Leaks in distribution systems are costly. Added to the direct cost of the lost water that cannot be sold are the financial and environmental costs of finding, treating and storing more water to compensate for the losses. This problem affects rich and poor cities alike. Many utilities do not know the exact extent of the water loss in their system.

In Tokyo, Taipei and Seoul a solution was found to reduce the leaks significantly by using stainless flexible service lines. A new Team Stainless leaflet explains the system and the results in a nutshell.

  1. With proper polyurea coatings applications, old pipe can be rehabilitated and waterproofed without expensive pipe replacement.  Also, engineered microbiological engineered sewer systems can distributed almost potable water for subsurface discharge and the same system can clean up already contaminated water sources such as lakes, lagoons, retention ponds, rivers, etc. Call me if you want to know more, J.

    1. Dear Jennifer, Thank you for your post about polyurea coatings, however perhaps you have misunderstood our concept. Our objective evidence shows >95% of water supply leaks occur in the joints in the service lines and also that polymer-based materials decay and leak in much shorter times that their declared operational lives. The stainless solution addresses these undesirable features of the traditional systems and brings additional benefits in terms seismic resilience and a maintenance free solution. Therefore the life-cycle cost is massively (>>30%) lower that traditional solutions. Furthermore the environmental footprint of stainless steels is much lower on a service line installation level comparison than all other polymer-based solutions. I believe it is important to think in terms of solutions that are revolutionary and long term rather than things aligned to our traditional 'fit and fix' culture that we have been 'brought up' with.

      I would be more than happy to discuss further.

      Best regards.
