Step 1: Identify the original amount of water used, which is 5000 liters.
Step 2: Calculate 20% of 5000 liters. To do this, multiply 5000 by 0.20 (which is the decimal form of 20%).
Step 3: 5000 multiplied by 0.20 equals 1000 liters. This is the amount of water reduced.
Step 4: Subtract the reduced amount (1000 liters) from the original amount (5000 liters).
Step 5: 5000 liters minus 1000 liters equals 4000 liters. This is the new amount of water used after the reduction.
