Wastewater and nutrients reuse
Treated wastewater is an often-overlooked resource that can play a key role in making agriculture more resilient to water scarcity and climate stress. By safely recovering water and nutrients from domestic or farm-related wastewater, targeted treatment and reuse systems enable local reuse of nutrient rich water irrigation water, reducing pressure on freshwater resources and external fertilizer inputs.
Within GEORGIA, innovative nature-based and circular wastewater solutions demonstrate how water and nutrients can be reused close to where they are generated. These approaches support circular water management, improve soil fertility, and strengthen drought resilience at farm level—while complying with water quality and safety requirements.

VertECO® green wall wastewater treatment for on-site reuse in market gardening
A nature-based “green wall” system that treats domestic wastewater on-site and makes it available for safe agricultural reuse. It helps small farms and market gardens reduce freshwater demand while recovering nutrients for irrigation.
Nature-based sludge-drying reed bed for circular wastewater and biowaste management
A nature-based system that dewaters and stabilises sewage sludge using planted reed beds. It turns sludge into a nutrient-rich material that can support circular soil management and reduce reliance on synthetic fertilisers.
Sludge–biochar soil amendment for improved soil quality and crop resilience
This solution combines stabilised sewage sludge with biochar to produce a high-quality compost-like soil amendment. It improves soil structure, water-holding capacity and crop resilience, particularly in perennial systems such as orchards.
Treated municipal wastewater reuse for irrigation
A farm-level reuse approach that supplies irrigation water from treated municipal wastewater, typically with on-site storage and a disinfection step (e.g., UV). It increases irrigation reliability in water-scarce regions and can reduce pressure on freshwater resources.
