groundbreaking project. In coordination with the Rädlinger Primus Line engineering team and the city’s engineers, the concept of the rapid response kit was realised – a unique solution.
People in the southeastern United States are used to disaster situations, especially during hurricane season. In order to maintain the water supply in such cases, Rädlinger Primus Line delivered the first two “Pipeline Rapid Response Kits” (PRRK) to Fort Lauderdale in July 2019. The two 12-metre/40-foot containers – one for drinking water and one for wastewater – hold two or three reels of rolled up Primus Liners and customised flange adapters of various sizes, at least two of each type.
These PRRKs are the fallback strategy for catastrophic situations such as hurricanes or floods, which is reassuring for those responsible for dealing with major pipeline breaks in Fort Lauderdale.
The PRRKs allow the city’s emergency response crew to bypass pipe breaks in almost inaccessible locations. Customised adapters for different pipe sizes (DN 800 to DN 1500, corresponding to sizes of 30 to 54 inches) and flexible DN 500/20-inch Primus Liners with a single length of 426 metres/ 1,400 feet per reel serve as temporary bypasses. For example, three DN 500/20-inch Primus Liners can be combined to keep up the water supply of a broken DN 1200/48-inch pipe in emergency situations and can be run at pressures of up to 16 bar/230 psi.
In some situations, opening the damaged line at two easily accessible points, rather than trying to repair it directly at the site of incident under extreme time pressure, may be the decisive factor.
In order to be optimally prepared for such catastrophic

situations with the PRRKs, the Fort Lauderdale emergency response crew spent two days training in the use and application of the Primus Liners and their adapters. Everything they need is packed in the two containers, which can be easily transported to the affected area. In addition, the entire kit can be reused for the next emergency situation.
