Plant Monitoring/Training/Consulting Retainer
This service is set up for a fixed monthly fee. The basic service (plant monitoring) includes a monthly microscopic examination of your sludge combined with a review of your operating data spread sheet. A brief report is provided combining a summary of observations with the findings of Dr. Michael Richard, including suggestions for maintaining or optimizing your treatment plant performance. Included with this basic service is unlimited telephone consulting. This service should help you identify potential problems and prevent them from becoming major operational challenges.


  • Annual refresher training. After a year of reviewing plant data and operational events, we will be prepared to provide site-specific training which focuses on those topics most critical to your facility. The year's data will be readily available to use, along with customized graphs, for analyzing and troubleshooting activities during the workshop. Now being familiar with your plant, training preparation time ­ and therefore costs ­ are lower through this option than as a stand alone project.
  • Annual Audit. Review plant operations and provide recommendations to optimize operations. Again, the cost of an audit is lower through this service because of existing familiarity with the data and operational issues during the past year.

A fixed monthly retainer fee, based on the options selected, would be set up for a year. The payback for this service will be realized through cost savings as a result of implementing the recommendations and suggestions for optimizing operations. Also, consulting costs will be lower by combining these options instead of conducting them separately.
