Interested in learning how your consumption impacts the amount water bill. Below is a rate calculator for a residential consumer in a single family home.
The City of Lake Oswego has a tiered water billing structure. This means that as your water consumption reaches higher amounts, the water gets more expensive. A tiered water billing structure was adopted as a way to encourage conservation of a precious resources - water. In entering usage, a residential consumer that lives in a single family home can see how a bill is impacted by consumption that is in Tier 1, Tier 2 and Tier 3 levels.
CCF must be a number
Example - Impact of Tier 3 Usage vs Fixed Rate Changes Over Time
The water bill is calculated by both a fixed rate and a variable rate based on consumption. The costs for consumption are tiered, meaning water gets more expensive as more is consumed. Here is how consumption and the tiered rate impact the water bill:
- The typical consumer is a single family home that consumes 19.6 ccf (20 ccf with 2% conservation savings) or 14,660 gallons of water per bill. The typical consumer has no water usage in Tier 3 and only 3.6 ccf in Tier 2. The typical consumer has a water bill (fixed and variable based on usage) of $85 (rounded).
- If a household uses 69 ccf, their bill is going to be about $247 dollars higher than a typical user. With $210 of their bill being from Tier 3 water consumption levels.
If someone has consumed consistently, the increase in cost of Tier 3 water will be more noticeable than increase in the fixed rate.
In 2009, 37 ccf in Tier 3 cost $101. In 2012 it costs $210.
- In 2009, the Tier 3 rate per ccf was $2.74 per ccf.
- The current Tier 3 rate is $5.67 per ccf.
- The fixed portion of the bill has gone up $13 since 2009.
- In 2009, 37 ccf in Tier 3 cost $101. In 2012 it costs $210.
|Bi- Monthly Consumption Level||Cost Per 100 Cubic Feet (CCF)|
|Tier 1: 0-16 ccf||$2.11/ccf|
|Tier 2: 17-32 ccf||$3.02/ccf|
|Tier 3: over 33 ccf monthly||$5.67/ccf|
