Direct benefits information:
Pumped water is sold at the price of untreated freshwater.
Costs investment information:
Tertiary treatment plant, pumping installation and pipe transfer of treated effluent to the NWRM had a capital cost of 3.9 million euros. On this some 0.1 million euros are added for ponds, boreholes and pumps. These latter figures are to be verified.
Costs operational information:
Monitoring staff and operation supervising.
Costs maintenance information:
Maintenance of structures after occasional flooding. Renovation of infiltration capacity.Servicing of pumps.
Costs total information:
Includes ponds (shallow earth walls structures) with simple concrete inlets and outlets. Drilling of wells equipped with pumps, pipes for water transport, monitoring equipment (water levels/meters and quality probes). Staff to monitor and run the NWRM.
Information on Ecosystem improved biodiversity:
Construction of ponds has overtaken permanently part of habitats. No serious impacts expected on flora although construction works destroyed parts of flora population. Minor impacts on fauna are expected since works overtake parts of riparian habitats.
Ecosystem provisioning services:

The site taken by the NWRM is the Esousa main watercourse.
Ecosystem impact climate regulation:
Not relevant for the specific application
Information on Ecosystem impact climate regulation:
The application in its form does not affect in anyway climate change.
