Until the 1820s, all that Niedernberg had at its disposal for water was seven windlass wells. These were only converted to pumped wells in 1834. Until the municipality decided to have the wells deepened in 1859, dry summers often led to water shortages. However, when the work to channel the Main began in 1928, the groundwater rose so far up that the wellwater began to go foul. The intention to ensure a mutual water supply with the neighbouring municipalities was never realized owing to the outbreak of the Second World War. When in 1954 the first cases of typhus came to light and the health office, after doing tests, had to shut twelve of the thirteen drinking-water wells down, and also at the same time, privately built supply facilities were affected, something needed to be done quickly. The same year, building contracts were arranged. Until 1958, pipes were being laid and houses connected. The watertower's height of 44 m was necessary given that local conditions, as in the neighbouring municipalities, precluded using high-level tanks to get the needed water pressure. The Niedernberg watertower has a diameter throughout its height of 10 m. The two watertanks, made of watertight reinforced concrete, hold 250 000 L and provide a water pressure of 3.5 at in the waterpipe network. The watertower's paint job in brown, yellow and grey came during the refurbishment in 1982. Since then, its appearance has changed only with the installation of a variety of cellular antennae.
