Can You Please Hold It In For A Few Months?

The City of Portland’s Columbia Boulevard Wastewater Treatment Plant is the largest plant in Oregon. With this comes a huge responsibility, and, sometimes, humbling lessons. In July 2018, plant operations realized things were amiss, where treatment performance degraded despite being in dry season. The culprit? Biosolids accumulation in the otherwise tranquil CBWTP’s lagoons that had crept up and now threatened the performance of plant operations. Several factors contributed to the situation that was eventually raised to an emergency.

This presentation will focus on the extraordinary efforts and collaboration between operations, maintenance, engineering, and procurement to find the root cause of treatment plant performance issues and develop a path forward that would protect public and watershed health, providing a renewed appreciation of biosolids management and, most importantly, teamwork.

2:00pm - 2:45pm

Want a Successful Project - Start with O&M

Joan Hawley

Superior Engineering, LLC (WEF Representative), United States of America;

Resource Recovery is becoming the norm for water resource recovery facilities rather than the unique. Many different types of technology are being installed – some successfully and some not so successfully. This presentation will focus on why operation and maintenance (O&M) is so critical to consider first and throughout the process for resource recovery and other new types of technology rather than after the project has been designed.

Operators are a key resource for a project to be successful and this includes front-line operators as well as maintenance and applicable staff. The operator perspective are invaluable from the facilities operation, to safety, to determining what type of skill sets will be needed to operate and maintain the new facilities. While many projects include these team members their input may be too late, or the key people are not in the decision-making process.

A couple of simple considerations will help ensure that the installation, startup and operation go more efficiently and effectively. This presentation will also focus on several projects that had various levels of success and what would they have done differently. And as more than one operator told me – there is no perfect technology or equipment that will solve all the problems… but with team-work the project can be successful.
