Jamaica Has Copious Water Resources, But....

Jamaica often has pervasive water issues. Additionally, announcements by the national water commission (NWC) of impending/ongoing water restrictions are not surprising. In fact, the aforementioned step may be seen as prudent, seeing that we are now in our primary dry season. Jamaica's primary dry season generally spans the period, December through April.

However, despite perennial problems with water supply and distribution, Jamaica is not short of water. This may seem paradoxical, but Jamaica has copious water resources, enough to supply present and future demands. You need not take my word for it. The water resources authority (WRA), in news covered by the Jamaica Observer, entitled We Have Enough Water, suggests that Jamaica uses fewer than 25 per cent of Its annual water reserves. Providing meaning to the term "land of wood and water"

The article went on to state, and I quote "We are only using 22-24 per cent of our available water resources. Roughly 90 per cent of our reserves are tied up in grounwater,". The former figure may be shocking, as many Jamaicans are living without a reliable water supply. In fact, data from the water commission evince that, 30 per cent of Jamaicans receive water from standpipes, water trucks, community catchment tanks, etc.

Additionally, Jamaicans with house connections are not unfamiliar with ad hoc water supply. To give an example, I will quote from a Jamaica Observer article entitled, Manchester Councillors Scold NWC "the parish needs 22 million gallons of water per day, with the capital Mandeville requiring six million gallons. However, on average in 2006, the parish is receiving only eight million gallons of water daily, two million of which goes to Mandeville."

What Can, Or Is Being Implemented To Alleviate Some Of The Problems?

Leaks may seem innocuous. However, 34 per cent of piped water is lost, attributable to leaks. The declaration was made during a Public Administration and Appropriations Committee (PAAC) sitting in 2012. The leaks are exacerbated by theft. This was also revealed in the PAAC sitting, approximately 68 per cent of NWC's water is considered non revenue water. In this regards, the K-Factor programme is being implemented to reduce non revenue water, and increase accessibility to reliable water resources.

However, the programme shall not solve all the inefficiencies of the NWC. A major inefficiency, is NWC's energy bill. This is said to be Jamaica Public Service Company's (JPS's) biggest customer, with a monthly bill of approximately J$ 500 million, J$ 6 billion annually. An untenable figure. Plus, the high energy cost limits the amount water that may be pumped economically, especially in mountainous areas such as Mandeville, Manchester. With that said, the NWC should use renewable energy where applicable, so as to significantly lower the cost of pumping water. A long-term solution, such as building a dam should also be considered, Jamaica's last major was built in the 1940s.

Instituting these measures should go a long way to provide, efficient and accessible water to the masses.
