Business Intelligence for Water and Sewer Systems

Globally, aging water and wastewater infrastructures are rapidly deteriorating and sometimes failing — with potentially dire human, environmental and financial consequences. Deterioration can increase gradually with time, or occur in discrete steps. As this aging process continues, the need for effective asset integrity management becomes more pressing. Maintaining water and sewer 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 asset management challenges. When estimating the service lives of pipes, utilities have generally relied on predictions of the durability of the pipe materials with which they are constructed. However, because of varying environmental and climate conditions, soil type, pipe size, internal corrosion, quality of installation, transient pressure and operational pressure zone changes, and other factors, this method is not always accurate. One reason is that because most pipes are buried, there is little data available about how they deteriorate and fail.

A highly advanced and powerful infrastructure condition prediction modeling tool, InfoMaster lets you optimize your water and sewer network rehabilitation prioritization and capital planning programs, taking infrastructure maintenance out of the break and fix approach into the fix-before-break era.

An understanding of how pipes fail, combined with a quantitative grasp of the underlying causal factors likely to induce failure, is valuable in formulating a targeted approach to rehabilitation, repair and renewal planning. InfoMaster accurately estimates both the likelihood (condition) and consequence of failure/criticality (the impact of a failure in terms of repair cost, disruption to the public and economy, impairment of system operation, regulatory compliance, public health and safety, and damages to the environment) for each individual pipe 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. With minimal effort, utilities can quickly pinpoint assets at the greatest risk of failure, identify the best possible improvement alternatives for optimal system performance, prioritize and phase improvements based on available budget, and realize significant cost savings.

Out-of-the-Box Data Hub

Unlike many traditional business intelligence applications, InfoMaster comes preconfigured to understand water and sewer networks. InfoMaster knows that sewer pipes have upstream and downstream manholes, a hydrant is connected to the distribution system with a lateral, scoring of CCTV defects, and dozens of other items functionality specific to water networks. The database leverages the existing ArcGIS water and wastewater data models to include the ability to store information about incidents and tasks related to the network. Central to InfoMaster is its ability to exchange with other enterprise CMMS or ERP databases enabling a true 360 degree view of the infrastructure.

(CCTV acceptance inspection and condition assessment of sewers is standard practice in the U.S., Australia, New Zealand, UK and EU. The PACP, MACP and LACP programs of the US National Association of Sewer Service Companies (NASSCO); the Conduit Inspection Reporting Code of Australia WSA05, published by the Water Services Association of Australia; the New Zealand Water and Wastes Association Pipe Inspection Manual; the UK MSCC4 Inspection Codes; and the EU Visual Inspection Coding Systems EN 1350802, provide guidance to utilities in determining the acceptability of sewer defects and features.)

Importance of InfoMaster Comprehensive Condition Assessment

Condition assessment enhances the ability of utilities to make technically sound judgments regarding asset management. Some utilities presume that older pipe must be in poorer condition than newer pipe, which is not always the case. There are many examples showing 80 year old pipe in excellent condition and 30 year old pipe near failure. The only way to know for sure is to take a look – perform a condition assessment. Being able to organize the assets of your system by maintenance and replacement needs is an essential step toward better management.

Specific benefits of a formal condition assessment program include:

  • Early identification of problems (resulting in use of less expensive repair methods)
  • Reduced emergency consequences by identifying and addressing previously unknown problem areas
  • Reduced O&M costs (e.g., by identifying and cleaning only the “dirty” pipes during operation and maintenance programs)
  • Avoided emergency costs due to scheduled preventive maintenance
  • Avoided service disruptions by up-front scheduling of preventive maintenance
  • Avoided or mitigated Sanitary Sewer Overflows (SSOs) or pipeline breaks and associated costs from environmental and property damage
  • Avoided public health costs
  • Improved planning and prioritizing of rehabilitation and replacement projects
  • Reduced backlogs of deferred maintenance
  • Identification and prediction of future Capital Renewal needs
  • More effective and efficient operations and maintenance.

Pipe Failure/Deterioration Modeling

InfoMaster lets you accurately predict pipe failure to reduce renewal and maintenance costs, and improve reliability and customer service.

InfoMaster features the non-homogeneous Markov chain process (NHMC), non-homogeneous Poisson process (NHPP), Linear Extended Yule Process (LEYP), Cox proportional hazards model, and advanced time-based probabilistic Weibull and Herz models for modeling the aging processes of water and wastewater network pipes and accurately estimating their lifetimes and structural/functional failure potential and distribution over time. These powerful asset integrity modeling techniques let users accurately estimate the likelihood of pipe breaks in the future and determine the parameters that most affect that likelihood. These may include pipe diameter, length, material, year of installation, location, operating pressure, rainfall, land use, soil properties, temperature, traffic loads, seismic zone, ground water level, proximity of other underground installations, and history of failure. Understanding these factors gives utilities an optimized, mission-critical basis for rehabilitation prioritization and failure prediction. Economic-based Nessie curves are also available to plan for the future cost of asset replacement. These curves are based on the design life of the pipelines and not on structural condition and failure considerations.

InfoMaster provides reliable pipe failure predictions, even for limited failure records and when applied to different pipe materials. It also features complete Business Risk Exposure (BRE) redundancy calculation derived from sophisticated graph-theoretical loop generation algorithms. The software can greatly assist water and wastewater utilities in assessing their pipes’ propensity to fail, identifying critical ones, prioritizing their inspection, and determining rehabilitation requirements.

Valve Criticality Modeling

InfoMaster automatically identifies all critical valves in terms of their potential impact on the customer levels of service, either when they are shut or fail to shut, during planned or emergency work — enabling maintenance and replacement to be targeted to those valves. The consequence of each valve operation can be measured in terms of the number of properties being disconnected or receiving an unacceptable level of service (e.g., low pressure). These capabilities help water utilities develop an optimal investment regarding valve maintenance, minimizing the impact on customer levels of service and improving knowledge on the operation of the network.

Proactive Capital and Operational Planning

InfoMaster gives utilities a new perspective on their capital and operational planning. Armed with a clear view of their infrastructure condition, capital and recurring costs, likelihood of failure, consequence of failure, historical incidents and maintenance, planners and managers can revamp capital and operational plans. Utilities can shift operational budgets away from reactive and into proactive management.

Comprehensive Scenario Comparison

InfoMaster provides a comprehensive scenario comparison tool that allows users to easily track, review, analyze and validate any number of scenarios, instantly compare different asset renewal planning strategies, and select the best alternative. This powerful capability helps users effectively optimize their Capital Improvement Programs (CIPs).
