Spain: INNOQUA pilot site in Quart

Quart is located in the southeast part of Spain close to the city of Girona, in the Catalonia region. The village is served by a municipal wastewater treatment plant (WWTP) which also collects the wastewater from Palol d’ Onyar, another nearby village.


The INNOQUA system treats the raw wastewater from the villages of Quart and Palol d’ Onyar. The pilot site works in parallel to the conventional WWTP in order to test various experimental conditions for research and validation purposes.

Design Capacity: 1.5 m3/day (10 population equivalent)

Source of Wastewater: Municipal

Specific Scientific Research Objectives:
To assess the potential for the INNOQUA technology to be implemented as a decentralised system treating municipal wastewater, the site is testing performance under different operating conditions.

In Spain the INNOQUA system consists of a lumbrifilter and a daphniafilter installed on the outflow from a septic tank. Afterwards, the collected effluent can be further treated with a UV step. Moreover, alternatively to the daphniafilter, the BSP system can be operated as a different technological option.
