Make one using 1. Describe the Situation Start by introducing the problem: the need for effective water resource management in the Philippines. Present two alternatives: Alternative 1: Installing a Rainwater Harvesting System. Alternative 2: Constructing a Deep Well System. 2. Cite an Example for Comparison Alternative 1: Rainwater Harvesting System Initial Cost: Php 50,000 Annual Maintenance: Php 5,000 Lifespan: 20 years Alternative 2: Deep Well System Initial Cost: Php 120,000 Annual Maintenance: Php 8,000 Lifespan: 30 years Compute the Analysis Cash Flow Calculation Calculate the total cost for each alternative over the given lifespan, considering maintenance. Engineering Economic Model Analysis Net Present Value (NPV) Use NPV to compare alternatives, assuming a 5% interest rate. Calculate IRR for each system to evaluate profitability. Financial Strategies and Tax Laws Discuss potential tax incentives for sustainable systems and available financing options. Consider Noneconomic Attributes Environmental Impact: Rainwater harvesting is more eco-friendly. Reliability: Deep wells provide a stable water supply during dry seasons. 3. Decide on the Best Option Conclusion: Based on NPV and IRR calculations, alongside noneconomic attributes, determine which option is preferable. Discuss why the chosen alternative is the best choice economically and environment. Show solution and explain
