Independently, the h2o utility company and ONAS now Use a modernized billing method, streamlining income selection. ONAS’s IT process has become upgraded to include Laptop-centered Evaluation of serious-time information, which makes it doable to control wastewater move remotely and much more proficiently.
- While sixty p.c of homes eliminate wastewater via a general public sewerage method, Considerably of this goes on the drainage procedure with only ten p.c of the wastewater handled.
