CONSTRUCTION OF AN AQUAPONICS SYSTEM AT THE DEPARTMENT OF CIVIL ENGINEERING, FEDERAL POLYTECHNIC OFFA

This project focuses on the construction of an aquaponics system at the Department of Civil Engineering, Federal Polytechnic Offa, as a sustainable approach to integrated food production and water resource management. Aquaponics combines aquaculture (fish farming) and hydroponics (soilless plant cultivation) in a symbiotic environment where fish waste serves as nutrients for plants, while plants help purify and recirculate the water. The system was designed and constructed using locally available materials to ensure cost-effectiveness and ease of maintenance. Key components include fish tanks, grow beds, a water circulation system, and filtration units. Engineering principles such as fluid flow, structural stability, and efficient water use were applied throughout the design and implementation process. The constructed system was evaluated based on water quality parameters, plant growth rate, and fish survival rate. Results indicate that the system is capable of supporting sustainable food production with minimal water wastage and environmental impact. The project demonstrates the practical application of civil engineering techniques in promoting sustainable agriculture and offers a viable model for small-scale and institutional use.
