The end of a prolonged drought is always welcome; the sight of water once again rushing down riverbeds and filling up wells is lovely. But with the return of the water comes a few problems that, while they're less troublesome than the problems caused by drought, can be annoying. Look for these issues as the water levels rise once again to be sure you fix problems when they're still small.
Water Pressure Problems
Rainfall and runoff should recharge aquifers after a while -- but it can take a while. With the end of the drought, you may see others trying to pump more water out now that there are fewer restrictions and a bigger supply. But if they pump more out before the aquifer has a chance to fully recharge, you could continue to see your water pressure get lower and lower. You may actually have to replace the pump with one that can reach deeper water because for the time being, that's what you'll have and nothing else. Eventually the water supply issues will ease up.
The additional runoff and new supply of water entering the aquifer can kick up minerals that had been sitting on the sidelines during the drought as the water level fell more and more. Those minerals can make the water you get seem kind of brackish, or at least a lot harder. Monitor the pump for signs that it needs to be cleaned; the minerals contribute to the formation of scale, which can slow down the pump.
Continued Land Subsidence
One problem a lot of areas face when they use a lot of underground water is that the land starts to subside, or lower in elevation. Subsidence really can't be reversed, so don't expect your land to rise up now that the drought is over. However, subsidence can increase for years even when the underground water level stops dropping. For example, the city of Phoenix is currently dropping, through land subsidence, each year because of groundwater pumping that was reduced in 1980. What that means for you is that you have to continue to monitor how well the pump gets water out of the well and aquifer even after the drought ends and the aquifer recharges. The dropping land means the pump is dropping too, so it can be damaged by the change in how the land presses against it.
If you continue to have problems, call in a pump repair company like Jamison Well Drilling Inc. You may need a new pump or may need to replace certain parts to mitigate the effects you see after drought.
