(WS-1903) Water Conservation 101: Get Ready, Set, Go

For water efficiency beginners, experienced managers, and all other interested
parties, this workshop will provide an overview of the essential ingredients and steps
involved in developing a successful water conservation plan and program. An
overview of the latest in water-saving technologies, policies, analytical models and
software tools (e.g., AWE Water Conservation Tracking Tool, AWWA Water Audit
software, and EPA WaterSense Water Budget Tool) will be provided along with case
studies and other tips to connect and thrive in the world of water conservation and
efficiency. “How to” steps and topics to be covered will include:

1. Definitions of a Successful Water Conservation Program
2. Water-Saving Goals
3. Data Analytics: Customer and System Water Use Profiles
4. State-Of-The-Art In Water-Saving Measures And Incentives
5. Potential Water Savings, Benefits And Costs
6. Water Conservation Planning-Budget, Staffing, Schedule
7. Program Implementation
8. Program Monitoring and Evaluation
9. Water Conservation Network
10. Southern Nevada Water Authority: Program Overview

(WS-1909) Benefit-Cost Analysis

Benefit-Cost analysis has been used for years to prioritize water conservation measures. Individual water conservation measures are considered to be cost-effective when benefits exceed costs. Once individual measures have been found to be cost-effective, they can be combined into an overall water conservation program. Benefit-Cost analysis depends on accurate forecasts of conservation measure water savings, costs, and benefits. Benefits and costs are normally compared in a present worth analysis.

(a) Workshop Objective
Provide an understanding of how to prepare a cost-benefit analysis of conservation measures and then use the results to select a cost-effective conservation program.

(b) Methodology to be Covered
1. The first step it to characterize the water use for a particular area by making a water use profile. The profile can be a pie diagram showing the percent of the total water use by different types of customers, such as residential, commercial, industrial, etc.
2. Seasonal water use is analyzed to separate indoor and outdoor water use by customer type. From this analysis the conservation potential can be established by comparing local water use with accepted values for any particular end use (such as toilet use in single family homes).
3. Individual conservation measures can be identified to address different types of customers (commercial audits, toilet rebate programs, tiered rate structures). Typically a large list of 50 to 100 conservation measures is screened qualitatively to find the measures worthy of further analysis, such as benefit-cost analysis. The screening process will be demonstrated at this workshop.
4. Next it is important to quantify water savings for each measure. Examples will be provided.
5. Potential benefits that can be attributed to water conservation programs will be explained.
6. Benefit-Cost analysis can be conducted using a variety of computational tools. It is proposed to demonstrate several software available tools. These tools test whether an investment in a particular conservation measure produces more benefits than it costs (on a present value basis).

(c) Workshop Agenda
a. Why do a Benefit-Cost Analysis?
b. How to Define Benefits From Water Efficiency
c. How to Navigate the Maze of New Conservation Measures
d. Proven Techniques to Calculate Water Savings
e. Understanding the Challenges of Benefit-Cost Analysis
f. Forming Innovative Programs of Cost-Effective Measures
g. Examples and Exercises
h. Demonstrate Available Software to Perform Calculations
