Case Study of WWTP Products Supporting Food Production

Does anyone know of any good case studies where WWTP products (recycled water, organic fertilisers) have been used to support agriculture precincts?

1. Are you looking to remove TSS  for water reuse? I may be able to assist with case studies depending on your application.

   1. I'm ​looking for a ​case study that ​shows ​integrated ​resource ​recovery from ​WWTPs to ​support ​agriculture. ​This could be ​land use, ​recycled water, ​soil amendments ​etc. No specifications at this point - just looking at high level options for a long term sewerage strategy.

3. Ivan Illich's book (now open source on line), H2O and the Waters of Forgetfulness, describes and gives references for the economics of the agricultural produce from 'night soil' use in Paris, France in the 19th Century. Apparently, the city literally exported produce. The economics were such that there was significant resistance to providing the public sewerage infrastructure which did away with the night soil.

4. In Southern Australia many Waste Water Treatment Plants (WWTP) disposed waste water to rivers and streams.  Such systems relied upon dilution and ultraviolent radiation for purification.  Such practices were leading to problems with blue-green algae and stomach complaints during periods of low flow.  Now- a-days most WWTP now dispose water and nutrients to land in these areas.  This is essentially waste water disposed to pasture in an irrigation system that is used for agriculture.  When loadings and harvesting are designed correctly, nutrients, salt and other 'criteria' are removed  during the agricultural component to provide an ecosystem that is self sustaining into the longer term and there is no need to apply fertilizer in any quantity.

5. there are lots of examples of wastewater use from crops beginning thousands of years ago to recent uses of manure  to lagooned wastewater, raw wastewater in Mexico ,  to highly processed water , e.g. in Monteray, California.  Google them. There is  a WHO Guideline for wastewater use in agriculture.

6. Are you talking about WWTP byproducts? Or WWTP solids used as soil amendments?
