Across the United States, affordable housing developers are facing a new water reality. Water is becoming scarcer while demand and costs rise. Water is a volatile, high-cost budget line item, draining billions from an industry already operating on razor-thin margins.
While developers can’t control the price per gallon, they can control water use volatility. Doing so requires letting go of a misconception: that tenant behavior is the primary driver of high water bills and direct billing will solve the problem. In reality, invisible leaks are the primary driver of high, unpredictable water costs. Unit-level visibility, real-time alerts, diagnosis and automated work orders stop the problem at its source.
Water: Essential, Expensive, and Often Overlooked
Water is fundamental to daily life, yet it has historically been treated as an afterthought in operating budgets and underwriting models. That approach no longer works.
Nationwide, over the past decade, water and sewer rates have risen 2.5 times faster than inflation. As in other parts of the country, water scarcity is a significant issue in Texas as municipalities struggle to maintain aging infrastructure amid rising demand. The result is rising costs that are passed directly to property owners.
Despite this shift, many affordable housing budgets still assume water is stable and inexpensive. The data tells a very different story.
The $5.8 Billion Leak You Can’t See
More than half of all water used in affordable housing is wasted through invisible leaks from running toilets, failing water heaters, and plumbing fixtures in disrepair. Even new and low-flow fixtures eventually leak.
Industry-wide, these hidden losses amount to 390 billion gallons and $5.8 billion every year – enough money to fund thousands of new affordable housing units annually. Because residents rarely notice leaks and maintenance teams aren’t alerted in real time, problems often go undetected for weeks or months, until an astronomical bill arrives 30–60 days too late. Even then property managers and maintenance teams likely can’t identify the leak location.
These leaks don’t just waste water; they undermine underwriting. Anticipated financial performance, reserves, and debt coverage ratios all rely on predictable utility performance. When water costs are wrong, financial planning breaks down.
Why Traditional Underwriting Falls Short
Most underwriting models assume water use is stable and comparable across properties. In reality, two identical buildings can have drastically different water costs due to invisible leaks. With each water utility using unique pricing structures, accurate forecasting becomes nearly impossible without real data. For a deeper dive into how developers, lenders, and investors can turn water efficiency into stronger NOI, better financing outcomes, and long-term portfolio performance, see whitepaper here.
Data Changes Everything – A Texas Based Case Study
Real-time monitoring and leak detection technology now make it possible to measure water use at the unit level and flag anomalies as they occur. ION’s End-to-End Water Management system turns water from an uncontrollable expense into a manageable one, providing visibility, savings, and control.
Like many affordable housing developers, Pivotal’s Reserve at Quebec property in Ft. Worth was struggling to bring its finances in line. Water use and costs were high, but there was no visibility into why. By implementing its End-to-End Water Management system, ION was able to help Pivotal pinpoint fixtures that needed repair, and was able to quickly decrease water consumption by 60%. Reserve at Quebec now operates at a near optimal water use level, with stabilized water costs and annualized savings of an estimated $275,000. See case study here.
How did ION and Pivotal do it? Together. Maintenance teams now receive immediate alerts from ION on location and volume of invisible leaks. Pivotal Asset Managers gain insight into trends and executives have verifiable data, enabling stabilized performance, and getting their costs under control.
According to Brad Weeter, Senior Vice President and Controller at Pivotal, “ION was a true partner for us at a time when we needed immediate visibility and measurable results. Their End-to-End Water Management solution allowed us to quickly identify waste, reduce consumption by 60%, and meaningfully lower operating costs—without requiring upfront capital. The success at Reserve at Quebec reinforced the value ION brings, and we look forward to continuing our partnership across additional properties in our portfolio.”
A Proven, Proactive Approach
Like Pivotal, developers using ION’s End-to-End Water Management system consistently reduce water use by up to 60%, improve NOI, strengthen cash flow, create more reliable underwriting, and access financing that rewards efficiency.
Rewriting the Role of Water
Managing water is no longer optional. Daily monitoring and action as part of standard operations allows affordable housing developers to reclaim wasted dollars, protect assets, and build more resilient communities.
At a time when Texas faces increasing water and operating costs and a severe housing shortage, controlling water costs isn’t just good business, it’s essential to keeping affordable housing viable where it’s needed most.
