Benefit-Cost Analysis of Using Geosynthetics in Water Resources
Increased water main breaks, leaking water reservoirs, and a lack of investment in infrastructure has left America's network of water systems in disrepair, warranting a D-minus grade from the American Society of Civil Engineers (ASCE, 2009). As certain regions of the United States, particularly the southwest, face water shortages, the need to rebuild the nation's water infrastructure is becoming increasingly important. This paper will present a cost-benefit analysis of constructing a composite liner system (geomembrane in combination with a GCL) to the expected savings in dollars from water saved. To evaluate their effectiveness in limiting water leakage, liner systems with and without an underlying GCL will be evaluated using tools commonly used in the landfill industry. Discount cash flow calculations indicate that the cost to construct a more robust liner will result in a net savings compared to the projected price of water lost over time from deteriorating reservoirs or those designed without a supporting low permeability secondary barrier.
