NCPA professional staff traveled to Mesa, Ariz., on Nov. 20 to conduct outreach and education during the Arizona Water Association’s 2019 FOG & Pretreatment Workshop.
On the second day of the workshop, Director of Outreach and Technical Education Claude Goguen, P.E., LEED AP, spoke to an audience of approximately 60 wastewater professional technicians, regulatory inspectors, managers and policymakers on the occurrence of MIC in precast concrete gravity grease interceptors.
Goguen spent time during the workshop to address the attendees’ experiences and challenges associated with MIC in precast concrete gravity grease interceptors and septic tanks. These productive discussions provided Goguen an opportunity to help shape a more informed understanding of MIC occurrences.
Additionally, Goguen connected with Owner of Olson Precast during the conference – a precast manufacturer and NPCA producer member in attendance. The pair discussed ways in which Olson Precast attempts to prevent MIC in precast gravity grease interceptors, including experimentation with polymer concrete.
Goguen concluded that more research is needed to identify ways to protect precast tanks from the effects of acidic conditions and MIC. Furthermore, he highlighted the need for increased focus on attending similar FOG and wastewater related events. He provided a list of large shows and associations to monitor:
