New free book on water-related SDGs: On Target for People and Planet

IWMI scientists urge realistic targets, wise investment choices and sustainable water resources development while building resilient ecosystems

Water-related Sustainable Development Goals need to be appropriate to the local context or poor people and the environment will lose out, according to a new publication by the International Water Management Institute (IWMI).

Key challenges include setting realistic targets, making the right development choices, and promoting sustainable water resources development in a way that values healthy ecosystems, the scientific research organization says in On Target for People and Planet: Setting and Achieving Water-Related Sustainable Development Goals. ...

Guest Post: What are Sand Dams?

What are Sand Dams? 

Sand Dams are the most cost-effective form of rainwater harvesting and provide communities with a clean, local and reliable source of water – even during periods of drought.

Sand Dams store up to 20 million litres of water and provide a year-round supply for up to 1,000 people – with virtually zero operation and maintenance costs.  Sand Dams store water under sand, protecting it from contamination and evaporation – cleaner water that lasts longer.

"Simplicity is the ultimate form of sophistication": a data-driven model for forecasting manganese concentrations in subtropical reservoirs

The latest article in our Journal Author Guest Post series comes from Edoardo Bertone, co-author of Bertone, E., Stewart R.A., Zhang, H., O’Halloran, K. (2014). Intelligent data mining of vertical  profiler  readings  to  predict  manganese  concentrations  in  water  reservoirs. Journal of Water Supply: Research and Technology—AQUA 63(7)

Continuously monitoring and managing manganese (Mn) concentrations in drinking water supply reservoirs are paramount for water suppliers, as high concentrations create discoloration of potable water supplied to the customers. Traditional Mn management approaches typically involve manual sampling and laboratory testing of raw water from supply reservoirs on a regular basis (typically weekly) and then treatment decisions are made based on the soluble Mn level exceeding an allowable threshold level. Often Mn testing is conducted all year, but in the sub­‐tropical regions, such as the Gold Coast, Australia, where Advancetown Lake is located, high Mn
concentrations only occur for a brief period during the winter circulation process. ...

Guest Post: The Performance of Wastewater Treatment (Stabilization) Pond Systems Globally

This Guest Post comes from Matthew E. Verbyla University of South Florida verbylam@mail.usf.edu 

Wastewater treatment ponds are perhaps the most widely used treatment technologies in the world, especially for smaller cities and towns. There are reportedly more than 8,000 wastewater treatment pond systems in the United States (Figure 1). France has approximately 2,500 systems (Mara and Pearson 1998), Colombia has at least 100 (Figure 2) and they are the most commonly-used technology in Mexico, the Dominican Republic and Brazil—in fact, wastewater treatment ponds comprise nearly half of all wastewater treatment facilities in Latin America (Noyola et al. 2012). Wastewater treatment pond system effluent is often reused by farmers for irrigation (Mara 2003). ...

Interview: Professor Marcos von Sperling

Ahead of the WaterWiki Event at the World Water Congress, we caught up with author Professor Marcos von Sperling whose books form the foundation of one of our most popular pages, the Free eBook resource. We asked Marcos to tell us a little bit about himself and why he chose to make his books available for free on the WaterWiki. ...

Guest Post: Recent Publication on Virus Removal in Wastewater Treatment Ponds

This Guest Post comes from Matthew E. Verbyla University of South Florida verbylam@mail.usf.edu

At the University of South Florida, we have been studying pathogen removal in wastewater treatment pond systems in Bolivia for the past couple years (Verbyla et al. 2013a, b). Our most recent publication (Symonds et al. 2014) examines the removal of viruses in these systems. The efficiency of virus removal in wastewater treatment ponds is still poorly understood and the overall consensus has changed throughout the years. ...
