chandrasekaran. The whole system operates in four stages - and in this article, he has broken them down in detail.
