In Đà Lạt, Vietnam, a 30-month pilot supported by Partners for Water shows how smarter water management can save up to 40% on fertiliser use and reduce water consumption by 35%.
Fresh Studio® led a Dutch–Vietnamese consortium — together with Ridder, Royal Brinkman, and HollandDoor — to introduce a closed-loop drain water system with UV disinfection, helping pepper growers in Đà Lạt capture and reuse nutrient-rich drain water that would otherwise be lost.
In substrate systems, 20–30% of irrigation water typically drains away. Without collection, that water – and the nutrients it contains – leaves the production cycle. By turning drain water into a resource, farmers reduce both environmental impact and production costs.
Building on this successful pilot, Fresh Studio and consortium partners now aim to see 2 to 5 additional growers adopt the system in the coming years. As René van Rensen explains: "If the results are clear and the system proves reliable, farmers will decide for themselves."

In Vietnam's greenhouses, excess drainage water is lost unused into the ground. Fresh Studio shows how reuse cuts costs and reduces environmental impact.
