Waste and drinking water projects are particularly underfunded. ASCE predicts that sector will receive only a third of its required funding by 2020.

Roads and surface transportation will only get about half their projected $1.7 trillion need for capital projects. Inland ports and waterways also are funded at about of their needs.

The electric grid and airports fare better, receiving most of the funding they require, according to ASCE.

People may feel the financial impact of underinvestment most directly on the roads. Researchers at the Texas A&M Transportation Institute estimate that, unless spending increases, congestion and rough roads will cost the average Texas household $6,100 a year in wasted fuel, vehicle repairs, and time lost sitting in traffic between now and 2035.
