ONE of the sources of the spread of polio and dengue virus in Pakistan is its terrible sewerage system. This could be avoided by underlying 10 feet or more diameter sewerage pipelines.

Here bridges are made on a pattern that any uncontrolled vehicle can easily plunge hundreds of feet down and roads are vulnerable for commuters and for sewerage.

In underpasses, sewerage and gutters are pathetic and pedestrian bridges are most uncomfortable for pedestrians. For example, instead of constructing a 30-40 feet high pedestrian bridge, why not construct an eight or nine feet pedestrian underpass?

It has many advantages: first, it will greatly reduce height; second, patients and senior citizens can have easy access to it and, third, it will generate revenue, which can meet the maintenance and surveillance cost.

River and ravine bridges should be built such that their side walls are thick and high and rounded so that no one plunges down.

I request the prime minister and all the chief ministers, who are all public servants, to take measures for the betterment of the masses.
