Climate change leads to more extreme weather. Urban areas experience more floods due to heavy rainfalls and a decreased buffer capacity (due to an increase of hardened surfaces). Runoff water is contaminated with heavy metals, mineral oils, etc. which makes it difficult to infiltrate it or reuse it when buffered. At the same time, droughts cause an increased scarcity of water sources, damage to foundations of buildings, salinization, forest fires and problems for agriculture, flora and fauna.
Developed by Ecological Water Management
EWM filters, buffers and stores runoff water, and infiltrates it if necessary. Runoff water contaminated with heavy metals, mineral oils, etc. is treated and stored underground, making it available for reuse in all kinds of applications (extinguishing water for the fire-departments, irrigation, process water, etc.), while saving money on drinking water. EWM increases ground water levels and prevents desiccation and salinization during dry periods, by safely infiltrating the treated water.
See more information about this level and the TRL and SRL levels.
The innovation is a combination of underground buffering preceded by several ecological treatment steps. Contaminated runoff water is collected through a drainage system, after which it is treated up to standards of Dutch legislation (as elaborated in the ‘infiltration decision soil protection’). Treatment is done through a mix of granulated shells and the ‘AA Mineral Mix’. The granulated shells also have a buffering effect. After treatment, the water is stored in an underground buffer, which contains an Airlift system in order to have permanent flow. As a next step, before reuse, the water quality is improved through a bioreactor and the AA vitaliser. If necessary, large volumes of treated water can be infiltrated through the DSI system.

Added value
The combination of water buffering with water treatment, making urban areas more resilient for both heavy rainfall as well as droughts. By applying the EWM concept, cities do not only increase their buffer capacity, but also harvest water that can be reused for various purposes. As such, drinking water and related costs can be saved. The treated and collected water can be used: 1) By fire-departments (making them less dependent on the drinking water network or low quality surface water which has negative influence on the equipment); 2) As irrigation water for (artificial) sportfields; 3) As irrigation water in agri- or horticulture or parks and gardens; 4) If required and possible as drinking water (depending on the legislative environment), and only when constantly monitored. Alternatively, the treated and collected water can be reused to safely infiltrate into the ground to: 1) increase ground water levels in case of droughts (hence prevent damage to dikes and foundations of buildings as well as problems for flora and fauna); 2) Prevent salinization through the creation of aquifers.

The main components of the system have been tested separately, and an initial integration exercise has been conducted.
