4. Conclusion

In conclusion, Singapore's water quality is not as bad as compared to other countries, and it can be further improved!

In the past, Singapore depended on other neighbouring countries (Malaysia etc.) for usable water but now, we are developing much more in the fields of science and technology! Thus, we have come up with various ways to get more water that are safe to use/drink; Local catchments, NEWater and Desalination plants.

This is indeed good as we are now independent!

Based on the results collected (surveys, interviews and water-testing), we can say that on average, Singapore's nitrate level is 20, ammonium nitrate level is 22 and lastly, its calcium level is 45.

This may seem good to you but in actual fact, it is not!

Other than that, I believe that new inventions or methods can be tried out too. Based on our recommendations, we plan to make Singapore a country with a higher water quality rate by modifying the desalination method, such that graphene filters are used, in this way, the water collected will be more purified and its efficiency is better than the original by two to three magnitudes. The modification of the NEWater method will also benefit the people because, as you all know, NEWater uses recycled water. The water needs to be further purified by ultra violet rays (disinfection). Thus, with the new method, water calibers will be used, along with the help of Arduinos to control the system and make it more effective. 

We, as a team, believe that with all these methods used, Singapore's water quality will definitely rise in the coming years, but who knows? This will also contribute to Singapore's golden age (Development in science and technology). The water quality also affects the quality of living in Singapore, as well as its economy!
