Focus Report available for purchase. (Report included with US & Canada Municipal Insight service subscription).

More than US$234 billion of capital expenditures (CAPEX) are forecasted over the next decade to address aging municipal water & wastewater pipe network infrastructure. Precipitated by decades of underinvestment, municipal utilities are under increasing pressure to address deteriorating linear assets at a faster pace.

This Focus Report forecasts the capital expenditures (CAPEX) and factors shaping the rehabilitation, replacement, and new build across an existing network of 4 million miles of linear assets.


  • Ten-year Annual CAPEX Forecast
  • Forecast Methodology & Assumptions
  • Pipes by Material Type & Diameter
  • Network Hardware: Valves, Fittings, Hydrants, Manholes
  • State-by-State Geographic Segmentation
  • Market Drivers & Shifts
    (e.g. Housing Starts, Population)


  • What factors drive replacement, rehabilitation, and greenfield network CAPEX?
  • How are U.S. pipe distribution & collection networks segmented, geographically?
  • What are the emerging trends and market disruptors?
  • Which pipe materials will gain market-share over the next decade?
  • How are associated hardware impacted by network growth?
