  An empirical model for the prediction of structural behavior of wastewater collection systems

  Rizwan Younis

  tructural condition of wastewater pipelines is often reported in terms of internal condition grades of 1 through 5

  with 1 being the best and 5 the worst condition. The existing models and methodologies for structural deterioration of wastewater pipelines based on ordinary regression or ordinal probit regression violate the model assumptions

  and lead to invalid results. Furthermore

  the existing ordinal probit models for structural deterioration of Civil infrastructure are overly complex in terms of number of parameters to be estimated. This also makes the interpretation of these models fairly challenging. Another existing modeling technique based on binary logistic regression dichotomizes the data into pass/fail categories

  and thus ignores the rank order information available in data. This paper demonstrates the shortcomings of existing methodologies

  and presents an ordinal regression model based on cumulative logits with partial proportional odds for modeling the structural degradation behavior of wastewater pipelines. The proposed model is more parsimonious as compared to the existing ordinal probit models as less number of parameters needs to be estimated. The model is also more flexible as it does not assume an overly strict assumption of normally distributed error terms. The model also affords simple interpretation in terms of odds and predicted probabilities. Application

  parameters estimation

  verification of assumptions

  graphical interpretation

  and model validation has been demonstrated with real data from the City of Niagara Falls' wastewater collection system. The paper concludes with a discussion of the salient features of the proposed model

  and its implications for wastewater systems' performance prediction research.

  Recently enacted regulations in Canada and elsewhere require water utilities to be financially\nself-sustaining over the long-term. This implies full cost recovery for providing water\nand wastewater services to users. This study proposes a new approach to help water\nutilities plan to meet the requirements of the new regulations. A causal loop diagram is\ndeveloped for a financially self-sustaining water utility which frames water and wastewater\nnetwork management as a complex system with multiple interconnections and\nfeedback loops. The novel System Dynamics approach is used to develop a demonstration\nmodel for water and wastewater network management. This is the first known application\nof System Dynamics to water and wastewater network management. The network simulated\nis that of a typical Canadian water utility that has under invested in maintenance.\nModel results show that with no proactive rehabilitation strategy the utility will need to\nsubstantially increase its user fees to achieve financial sustainability. This increase is\nfurther exacerbated when price elasticity of water demand is considered. When the utility\npursues proactive rehabilitation

  financial sustainability is achieved with lower user fees.\nHaving demonstrated the significance of feedback loops for financial management of water\nand wastewater networks

  the paper makes the case for a more complete utility model that\nconsiders the complexity of the system by incorporating all feedback loops.

  Causal loop diagrams are developed for wastewater collection networks to identify complex interactions and feedback loops among physical

  financial

  and social sectors. Causal loop diagrams are then incorporated into a novel system dynamics based decision support tool that can be used for financially sustainable management of wastewater collection networks. Data requirements to develop the decision support tool are also discussed along with how the decision support tool can be used to manage a utility.\nThe presented causal loop diagram is the first known attempt to lay out the interrelationships among system components using a formal technique. The causal loop diagram establishes the existence of several interacting feedback loops and demonstrates that the management of wastewater collection networks constitutes a complex dynamic system for which traditional management tools are deemed inadequate. The use of causal loop diagrams can be useful to mitigate effects of the silo-based organizational culture prevalent in many water utilities. \nThe system dynamics model is the first known decision support tool to quantitatively simulate the influence of interrelationships and feedback loops in wastewater collection network management. The model is a mathematical representation of the causal loop diagram to capture cost drivers and revenues sources in the system. It also includes a set of policy levers which allow formulation of various financing and rehabilitation strategies. The model can be used to develop short- and long-term management plans. The impact of financing and rehabilitation strategies on system performance can be simulated and evaluated in terms of financial and service level metrics. The decision support tool can also be used by utilities to ensure essential data is collected and flows within organizational units.

  This paper describes a structured framework for the design and construction of horizontal directional drilling (HDD) projects. This framework is implemented in a new HDD software design program BoreAid. The framework consists of five interlinked modules: 1) bore planner; 2) load/deflection calculator; 3) drill planner; 4) bore pressure estimator; and 5) equipment/tooling selection. Each module is discussed in detail and a case study example is presented to demonstrate how this new framework methodology can be used as a HDD project quality assurance and quality control tool and to increase the probability that the project will be completed on time and within budget by ensuring industry good practices are followed.

