Analyzing the data in this way will help you understand current water use trends.Īt the agency level, this step involves collecting detailed water use and cost data and real property inventory from all sites. Is there a seasonal pattern to water use? This is often the case when irrigation water is used or cooling water demand increases in the summer months. Try to determine what caused the major trends.Is water use increasing, decreasing, or steady? If monthly data are available, plot the monthly use over time. Determine a baseline annual water use for a specific year or an average water use over several years.Production information if the facility produces its water or treats its own wastewater, or both.Īfter collecting water use data, take the following substeps:.Contact information for the federal agency or office that pays the water and sewer bills.Energy utilities often offer assistance with water-efficiency programs Information about rebates or technical assistance from the utilities to help with facility water planning and implementing water-efficiency programs.Copies of water and sewer bills for the past two years to identify inaccuracies and ensure the appropriate rate structure is applied.Current rate schedules and alternative schedules that are appropriate for a particular use or facility type to ensure the best rate.Contact information for all water and wastewater utilities.Utility information should include the following for potable and nonpotable water:
Determine the marginal per-unit cost of water and sewer service.This step involves collecting water and cost data and determining a baseline that will be used to calculate cost savings and determine overall water reduction potential associated with water-efficiency opportunities.Īt the facility level, this task includes the following substeps:
Understanding the current water uses and costs is essential to a comprehensive plan.
