WRRF Digestion Capacity
Please identify your facility’s available capacity to accept feedstocks from offsite sources for all digesters combined. When calculating this available capacity, please take into account the average volume of wastewater solids processed at your facility and conveyed to your plant via your collection system.

co-digestion system received and processed feedstocks (other than
wastewater solids) from offsite sources.
Please indicate how organic feedstocks from offsite sources are handled upon receipt at your facility.
