Water flows through every aspect of our daily lives, yet most of us barely think about where it comes from or where it goes after it disappears down the drain. In the debut episode of Clearstory, This Old House host Kevin O’Connor sits down with author Charles Fishman, whose book “The Big Thirst” challenges everything we think we know about water. From the sprinklers of Las Vegas to the wetlands of Orlando, the episode reveals a surprising truth: water is the ultimate recyclable, and we are standing at the threshold of a revolution in how we use it. For homeowners wondering about their own water quality, understanding whether a water softener improves drinking water is just one piece of a much larger puzzle about how we source, treat, and respect our most vital resource.
The Big Thirst: Understanding Our Relationship with Water
Charles Fishman’s research reveals a central paradox: water is the most essential substance on earth, yet we treat it as though it is nearly worthless. We pay more for bottled soft drinks than for tap water, and most of us have no idea how much water it takes to produce the food we eat, the clothes we wear, or the electronics we depend on. Fishman argues that the real water crisis is not one of scarcity but of management. The Clearstory episode on water as the ultimate recyclable dives deep into why our current approach is unsustainable and what a better future could look like.
The True Cost of Cheap Water
One of Fishman’s most provocative points is that water is too cheap. The average American household pays just pennies per gallon for municipal water. That low price masks the enormous infrastructure required to deliver clean water and treat wastewater. When water is cheap, there is little financial incentive to conserve, repair leaks, or invest in recycling technologies. The result is a system where millions of gallons of treated drinking water are used to water lawns and flush toilets, while the same water could serve multiple purposes if we designed our systems differently.
The Hidden Water in Everyday Products
Another key insight is the concept of virtual water, the hidden water embedded in the products we consume:
- A single pound of rice requires roughly 450 gallons of water to grow.
- A cotton t-shirt consumes about 700 gallons of water in its production cycle.
- One smartphone requires nearly 3,200 gallons when factoring in mining, manufacturing, and assembly.
- A quarter pound hamburger patty represents about 460 gallons of virtual water for the grain and water the cattle consumed.
When we think about water conservation only in terms of shorter showers, we miss the bigger picture. Our most significant water decisions happen at the grocery store and the clothing rack, not just at the bathroom sink.
Cities Leading the Water Conservation Revolution
Two cities stand out as models of water conservation at scale: Las Vegas and Orlando. Las Vegas sits in the Mojave Desert with less than four inches of rain per year, while Orlando lies in subtropical Florida with abundant rainfall. Yet both have emerged as national leaders, proving that geography is not destiny when it comes to water management.
Las Vegas: Making Every Drop Count
The Las Vegas Valley Water District has implemented some of the most aggressive conservation programs in the country. The city has banned grass that nobody walks on, paying homeowners to replace ornamental turf with desert landscaping. Since 2002, the metro area has removed 200 million square feet of grass while adding 800,000 new residents. Despite the population growth, total water use has actually declined. Las Vegas also runs one of the most advanced water recycling programs in the nation, treating nearly every drop of indoor water use and returning it to Lake Mead. For homeowners looking to apply similar principles at home, building smart storage solutions like an ultimate built-in custom library wall can free up space for water-saving equipment installations.
Orlando: Protecting the Aquifer
Orlando faces a different challenge: protecting the Floridan Aquifer, one of the most productive groundwater sources in the world. Rapid population growth has drawn water out faster than natural recharge can replace it. The city has responded by investing heavily in reclaimed water infrastructure, providing treated wastewater to hundreds of communities for irrigation. New developments are increasingly required to connect to reclaimed water systems, and retrofitting older neighborhoods has become a priority. The combination of growth and diminishing supply has forced the kind of innovation Fishman argues we need nationwide.
Solving Water Mysteries in the Modern Home
The Clearstory episode also features This Old House master plumber Richard Trethewey, who solves a water mystery inside a typical home. Trethewey has spent decades helping homeowners understand their plumbing systems, and his segment highlights how the water system in your home is more complex than you realize.
