To match drinking water extraction to the available supply, and thus to avoid excessive lowering of the groundwater table, the groundwater level is monitored by means of water level wells. The 300 water level wells belonging to the Hamburg Water Authority are equipped with a mechanical measurement system. Due to increasing demand, the devices need to be read with increasing frequency. Some 150 of the wells are in remote locations, making reading difficult in bad weather. At the beginning of 1987, three of the wells were fitted with an automatic measurement system. Energy for the measuring devices and for data transmission was obtained from a photovoltaic power supply manufactured by Telefunken Systemtechnik. The aim was to establish the advantages and disadvantages of using such a system. Implementation of a project of this kind requires: (i) thorough analysis of electricity consumption; (ii) wide-ranging research into data preparation and transmission (radio interface and equipment); (iii) clarification of ownership, insurance, maintenance, etc.
