Presentation about a research over the constructed wetlands for waste water treatment in the state of Paraná and the lessons taken from it.

1. CONSTRUCTED
WETLANDS
BEST PRACTICAL MEASURES FOR THE
REGION OF CURITIBA AND PARANÁ

2. SITUATION REVIEW

4. CONSTRUCTED
WETLANDS
• NATURAL
PROCESSES
• EFFECTIVE
• CHEAP

5. BUT
• NOT WELL KNOWN
• NOT VERY USED

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. CONSTRUCTED WETLANDS

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. MAIN RESEARCH QUESTION
“WHAT ARE BEST PRACTICAL
MEASURES FOR THE USE OF
CONSTRUCTED WETLANDS IN THE
REGION OF CURITIBA AND PARANÁ?”

• SUBTROPICAL CLIMATE
• CAPITAL: CURITIBA

# 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. 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. EXOTIC PLANTS USED:
Cana indicaCyperus papyrus Zantedeschia
aethiopica

16. NATIVE PLANTS USED:
Typha sp. Juncus sp. Heliconia sp. Cymbopogon
nardus.

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. 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. 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. CONCLUSION AND
RECOMMENDATIONS
• Creative use of local resources
• Make laboratorial analyses to check
efficiency
• Public-private partnership to popularize the
technique
