waste sector desk
The City of Cape Town’s Water and Sanitation Department has released the Water Outlook 2018 Report. The summary contains details on the current water system status including the latest water system figures, recent water consumption trends, as well as the key risks to maintaining water levels.
Recent water consumption rates continue to exceed the City’s target of 450 million litres of water per day, and current dam levels stand at 24.3%. Water levels have dropped at a rate of 0.4% during the past week. Day Zero has been shifted to the 9th July 2018 and should this day occur, the water reticulation network will be turned off to 75% of the City and residents will have to collect water from "points of distribution". Water saving efforts must improve and current consumption rates must decrease in order for Day Zero to be averted.
The summary contains the City’s newly proposed measures for 2018 under consideration for implementation to maintain water supplies. These include:
- Introducing punitive tariffs from 1st February 2018 to target water abusers
- Further implementation of demand management devices and flow restrictors
- Severe pressure management that may disrupt water supply
The summary emphasizes the need for the agricultural sector to reduce their current water consumption rates, with particular focus on those not adhering to the existing restrictions. For agriculture, dam water releases will need to be curtailed to compensate for the sector having already used two-thirds of the allocated usage for the entire year.
In addition, the City has provided an interactive Dam Level Model which can be used to assess dam levels against different percentage usage by each consumer category, as well as through input of augmentation project figures in Ml/day with corresponding dates. Users can interact with the highlighted green cells to model a projected scenario and monitor resultant dam levels.
