Water Crisis In Kalutara District & Its Vicinity Areas

It is generally observed that most of the people living in Kalutara District happen to face severe water crisis causing endless sufferings and hardship in the drought season particularly during the period of March and May. Based on the climate patterns in our country, we may consider those periods as summer due to high humidity or dry weather. Salinity of water is one of prime feature that people in Kalutara District experience during these periods. Subsequent trend that we see during these periods is that the National Water Supply and Drainage Board is always rushing to announce not to drink tap water due to salinity as a result of sea water intrusion into Kalu Ganga River. This announcement has become annual routine that people living in Kalutara district has been familiarised during this period. Probably, this may be the case of other coastal areas too. 

As we all know, Kalutara District, which is located in the wet zone, is much popular for its green atmosphere and tranquillity of nature due to ample rainfall with compare to Colombo or Gampaha districts in the Western province. This district has been encompassed by most exciting features such as stunning blue coastline, rubber and tea plantations, rural areas with cool and misty mountains and having popular historic and religious places. Apart from these features, one of fresh water natural lake in Sri Lanka, Bolgoda Lake is also located in this district. But unfortunately people living in this district have been compelled to consume salty water particularly during drought season in spite of the fact that this district has ample water resources and rains forests apart from Kalu Gange River. 

Meanwhile, authorities point out the drought season as the prime reason for salinity of water in Kalutara district since the water level in Kalu Gange River, from which the drinking water has been distributing, happens to go down. Perhaps, this may be the immediate reason for sea water intrusion into river water. But, many experts say that the drought season alone could not have been the immediate cause for the sea water intrusion. Rather, while observing the nature of the crisis and delving its root causes, we can somewhat perceive that this plight seems to be an accidental unlike periodical changes and also there should be some other factors have been contributing to this crisis in this area. 

According to some experts, this crisis is therefore an artificial and has gradually emerged due to various unattended causes. As said previously, the drought would be a reason to certain extent, but many believe that drought season should be the surface of the crisis and the root causes are underneath. They claim that mechanised sand mining operation, hunting for non-renewable ground water and its aquifers and water pollution along with deforestation are major causes ahead of this threat. 

Illegal Sand Mining operation 

The demand for river sand has increased as the result of rapid growth in local construction industry particularly following to the end of country’s civil war. It is said that much of extraction is channelled towards Colombo and its vicinity. It is further said that traditional sand mining was replaced by mechanized dredging in order to meet the demand for the additional sand being required for reconstruction activities. According to statistics, more than 35 of the 103 rivers in Sri Lanka are subject to illicit river sand mining and that more than 50% of all sand used in the construction sector is sourced from unlawful operations. Many studies highlight the devastating impacts caused by illegal sand mining such as erosion of channel beds and banks, subsequent collapse of river bank and structures and change in channel morphology etc. Similarly, it affects the quality of the water and ecological system as well. 

As stated by an official of the Water Board, riverbed sand mining that has been going on at a rate in Kalu Ganga, Bolgoda Lake and Panadura River had caused sea water to flow into the Kalu Ganga, which the Board uses to pump water from. He further said that Sand mining or digging riverbeds or in stream mining has become a high – income trade for some organized operators in the area. They mine riverbeds with or without permits or in most cases they are found to have been acting in breach of their permits. According to the Disaster Management Centre (DMC), it says over 240,000 people have been affected in Kalutara district due to salinity of water.   

Hunting for natural water reservoirs and springs 

We see wealthy people, due to their financial affordability, buy mineral water bottle for their daily consumption whereas poor and middle class people from impoverished background vie for clean water which is of cause their essential need. This crisis can be simply solved if we adore humanity instead of profitability. Today, the clean drinking water became a profitable commodity in the Market. Many scholars predict that there will be world war in future but never for dominating oil or gold fields, but it would only be for conquering water springs and natural water reservoirs of other countries. 

Here, we should be aware of devastating impacts that bottled water caused. Many studies indicate that consumption of bottled water will lead two major impacts which are harmful to environment as well as public. Those are none other than proliferation of plastic products and exploitation of water tables. 

Proliferation of plastic products: 

When it comes to the proliferation of plastic products, the life cycle of plastic water bottle itself gives three types of costs namely economic, environmental and health costs. The economic costs for the production of plastic bottles are high with comparing to the cost of tap water since it has to cover up various costs in the line such as manufacturing, transportation, labeling, storing and disposing. The majority of plastic bottles are made of Polyethylene Terephthalate (PET) Plastic produce from crude oil. The Earth Policy Institute estimates that about one in four bottles of water crosses at least one international boarder by boat, train or truck before being consumed. Many studies say that from economic standpoint, bottled water is therefore much more expensive than tap water.  

Besides, the environmental cost is relatively much more disastrous than financial costs. As you are aware that the oil extraction and subsequent plastic production release greenhouse gas and cast toxins into the environment which is harm the habitats. Similarly, the transport emits carbon dioxide contributing climate change. It is estimated that half of the plastic bottles have been recycled where the rest end up as litter, getting dumped in landfills or water ways. Plastic wastes in water reservoirs are another important problem polluting the water and threating the creatures in the water and birds around it. According to National Geography, 5 to 14 million tons of plastic are flown into the oceans every day.
