Homebuilders are incorporating advanced water conservation systems directly into their new builds.

Why it matters: Greywater recycling, rainwater harvesting, water-efficient fixtures, and smart leak detection can slash bills and boost sustainability, while adding value to your home.

Here are three ways you can incorporate water conservation systems directly into your new home:

1. Greywater Recycling Systems

How it works: Greywater recycling systems collect used water from showers, sinks, and washing machines and reuse it for irrigation or toilet flushing. By repurposing this water, households reduce the strain on freshwater resources and municipal wastewater treatment systems.

“Whole-house graywater system is one of the most advanced and expensive graywater recycling projects but with the most significant impact for the planet and water bills,” said Justin Cornforth, CEO and owner at Ace Home Co.

Cost: Purchase and installation costs typically average around $2500, though they can be as little as $700 or as much as $20,000, depending on size and complexity.

Annual savings on water bills offering a return on investment within a few years, particularly in areas with high water rates or tiered pricing structures.

2. Rainwater Harvesting for Irrigation

How it works: Rainwater harvesting systems collect and store roof runoff in above-ground barrels or underground cisterns. This water is commonly used for irrigation, pond and fountain filling, and toilet and urinal flushing, reducing reliance on municipal water supplies and easing stormwater runoff.

“Of course, you can’t use this water for drinking or cooking – but these two are the minor water users because we spend most [water] on landscaping, flushing toilets, and watering gardens,” said Cornforth.

Cost: System costs can vary from a few hundred dollars to over $10,000 depending on complexity and storage capacity. In regions with incentive programs or rebates, the financial barrier to adoption is significantly reduced.

3. Water Efficient Fixtures and Leak Detection

How it works: Low-flow toilets, high-efficiency faucets, and water-saving showerheads are now typical in modern builds. These fixtures can reduce household water use by up to 40 percent compared to older counterparts, without compromising performance.

Smart leak detection systems and water monitors further enhance efficiency by identifying leaks or abnormal usage patterns early, preventing water loss and potential property damage.

“If you're serious about saving water at home, the good news is most solutions don’t require much planning, a complete remodel, or construction crew – you can start and finish it today,” Cornforth said.

Cost: “Low-flow showerheads, for example, are one of the easiest upgrades you can make: They cost under $30 at Home Depot, take five minutes to install, and instantly cut your water use without sacrificing pressure,” says Cornforth.

Benefits of Water Conservation Systems in Your Home

Integrated Design Offers Long-Term Gains

Designing homes with conservation in mind from the outset allows for optimal system integration.

Dual plumbing lines can be installed for greywater reuse, roofs can be sloped to direct rainfall into storage systems, and native landscaping can be selected to reduce irrigation needs.

Such integration reduces retrofit costs and improves overall system performance, while also increasing the home’s appeal to environmentally conscious buyers.

Strong Return on Investment

Although some systems require a notable upfront investment, they deliver significant long-term savings through reduced water bills and maintenance costs.

Plus, they can increase property value, access to green home certifications, and eligibility for government incentives.

“These systems require permits, professional installation, and regular upkeep,” Cornforth said. “They don’t make financial sense for everyone, but they do save up to 40% of total household water usage, and are excellent for big families and homes in dry areas with gardens.”

Environmentally, these systems contribute to reduced water demand, lower energy use for water heating and treatment, and decreased environmental impact. In regions facing recurring drought or water restrictions, these homes support both individual resilience and broader resource conservation efforts.

Bottom Line

Water-efficient systems are becoming a standard feature in new residential construction. Designed with both financial and environmental sustainability in mind, these homes offer smarter solutions for the environmentally conscious buyer.
