A procurement plan is already underway for a number of augmentation schemes, including desalination, water reuse and groundwater extraction.

“Over the last 11 weeks, under the leadership of the Chief Resilience Officer, and with the support of the Water Resilience Task Team created by Council, a portfolio response has been developed and supported by professional consultants, some of whom have experience in responding to droughts in other parts of the world, including Australia and California,” said De Lille.

Various programmes, each with associated initiatives, have been established over the emergency phase, which will run until the end of June 2018, and tactical phases, which will run from July next year onwards. These initiatives build on the drought response initiatives since late 2015, which include pressure reduction, increasing restrictions, and heightened enforcement.

The city’s intent is to drive down collective usage to 500 Mℓ/day as well as to ensure that there is always at least 500 Mℓ/day of water in production.

The plan involves ways to augment the system using a number of technologies and sources by up to the target 500 Mℓ/day over the months ahead. This is a significant increase compared with the relatively small schemes that were being planned up until May this year.

Water augmentation schemes

The new solutions to augment Cape Town’s water supplies are based on a Request for Information/Ideas (RFI) released by the city.

Over 100 submissions were received, proposing solutions including desalination at various scales, inclusive of container solutions, barges and ships, water reuse technology at various scales, aquifer and borehole options, engineering and infrastructure options, and water demand management options, among others.

A variety of technologies have been chosen to augment the system and an extensive procurement plan is now in place with procurement having commenced.

The below figures per technology reflect schemes at full production. Commissioning dates vary according to staging of procurement and complexities related to installation and site preparation. Installations are contingent on relevant licensing approvals.

The procurement and commissioning of multiple new augmentation schemes in rapid time will be one the largest and most complex expenditure programmes in the City of Cape Town’s history.

To ensure success, approximately 80 new staff (inclusive of contractors and permanent staff) will be hired in the coming weeks to assist with delivering the full extent of the envisaged projects.

A command hub will be established in the Civic Centre to allow for co-location of the full team.
