2 DEMANDS ON POTABLE WATER TANKS Smooth surfaceClean abilityResistance of lining against potable water(at chlorination up to 1 ppm)Absolute tightnessNo ground water infiltration through concrete wall (at buried tanks)Potable Water Tanks – generalHydroclick systemInstallationReferencesLimitationsApprovalsCurrently used systemsTilesCoatingsConcrete without further treatmentThermoplastic liners
3 POTABLE WATER TANKS - GENERAL Problem: Coating of potable water tanksPotable Water Tanks – generalHydroclick systemInstallationReferencesLimitationsApprovalsLimited service life Contamination of potable water by detached particles
4 POTABLE WATER TANKS - GENERAL Hydroclick systemInstallationReferencesLimitationsApprovalsProblems caused by solvent water:Service life ?Maintenance ?Repair ?
5 ADVANTAGES OF SYSTEM Product approval acc. to KTW (for potable water) Raw material approval DVGW-W270 (for pot. water)No deposits on the tank wallEasy to clean – high pressure resistance (130bar)Good resistance against chlorination up to 3 ppm(0,5 ppm free chlorine resp. 0,3 ppm ClO2)Long service life (PE-pipes 50 years)Fast installation / shorter construction times!Ventilation gap avoids creation of aggressive condensatesPotable Water Tanks – generalHydroclick systemInstallationReferencesLimitationsApprovals
