Abstract:Due to rapid growth in population and construction activity, the demand of good quality water continues to increase in many parts of Texas. The use of non-conventional, or “alternate,” sources of water as a substitute for quality drinking water in construction applications could potentially reduce the cost of construction while conserving quality water resources. The primary objective of this research project was to identify alternative water sources that may be used in construction applications such as pavement subgrade, base, embankment fill and structure backfill compaction, vegetative watering, soil stabilization, and dust control. The alternate sources of water considered in this study are: wastewater from municipal wastewater treatment plants, brine water from oil wells, surface and groundwater that do not meet the drinking water quality standards, and ocean water. The various issues addressed by this research project are the effect of alternate water on construction materials, legal issues addressing the use of alternate water in Texas, safety and health concerns of workers and the public, and the impact on the environment by the use of low quality alternate sources of water. A decision matrix is presented to facilitate the evaluation of alternative water construction applications combinations.
