IPA Repair system of drinking (potable) water reservoirs

The perfect quality of the drinking water must be ensured. Therefore, the regulations on hygiene and microbiological harmlessness, as defined in the W300, W347 and W270 regulations, must be strictly adhered to throughout the supply chain from the source to the water tap.

These regulations apply to the new construction, as well as to the repair and restoration of drinking water reservoirs, and equally to the planning, the execution and the nature of the repair products.

Drinking water is not the same as drinking water, the chemical composition varies considerably and thus the stress on the repair mortar. For example, drinking water with a hardness of 5 (soft water) attacks cement-bound drinking water systems due to a sparking attack caused by carbonic acid. This process is called hydrolysis. The building materials to be used must not be attacked by the drinking water, but they must not impair the quality of the drinking water.

The knowledge of the water quality is essential for the choice of the appropriate remediation method and the IPA mortar and sealing systems to be used.
