Identifying the Feasibility of Canal Recharge for Indirect Potable Reuse: The Plantation Experience
Abstract:South Florida water utilities are facing some of the largest and most challenging water supply issues they have ever encountered. As a result, South Florida utilities are seeking alternative sources of water. As part of this effort, the City of Plantation and the South Florida Water Management District entered into a cooperative agreement to evaluate the feasibility of recharging the drinking water supply by discharging tertiary-treated wastewater to the East Holloway Canal (EHC). However, due to the sensitivity of the EHC, the treated effluent would be required to meet several key criteria; stringent nutrient limits (TN < 1.5 mg/L and TP <0.02 mg/L), microconstituent removal/destruction, zero toxicity impacts on aquatic organisms, and remove any hormonal effects. Two treatment process schemes using dual membrane technology were piloted for those parameters. The purpose of this paper is to share the results of this pilot project with the municipal community and review key issues associated with canal recharge, and surface waters in general, for indirect potable reuse.
