The products passing this preliminary test, then were subjected to further analysis and evaluation. The attached shows the bid price as well as the evaluated cost per tonne of dry solids processed based on performance and price evaluation of those products which met the performance criteria and specifications in the quotation terms of reference.

The Interim Functional Lead of Water and Wastewater concurs with the recommendations made.
