Water and Wastewater Infrastructure Asset Management Tools


Improved performance of water and wastewater buried infrastructure is recognized as an issue of strategic importance because it has strong environmental, social and economic implications. The Centre for Advancement of Trenchless Technologies, in collaboration with the municipalities, has developed unique tools and techniques for effective, efficient and sustainable management of water and wastewater networks. The next-generation water and wastewater infrastructure management tools address the social, technical, and financial elements of asset management. Some of the salient features include:

  • Inventory: Tracking inventory of physical assets as they transit different condition grades due to inherent deterioration and rehabilitation/replacement interventions;
  • Maintenance Expenditures: Expected annual maintenance expenditures associated with pipes in various condition grades;
  • Rehabilitation Strategies: Impact of rehabilitation strategies on system service performance;
  • Financing Strategies: Formulation of different financing strategies such as ‘pay-as-you-go’, borrowing, building up/utilizing cash reserves, or a combination of these;
  • User Rates: Determining user rates under various financing strategies;
  • Water Demand and Conservation: Estimation of consumers’ average water demand as a function of user rates, annual flow volumes of supplied water and collected wastewater;
  • Annual expenditures itemized by operational and capital expenditures,
  • Annual operational expenditures further itemized by administrative, maintenance, water/wastewater treatment, and interest expenses,
  • Annual revenues, surplus or deficit;
  • Accumulated surplus or deficit;
  • Based on condition grades of pipes, calculation of water losses and extraneous flows; and
  • User friendly interfaces to quickly update the models with new data and create and explore various scenarios.
