What are the basic information that I need to prepare before building a new water or wastewater treatment system?

Clients need to prepare information as below :

a. Capacity required

b. Industrial Effluent Characteristic Study (IECS) Report

c. Land area plot drawing for the new treatment plant

d. Current production process flow diagram

Remember, there are no two similar factories in wastewater treatment plants, despite producing the same end products. Each functional, sustainable treatment plant is a unique case/ design on its own.
