Rates & affordability
Your bill has two parts: a fixed monthly charge that keeps the pipes and plants running whether you use water or not, and a charge for the water you actually use. The second part is tiered, so the first few thousand gallons cost the least.

Each block of gallons costs more than the one before it. The reason is not to punish anyone: the first block covers what a household needs to live, and the top block covers the cost of building capacity for the hottest week in July.
| Tier 1: first 3,000 gallons | 1 to 3,000 | $5.30 |
|---|---|---|
| Tier 2: 3,001 to 8,000 gallons | 3,001 to 8,000 | $6.95 |
| Tier 3: 8,001 to 15,000 gallons | 8,001 to 15,000 | $9.20 |
| Tier 4: above 15,000 gallons | 15,001 and up | $12.60 |
Tier 1: first 3,000 gallons
Drinking, cooking, washing, and flushing. This block is priced lowest on purpose: nobody should have to ration the water they need to live.
Tier 2: 3,001 to 8,000 gallons
Ordinary household use above the essentials. Most families land here, and the typical bill is calculated in this block.
Tier 3: 8,001 to 15,000 gallons
Lawns, pools, and long summer irrigation. This is the block that drives the July peak the treatment plants have to be built for.
Tier 4: above 15,000 gallons
Heavy seasonal use. The highest block pays the largest share of the cost of peak-day capacity, which is the fairest place to put it.
The bill for a household using 5,000 gallons a month, from $38.60 in 2016 to $52.30 today.
