Emergency cleaner water increasingly strong shadowing the island of Batam. Raw water throughout the dam is getting shrinking. Not only small dams such as Nongsa and Sei Harapan, Dam Sei Ladi and Mukakuning which has a relatively larger size is also the raw water more worrying.
Adhya Tirta Batam (ATB) as clean water management in Batam Island has even started to rotate water supply (water rationing) for customers who get water supply from Dam Sei Ladi following water rationing which has already been applied for ATB customers who get water supply from Dam Sei Harapan.
The rotation of the water supply is subject to ATB to extend the duration of raw water. Moreover, the service area of ??Dam Sei Ladi and Sei Harapan has not been reached by Duriangkang Dam pipeline so that the raw water in both dams must really be used sparingly enough until the dry season passes.
During this Dam Duriangkang indeed become the mainstay of raw water in Batam Island. Indonesia's largest estuar Dam is the mainstay of raw water for 70 percent of ATB's customers in Batam Island. Dam is flowing ATB customers who live in Batam Center, Sei Heat, to Bengkong and Tanjung Sengkuang.
Ideally Dam Duriangkang able to accommodate 78.56 million m3 of raw water. Initially the dam is predicted to last up to eight months ahead without rain, but the condition of Dam Duriangkang not as good as expected. Pendangkalan make dam is predicted to fall faster if the rain does not go down with the intensity as expected.
Every month ATB utilizes Dam Duriangkang raw water up to 5,500,000 m3, whereas since early 2015 the raw water in Dam Duriangkang has never increased due to long drought due to El Nino. Moreover, based on ATB Data, entering 2015 Dam Duriangkang raw water has never been at zero level or maximum level of raw water. Since January 2015, Dam Duriangkang has shrunk 0.16 meters and continues to shrink to the level of 2.22 meters.
When calculated, throughout mid-January to August 2015 ATB has been using the raw water Dam Duriangkang about 44 million m3. The calculations are based on a rough calculation of raw water consumption every month as much as 5,500,000 m3 times the month we have passed through 2015.
If we consider the raw water Dam Duriangkang only reduced due to ATB routine utilization, it means that currently the raw water Dam Duriangkang still left about 34.56 million m3. Suppose there is shrinkage of raw water due to drought or evaporation, so raw water in Dam Duriangkang live 30.000.000 m3.
Means 30 million m3 divided by raw water routine utilized ATB every month as much as 5.500.000 m3. Based on these calculations, Dam Duriangkang only lasted about five months. ATB even predicts the Dam can only survive until January 25, 2016 if continue to be used as it is today without adequate rain.
CHANGE WATER USAGE PATTERNThe raw water dam is increasingly critical, requiring ATB to do water rationing. Since September 1, 2015 customers in the Tiban and Sekupang areas have begun to experience the rotation of water supply due to the depleting raw water reserves. Similarly with the region of Baloi and Tanjung Uma who began to feel the rationing as of 17 September 2015.
Though very forced, the company that got the 25 years concession from the Batam Authority (BP Batam) must do the rotation of the water supply because Dam Sei Harapan is expected to only survive until the end of October 2015 and Dam Sei Ladi until January 2015 if it continues to be used like this without rain intensity which can add raw water.
Long dry drought is actually an opportunity for ATB customers to be more motivated to use more water sparingly. During this time the use of water in the city of Batam somewhat wasteful. Everyone generally uses 160 liters of water per day, well above the ideal reference for clean water needs of the Ministry of Public Works (PU) which is only 60 liters / person / day.
Emergency clean water can actually be used as a starting point for the people of Batam to appreciate the water. Especially as we know Batam Island does not have natural water resources and only rely on rain water as a source of raw water. Batam does not have natural springs that come from the mountain, Batam is also not ditanugrahi river with abundant water like in other cities in Indonesia.
Perhaps it is time for the people of Batam to change the pattern of water usage. If previously wasted water just because it felt the water will continue to flow as long as we can pay the bill, from now on let's scrape away the mindset like that.
From now on let's use water as needed. If the vehicle is not too dirty, do not wash it every day. Neither when cleaning the yard. Should we clean the yard by sweeping and mopping, not by watering a lot of water using a hose.
Emergency water is actually also a test for the people of Batam. The rotation of the water supply can illustrate the extent of tolerance of every citizen in Batam Island. Do they think of neighbors, relatives or relatives, by tolerating and using water as necessary, or even selfishly competing for clean water by hoarding?
The flow of water can not be regulated as well as the flow of electrical energy. The closest customers of the Water Treatment Plant (IPA) with a not so high location will definitely get a more reliable supply compared to customers located further and higher than IPA.
ATB has anticipated water rationing for clean water to be more evenly distributed to customers by three day method, one day off, and two days on, one day off. But the program again also needs support tolerance from the nearest customers from IPA. The more efficient and the fewer upstream customers hold the water, downstream customers will enjoy the cleaner water faster.

IMPORTANT WATER BUT NOT CLOSED
As we know, water is the source of life. No human can live without water. Once the importance of water for life, to the extent that the originator of the Republic of Indonesia state water explicitly in the 1945 Constitution.
The first thing astronauts are looking for when exploring another planet to be explored as an alternative human residence other than Planet Earth is water. For when there is water, it means that there is life on the planet. Conversely, if not found water, a little difficult to explore the planet as a human residence.
Water is very crucial and irreplaceable by any substance to sustain life of living beings. Although water is so important, until now there has not been a single human technology capable of producing a substance that can substitute the function of water.
Perhaps the problem of the existence of water is also one of the reasons why Batam Island was almost uninhabited. That is also the reason why the ancient times Tanjung Pinang, Lingga, Karimun and other areas in Riau Islands Province more developed than Batam. The area is even mahsyur up to the neighboring states because there is the Riau-Lingga Sultanate.
Batam began to develop as the central government through the Batam Authority (now BP Batam) developed the area as an industrial area. When the Batam Authority enters, some infrastructure such as electricity, roads, ports, airports, also water began to be developed.
Water management is even treated a bit special. As the island of Batam grows and the Batam Authority feels unable to manage it alone, the government agency then appoints private managers to manage clean water in Batam Island for 25 years since 1995.
The existence of water in industrial areas is absolute. Without water, the entire infrastructure built will be in vain. Moreover, to build a variety of infrastructure also definitely require water. What would be the construction of a road without water, how could the airport be built without using a drop of water.
JAGA AIR FOR BATAM FUTUREOnce the importance of water for the life of us all, therefore let us keep together the availability of water in Batam. Let's keep the water for Batam's future sustainability. Moreover Batam is an industrial city that definitely needs water for all business activities.
Currently Batam Island has five active dams used as a source of raw water Dam Sei Harapan, Sei Ladi, Nongsa, Mukakuning, and Duriangkang. The next few years will be added with Dam Tembesi with a capacity of 600 liters / sec.
When the sixth normal reservoir is enough to meet the needs of clean water Batam Island, but we do not forget Batam is the city with the highest growth rate in Indonesia. In 2014, the growth rate of Batam City reached eight percent.
If population growth continues to increase along with the addition of clean water, the addition of raw water from Dam Tembesi will not have much effect. Less than five years, BP Batam as the holder of clean water management regulator should again think about additional raw water for clean water is always enough in this island.
Therefore, before the emergency clean water actually occurs. Let's change the pattern of water usage becomes more efficient. If not now when else, when there is no water nak what kite? Ah, Salam Kompasiana! (*)
