Water as a Service

Only pay for the water you use

Water as a Service (WaaS) is an innovative water subscription service that provides a comprehensive solution for customized water treatment and management. Under the WaaS model, customers pay for the amount of water treated rather than investing in water treatment equipment and infrastructure themselves. This approach offers several benefits and ensures optimum water management.

At Veolia Water Technologies, we will work closely with you to improve your water management while reducing capital expenditure. WaaS offers a convenient and cost-effective way for businesses that need a reliable source of process water for their production processes while reducing costs and promoting sustainable water management.

By opting for WaaS, you gain peace of mind through always having access to high-quality water, coupled with preventive maintenance and the reduction of operating risks, via a monthly or annual subscription that guarantees your financial control. 

You only pay for the amount of water treated and so this pay-as-you-go model allows for better financial flexibility and can be tailored to your specific needs.

What's more, our solutions are flexible and can adapt to your changing needs. WaaS means you can concentrate on your core business, while being assured of a reliable, high-quality water source.

Feed water that complies with French and European requirements

Veolia had been working with this customer since 2009 to meet its feed water needs using Sirion™ Maxi and a Sirion™ Mega osmosis plant. This equipment was made available via two Water as a Service contracts, enabling the customer to focus on their core business while maintaining a reliable, high-quality water source. The contract included preventive and curative maintenance, replacement of consumables and spare parts and the supply of five mixed beds at the osmosis outlet and two on the loop.

Ultrapure water requirement

The customer needed a complete solution for up to 100 liters of ultrapure water of 18.2 MΩ.cm from pre-purified water. This is provided for the customer as part of a Water as a Service package.

Water treatment for cooling towers

A French yeast production site wanted to meet its new technical and regulatory challenges, while controlling the risk of legionella in its cooling towers. Thanks to Water as a Service, the customer was able to reduce its chemical usage and improve the quality of its waste, to comply with new regulations and generate significant OPEX savings.
