Stormwater treatment and reuse techniques : a review

The elementary importance of improved management of stormwater for urban centres, irrigation, industrial, domestic, and stock uses across the world cannot be overemphasised. This paper presents a review of the available stormwater treatment and reuse techniques and introduces a new technology known as ‘Green Gully’ that collects, purifies and reuses stormwater throughout an automated network system. A comparative study of available treatment measures with respect to advantages, disadvantages and pollutant trapping efficiency is presented and discussed. This paper also highlights the current stormwater reuse techniques to reduce the water crisis. Conclusions based on a comparative study of stormwater treatment measures and reuse techniques are presented, which will be useful for stormwater researchers, planners and stormwater management in general.
