Your Diagnosis
sprinkler The Summer Irrigation Spike
Because SCWA bills quarterly, a bill arriving in October often reflects your heavy watering from July and August. A standard sprinkler system uses roughly 15 gallons of water per minute. Running a 4-zone system for just 30 minutes a day can add over 15,000 gallons to your bill.
update The "Catch-Up" Bill
If your previous bills were estimated or showed zero usage, your meter's transmitter may have lost battery power. During that time, you were only charged the minimum base rate. This new bill is a "catch-up" bill—it represents the actual water you used over several months that you weren't previously billed for.
water_damage The Silent Leak
Running toilets are the most common cause of unexplained high bills. A worn-out rubber flapper in the toilet tank can silently waste thousands of gallons of water a month, running straight down the drain without ever spilling on the floor.
pool The Swimming Pool Fill
A standard swimming pool takes 15,000 to 30,000 gallons of water to fill completely, and even topping off a pool throughout the summer due to evaporation can add thousands of gallons to your bill.
group_add The Houseguest Spike
Just one extra person taking a 10-minute daily shower adds roughly 1,500 gallons to your bill over a month. Combined with extra laundry and flushing, a full house significantly impacts your total usage.
yard The Landscaping Spike
Laying new grass seed, sod, or landscaping requires heavy watering to establish. This temporary increase explains the spike in your bill.
plumbing The Plumbing Repair
Plumbing repairs often involve draining and flushing lines. This extra water usage explains a temporary bill increase.

Since your bill wasn't impacted by summer watering, catch-up readings, obvious leaks, or major household changes, there may be a hidden issue like an underground service line leak.
