Temperatures in Malaysia is getting higher and higher nowadays, this result serious water shortage last year in May regarding to an article by Peak Johnson. In order to protect 100,000 students from temperature above 98 degrees Fahrenheit, the Malaysian government decided to closed more than 250 schools across the country. Water levels in reservoirs are falling rapidly and caused several states facing a water crisis which forced to implement water rationing.
Rainwater is consider an everlasting free source that can be acquired naturally. However, the climate change and the number of population is increases all over the world, with water pollution that is getting more serious, the demand for processed supply water also increases.
By using the water in a sustainable way may maintain a balance between its demand and supply. Rainwater harvesting is one of the simplest, most traditional and sustainable method to save the water and reusing it for both residential and commercial building. Rainwater that is collected can be reuse for planting water, washing toilet or the floor. This able to reduce the energy used by pumping the pressure on processed supply water which enhance the green living.
The diagram above showed the percentage of water consumption of our daily usage.
Even though the global is covering 70% of water, but there are only 2.5% that is fresh water. With the water shortage issue, we cannot forgo the fact that we should start planning and implement conserving fresh clean water. As an architecture student, I personally think that we have the responsible to help mitigate global climate change by helping conserve the water through our design in a building. By giving back the society throughout our design, rainwater harvesting and gray water usage able to reduce the usage of fresh water. Green toilet specification does also help conserve usage within the society indirectly. Therefore, we play an important role to be part of water conservation as well.
