The two pie charts illustrate the distribution of residential water usage across five categories in the years 1988 and 2008.
Overall, the bathroom accounted for the highest proportion of water use in both years, while the garden consistently represented the smallest share. There were only minor changes in most categories over the 20-year period.
In 1988, the bathroom consumed the largest portion of water at 32%, followed by washing at 25%. Toilets and kitchens accounted for 20% and 15% respectively, whereas only 8% of residential water was used for gardening.
By 2008, the bathroom remained the dominant category, slightly increasing to 34%. The percentage of water used for washing dropped to 22%, and toilet usage decreased marginally to 18%. In contrast, kitchen water usage rose to 20%, making it equal to toilet consumption. Water use for the garden experienced a slight decline, falling to just 6%.
In conclusion, the bathroom consistently remained the primary consumer of water in households, while minor fluctuations occurred in the other categories over time.
