ENERGY: wind, solar,.. and WATER
by Marcel Paalman PhD MSc

Roadshow WiCE On Friday 14 December the Dutch and Flamish watersector presented various projects and initiatives related to the role of water in the energy transition. It is clear that in this context water can play an important role and strengthen the possibilities of wind and solar energy. Estimated is that heat from surface water, waste water and drinking water could be...

California – water management challenge
by Kees Roest PhD BSc

Nate Engle write in a blog about a visit of Botswana government study tour to California about water management. In Orange County they take treated sewer water, purify it to near distilled water quality, and then recharge it back into the groundwater basin for future extraction and treatment as drinking water. California also uses water from the Colorado River Basin…...

Drought 2018: maize crop benefits from treated wastewater
Drought 2018: maize crop benefits from treated wastewater
by Ruud Bartholomeus PhD MSc

The 2018 drought affected agriculture heavily, especially in the sandy Eastern part of the Netherlands where freshwater supply by rivers is not possible. Treated wastewater is increasingly being considered as freshwater source for irrigation. Our experimental site in Haaksbergen clearly showed the benefits for crop yields of subsurface irrigation using treated wastewater. Additionally, the drought provides insight in the ‘worst...

Groundwater recharge with wastewater: the soil as natural filter
by Ruud Bartholomeus PhD MSc

At the Penn State’s Living Filter Site (https://www.fondriest.com/news/penn-states-living-filter-site-of-study-into-emerging-contaminants.htm) the land application of wastewater effluent is investigated. Land application may be beneficial for recharging groundwater aquifers, but it may also avoid direct discharge of pollutants to the surface waters. The site allows to investigate many relevant topics, like the potential pollution of aquifers with 'contaminants of emerging concern'. In this paper…...

Resource efficiency
We have about 12 years left
by Kees Roest PhD BSc

That is the alarming message of the IPCC. To avoid some of the most devastating impacts of climate change, the world must slash carbon emissions by 45% by 2030, and completely decarbonize by 2050. Andrew Winston wrote an interesting article about the steps that some of the world's leading companies take and he remains optimistic that companies will be doing…...