  This paper demonstrates how the condition assessment data from trenchless visual inspections of\nwastewater pipelines can be used to understand the performance of wastewater pipelines. A new ordinal regression model for the deterioration of wastewater pipelines based on cumulative logits is elaborated. The model is presented using the Generalized Linear model formulation and takes into account the interaction effect between the explanatory variables. The new model is demonstrated and validated using the City of Niagara Falls high quality wastewater collection network condition assessment data for reinforced concrete (RC) and vitrified clay (VC) pipes. This new model is found to represent the City of Niagara Falls RC and VC pipes’ deterioration behavior for pipes in service for up to 110 years. RC pipes deterioration is found to be age dependent while VC pipes deterioration is not age dependent. This finding is contrary to other deterioration model studies\nthat indicate that VC deterioration is age dependent. The service life for RC pipes is estimated to be\napproximately 75 years while VC pipes are found to have an indefinite service life if installed without\nstructural damage. The cumulative logit model can be used to determine wastewater pipelines’ service life

  predict future condition states

  and estimate networks’ maintenance and rehabilitation expenditures. The latter is critical if realistic wastewater networks’ future maintenance and operation budgets are to be developed for the life of assets and to meet new regulatory reporting requirements. Further research is required to validate this new methodology for other networks and the deterioration modeling of pipe materials other than RC and VC.

  A probability model for investigating the trend of structural deterioration of wastewater pipelines

  This paper presents the development of a novel system dynamics (SD) model for better understanding the interrelation and feedback mechanism between the wastewater collection (WWC) and wastewater treatment plant (WWTP) systems. Causal loop diagrams (CLDs) are developed and discussed to depict and understand feedback and inter-connections between physical

  financial

  and consumer sectors. The developed SD model is then extended to include the greenhouse gas (GHG) emissions

  as a proxy for the environmental sector and for an environmental sustainability assessment of strategic decisions related to asset management planning of wastewater infrastructure system. It also adds new policy levers

  such as population growth and urban densification in the social sector

  and minimum fee-hike rates in the finance sector to enhance the representation of real-world conditions in the asset management planning. This new SD model will enable decision-makers to assess the sustainability impacts of their strategic decisions on wastewater systems

  find synergistic cost-saving opportunities

  and improve the sustainability performance of their asset management plans.

  PPI-BoreAid is a free online tool that allows users to perform preliminary pipe design analysis for polyethylene (PE) pipes installed using a horizontal directional drill (HDD). It allows users to determine suitable PE pipe dimension ratios (DR) to satisfy installation and in-service loads required in ASTM F1962 and Chapter 12 of the Handbook of Plastics Pipe Institute (PPI) Polyethylene Pipe Design

  2nd edition. During PPI-Boreaid development

  several conservative aspects of the current PE pipe design methodology and PE pipe properties were noted. This paper discusses the requirement for the development of PPI-BoreAid as a preliminary PE pipe design tool

  and provides suggested changes to the aforementioned documents. Sample calculations are presented to demonstrate how the new application can be used to select a suitable PE pipe for a site specific HDD project.

  Over the past decade

  many performance indicators have been developed for water utilities to track their system performance. This study proposes a set of normalized and time-integrated benchmarking performance indicators for sustainable long-term management of water\ndistribution and wastewater collection networks. The benchmarking performance indicators are aggregated into three categories: (1) infrastructure

  (2) sociopolitical

  and (3) financial. To demonstrate the use and value of the benchmarking performance indicators

  a system dynamics\nmodel is used to present a case study for three water utilities in southern Ontario

  This study demonstrates how to implement a novel system dynamics (SD) strategic water utility management and financial planning tool. Using data from several local water utilities in Ontario

  Canada

  the tool is run to simulate 20 years to investigate: (1) long-term fee-hike rates required for system financial sustainability; (2) service and financial performance metrics for pay-as-you-go

  borrowing

  and capital reserving strategies; and (3) consumer affordability as a result of water use charges. For the case study

  reserving cash and allowing water fees to increase by up to 7% per year are found to be the best financing strategy to eliminate infrastructure backlog/deficit. The study demonstrates the benefits of an SD model for developing and preparing strategic and tactical asset management

  water conservation

  and financial plans. The SD model parameterization and implementation for the demonstration case study can be helpful to other utilities in adapting the model to their own specific circumstances.

