Bulk Water Savings
Bulk reduction of leakage can save tens of millions of liters of drinking water per utility, per day. With water resources dwindling, bulk reduction of leakage mitigates stress within the water balance. This reduces the urgency for developing new potable water sources. Where intermittent water supply (IWS) is an issue, bulk reduction of leakage can also contribute to an increase in the supply time. Overall, water utilities can save tens of megawatt hours of fossil energy daily simply through bulk leakage reduction which reduces the water utility’s greenhouse gas footprint.
Until TALR, there has been no commercialized means for bulk reduction of leakage in urban distribution networks. To deal with detectable leaks, the “find & fix” method is normally used. Although effective for maintaining leakage levels, it’s not efficient for bulk reduction of leakage. Alternatively, mains could be replaced or renewed which is both expensive and intrusive for urban life.
Curapipe’s patented Trenchless Automated Leakage Repair
TALR) technology cures leaks on a large scale
It is trenchless (no dig) which ensures low disruption of environment and urban life
It enables automated detection, sealing and permanent curing of leaks
It is a low-cost alternative for pipe replacement/renewal
It provides for rapid bulk reduction of leakage
Traditional “find &fix” leak repair methods require digging up streets and sidewalks, which disrupts vehicular and pedestrian traffic and impacts urban life in general. Our TALR solution has a very low level of environmental and social disruption. Since it is trenchless, no digging is required. With TALR, traffic delays, disruption of urban life, additional pollution, degradation of the pavements and road surfaces, and additional water loss are minimized from a few days or even weeks to a few hours.
Compared to pipeline replacement or renewal, TALR is highly cost effective. Current trenchless renewal / replacement technologies (CIPP, HDD, sliplining, pipe bursting and relining) incur high direct costs of hundreds of dollars per meter.
Not only is the cost of TALR substantially lower, repairs of the cracks and leaks are designed to last for the remaining life of the water mains. This means that water distribution mains and pipes that are still serviceable, do not need to be replaced or renewed..

Most urban distribution networks suffer from leakage which in some cases can be as high as 25%-50% of the total supplied water. Furthermore, a non-proportional amount of energy is wasted due to leaks. This is caused by pumping additional flow levels through the water distribution network to compensate for the losses, which results in high levels of friction within the pipes. Bulk reduction of leakage can contribute significantly to energy savings..
