Sand dams: They’re expensive, complicated to build, and nine times out of ten simply do not work. Or so says Erik Nissen-Petersen, experienced rainwater harvesting practitioner and author of ‘Rainwater Catchment Systems for Domestic Supply: Design, Construction and Implementation.’
In a video interview with The Water Channel, Nissen-Petersen argues that sand dams are a waste of time and money and asks the question: “Why not just go for sub-surface dams?”
In this interview, Simon Maddrell, Excellent Development’s Executive Director, answers this question and explains why Nissen-Peterson has got it wrong when it comes to sand dams.
