| 4450 | Impact of Water Quality on Hexavalent Chromium Removal Efficiency and Cost | 4450 - Impact of Water Quality on Hexavalent Chromium Removal Efficiency and Cost The objectives of this project are to: 1) evaluate the impact of different water quality conditions on the removal efficiency of hexavalent chromium [Cr(VI)] and total chromium (total Cr) with leading technologies; and 2) provide capital and operations and maintenance (O&M) cost curves for implementing treatment modifications necessary to overcome such impacts and comply with a range of potential drinking water maximum contaminant levels (MCLs) ranging from 1 microgram per liter (µg/L) to 20 µg/L.

| 4451 | Utility Risk Management Methodologies for Buried Assets with Improved Triple Bottom Line Understanding of Pipe Failures | 4451 - Utility Risk Management Methodologies for Buried Assets with Improved Triple Bottom Line Understanding of Pipe Failures This project will develop an increased understanding of the application of risk management concepts to infrastructure of potable water utilities. This assessment must accurately take into account the capital cost of the infrastructure, the costs and consequences of failure, and the imprecise ability to predict remaining asset lifespan due to lack of complete understanding of deterioration mechanisms and imprecise condition assessment techniques. Also, the ability of the water industry to express possible consequences of failure is relatively limited, lacking rules of thumb, and lacking understanding of basic issues. This project will develop a considerably increased understanding of the consequences of infrastructure failure through case studies. The business case for risk mitigation can be made stronger if the benefits of avoiding a risk of asset failure can be quantified and compared to the cost of the mitigation action. The quantification of the consequence of failure, as proposed in this project, can be used in the business case. Close Details | Water Utility Infrastructure |

| 4458 | Water Demand Forecasting in Uncertain Times: Isolating the Effects of the Great Recession | 4458 - Water Demand Forecasting in Uncertain Times: Isolating the Effects of the Great Recession Assess how water demand is affected by short-term economic shocks, such as the recent recession, and how that can be differentiated from the many other factors known to have an impact on demand. Discuss how water utilities may be better able to anticipate, adapt to, and minimize impacts of future economic cycles on water demand planning. Close Details | Water Demand |
| 4459 | Development of a Biofiltration Knowledge Base | 4459 - Development of a Biofiltration Knowledge Base The objective of this project is to catalog and summarize the design, operation, and monitoring of the hundreds of biologically enhanced rapid-rate filtration facilities in North America. By identifying and analyzing existing biofiltration facilities, the project is expected to: 1) Widely communicate the benefits of biofiltration, 2) Identify the water quality benefits of biofiltration, while providing lessons learned on mitigating any negative impacts and 3) Provide guidance to utilities to improve the initial design and on-going operations of biofiltration facilities.

| 4460 | Practical Condition Assessment and Failure Probability Analysis of Small Diameter Ductile Iron Pipe | 4460 - Practical Condition Assessment and Failure Probability Analysis of Small Diameter Ductile Iron Pipe The project will develop a manual of practice for condition assessment (CA) and related evaluations of small diameter (12” and smaller) ductile iron (DI) pipes in order to help utilities assess their pipe inventory and identify those pipes most in need of renewal. This work will be based on what is available now in terms of CA technologies to include information about costs and limitations of each technology. Close Details | Water Utility Infrastructure |
