Water System Vulnerability Assessments
We evaluate all system vulnerabilities from source to tap using the Army’s Risk Management Approach as well as the Sandia Ram-WSM methodology. We can conduct your WSVA, review completed assessments, and provide guidance on initiating the vulnerability assessment process.
Emergency Response Plans
We can compose or update water system emergency response plans (WSERPs) for any type of potable water system. WSERPs provide guidance for water purveyors in the event of a natural or man-made disaster affecting the supply and distribution of potable water. The fully developed water system ERP provides response actions related to high-risk vulnerabilities identified in the water system vulnerability assessment.
Unidirectional Flushing Plans
The purpose in developing a unidirectional flushing procedure for an installations drinking water system is to provide the Environmental and Utilities Division with the means to effectively flush their system annually or during an emergency response to contamination. This will bring the installation into compliance with AR 200-1, Environmental Protection and Enhancement, which requires installations to have a systematic flushing plan with adequate scouring velocities. The building of the computer model will allow the flushing sequence to be simulated and validated before being implemented on the actual system.
Initial Distribution System Evaluations
The purpose in performing this project is to assist installations in meeting the Initial Distribution System Evaluation (IDSE) requirements of the Stage 2 Disinfectants Disinfection By-Products Rule (Stage 2 DDBPR). This project follows the Standard Monitoring Program (SMP) of the IDSE for identification of future Stage 2 DDBPR Total Trihalomethane (TTHM) and five Haloacetic Acids (HAA5) compliance monitoring sites.
Cross Connection Control and Backflow Prevention Survey
On-site evaluation of the installation water flow system to determine where potential cross-connections or backflow conditions may exist and possibly result in contaminated potable water supplies. The survey report provides a listing all buildings surveyed, the location of potential problem areas, and what practices should be put into place to prevent cross-connections or backflow.
Water Conservation Plans
The water conservation plan identifies how an installation might implement water conservation practices recommended by the Department of the Army (DA), State guidelines, and the U.S. Environmental Protection Agency (USEPA).
