Prepare for Possible Day Zero
This page provides information on:
- How Day Zero is calculated
- How to develop a Business Continuity Plan
The idea is to avoid a possible Day Zero BUT this will require the concerted effort of government, businesses and residents working together to reduce water consumption.
For the City of Cape Town, possible Day Zero refers to the day when most of the water supply system is switched off. Residents will need to collect 25 litres of water per person per day from points of distribution (PODs) located across the City. The City is working towards ensuring that strategic economic nodes are still provided with municipal water and that businesses located outside these areas are able to access water.
A possible Day Zero will be determined differently within each municipality and when the day is reached slightly different processes will be instituted.
As is clear below, Day Zero is not a static date - it is dependent on numerous factors, such as:
- Temperatures and wind speed which influence evaporation rates;
- New supply volumes and timing on when they come online;
- Consumption of the available water.
The City of Cape Town has developed a dashboard to inform residents of when that day is calculated to be, and how far the City is in securing various alternative water supply sources.
Developing a Business Continuity Plan
The Western Cape Government is developing its Water Business Continuity Plan to ensure the delivery of essential WCG services can continue even if the supply of municipal water becomes severely constrained.
Below are some points to consider when developing a business continuity plan for your organisation:
To provide businesses with guidance on creating their own water operational plan (supports improved water use practices under water rationing circumstances) and a business continuity plan, A Basic Business Continuity Planning Guide has been developed. This presentation may also assist in the process.
