Treated wastewater reuse is one of a number of solutions that need to be rolled out very quickly to meet the challenges of efficient water use. Conscious of their responsibilities, more and more local authorities are turning to REUSE.
Saur offers them 2 service packages: Urban Reuse and Rural Reuse.
Urban REUSE targets urban uses that currently consume precious drinking water, such as street and drain cleaning.
Urban REUSE replaces drinking water with treated water from wastewater treatment plants.
It’s described as Urban, because these projects are implemented in urban communities close to the wastewater treatment plant chosen to supply the treated wastewater.
Compared with Rural REUSE, Urban REUSE systems are simple, involving easily installed standard skid-mounted and mobile units.
Small volumes + defined areas of use = quick and easy installation

REUSE is becoming a more high-profile political issue The risk of water shortages is particularly high in local authority areas regularly affected by drought. Elected councilors must then use all the resources available to them to move towards a structured policy of sustainable water management. Communities hit by repeated water cuts will inevitably feel let down by a local authority that appears to be taking no action to deal with the problem. REUSE is one of the fastest solutions available in terms of implementation. So why wait? |
In 2023, more than 60 local authorities across France asked Saur about rolling out a REUSE program, and 90% of those requests were for Urban REUSE solutions.
This reflects their need to take action urgently, because can take as little as 8 to 10 months to set up an Urban REUSE scheme, rather than the 18 to 24 months required for Rural REUSE.
Although there were more from the south of France, Saur has received these requests from every part of the country, even those areas where there has been historically a very low risk of drought.
In fact, the requests received by Saur in 2023 covered no less than 80% of mainland France!

Specialist administrative skills are required to prepare the necessary documentation:
As an expert provider of water management services, Saur takes over management of the project for the local authority. |
Every REUSE project is unique, and requires preliminary feasibility studies to be conducted in order to identify what is feasible and to provide input for the documentation submitted to the authorities.
Saur selects those service providers best qualified to conduct these studies as part of ensuring that the documentation submitted is as comprehensive and effective as possible.
This selection process considerably reduces the risk of rejection by authorities that are not always in favor of REUSE.
The solutions proposed by Saur are:

Urban REUSE water production plant sizing Let’s take the example of 2 different authorities. The first has an estimated requirement of 15m3 per hour, and the other 30m3 per hour. You might be forgiven for thinking that the second simply requires the installation of ‘bigger’ skid-mounted unit to meet demand. Although this solution works, it's not beneficial financially! In the second case, Saur would recommend installing a storage tank in addition to the single skid-mounted unit to deliver the larger volume. Why? Because storing water costs less than installing a larger plant. The fact is that Urban REUSE plants don’t need to operate continuously, because the majority of the water they produce is used to fill drain cleaning trucks and/or street cleaning tankers. So having a minimum storage level of between 6 and 7m3 means that trucks can be filled immediately to optimize delivery rounds! |
