The existing sludge feed system in Complex A at the WRRF pumps sludge from the sludge storage tanks (SSTs) to Dewatering Complex II (CII Dewatering), where ultimately the sludge is dewatered and then incinerated, and also pumps sludge from the SSTs across the street to the Biosolids Dryer Facility (BDF), where the sludge is dewatered and ultimately dried and utilized as a class A fertilizer. The piping and pumping systems that feed the Dewatering Complex II and the BDF are approximately 40 years old and unable to meet the operational demand of the WRRF solids system. The pumps and piping in many cases of operations are too large, causing GLWA Operations to try and restrict the flow to avoid over feeding the BDF or CII Dewatering. This mechanical restriction is causing excessive wear on system pipin...
