In December 1990, the Oklahoma State Health Department (now ODEQ) placed the City of Tulsa under a Consent Order due to wastewater overflows and system backups (SSOs). The City hired RJN in 1993 to conduct a comprehensive sewer study, including hydraulic modeling, of the Coal Creek sanitary sewer basin. RJN followed the study with a plan for design of priority 1 through 4 capacity improvements throughout the basin to eliminate chronic rain-induced SSOs. RJN has continued to work for the City providing construction oversight and design services and is currently providing design services for the remaining priority 4 improvements to increase system capacity through a Specific Remediation Plan Program in the Upper Coal Creek Basin and extend services in the Spunky Creek Basin. Following the capacity improvements, RJN will recommend a follow-up Sanitary Sewer Evaluation Study (SSES) and sanitary sewer rehabilitation program to protect the City’s sanitary sewer interceptor investments. The local staff in the Tulsa office is proud to assist the City of Tulsa with its wastewater collection needs.