Common Household Water Issues
- Discolored water. Brown or yellow water typically indicates rust or sediment in the pipes. It may be harmless but can signal corrosion needing attention before leaks develop.
- Low water pressure. This can result from mineral buildup inside pipes, a faulty pressure regulator, or corroded galvanized pipes in older homes.
- Water hammer. That banging sound when you turn off a faucet is caused by pressure waves in the pipes. Air chambers or water hammer arrestors solve the problem without major work.
- Cloudy water. Air bubbles are the usual cause and clear within seconds. Persistent cloudiness may indicate high dissolved solids that a treatment system can address.
Trethewey emphasizes that a well-maintained plumbing system is the foundation of any conservation effort. Leaks alone waste an estimated one trillion gallons per year in the United States. A slow drip from a single faucet can waste more than 3,000 gallons annually. Fixing those leaks is the most cost effective step any homeowner can take, and having the right equipment, such as a tool tote built from scrap plywood, makes plumbing repairs far more manageable.
Water Heating and Efficiency
Water heating accounts for roughly 18 percent of a typical home’s energy use. Every gallon of hot water saved is energy saved. Modern tankless water heaters and heat pump water heaters can dramatically reduce both water and energy consumption. An electric hot water setup designed for maximum efficiency can pay for itself within a few years while delivering endless hot water on demand.
| Water Heater Type | UEF Rating | Lifespan | Annual Energy Cost | Best For |
|---|---|---|---|---|
| Conventional Storage Tank | 0.60 – 0.75 | 10 – 15 years | $400 – $600 | Lower upfront cost |
| Tankless (On Demand) | 0.82 – 0.94 | 20+ years | $250 – $400 | Endless hot water, space saving |
| Heat Pump (Hybrid) | 2.00 – 3.45 | 10 – 15 years | $150 – $250 | Highest efficiency in warm climates |
| Solar Water Heater | 1.00 – 2.00 | 20+ years | $50 – $150 | Sunny regions, long term investment |
Practical Steps for Home Water Recycling
The revolution Fishman calls for does not have to wait for municipal upgrades. Homeowners can take meaningful steps right now to reduce waste and start recycling water at the household level.
Greywater Systems
Greywater from bathroom sinks, showers, and washing machines can be safely reused for landscape irrigation with minimal treatment. A properly installed system can reduce household water consumption by 30 to 40 percent. Key components include a three way diverter valve, coarse filtration, subsurface drip irrigation lines, and mulch basins for safe percolation.
Rainwater Harvesting
Rainwater harvesting is the oldest form of residential water recycling. A typical 1,000 square foot roof can collect roughly 600 gallons from a single inch of rainfall. Modern systems include first flush diverters, leaf screens, and UV filtration for indoor use. Many homeowners pair rainwater harvesting with greywater recycling to create a comprehensive home water system.
Smart Fixtures and Better Habits
Smart irrigation controllers adjust watering schedules based on local weather data. High efficiency faucets and showerheads use less than half the water of standard models without sacrificing performance. Dual flush toilets give homeowners a choice between full and reduced flushes. These fixtures pay for themselves within a few years. Behavioral shifts matter too: running full loads, fixing leaks promptly, using a broom instead of a hose, and watering in the early morning all add up to significant savings.
As the Clearstory episode makes clear, the water revolution is ultimately a mindset shift. We have to stop treating water as an infinite resource and start treating it as the precious, recyclable substance it has always been. Every project around the house is an opportunity to rethink your relationship with water. Even something as practical as using a deck demolition tool for efficient tear down during a renovation can be part of a larger approach that prioritizes resource conservation and waste reduction.
The message from Charles Fishman, Richard Trethewey, and the communities of Las Vegas and Orlando is consistent: water is the ultimate recyclable, and the technology to use it wisely already exists. What remains is the collective will to put that knowledge into practice, one home and one mindset shift at a time.
