Peering up at this towering structure, you might ask what exactly is Storvretens vattentorn? Let me tell you about this landmark in Botkyrka. The Storvretens vattentorn is located in Storvreten in Tumba.
Storvretens vattentorn is more than just a water tower. It is a symbol of the community. It has been a part of the landscape since 1966. The tower is made of hard concrete. It features a central pillar. Storvretens vattentorn reaches a height of 43 meters. It can hold 800 cubic meters of water. Orrje & Co were the project engineers. Karlsson & Wingesjö were the contractors.
But there is more to Storvretens vattentorn than meets the eye. It was built using construction methods of its time. However the concrete and reinforcements did not last. In recent years, damages became apparent. The Storvretens vattentorn was taken out of service for water storage. Despite this, the pumps at the base still push water to households.
Did you know Storvretens vattentorn underwent significant renovations? Botkyrka municipality invested 10 million kronor. This investment was to secure the future water supply. The renovation project addressed extensive damage to the concrete. This damage spanned from 31 to 35 meters. It also affected the roof gutter. A crucial part of the project was the interior renovation of the water tank. Damaged concrete was replaced. A new drinking water-approved coating was applied.
The renovation work required a unique scaffolding design. Cramo erected a 46-meter-high scaffolding structure. This provided access to all parts of the tower. The scaffolding was designed with a unique layout. It had six arms with straight sections. Triangular sections connected these arms. This design ensured stability at such heights.
The team of scaffolders faced challenges. They worked with safety harnesses. They used mobile cranes and construction elevators. The height and lack of platforms below 30 meters added to the complexity. Despite these challenges, the scaffolders ensured a stable and safe work environment.
During the renovations, Dipart Entreprenad performed concrete work. This included water blasting which created extra weight. Cramo reinforced the scaffolding. They used thick planks and plywood to create sealed work surfaces.
The renovations to Storvretens vattentorn highlight its importance to Botkyrka. It stands as a testament to engineering. It also shows a commitment to maintaining essential infrastructure for the community. The Storvretens vattentorn is a landmark. It will continue to serve the residents for years to come.
