PortFolio 3: Water: Quality and Quantity
The world’s population is increasing therefore the quality and quantity of water has become more and more of a concern and there are three ways on ensuring that high-quality water can still be made available for future generations. The three ways are water recycling, desalination and conservation. Water recycling is about using well-treated waste water and an example is to use them for toilet flushing rather than using fresh water to flush toilets. Desalination is a process where salt is being removed from water. Though it is a very expensive process, engineers are doing research and developments to make it cheaper because it is still welcomed by places where there is a shortage of water. The last method is conservation and it basically means to save and reduce water usage. This method of conservation involves many parties, the residents, the farmers and industries so that high-quality water will still be made available for future generations. Residents are educated in water-saving habits and they can save water by changing their old 6 gallon toilets to 1.6 gallon toilets and it will greatly help the problem of insufficient water being faced in the world. Farmers are encouraged to help by using drip irrigation techniques and soil moisture sensor where water is provided to the soil by drip method only when the soil needs it. Industries help by installing water-saving devices so that the water usage is at its minimum. There are many challenges that engineers are working on, to come up with cheaper processes, more gadgets and ways for people on earth to apply to help improve the quality and quantity of water. In conclusion, the amount of water on earth is fixed and the world’s population is increasing, there are three ways where engineers have introduced to ensure that high-quality water can last for future generations. Everyone plays a role in conserving water and engineers will have to carry on working on ways to have sufficient water for the world.

Indeed the world population is increasing; we could not neglect the quality and qualities of water only when we are facing shortage of water resource. In Darryl portfolio, he has mentioned three ways in which water can be recycled. His content for this portfolio is rather informative; he had clearly explained the three different types of methods which we are employing now. Darryl has pointed out that it is the individual responsibility to conserve water which I totally agreed on. Conserving water is not the government effort; it is also not the engineering effort to come up with cheap desalination whereas it is the effort of everyone.
Looking at the increasing population trend that the world is facing now, water shortage is a major problem. Water shortage does occur as human population increases because water supply does not increase.
I agree with Darryl's opinion on the three methods of providing qualitative and quantitative water.
They are all significant in aiding to provide fresh water. Recycling of water and conservation of water can cut down unnecessary use of fresh water, whereas desalination can help supply more fresh water.
In my point of view, I support conservation of water to the greatest extent as that greatly cut down the unnecessary use of water. At certain times, we cannot supply water at the same rate we use them, thus by conserving water, we can then have enough supply of water for distribution.