  This paper presents a framework to develop

  implement and communicate a multi-perspective asset management plan for wastewater collection networks. The framework takes into account four strategic perspectives – socio-political

  financial

  operational/technical

  and regulatory – and devises four strategic themes for sustainable wastewater collection systems. The asset management strategic themes

  perspectives

  and strategic objectives were developed from \nthe proceedings of collaborative working sessions held at the first Canadian National Asset Managers workshop in 2007 in Hamilton

  Ontario. The themes and strategic objectives are illustrated in a strategy map and detailed in the modified balanced scorecard model. A case study based on real data presents the use of business intelligence tools to implement

  monitor

  and report various components of the proposed framework. The proposed framework provides a unified gateway for efficient and effective management of waste-water collection systems. It can be adapted to devise and implement strategic asset management plans in comparable organizations

  and to comply with the new legislative requirements that demand increasing accountability to meet stakeholders’ expectations

  protection of public health and environment

  efficient allocation of funds

  and greater disclosure.

  Water Research

  This paper develops causal loop diagrams and a system dynamics model for financially sustainable management of urban water distribution networks. The developed causal loop diagrams are a novel contribution in that it illustrates the unique characteristics and feedback loops for financially self-sustaining water distribution networks. The system dynamics model is a mathematical realization of the developed interactions among system variables over time and is comprised of three sectors namely watermains network

  consumer

  and finance. This is the first known development of a water distribution network system dynamic model. The watermains network sector accounts for the unique characteristics of watermain pipes such as service life

  deterioration progression

  pipe breaks

  and water leakage. The finance sector allows for cash reserving by the utility in addition to the pay-as-you-go and borrowing strategies. The consumer sector includes controls to model water fee growth as a function of service performance and a household’s financial burden due to water fees. A series of policy levers are provided that allow the impact of various financing strategies to be evaluated in terms of financial sustainability and household affordability. The model also allows for examination of the impact of different management strategies on the water fee in terms of consistency and stability over time.\n\nThe paper concludes with a discussion on how the developed system dynamics water model can be used by water utilities to achieve a variety of utility short and long-term objectives and to establish realistic and defensible water utility policies. It also discusses how the model can be used by regulatory bodies

  government agencies

  the financial industry

  and researchers.

  This study develops and demonstrates a wastewater system dynamics model as a decision support tool that can assist utility managers to ensure financial sustainability while maintaining customer expectations for service performance. To achieve implementation of the model

  a demonstration case study is developed using data from a medium-sized city in Ontario

  Canada

  having a large backlog of deteriorated wastewater pipes. Specific outcomes for this study include: 1) presentation of a methodology to parameterize the demonstration model using available utility data; 2) demonstration of the significance of interrelationships between system variables on a system’s performance indicators such as total life-cycle costs

  Internal Condition Grade of pipes

  sewage fees; and 3) exploration of alternative financially sustainable management strategies for operating a wastewater network that involve the trade-offs between maintaining a strict ‘zero fund balance’ with no borrowing

  versus issuing debt to accelerate a capital works program.\nResults indicate that a financing strategy involving borrowing can minimize the total life-cycle cost while maximizing the service performance level of the network. \n

  This paper presents a new ordinal regression model for the deterioration of wastewater pipelines based on continuation ratio logits. The model provides estimates of conditional probabilities for a pipeline to advance beyond a particular internal condition grade – to worse condition – depending on pipe material and age. The model development and validation procedure is demonstrated using high quality condition assessment data for reinforced concrete (RC) and vitrified clay (VC) pipes from the City of Niagara Falls wastewater collection system. The new model is found to represent the RC and VC pipes’ degradation behavior for in-service pipes up to 110 years of age at the City of Niagara Falls wastewater collection system. RC pipes’ deterioration is found to be age dependent while VC pipes’ deterioration is not age dependent. The VC pipe finding is contrary to other deterioration model studies that indicate that the type of pipe material is not significant and that the\ndeterioration of VC pipes is age dependent.\n\nThe findings from the continuation ratio model can be used for risk-based policy development for maintenance management of wastewater collection systems. The proposed model can help in devising appropriate intervention plans and optimum network maintenance management strategies based on pipelines’ age

  material type

  and internal condition grades. These predictions are critical if realistic wastewater networks future maintenance and operation budgets are to be developed over the life of asset and to meet new regulatory reporting requirements. Further research is required to validate the proposed model in other networks and to determine if the method can be used to model the deterioration of pipe materials other than RC and VC.
