There is only one readily available, accessible, and inexpensive substance that can be widely used to combat fires: water. However, in a changed climate where drought and forest fires are far more prevalent, and where commercial and residential development in vulnerable areas makes for ever more expensive property damage, available  … Read More

Water Reuse Technology

Water Reuse Technology

|

Recycling and reuse of water have been in practice since shortly after the earth was formed, using natural methods, cycles, and filters. In recent decades, technology has been incorporated to speed up the natural processes in order to meet the ever-increasing demand for clean water. Natural processes in water reclamation  … Read More

Everybody sings in the shower. At least that’s the belief that Susan van Rooyen and Moe Kekana were operating under as they developed a brilliant water-saving campaign in Cape Town, South Africa. And as it turns out, they were right.

As drought conditions became grave in late 2017 and the  … Read More

Soil Water Sensors

Soil Water Sensors

SOIL MOISTURE MONITORING CAN be useful as an irrigation management tool for both landscapes and agriculture, sometimes replacing an evapotranspiration-based (ET) approach or as a useful check on ET-based approaches since the latter tend to drift off target over time. All moisture sensors, also known as soil water sensors, measure  … Read More
