In 2001, IRIDRA managed the design of a constructed wetlands system for the wine-producing firm “Tenuta dell’Ornellaia”, Leghorn, Italy. The system consists of vertical flow constructed wetlands (SFS-v) as a first stage followed by a second SFS-h stage with recirculation to the first stage and then by a single FWS. It treats wastewater from the firm, which allows water to be reused for irrigation

An educational wetland of 30 PE treating the sanitary wastewater of a toilet building.

Two constructed wetlands at Warsco Genk treat the run-off from 1 ha pavement and the cleaning water from a washing street for temporary units.

2-stage Vertical Flow Constructed Wetland for the treatment of raw domestic sewage (French system) for 1360 people-equivalent adapted to the local resources and climate with UV tertiary treatment.

"Zero Emission" would be the general goal for sustainability. Especially for industrial production. Tertiary treatment with constructed wetlands may be a proper solution for closing the loop. The new treatment wetland at Changshu Advanced Materials Industrial Park, Haiyu Town, Jiangsu Province, China, is not only reclaiming water. It is a stepping stone for humans searching nature and for endangered species within a widely industrialized zone. Designed as a beautiful park it provides recreational functions and serves as buffer stripe between chemical industries and urban areas.

The wetland visitor center with its terraces on the roof and near the water level reveals a stunning new perspective. Intersted visitors will be given looks inside of the wetland when entering the exhibition on the first floor. Accomplished with a water laboratory and wetland control room the Changshu AMIP wetland center is a perfect place for training and dissemination of environmental solutions.

 

Grenoble – urban park Ouagadougou: a 1 ha urban park with reed bed filters and surface flow wetlands collecting and treating stormwater runoff from the roofs of buildings and from adjacent roads in order to meet irrigation needs of the park and to reduce discharge of stormwater into the municipal sewer system. This project was the laureate of the NOVATECH 2013 international conference of sustainable urban drainage award http://novatech.graie.org/a_present_laureats.php

  • Adapted „French system“ for a nursing home, Hogar de Ancianos Sta. Ana y San Joaquín y Asociación Ayuda Me Perú
  • All treated wastewater is reused for irrigation of agricultural used area
  • The 2 staged wetland system treats the domestic effluent of 55 residents and employees
  • The pre-treatment is carried out on the surface of an planted, vertical flowed gravel bed wetland with 2 charging points, used alternately (2 and 2 days)
  • The post-treatment is carried out in an planted vertical flowed sand bed wetland with 4 divisions to maintain always the biologically activity in all parts of the wetland
