Constructed Wetlands applied to the region of Curitiba and Paraná

  1. 1. CONSTRUCTED WETLANDS BEST PRACTICAL MEASURES FOR THE REGION OF CURITIBA AND PARANÁ
  2. 2. SITUATION REVIEW LACK OF PROPER SANITATION THROUGHOUT BRAZIL Sanitation in Brazil Access to disposal system No access Sanitation in Paraná Access to disposal system No access 56% 44% 54% 46%
  3. 3. TOO EXPENSIVE TRADITIONAL CENTRALIZED STRUCTURES ALTERNATIVE SOLUTIONS
  4. 4. CONSTRUCTED WETLANDS • NATURAL PROCESSES • EFFECTIVE • CHEAP
  5. 5. BUT • NOT WELL KNOWN • NOT VERY USED
  6. 6. CONSTRUCTED WETLANDS NATURAL WETLANDS OCCUR IN EVERY CONTINENT CONSTRUCTED WETLANDS ARE BUILD TO MAKE USE OF THE WATER PURIFICATION PROPERTIES FOR HUMAN NECESSITIES
  7. 7. CONSTRUCTED WETLANDS
  8. 8. OBJECTIVE • CLARIFY WHAT ARE THE BEST PRACTICAL MEASURES TO DEVELOP CONSTRUCTED WETLANDS IN THE STATE OF PARANÁ • DRAW POSSIBLE APPLICANTS FOR THIS TECHNIQUE
  9. 9. MAIN RESEARCH QUESTION “WHAT ARE BEST PRACTICAL MEASURES FOR THE USE OF CONSTRUCTED WETLANDS IN THE REGION OF CURITIBA AND PARANÁ?”
  10. 10. PROCEDURE INTERNATIONAL ARTICLES AND REPORTS ARTICLES AND REPORTS ABOUT C.W. IN PARANÁ GENERAL RECOMMENDATIONS LESSONS LEARNED BEST PRACTICAL MEASURES POSSIBLE APPLICANTS
  11. 11. PARANÁ • AREA: 199.880 km² • POPULATION: 10.444.526 • SUBTROPICAL CLIMATE • CAPITAL: CURITIBA
  12. 12. BEST PRACTICES
  13. 13. BEST PRACTICES # LOCATION USER 1 Foz do Iguaçu Secondary school 2 Campo Mourão House in rural area 3 Irati 2 houses in rural área 4 Pinhais 2 secondary schools 5 Piraquara 1 house 6 Antonina 3 houses/3 wetlands in a natural reserve 7 Morretes 1 house in a natural reserve 8 Guaraqueçaba Accomodation in a natural reserve 9 Guaraqueçaba 1 house in a protected area
  14. 14. BEST PRACTICES CARACTERISTICS • LESS AREA NEEDED: 1m² per person • NOT MUCH USE OF ELECTRICAL DEVICES • STRUCTURE: made of concrete or plastic canvas • ACTIVE INVOLVEMENT of users
  15. 15. EXOTIC PLANTS USED: Cana indicaCyperus papyrus Zantedeschia aethiopica
  16. 16. NATIVE PLANTS USED: Typha sp. Juncus sp. Heliconia sp. Cymbopogon nardus.
  17. 17. CHALLENGES AND OPPORTUNITIES • There is interest from government, ngo’s and people • But there is a lack of technical expertise • C.W. is a proper solution for nature conservation areas
  18. 18. CHALLENGES AND OPPORTUNITIES • C.W. is a proper solution for beach summerhouses, countryside cottages and farms • C.W. is also a proper solution for housing complexes in cities outskirts • Public-private partnership is a way of spreading the technique
  19. 19. CONCLUSION AND RECOMMENDATIONS Some of the developed practical measures are: • Active involvement of the users • Subsurface flow systems are recommended • Plants cited before are proven to be efficient
  20. 20. CONCLUSION AND RECOMMENDATIONS • Creative use of local resources • Make laboratorial analyses to check efficiency • Public-private partnership to popularize the technique
