Dallas, TX — February 25, 2019 — At their November 2018 meeting, the City Council of Temple awarded a $1.6 million contract to RJN Group, Inc. for the development of a citywide System Evaluation and Capacity Assurance Plan, or SECAP, for Temple’s 400-mile-long sanitary sewer system. RJN will devise the SECAP as a guide to ensuring that the City’s sanitary sewer collection system has the capacity to adequately transport flows downstream during peak wet-weather events. Additionally, RJN will also assess infrastructure conditions to identify sources of inflow and infiltration, which contribute to increased downstream flows.
“We are excited to finally be in a position to address these wastewater collection issues that have been outstanding for decades,” said Damon B. Boniface, utility director for the City of Temple. “We are also thankful that the City has partnered with RJN Group, a robust firm that is well-grounded in providing superior professional services for this type of work, for the betterment of the Temple community.”
With the awarding of the contract, RJN technicians began conducting the initial field work in December. This includes conducting GPS mapping, flow monitoring and other related field services to aid in the development of a holistic understanding of the collection system. From these findings, RJN engineers will develop a strategic plan of approach which will prioritize rehabilitation efforts based on areas with the greatest need.
Additionally, RJN will begin what is the first phase of a basin-by-basin assessment program to identify sources of inflow and infiltration—flows that emanate from defects, illegal connections to the sanitary sewer, and/or are otherwise not a typical component of traditional sources of sewage—and provide remediation recommendations.
“Our goals, as with all RJN projects, are not only to help the City of Temple realize cost savings through more efficient collection system operations, but to assist them in their efforts to be better stewards to their community,” said RJN Principal and Vice President, Daniel Jackson, P.E.
“We will achieve these goals by putting our expertise and resources to work for the City of Temple with the design of an effective plan that will ensure pipeline efficiency and ultimately reducing or eliminating capacity issues which lead to overflow conditions,” he added.
The project includes flow monitoring to evaluate flows transported through more than two million linear feet of sewer pipeline, which will be used to create a systemwide hydraulic model, and evaluating the condition of 323,000 linear feet of sewer and 1,027 manholes through a combination of smoke testing, dye flooding, manhole inspections, and video pipe inspections.
