LIFE Phoenix develops innovative solutions for urban wastewater regeneration for
agricultural purposes, adapted to every kind of WWTP. A demonstrative plant has been
designed with more than 12 different technologies, considering a flexible concept. A
decision support system (DSS) shows the best solution to be implemented in each WWTP.


Pilot Plants

Flexible Pilot Plants (FPP) has been designed for both large-medium and small populations. Therefore, the project takes place in different locations.

Solutions for large-medium populations:

El Toyo WWTP (Almeria, ES)
Almonte WWTP (Huelva, ES)
Fonte Quente WWTP (Abrantes, PT)

Solutions for small populations:

El Toyo WWTP (Almeria, ES)
Talavera de la Reina WWTP (Toledo, ES)


The project also includes a replicability analysis. For this analysis, wastewater reuse in the province of Almeria will be study. This activity will not only provide information of the local incidence of wastewater reuse, but valuable data to be extrapolated to the EU. Several WWTRP will be evaluated among them El Bobar WWRTP, El Toyo WWRTP or Pulpí WWRTP to name a few.



Solutions for wastewater tertiary treatment

To develop and test flexible pilot plants based on new multibarrier
treatments for water reuse, meeting the new WWR-EU.

To minimize environmental and health risks ofreclaimed wate ruse, while ensuring its quality.

To reduce the OPEX oftertiary treatmet.


Diagnosis of current tertiary treatments

To study of the incidence of water reuse in WWTP in Almeria, regarding WWREU.

To develop a decision support system (DSS) and a sustainability tool to ensure
the adaptation to each specific case.


Fertirrigation trials.

Intelligent irrigation using reclaimed water.

To test fertilizers obtained in nutrient recovery process.


Better use of natural resources

Installation of LIFE PHOENIX technologies in a WWTP means the reduction of the
effluents thanks to the agricultural use of reclaimed water. Therefore, fresh water
consumption for irrigation would decrease, relieving stress over this natural resource.
Furthermore, nutrient recovery technologies would lead to the change of conventional
fertilizers to more sustainable options, minimizing associated contamination.

High quality reclaimed water

LIFE PHOENIX project produces reclaimed water for agricultural use, meeting the new
European Directive 2020/741. The project also aims to reduce the concentration of
contaminants of emergent concern in water, as well as microplastics. That way, LIFE
PHOENIX ensures the production of high-quality water, safe for human health and for the

Sustainable production of reclaimed water

Reduction of energy demand of tertiary treatments is guaranteed by the optimization of
technologies and by the adaptation of the solutions in each case. This would lead to the
reduction of greenhouse gases. Furthermore, the reduction of costs and resources would
ensure the replicability of the project.

Talavera de la Reina WWTP

Province: Toledo

Municipality: Talavera de la Reina

Inlet Flow: 174.000 P.E.

Other R&D Projects: Life intEXT

Talavera de la Reina WWTP is ascenario of continental climate, similarto the centre of Europe. Furthermore, the plant is currently the main location of another LIFE project, LIFE INTEXT, offering an effluent from non-conventional secondary treatments. Sinergy between those two projects will provide valuable data for the comparison of different technologies under the same conditions.

Fonte Quente WWTP

City: Abrantes

District: Santarém

Comunity: Medio Tejo

Inlet Flow: 20.000 P.E.

Other R&D Projects:

Fonte Quente WWTP treats wastewater by a conventional treatment of activated sludge. The plant is located closed to Tajo River and offers a new insight in water reuse in Portugal.

Almonte WWTP

Province: Huelva

Municipality: Almonte

Inlet Flow: 24.000 P.E.

Other R&D Projects:

Almonte WWTP is located in the surroundings of Doñana National Park. This plant make use of a conventional treatment based on activated sludge and currently it lacks water reuse. This location is perfect for encouraging reclaimed water reuse and fighting water stress in the National Park.

El Toyo WWTP

Province: Almería

Municipality: Almería

Inlet Flow: 21.100 P.E.

Other R&D Projects: Life Biosol, H2020 Incover

El Toyo WWTP treats wastewater from the East of Almeria. WW treatment is based on prolonged aeration, with a tertiary treatment of sand filters, ozonisation and chlorination. Reclaimed water is currently used in green areas and golf courts irrigation.
