Gross pollution traps, trashracks, basins.

Our auditing work has established Optimal as leaders in this field. The technical and engineering skills and resources acquired over 30 years are now deployed into stormwater harvesting, wsud assets and waterways.

Through our auditing we identify asset condition, specification and rectification works needed to improve performance and optimise operating regimes to ensure best value. Often reasons for lack of performance are easily identified and rectification carried.

Physical auditing is complimented with catchment mapping, characterisation and pollution modelling (MUSIC).
