4. Swamp and spring water can be made safe for domestic use through filtration and chlorination. Hypothesis

5. According to an article in Wikipedia about water supply and sanitation in Uganda, by 2010, 38% of the population in Uganda had no access to an improved water source. People rely on unsafe sources such as rivers, lakes an unprotected wells. Introduction

6. To design a water treatment system. To learn how to carry out scientific research. To learn how to collect, analyze and interpret data. To learn how to work in a group environment. Objective

7. Identification of water sources. Collection of water samples. Filtration using gravel method to remove big particles. Precipitation using Aluminium sulphate to remove tinny particles. Filtration using gravel method to remove the precipitate. Chlorination to kill the germs. Neutralisation using Sodium carbonate Methods (Methodology)

20. Spring water - Unfiltered: Had E. coli growth. Swamp water- Unfiltered: Had E. coli growth Spring water -Filtered: No growth. Swamp water- Filtered: No growth. Results

21. The unfiltered water from both the spring and swamp was unsafe especially for drinking as it contained coliforms and large particles. After filtration and chlorination, both spring and swamp water was clear and did not contain coliforms. Discussion

22. We conclude that this method was effective in cleaning swamp and spring water and could be used for water treatment for domestic use. Conclusions
