Trinity River Authority selects InfoMaster for wastewater system maintenance

 

Innovyze announced recently that the Trinity River Authority of Texas (TRA) has selected its InfoMaster software for use in prioritizing the operations and maintenance activities of its wastewater system.

TRA is a conservation and reclamation district providing water and wastewater treatment, along with recreation and reservoir facilities, for municipalities within the nearly 18,000-sq-mile Trinity River Basin. TRA owns and operates four water treatment facilities, five wastewater treatment facilities and one recreation project, and also manages water sales from four reservoirs. The National Association of Clean Water Agencies has recognized four TRA wastewater treatment systems with Peak Performance Awards. One of the largest, the Central Regional Wastewater System (CRWS), provides wastewater transportation and treatment for twenty cities and approximately 1.2 million people in the Dallas/Fort Worth area including the DFW International Airport. The CRWS includes a 162 MGD wastewater treatment plant and approximately 300 miles of pipelines ranging from 12-in. to 108-in. diameter interceptor pipelines.

InfoMaster helps us better understand the condition and performance of our wastewater system by giving us the advantages of analytics-driven, risk-based optimal pipe rehabilitation/replacement scheduling while fully leveraging our existing GIS and network simulation solution,” said John Durbin, collection system manager at TRA. “It also enables us to solve our most critical infrastructure problems; extend both asset service life and overall reliability, resiliency and performance; and determine the cash flow requirements for projects.”

Globally, aging wastewater infrastructures are rapidly deteriorating and sometimes failing — with potentially dire human, environmental and financial consequences. As this aging process continues, the need for effective risk-based asset integrity management becomes more pressing. Maintaining infrastructure assets in fit-for-purpose condition throughout their target lifespans is a primary goal for utilities worldwide, and selecting the right pipes for rehabilitation at the right time is one of the main challenges of asset management. An understanding of when and how pipes will fail, combined with a quantitative grasp of the underlying causal factors likely to induce failure, are essential in formulating a targeted approach to rehabilitation, repair and renewal planning.

Certified by NASSCO PACP, MACP and LACP, InfoMaster is the leading software choice for utilities faced with optimizing their sewer infrastructures and eliminating unwanted overflows. It can accurately estimate both the likelihood and consequence of failure for each individual sewer main in the network, as well as the amount and time of occurrence of future failures. This critical information facilitates a proactive approach to identifying and managing these high-risk assets to help preserve structural integrity and keep the network operating well into the future. It also eliminates reactive maintenance: waiting for pipe failures to occur before repairing.

InfoMaster comprehensive GIS-centric risk-based asset integrity modeling techniques provide reliable pipe failure predictions, even for limited failure records and application to different pipe materials. They include the non-homogeneous Markov Chain (NHMC), non-homogeneous Poisson process (NHPP), Linear Extended Yule Process (LEYP), Cox proportional hazards model, and advanced time-based probabilistic Weibull and Herz models. These techniques can be effectively used to evaluate a variety of pipe characteristics related to failure, and can consider all pipes in the sewer network, not just those with breaks or other failures. Armed with these powerful models, utilities can now accurately assess the aging processes of their network pipes and estimate their lifetimes and structural/functional failure potential and distribution over time. Such capabilities can greatly assist utilities in assessing their pipes’ propensity to fail, identifying critical ones (more prone to failure), prioritizing their inspection and determining rehabilitation requirements. This proactive “fix before break” approach can help utilities extend the useful life of their assets and improve their performance at maximum savings.

The InfoMaster product suite can import hydraulic modeling data and facilitate significantly better planning and control by giving utilities critical insight into all enterprise assets, their conditions, aging and work processes. It also features direct integration with Cityworks (Azteca Systems Inc., Sandy, UT), Cartegraph (Dubuque, IA), infraMAP (iWater, Irvine, CA) and Lucity (Overland Park, KS), and can interface with other leading maintenance management software (CMMS). InfoMaster enables utilities to use information and analytics in new ways to drive higher productivity and quality while managing costs and increasing operational flexibility.

The program’s intuitive interface; easy-to-use functionality; and rich analytical, graphing and reporting capabilities save utilities considerable resources. With minimal effort, users can quickly pinpoint assets at the greatest risk of hydraulic and water quality deficiencies or structural failure, identify the best possible improvement alternatives for optimal system performance, prioritize improvements based on available budget, and realize significant cost savings.

The software also serves as a base platform for advanced asset management extensions including InfoMaster LCCA (Life Cycle Cost Analysis) and InfoMaster WMS (Work Management System). InfoMaster LCCA lets utilities conduct a wide-ranging risk-based economic life-cycle cost analysis to determine the optimal replacement date for each pipe in the network. This enables users to ensure the smartest distribution of dollars spent on replacement and repair of their assets. It also helps them create reliable, cost-effective, risk-based capital improvement plans that enhance operational efficiency and quality of service and keep assets performing at peak condition while making the most of limited budgets. InfoMaster WMS lets utilities manage the entire lifecycle of work orders and inspections. A complete ArcGIS-centric CMMS solution, it saves enterprises valuable time and money by better organizing, planning and proactively managing all maintenance activities.

“Strong asset performance modeling and capital planning capabilities are critical components of a smart enterprise asset management strategy,” said Erick J. Heath, P.E., Innovyze’s business director – Americas. “InfoMaster delivers detailed, accurate analyses and comprehensive custom reports that help utility managers make better, more informed decisions on when to repair, replace, or rehabilitate their critical sewer network assets; eliminate potential overflows; and optimize efficiency, maintenance and hydraulic performance. It also supports them in developing reliable long-term funding strategies for such projects. These advantages help utilities ensure the ongoing sustainability and resiliency of their infrastructures and their ability to deliver the required level of service at the lowest cost. As a key component of this complex synthesis, Innovyze is proud to continue to be a part of the Authority’s success.”
