Joburg saves millions of litres of water using low-flush cisterns

Joburg saves millions of litres of water using low-flush cisterns: With the objective of saving about 580-million litres of water a year through its low-flush cistern toilet system project, utility company Joburg Water says the project can also save the city about R3.5-million a year. “Households currently use 29% of their water for flushing. The project is technologically driven and can reduce usage by . . . up to 7 ℓ of water per flush, compared with the previous system that uses 12 ℓ of water per flush,” says Joburg Water communications and marketing manager Isaac Dhludhlu.
