Sewage could reduce country's energy bill

In a follow-up to my letter dated March 27, 2012 in which I suggested that steam could be used to generate electricity, I was pleased to discover that my suggestion would not be as difficult and costly as I had thought.

My area of concern was getting the sewage to a central area, but I have since learnt that the Soapberry sewage plant, located off the Mandela Highway, is where the raw sewage from Kingston is directed. It is also now being proposed that sewage to four wastewater plants in Portmore will be directed to the Soapberry facility.

Could prove beneficial

I believe these projects that cost taxpayers so much are not being utilised to their full potential so that benefits can be maximised. As I had suggested in a previous letter, sewage can be directed to digesters where methane, which is a flammable gas, is given off during fermentation.

The gas could then be used as the fuel for steam engines which would, in turn, drive generators for electricity production.

With development projects being so costly and most being implemented from borrowed money, I think it would be prudent to get them to a point where they can generate income to pay for themselves, wherever possible .
