AWWA ACE69018

This powerpoint presentation begins by presenting a brief overview of a 285-acre sprayirrigation facility that will be decommissioned for treatmentof municipal wastewater in June 2008. New wastewater pump station was constructed, andMOA allows identification of alternative uses of site such asreuse and reclamation, land application, andtreatment of water treatment plant waste streams. Wrenn Road is located less than 5 miles fromnew 20 mgd D.E. Benton WTP. Phased construction at WTP changespotential uses for Wrenn Road. Wrenn Road spray irrigation evaluationapproach is presented, along with waste stream characterization findings, an agronomic evaluation that focused onsedimentation blowdown and DAF solids, and alternative crop required to accommodateapplication of residuals. Four residuals management alternatives wereevaluated and included the following: sedimentation in lagoons withdredging every 1.5 years; spray irrigation of rawsedimentation blowdown; pre-settling in gravitythickener; and, pre-settling in gravitythickener and dewateringwith belt filter press. Includes tables.
