Sewer Line Network
In the Mackenzie District, there are presently four public sewerage schemes: Fairlie, Lake Tekapo, Twizel and Burkes Pass. There are 2,774 properties connected to these four schemes. The other properties in the district dispose of their wastewater by other means most via their own septic tank system.
Final disposal of effluent is by way of soakage trenches, basins to land or irrigation to land. These systems minimise environmental pollution and protect public health and safety by safeguarding hygiene and preventing the spread of communicable diseases.
