The Surprising Reason Your Shower May Lose Pressure

Picture this:
It's early morning, you're rushing to get ready, you hop in the shower and instead of the strong spray you expected, you get… a dribble. You tilt your head back, covered in shampoo, waiting for the pressure to pick up. It doesn't. And yet. Somewhere, just down the street, someone's lawn is enjoying a perfect, steady irrigation cycle.

You both have water. But at that moment, their sprinklers are getting all the pressure.

This little moment tells a much bigger story about how water moves through our city every day, and how our collective habits shape the experience for everyone else on the system.

This is why Metro Water Services is asking customers with automatic irrigation systems to help reduce early - morning pressure drops by running sprinklers earlier and on staggered schedules.

How Our Routines Create Predictable Surges

Across Metro Water's service area, customer usage follows a consistent pattern.

In cooler months, most households use water during the day by doing normal everyday tasks. Washing dishes, taking showers, doing laundry, to just name a few. There's a bump in usage in the morning as people get ready for work and school, then it slowly tapers off.

But during the warmer months?
That pattern shifts dramatically.

In summer, there is an exponential increase of water demand because of irrigation systems. While indoor water use peaks around the time you're getting ready (that 7 -9 a.m. window), irrigation tends to kick on even earlier. In many neighborhoods, sprinklers start firing between 4-5 a.m., continuing right through the hours when families are getting ready for their day.

So, when your neighbors' irrigation is running at full blast before sunrise and everyone's faucets turn on at 7 a.m., that's when the system feels the squeeze. Water moves faster through the pipes, friction builds, and pressure drops. Higher elevations feel it the most and may be greeted with a dribbly sink or slow-moving shower water.

Why Certain Days Feel Worse Than Others

You might notice some mornings are worse than others, and there's a distinct reason for this. Irrigation demand tends to spike on the same days each week. Monday, Wednesday, and Friday are consistently the highest demand mornings across the system. Reservoir levels drop quickly on those days as thousands of sprinklers activate around the same time.

By comparison, Tuesdays and Thursdays seem "calmer". Not because people are showering less, but simply because fewer irrigation systems are running all at once.

The Nerd Part: Numbers Don't Lie

To help visualize how customer behavior shapes our water system, we're sharing two sets of graphs. One shows water usage patterns and the other shows the pressure impacts that result from those patterns.
