Networks

Mastery Through Knowledge

Where are our networks?


On the continent of Europe, an estimate of only 20-30% of drinkable water networks are correctly mapped. Only those produced recently have been geolocalized during their production. For the rest, the data is often approximate and relies on outdated maps or simply human memory.

This lack of precision can generate huge costs for water services, notably multiple excavations that take place before finding the right location of a pipeline needing replacement or repair, or even breaks in networks and construction delays, due to construction interventions or action taken on other underground networks. 

What condition are our networks in?

Renewal operations are dictated by town planning (population increases in a zone, new areas to serve), but also by the state of existing infrastructure.

In France, the cost to renew a single kilometer of piping is between 150 and 250,000 euros, not including subscriber networks. Therefore, management must have reliable information on hand in order to be able to efficiently plan these maintenance and renewal operations.

Precisely identifying which networks are at most immediate risk for deterioration allows for reducing extremely costly repair interventions, reduces the rate of lost water in networks, and curbs the cost of drinkable water to the public. 

Operators admit that a large part of renewal operations could be more relevant, provided that they have access to this vital information: what condition is the network in?
