The Broad Run Water Reclamation Facility (BRWRF) Interim Biosolids Project will expand the capacity of the solids treatment process at BRWRF through the addition of two (2) additional anaerobic digesters. The work will include the new tanks, supporting appurtenances, separate biogas storage, and improvements to the existing polymer feed facility within BRWRF's thickening and dewatering building. Minor modifications to the primary scum pit and primary sludge piping are also included.
