Treating drinking water is a very responsible task making extremely high demands of the hygiene as defined in the DVGW guidelines. Concrete surfaces need to be smooth, free of blowholes and even. Without any joints, edges or through-tie holes. In contrast, the ceilings have rough surfaces so that condensation can drip down immediately.
The SBB formwork system offers crucial benefits for the construction of drinking water systems: through-tie-free tanks that are precisely circular and monolithic with no zones without through-flow. The entire ring wall is free of seams and work joints. This round construction not only offers hygienic benefits but is also the most structurally stable and economic solution.
