What is the wastewater sewerage service charge?

Properties connected to the public sewerage network are assessed a wastewater charge equal to 50% of the volumetric water consumption value.

How does registering multiple residential units on one meter reduce the bill?

NWC multiplies the cubic meter capacity of each tariff bracket by the number of registered residential units, expanding lower-tier allowances and preventing premature escalation into expensive higher tiers.
