This is an outline of the major milestones associated with land application for CRWS biosolids
CRWS biosolids disposal costs 2011-2017.

TRA has a solids master plan for the Central Regional Wastewater system. This slide shows the different solids processing options that were evaluated along the horizontal axis. The vertical axis shows the Operations and Maintenance cost in 2014 dollars for each option. Thermal Hydrolysis is the least costly, primarily due to the anticipated solids volume reduction by 50%.
A slide showing the O&M cost and capital cost for each of the solids processing options evaluated. THP is the purple line. The THP option shows anticipated savings of $150M when compared to the cost of our current lime process over the next 30 years.
