[ Solutions listing ](/en/expertise/applications " Solutions listing") **Wastewater is continuously growing in volume due to the increase in domestic and industrial water consumption. The high cost of water transportation, as well as new environmental issues such as increasing water scarcity, make the topic of water reuse and wastewater recycling increasingly important.** [CONTACT US TO FIND OUT HOW WE CAN HELP](https://www.veoliawatertechnologies.com/en/contact-web2lead) What is water reuse? Water reuse is the use of treated wastewater for beneficial purposes other than its initial use, such as for **cooling systems, boilers,**[ ](/en/applications/process-water "Process water")[**process water**](https://www.veoliawatertechnologies.com/en/expertise/applications/process-water)**, irrigation, cleaning or** [**groundwater**](/en/applications/groundwater-treatment "Groundwater treatment") **recharge.** Who needs water reuse? Domestic populations, as well as industrial transformation processes, consume large amounts of water resources on a daily basis and produce large quantities of wastewater. Reuse is a **sustainable solution to optimize and mitigate water consumption, and tackle local water scarcity issues.** Regulations regarding the reuse of water are strict and vary from one country to another. Applications may include: - Cooling of facilities. - Water for boilers. - Water for industrial processing. - Agricultural irrigation. - Watering of green spaces and golf courses. - Storing and reusing [groundwater](https://www.veoliawatertechnologies.com/en/applications/groundwater-treatment), and salt intrusion barriers in coastal municipalities. - Public fountains and street cleaning. What are the benefits of water reuse? Reusing water is now an important issue for all sectors and all regions wanting to **optimize their consumption**, lower their costs and safeguard their operations from the growing scarcity of water. Reusing water in their industrial processes also helps companies **save money and minimize waste processing costs**. Wastewater treatment plants can now be converted into biorefineries capable of producing energy as well as valuable by-products such as biopolymers. With our treatment technologies, municipalities are able to produce: - Reusable water. - Fertilizers. - Nutrients. - Thermal energy. Reusing water offers significant advantages in terms of how much water is drawn from the natural environment, and in terms of conventional water supply costs. Reuse is therefore a proven weapon for **combating water shortage**. It provides a constant and reliable water source at the places where such sources are necessary, and makes it possible to prioritize allocating freshwater resources to meeting [drinking water](https://www.veoliawatertechnologies.com/en/applications/drinking-water) needs. ## How Veolia is committed to helping its clients increase their water reuse ## In most industries, such as [microelectronics](/en/core-markets/electronics-and-photovoltaics "Electronics & Photovoltaics "), [pulp and paper,](/en/core-markets/pulp-paper "Pulp & Paper ") [power](/en/core-markets/power "Power"), [food and beverage](/en/core-markets/food-beverage "Food and Beverage ") and [oil and gas](/en/core-markets/oil-gas-downstream "Downstream Oil & Gas"), the high volumes of water used during the overall manufacturing process represent a significant expense. Drawing upon its worldwide experience in industrial water cycle management, we have developed standard solutions for water recycling and reuse **to support all industries.** ![Brochure Reuse - img](/sites/g/files/dvc3601/files/styles/default/public/image/2022/03/Capture%20d%E2%80%99e%CC%81cran%202022-03-15%20a%CC%80%2010.56.37.png.webp?itok=fX-_6xdI) [**Brochure: sustainable water management for Recycling & Reuse**](https://www.rcp.veoliawatertechnologies.com/sites/g/files/dvc2471/files/document/2022/03/recycling_reuse_brochure_2014.pdf) ## Supporting clients to implement sustainable water reuse solutions ![](/sites/g/files/dvc3601/files/styles/show_case_card/public/image/2022/03/Capture%20d%E2%80%99e%CC%81cran%202022-03-15%20a%CC%80%2011.05.28.png.webp?itok=jRxyXqTu) AUSTRALIA A gold mine will operate in a sustainable way. The Fosterville Gold Mine, located in Australia, experienced a significant increase in gold production due to exploration in 2018. The client wanted to implement a **water treatment plant to treat the mine water to reuse it within their process water circuit.** Veolia Water Technologies designed and supplied a **reverse osmosis solution**, providing **high-quality treated water for reuse**, enhancing the **mine’s sustainability** and allowing the client to continue meeting its license conditions.

This challenging project reuses up to 60% to 70% of effluent for agricultural purposes. One of the largest plants in Europe treats wastewater “not only according to environmental directives, but also to have a circular use of the water,” explains Francesca Pizza, process manager at the Nosedo [wastewater treatment plant.](/en/applications/municipal-wastewater "Municipal wastewater treatment") We help our client **optimize the whole wastewater system** by integrating the operation of the sewer system and the wastewater treatment plant, **saving energy and chemical consumption and increasing its hydraulic capacity.** [Learn more](/en/case-studies/building-nosedo-wwtp-systems-resilience-hubgrade-digital-solution) ## Reusing wastewater: a vital issue Wastewater is continuously growing in volume due to the increase in domestic and industrial water consumption. The high cost of water transportation, as well as new environmental issues, make the topic of water reuse and wastewater recycling increasingly important. This wastewater is polluted by organic compounds, bacteria and other harmful elements, and yet it now constitutes as a **fully recoverable resource** thanks to the progress of recycling techniques. We have developed a wide range of innovative solutions to **improve the environmental impact of water consumption.** #### Steam condensate recovery and return **Condensate is a high-purity, high-heat content water**, and even the smallest quantity recovered is often economically justifiable which is very appreciated in municipal and industrial applications alike. Reusing condensate minimizes the need for additional, cold makeup water that would require treatment and heating, which would incur additional costs. By returning condensate to the boiler feed tank, the need for boiler blowdown is reduced which **saves money by reducing the energy** **lost** from the boiler during the blowdown process. #### Condensate is a potentially **valuable resource** as it is high-purity, contains virtually no total dissolved solids and has high heat content. **The purity and absence of dissolved solids make condensate ideal for use as boiler feedwater.** [CONTACT AN EXPERT](https://www.veoliawatertechnologies.com/en/contact) ![Hands on crops.

It can also be used when wastewater is treated and used again in the process. - **Water reuse** is the use of treated wastewater for beneficial purposes other than its initial use, such as cooling systems, boilers, process water, irrigation, cleaning or [groundwater](/en/applications/groundwater-treatment "Groundwater treatment") recharge. ### What factors affect the choice of water treatment technologies for recycling water? Four key factors influence the choice of treatment line for recycling water within industry: 1. The **quality** of the wastewater to be treated. 2. The **application** for which the recycled water will be used. 3. The **configuration** of the industrial site. 4. Local **legislative requirements**. ### What are the water quality requirements for reusing water within industry? Quality requirements vary for different applications and industries, but some broad generalizations may be made for **industrial water, cooling water,** [**process water**](/en/applications/process-water "Process water") **and boiler feed water.** ## Technical resources *Find related content below.
