CapeTalk listeners asked why building contractor Strata Civils are using a great deal of potable water to compact ground before laying concrete.
The listener says he has seen the company filling their tankers with potable water from fire hydrants which is then used to wet the surface area before compaction. The crew said it has been approved by the City of Cape Town.
Xanthea Limberg Mayco member for informal settlements, water and waste services, explains to Kieno Kammies what is going on.
The contractor is very aware of water restrictions and is only using a minimum amount of water required to achieve compaction.— Xanthea Limberg, Mayco member for informal settlements, water and waste services
In order to achieve compaction a minimum of 6-8% of moisture is required, she says.
Builders and developers need an additional water application over and above the building permits.
They are responsible for managing the water usage which is linked to a metered stand pipe monitored by the City.
They pay for every single litre used.— Xanthea Limberg, Mayco member for informal settlements, water and waste services
The contractor has also sent requests to the City for alternative water sources and the testing process is underway.
Take a listen to what builders are doing to help bring down water usage:
