Our Waters / Imagine A Day Without Water

NOAA defines a watershed as a land area that channels rainfall to outflow points. When it rains in West Palm Beach, a few different things happen to the rainfall. In the western regions of the city around the Grassy Waters Preserve, rainfall collects in the wetlands, which absorb water like a sponge. The Grassy Waters Preserve is a 23-square-mile wetland ecosystem and the City's primary source of drinking water. When you turn on the tap, you get water from the Preserve conveyed downtown to our water treatment plant, which is treated and distributed to our customers. Rainfall in the City's developed areas collects in ponds and flows from waterproof, or water-resistant, surfaces into storm drains and inlets, eventually making its way into the City's stormwater system. The City's municipal separate storm sewer system helps provide flood control by collecting and conveying water from rain events in a series of canals and lakes. Everyone living in our watershed impacts its health. Read on below to learn how you can help protect our watershed! Water, a seemingly unending resource, plays a significant role in our lives, yet the infrastructure needed to maintain access to our homes and businesses is often out of sight and, therefore, out of mind. You wake up, shower, make coffee, clean your car, feed your family, flush the toilet, wash your laundry. But have you thought about where your water comes from or where your wastewater goes? What would a day be like without water? Imagine a Day Without Water 2022 is the eighth annual day to raise awareness and educate America about the value of water. On October 20th, we Imagine a Day Without Water. It's a day to pause and notice how water systems impact our lives and communities and commit to ensuring a sustainable water future for generations to come.

   • Turn on the tap, and clean water will flow out. Flush the toilet, and dirty water will go away. • Help eradicate viruses are eradicated with soap, water, and two rounds of the Happy Birthday song.

   • When you have reliable water service, you don't have to think twice about the infrastructure that brings water to your home or business and safely returns it to the environment—but we all should.

   • The reality is that America's water infrastructure is deteriorating as it ages—and there are even communities around the country that have never had access to infrastructure in the first place.

   • On Imagine a Day Without Water, we ask everyone to consider their day if they couldn't turn on the tap and get clean drinking water or if they flushed the toilet and wastewater didn't go anywhere. What would that day be like?

Protect our Watershed by Saving Water

When you use tap water, you contribute to the demand on our local water source, the Grassy Waters Preserve. The city carefully manages this natural resource to balance the ecosystem's needs while ensuring our water supply. Reducing your water consumption can reduce the burden on this precious resource, protect our watershed, and save you money! Check out the Office of Sustainability's Water Conservation Programs to learn how to save water! Learn more about the primary source of our water, the Grassy Waters Preserve.

Prevent Pollution from entering Our Watershed

Discharging pollutants and debris into the stormwater system can directly impact local environmental and public health. There are many ways pollutants can enter a watershed and make their way to local bodies of water. Chemicals used for fertilizer, improperly disposed yard trimmings, and roadside litter can potentially enter the stormwater system and become pollution. It's essential to know how your actions impact the local environment. Check out stormwaterandme.org to learn how you can help keep pollution out of our waters!
