Delta Diablo District
What Our Clients Say:
The Kennedy Jenks Team’s performance on the Business Risk and Vulnerability Analysis (BRVA) was crucial to identifying a phased approach to achieve the District’s Reliability and Asset Management Program. Kennedy Jenks has been highly responsive throughout this project, winning the trust of our operations, maintenance, engineering, business and management teams, bringing added value, and keeping the project on-track and on budget.
Kennedy Jenks assessed over 34,500 feet of gravity sewer pipe within a four-week period as part of a regulatory requirement to assess all infrastructure within 200 feet of a waterbody.
This work required establishing tight performance requirements with the CCTV subcontractor to complete the necessary production within the demanding schedule. The gravity sewers inspected ranged from 6 to 42 inches in diameter and were assessed using the National Association of Sewer Service Companies (NASSCO) Pipeline Assessment Certification Program (PACP) 2016 standard. The results of this initial effort were completed to meet the regulatory requirements and were added to a growing database of inspection data as part of the District’s centralized asset registry. In conjunction with the gravity sewer inspections, Kennedy Jenks helped oversee inspection of more than 100 manhole structures.
These data are connected to GIS to streamline illustration and comparison of risk levels with adjacent assets. Kennedy Jenks also helped the District complete its first inspection of the WWTF Outfall pipeline, which was presented at the 2019 CWEA Annual Conference. These efforts are being completed in advance of the District’s Master Plan to better understand and manage its most critical assets.
The results of this project have been merged with a separate District-wide BRVA, also completed by Kennedy Jenks, and both are now helping prioritize replacement and rehabilitation actions. In particular, the results are being used to advertise a large-scale manhole rehabilitation project in the near future.
