Haights Creek Rpm Pipe Failures, United States Department Of The Interior, Bureau Of Reclamation
Water
In 1989, Haights Creek Irrigation Company replaced 730 linear feet of 24- and 27-inch-diameter RPM (reinforced plastic mortar) pipe because of several failures. Bureau of Reclamation personnel examined the pipe before and after exhumation, the surrounding soil conditions, and measured diametral deflections. Major longitudinal cracks in the pipe invert appear to be the result of hard spots in the pipe foundation. Some of these hard spots were caused from mounding, or using a mound of soil under one end of the pipe to bring it to grade without providing an equivalent uniform support along the remainder of the pipe.

Water
Urban water use, particularly outdoor use, responds to changes in temperature, precipitation, and other climatic parameters. This study significantly improved the capacity of an existing regional water demand model to estimate the response of both residential and commercial-industrial water demand to changes in climatic parameters. The resulting functional relationships derived from historic time-series climatic and water use data were applied to global climate scenarios for the four Wasatch Front counties of Utah.
