The pie charts illustrate the proportion of water used in different purposes by local individuals in 1988 and 2008.
Overall, the two charts reveal a dramatic shift away from usage of water for bathroom toward kitchen. Additionally, kitchen, which was previously the smallest segment, emerged as the leading by amount of water using by the end of the period. In contrast, toilet was the only sector to suffer a reduction in amount of water used, while water usage on washing clothes remained virtually unchanged.
Looking at 1988 in detail, bathroom made up the largest proportion of water used, standing at 25%. This was followed by washing clothes and garden, which accounted for 22% and 20% respectively. Meanwhile, toilet represented a smaller usage at 18%, whereas kitchen constituted the lowest slice of the pie at just 15%.
By 2008, significant shifts were recorded in the distribution. Most notably, the share for bathroom, which was previously dominant, fell slightly to 29%. Conversely, kitchen experienced a substantial increase, leaping from 15% in 1988 to 30% to become the new primary sector. Meanwhile proportion of water used in toilet saw its decrease to 15%, and washing clothes figure slipped slightly to 19%. Finally, amount of water used for garden dropped dramatically by 12% to 20% in 2008.
