Abstract:

St. Petersburg, Florida, committed itself to total recycling of its wastewater with zero discharge to its surrounding bays. They plan to accomplish that goal through land disposal techniques. The techniques are not entirely new, however, the findings of viral studies have indicated that commonly used effluent irrigation and landspreading systems are inadequate. Increased treatment is required prior to disposal to obtain virus-free conditions. This new system will incorporate the suggested changes. As an alternative to advanced treatment facilities, Spray irrigation and landspreading of effluent and sludge, respectively, is still a viable alternative.
