WHY DELHI NEEDS AN INNOVATIVE MEASURE TO BRING DOWN THE RESPIRABLE SUSPENDED PARTICULATE MATERIAL (RSPM) TO IMPROVE BREATHABLE AIR QUALITY ?

THE ONLY CHEAP AND WORKABLE  SOLUTION IS WASHING DOWN THE  RSPM AT REGULAR INTERVALS  BY USING WATER/RAIN LIKE SPRAYING MASTS BECAUSE THE OTHER EFFORTS WILL ONLY REDUCE AND THAT TOO GRADUALLY AND WITH LONGER TIME FRAMES.

THE IDEA

The idea being projected here is original thought of the author and it has presently not  been used anywhere in the world.(AS FOUND OUT BY GOOGLING THE INTERNET)

The Method

Will be using spraying water from the height of FIFTY TO HUNDRED  feet  USING SPRAYING HIGH MASTS SO as to cater to both sides as well as covering maximum area to bring down the RSPM. As the height  of SPM (Suspended Particulate Matter) of varying sizes from .1 micron to 10 microns are found at varying heights from 10 m to 1500 meters.

Provision of Water for spraying

The initial water will have to be brought from the pumps and sprayed at most polluted spots say after every 30 minutes or depending  upon  concentrations of the RSPM levels..  Later the rain water from the roads which goes waste in to the storm water or wasted on to the side of berms/ gutters can be harvested. This water after due settling and de-silting and filtering same can be used for this spraying from the high masts at SPMs.

FINANCIAL IMPLICATIONS

This system which can be first  made as a prototype and tested. As this system is easy to make , is non complicated and can be replicated very easily. the cost will only be worked out at pilot level and will reduce further with economy of scale. The cost will not be prohibitive as well its cost to benefit ratio will make it look very negligible to the costd we pay for air pollution its monitoring and control.

THE SPOTS WHERE THESE SPRAY MASTS  WILL BE MOST  EFFECTIVE

The  traffic light points can be the spots where these can be deployed as here as normally about 100 vehicles in each direction stop for 1 to 3 minutes .So on an average  300 to 400 vehicles wait for 1 to 3 minutes  at the traffic signals asat any given point of time only one direction out of four gets a  green light to move on and the remaining   three which  have almost 100 vehicles approximately waiting in the remaining three non moving corridors. Most have their engines running adding to the already polluted traffic light areas.

Similarly the stretches where diesel vehicles are more and the traffic movement is slow are likely going to the areas where it is going to be most effective.
