It doesn't sound like it to me.
You said you have lots of parcels of land. What is the requirement for groundwater? How much groundwater is required for this? I see you have some statistics in your package here that talk about the effluent water being 1,000 litres per minute, and then potentially up to 3,000 to 10,000 litres per minute.
What is the amount of groundwater you require? I just wonder how many other parcels of land you can get that are like this one, close to estuaries.
