Figure 8 shows the percentage change of maximum daily rainfall. The majority of the positive changes are reported in the last six months, while the majority of the negative maximum rainfall changes are reported in the first few months. This trend signals that the use of RWH can be useful, especially during the first few months of the year. However, to effectively utilize the harvested rainwater, the system should be capable of capturing enough rainfall from the rainy days of the later
months of the year.
