The smart misting system at the Prima Deshecha Landfill (PDL) is designed to aid in controlling landfill odors as part of our comprehensive odor management program. The project consists of a solar-powered misting system that is attached to a permanent litter fence with fogging emitters, a water filtration system, odor neutralization capability, a solar array with back-up batteries, a pump shelter, an electric motor pump, an equipment shed, a gravel pad, and a wind-driven directional switch. Our smart misting system at PDL is synced with an onsite weather station to manage odor based on wind direction is an innovative and practical solution to an environmental issue. The system uses sensors to monitor wind direction and adjust the misting output accordingly. In addition, the system helps conserve water by only using the necessary amount of water to effectively manage odors. This project improved the odor control measures onsite and positively impacted the neighboring community by minimizing the effect of daily landfilling operations.
