01 / INFLUENT

It arrives
carrying everything.

Industrial effluent, produced water, municipal load — raw influent is a record of everything we ask water to do.

TURBIDITY
850 NTU
BOD
420 MG/L
SOLIDS
600 MG/L
02 / TREATMENT
01Intake

Raw influent arrives — solids, grease, hydrocarbons, dissolved load.

02Screening

Coarse solids and grit are taken out before the water moves on.

03Biological treatment

Micro-organisms consume the dissolved load in the aeration basins.

04Clarification

Fines settle out; turbidity falls and the water turns clear.

05Reuse

Treated to standard — returned to irrigation, industry and the environment.

Raw influent arrives — solids, grease, hydrocarbons, dissolved load.

03 / SUSTAINABILITY

Wastewater is not
the end of the cycle.

It becomes a resource.
