Groundwater:  On the corner of the C. Fockstraat and Spoorsingel you will find one of the 210 wells in Delft where the groundwater level is measured continuously.

You find a groundwater level monitoring station underneath the square lid. This was originally installed in 1970 and since it was upgraded in 2014, it provides continuous measurements of the groundwater level. The city of Delft uses this information to know how much rainwater can safely be stored below ground. More generally, monitoring the groundwater is useful for knowing if the groundwater level is too high (which can cause problems such as damp basements and moisture damage to buildings) or too low (which can cause trees and other plants to wilt and die). In order to monitor the groundwater level, the city and the Water Board Delfland have installed 210 groundwater level stations throughout Delft.
