Building a custom part to repair a distribution pipe in Algiers
Discover the project
City of Algiers

The city council wanted to identify the weak points in its network and needed the equipment, expertise and responsiveness required to anticipate a possible burst pipe.


After studying the consequences of water leaks in the drinking water network of Algiers, the local water operator and EIE defined the customer’s requirement for repair parts. EIE designed and custom-built the products, and the city of Algiers bought in the repair stocks.


Following a major leak, the 1200 diameter distribution pipe was repaired overnight. The water supply was reinstated within 24 hours.

A hybrid connection solution for the management of PE networks

Local water authority in Dordogne

The authority installs all its new connections by electro-welding, but for resource management purposes is looking to improve the monitoring of its PE branch lines. The public works contractor also finds the existing material troublesome and difficult to adapt to different sites.  


Sainte-Lizaigne suggested the use of OmegaFlex, a hybrid connection solution: it comprises a multidiameter electrowelded clamp coupled to a GLOBALL 2038 bronze connecting valve.  


The PE network is now monitored with metal connections. Lighter and more compact, the OmegaFlex clamp also saves on logistics costs, as it can be used on various diameters of PE.
