Again, look at the table. Examine the saturated thickness levels between 1975 and 1990 and between 1995 and 2010. Each of these
are fifteen-year spans, but the decrease in saturated thickness is not the same. Even if the population were to stay the same over this time, why do you think the drop in thickness is not as great?
I believe that the lesser drop in thickness can be attributed to the water management practices we have in place now. We have enhanced our technology to recycle water usage and purify it after supplying it to the public.
Saturated thickness refers to the volume of water held in an aquifer that is defined by hydrogeological characteristics. The aquifer's rock contains pores filled with water, which adds to the total water volume in the aquifer. The saturated thickness decreased from 32.77m in 1975 to 22.48m in 1990, reflecting a reduction of 10.29m. Similarly, between 1995 and 2010, the thickness diminished from 25.08m to 12.27m, a decrease of 12.81m. Although the population did not change significantly from 1975 to 1990, the notable drop in saturated thickness from 1995 to 2010 could be attributed to water conservation efforts adopted by the community or natural factors such as sufficient rainfall revitalizing the aquifer and contributions from nearby water bodies like rivers, lakes, and ponds. Conservation measures include wastewater recycling and reducing water loss.
