Reports are pegging a total of four months left of usable water in the drought-stricken Cape declared a disaster area.

Kieno Kammies, broadcasting live from Spier Wine Estate on World Water Day talks to City of Cape Town Xanthea Limberg, Mayco member for informal settlements, water and waste services, about how these figures are calculated.

Usable dam levels sits at 18.6%. That equates to about 103 days and that does take us into water.

Limberg explains this is calculated based on average current consumption and make provision for evaporation levels.

Even if we experience rainfall in winter, we will still be maintaining water restrictions throughout to ensure that we minimise the impact come next summer.

She says way beyond average rainfall is needed through winter but is not optimistic this will occur due to climate patterns.

We believe that even during the winter rainfall period our dams might not fill up beyond the 62% mark which is why we are implementing emergency water supply schemes.

These include further drilling down of boreholes into the Table Mountain Group Aquifer and erecting the small scale desalination plant.

Those two things will happen before 30 June, and will already start yielding a couple million litres of water per day.

There is a second tier of emergency measures planned for emergency supply schemes if there is below average rainfall through winter.

She says the City is recommending a household monthly usage of 50 kilolitres per month, preferably 20 kilolitres.
