Water Wheel May/June 2025: Sludge Management

Abstract

New strategy sets out sustainable path for sludge management in SA Feature As part of a broader project on sludge management, a research strategy has been developed to guide research in this field over the next decade. Article by Sue Matthews. In the November/December 2024 issue of The Water Wheel, Matthew Hattingh put an entertaining nautical spin on a topic many of us prefer to steer well clear of (See ly/3YxRwUW). Sludge – the word itself tends to conjure up an unappealing image and visceral response, and in this case referred to both sewage sludge from wastewater treatment works (WWTW) and faecal sludge from pit latrines and other forms of non-sewered sanitation (NSS). The article covered an online workshop titled “Sludge Management in South Africa: What’s Possible, What’s New and What’s Next?” , co-hosted in August by the Water Research Commission (WRC) and Isle Utilities, which was conducting a WRC-funded project aimed at analysing trends, innovations and advances in sludge management practices and technologies in low-and middleincome countries.
