Will you “Repair” your manholes via chemical grout (internal or external) or seals (mechanical, elastomeric, cementitious)? Perhaps you will require manhole “Renewal” via coatings (sprayed, pumped, troweled) or liners (poured-in-place, cured-in-place)? Then again, there’s always the option of conventional open cut excavation and “Replacement”. The “R” that you select will depend on your site-specific situation and needs.

On-line registration for WEF’s Residuals and Biosolids Specialty Conference is now open. The conference will be held at the Sacramento Convention Center in Sacramento, CA from May 22-25, 2011. The theme of the conference is “Adapting Residuals Management to a Changing Climate.” Cooperating Organizations include: California Water Environment Association, California Association of Sanitation Agencies, Air & Waste Management Association, and U.S. Composting Council.
EPA has released an interim report, Evaluation of Combined Heat and Power Technologies for Wastewater Facilities, which serves as a planning-level tool for wastewater professionals and provides an examination of commonly used and emerging combined heat and power (CHP) technologies for converting anaerobic digester gas to electrical power and process heat. The report was developed by Columbus Water Works, under an assistance agreement awarded by EPA in support of their Columbus Biosolids Flow-Through Thermophilic Treatment (CBFT3) National Demonstration Project. It provides detailed technical information about existing technologies for producing heat and power from biogas including: internal combustion engines, gas turbines, microturbines, and fuel cells as well as other beneficial uses for digester gas. The report includes detailed process descriptions and performance and cost data. It also addresses factors such as infrastructure requirements, digester gas treatment, and operational issues. The interim report includes four in-depth facility case studies from across the country that demonstrate successful biogas-to-energy projects.
The University of California, Riverside is now home to a significant portion of the nationally acclaimed Water Resources Center Archives (WRCA), which began its move last week from Northern California to Southern California. Movers will complete the transfer of the prized collection from UC Berkeley to UC Riverside this week.
The move of the WRCA to UC Riverside sets the stage for planning a statewide network to be collaboratively supported by UC Riverside and California State University San Bernardino (Cal State San Bernardino will receive WRCA materials at a later date).
