Offenbach am Main water tower

from Wikipedia, the free encyclopedia
Twin elevated water tanks

The Offenbach am Main water tower is a twin water tower . Thanks to its location on the 132-meter-high Bieberer Berg, the two elevated tanks ensure sufficient water pressure in the 420-kilometer-long drinking water system of Energieversorgung Offenbach , which supplies the cities of Offenbach am Main , Dietzenbach and Mainhausen with drinking water.

Construction of the water tower began in 1966. In 1968 the two elevated tanks with a height of around 45 meters were completed and put into operation . Each of the containers has a maximum water level of 33 meters and holds a maximum of 7,500 cubic meters of water. This results in a total volume of 15 million liters of drinking water. Due to the location of the water tower at the highest point in the city, the drinking water is supplied without pumps solely through the hydrostatic pressure resulting from gravity .

The water tower is replenished via pumping stations by the water supply association for the city and district of Offenbach, which extracts fresh water from 115 groundwater wells and six waterworks in the region. Since the purpose of water supply association can deliver about 400 cubic meters per hour, the consumption at peak hours, but is more than 600 cubic meters per hour, the water tower at the same time serves as a surge tank in the water supply system of the power supply Offenbach.

The annual consumption of fresh water in the supply area was 8.1 million cubic meters in 2005 and decreased to an annual consumption of 7.4 million cubic meters by 2011. According to the operator, the line losses amount to 2.7 percent in relation to the total amount of water fed in.

Redevelopment

The water tower was renovated from 2013 for 3.6 million euros. For this purpose, an elevated tank was emptied at the end of 2013 and the interior was newly coated and renovated by April 2014. Since the water consumption is higher in the summer months and both chambers are required with the full volume of 15,000 cubic meters, the refurbishment of the second elevated tank was carried out after the dry period by spring 2015.
