Abstract: The WATINTECH project proposes a combination of concepts of sewer mining with urban run-off treatment in decentralized treatment facilities to enhance the recovery of valuable resources including water, methane (heat, energy) and value-added chemicals, either extracting or producing them from the fluxes inside a sewage pipe. It is also postulated thatthis combination improves the management of centralized wastewater infrastructures under variable weather events (such as heavy rain episodes combined with long dry periods). The impact of sewer mining and wastewater characteristics on downstream wastewater treatment plants (WWTP) will also be analysed. In an ideal scenario, besides generating the value-added products for local reuse, decentralized treatment will also impact positively on the existing centralized sewage collection and treatment facilities, an aspect rarely taken into account in the design of decentralized infrastructure. WATINTECH summons an inter-disciplinary consortium offering capabilities that cover the whole R&D value chain - from fundamental research to market uptake. The project will advance the state-of-the-art of novel technologies to achieve five main objectives in four experimental work packages (WP 1-4) employing different size laboratory and pilot-plants and one theoretical work package modelling process innovations and providing system wide optimization (WP 5). |

Implementation: WATINTECH is structured around five complementary technical work packages. ICRA is the coordinator and responsible of the management, while ACCIONA Agua and UNICT lead WP1, ICRA leads WP2 and WP3, NOVA.ID.FCT leads WP4, and DTU leads WP5. The experimental work packages (1-4) combine the use of 7 technologies and/or processes interconnected through the streams exchanged, while WP5 receives data (and knowledge) from WP 1-4 to develop the mechanistic models and build the DSS. |

Outcome/deliverables: The main goal of the project is the development of effective decentralised wastewater treatment-water recovery units that, besides locally reclaimed products, will allow a better control of wastewater infrastructures under variable weather events, easing the pressure on the centralised systems, thus expanding their asset life-time and reducing the treatment costs. To do this, we will combine fundamental research with optimization and integration of novel and existing treatment processes for decentralised water reclamation via sewer mining and urban run-off treatment and storage, with a strong focus on the water-energy nexus. The project specifically aims at providing fit-for-purpose quality reclaimed water from different wastewater streams produced within a city suburb. This will be achieved simultaneously with the energy recovery from wastewater via enhanced biogas production in anaerobic digestion. Implementation of an innovative electrochemical system for improving biogas quantity and quality will facilitate the production of several value-added chemicals, which will be dosed directly to the local sewer network to control detrimental sulphide emissions. The inclusion of constructed wetlands for urban run-off treatment and water storage will provide the overall concept with the robustness to deal with heavy rain periods and dry weather episodes, besides offering social amenity for the local community. The existing downstream WWTP will be optimized to treat wastewater with lower COD and higher pH. New mechanistic models will be developed and used for process optimization, while the integration of sewer mining with the centralised urban water system under different scenarios will be analyzed with a multi-criteria decision support system. To accomplish the main objective of the project, a set of novel and existing low-energy, low cost, low chemical and high efficiency technologies will be investigated, including their optimization with advanced modelling tools. The specific objectives are:
