The Hammelwarden water tower in the district of Kirchhammelwarden was built in 1930 for the Elsfleth-Brake waterworks. The 53 meter high tower with a diameter of about 11 meters rests on a 1 meter high base that protects it from the high groundwater level in the Wesermarsch. Its pile foundation consists of 96 wooden piles with a length of 14 meters. Unlike the rest of the tower, these piles are still in good condition as they are completely below the water table. The ground floor level of the tower is separated from the rest of the tower shaft by a cornice. This contains eight reinforced concrete columns, which are reinforced by crossbeams and carry the weight of the structure. The construction is covered by single-leaf exposed masonry. At a height of about 39 meters, a balcony surrounds the space for a water tank about 7 meters high with a capacity of 300 cubic meters. This cylindrical water tank was made of riveted sheet steel; the bottom of the tank had the shape of a segment of a sphere. Above the room for the water tank there is a viewing tower about 6 meters high, which carries a flagpole. In the shaft there is a wooden staircase and the risers and downpipes. It is lit by rectangular windows, while the drip tray area has round windows. The tower is now privately owned and is for sale.
