Why Smart Water Matters More Than Ever in San Diego

San Diego’s in good shape water-wise this year, even with below-average rainfall. Thanks to long-term investments and a diverse supply strategy, the region has enough water to meet demand through the dry months. The Carlsbad Desalination Plant plays a big role here—producing over 50 million gallons of clean drinking water a day. It’s efficient, eco-conscious, and just received a $19.4 million boost from the federal government to make it even better.

But while the supply is steady, the cost of water is climbing. The San Diego County Water Authority has approved a 14% rate increase for 2025, and the city’s adding a 5.5% pass-through adjustment in May. Most of this comes from rising import costs—and unless something changes, the average household could see their bill jump from $90 to around $145 by 2030.

This is where being proactive pays off. At One Water Systems, we believe every drop should count—especially when you’re paying more for it. Our whole-house filtration system ensures you’re not just getting cleaner, safer water, but also stretching your supply further. It’s all about smart water use, built for whatever the future throws at us.
