Cool. I wish I could

Can we take a look at that too! Look how clean it is now that the sludge has settled out. Later this treated effluent will be sprayed onto Whakarewarewa Forest.

No mate. Those ponds store the treated effluent. Each day it’s sprayed on the forest and passes through wetlands and mother earth before entering waterways again. Were those swimming pools back there?

Waipa Stream

Any phosphorus that was still in the treated effluent is held in these volcanic soils. Cool! This looks great!
