Converting Lagoon into Freshwater Wetland

Dear Friends,

We are living in lagoon area and the freshwater availability is reducing. I am working with Community Mobilization organization for water resources. We are thinking about converting lagoon into freshwater wetland like "Porirua Lagoon" project.

Your views are invited to guide us on this innovative process. Is this a feasible way to get freshwater? Is it proven that it may have some adverse environmental effects (Please share some case study published etc) ?

Whom should we contact if we wish to convert the lagoon to wetland? Which agencies can do a feasibility study for such project?

1. Yes , with process of bio and pyto-remediation , the lagoon (s) /  areas can esaily be converted into construted wetlands. All the contaminants will be taken by various aquatic plants . The case study is attached 

2. Try contacting Dr Chris Tanner, NIWA, Hamilton NZ as he is one of the noted researchers and practitioners in wetlands

3. Just contact me oliver.kopsch@dwc-water.com
   

4. Contact for zero carbon no filters and no chemicals desalination mechanism. rosjonesenvedu@hotmail.com

5. Things to consider:

   -is the lagoon area home to protected species and/or is it an important stop over for migratory birds

   -conversion to freshwater would mean blocking off salt water recharge. This essentially would prevent flushing of the lagoon and could cause a build up of silt and contaminants. High levels of pollutants and need to dregde the silt to maintain capacity pose new problems

   -is the lagoon an important economic source for various users

   -A SWOT analysis of freshwater coonversion of lagoon vs an alternative (e.g. desalination plant) should be carried out

   1. attempt to convert lagoon in to storage for domestic water use will bring plenty of changes. First and most important - what is the source of fresh water to replenish lagoon water. Is it adequate enough to create potential difference to create fresh water floating zone, since entire salinity would not go off. Rest of the issue need attention subsequently.
