For example, at the international airport in Delhi, over 300 wells have been built to collect rain water for recharging groundwater/aquifers. As water consumption at the airport is extremely high (about 4.5 mld), practises of RWH and water recycling help airport authorities in meeting the demand, and thus reduce dependence on the city’s already overburdened water supply agency.
For example, a sample of water with a pH value of 12 will have a higher conductivity than a sample that has a pH value of 7. Table 3.9.3 shows the pH chart and Figure 3.9.7 illustrates the pH values already mentioned both numerically and in relation to everyday substances.

For example, if it is expected that the well will be deepened later, then the production casing must be wide enough to allow the passage of a drill bit later on. It is also instrumental in preventing blow-outs, allowing the formation to be "sealed" from the top should dangerous pressure levels be reached.
