There are times when ebb and flood benches are used solely to collect run-off water from a crop that has drip irrigation. At some greenhouse operations, the base system is small, and the ownership may be unsure if it is fiscally responsible to recirculate. The water collected is minimal and an argument could be made if it makes financial sense to reintroduce the lesser amount of water into the system or drain it to waste. There are many considerations when deciding whether or not to recirculate water. Is this a seasonal issue? Is there a lot of fertilizer being wasted? Is water expensive in your area? Will the government mandate zero waste?
The team at Zwart can help you navigate these questions and more to decide if it makes sense now or if it will in the future and prepare a greenhouse system that can be adapted to Zero runoff systems.
