Collecting & cleaning wastewater

Saur mission industry 2
Collecting, cleaning and recycling wastewater, an imperative and an opportunity

Globally, human society discharges no less than 80% of our wastewater into the environment without recollecting or treating it. In developed countries the percentage is lower, often around 10%, while in developing countries it can be as high as 95%. Not only does this contribute to contamination of natural water and the environment, it also represents a waste of valuable resources that can be repurposed, for example, for fertilizers, soil conditioners or even fuel. At Saur, we view wastewater collection, treatment and reuse as both an imperative and an opportunity.

From plant efficiency to discharge quality

We subject all of the wastewater treatment plants we construct and manage for clients to a rigorous program of self-monitoring. This program covers everything from overall plant operation - including energy efficiency and emissions - to discharge quality. Our constant aim is to ensure that all metrics comply with the imperatives imposed by our Quality, Safety and Environment policy. Our teams have access to specialist techniques and a broad range of specialist pumping and waste removal vehicles.

Preventive maintenance

Operating a wastewater treatment plant includes extensive inspection and maintenance services, aimed at ensuring the integrity of wastewater collection pipeline systems and preventing leakage. In maintaining pipeline systems, we take a preventative approach based on regular inspection and testing, backed up by scheduled remediation and repair programs. Our resources and teams are available 24/7 to provide an immediate response to emergencies anywhere in the systems we operate. We also use video inspection and leakage tests throughout our pipeline systems, including branch connections and inspection points.

Many treatment methods

We are constantly seeking to improve existing (waste)water treatment options and have developed many of the different processes in use around the world today (check our Water Engineering division to learn more). These contribute to a more sustainable world in many different ways, for example:

  • Reduced volumes of residual treatment sludge

  • Optimize energy and reagent consumption

  • Reduced plant size

  • Elimination of micropollutants, such as pesticides or drug residues

  • Repurposing of treated water

  • Protection of water resources
