Quick Answer
Sewer credits do not directly earn LEED points — a sewer credit is a billing adjustment, while LEED rewards actual reductions in water consumption. But the two programs run on the same infrastructure. The submetering, blowdown control, and consumption documentation required for a sewer credit application are essentially what LEED v4/v4.1 requires under Water Efficiency credits: Cooling Tower Water Use (up to 2 points) and Water Metering. A building that has completed sewer credit metering has typically done 70 to 80 percent of the work for LEED’s water efficiency documentation. The financial logic runs both directions: sewer credits deliver recurring monthly utility savings — often $1,000 to $5,000 for buildings with large cooling loads — while LEED certification adds market value. If you’re installing meters for either program, file for both.
If your building is pursuing LEED certification — or has already achieved it — you might wonder whether your sewer credit program helps with those green building goals. The short answer is that sewer credits themselves don’t directly earn LEED points, but the metering, monitoring, and water management practices required for sewer credits align closely with LEED’s water efficiency requirements. In practice, the two programs reinforce each other powerfully.
How LEED Handles Water Efficiency
LEED v4 and v4.1 award points under the Water Efficiency (WE) category, which is divided into prerequisites and credits. The most relevant for cooling tower operations is WE Credit: Cooling Tower Water Use, which awards up to 2 points for optimizing cooling tower water consumption. Specifically, LEED requires maximizing cycles of concentration and using conductivity controllers to automate blowdown, using non-potable water sources where feasible, and demonstrating a 20 percent or greater reduction in cooling tower water use compared to the baseline calculation.
Additionally, WE Credit: Water Metering requires building-level and subsystem-level water metering — including cooling tower metering — with ongoing data tracking. This is essentially the same metering infrastructure you need for sewer credit applications.
The EPA’s green building standards overview details how programs like LEED incorporate water efficiency requirements that align with federal water conservation goals.
Where the Programs Overlap
The overlap between sewer credit requirements and LEED water efficiency requirements is substantial. Both require dedicated submetering on cooling tower makeup and blowdown lines. Both require documented water consumption data collected over time. Both reward optimizing cycles of concentration — LEED because higher cycles mean less total water consumed, and sewer credits because the utility wants accurate evaporation data. And both benefit from real-time water monitoring that provides the continuous data streams required for documentation.
In practical terms, a building that has installed submeters, optimized its cooling tower chemistry, and documented its water consumption for sewer credit purposes has already completed 70 to 80 percent of the work needed for LEED water efficiency credits.
The Financial Case for Both
Pursuing sewer credits and LEED certification simultaneously creates a compelling financial case. Sewer credits provide immediate, recurring monthly savings on your utility bill — often $1,000 to $5,000 per month for buildings with significant cooling loads. LEED certification provides market value through higher rents, lower vacancy rates, and increased property valuation. Studies cited by the EPA’s WaterSense program show that LEED-certified buildings command rent premiums of 3 to 8 percent and sale price premiums of 10 to 25 percent.
The infrastructure investment — meters, monitoring, and documentation systems — serves both purposes simultaneously. You don’t need separate metering for LEED and sewer credits; the same data feeds both programs.
What Sewer Credits Don’t Do for LEED
To be clear, a sewer credit from your utility is a billing adjustment, not a water conservation measure. LEED’s water efficiency credits focus on reducing actual water consumption — using less water, not just paying less for the water you use. So the sewer credit itself doesn’t earn LEED points. However, the practices that make sewer credits possible — submetering, monitoring, optimizing cycles of concentration, reducing drift — directly support the water reduction goals that LEED does reward.
If your building isn’t yet pursuing sewer credits, the LEED certification process may be the catalyst that gets you there. The metering you install for LEED documentation automatically generates the data you need for sewer credit applications. It would be inefficient to install the meters for LEED and not also file for the utility credits they enable.
Sequencing the Two Programs: What to Do First
If you’re starting from scratch, sequence the work so each dollar does double duty. Start with the metering: install submeters on the cooling tower makeup and blowdown lines, specified to your utility’s accuracy requirements so the same hardware satisfies both the sewer credit application and LEED’s Water Metering credit. Second, optimize cycles of concentration with your water treatment vendor — this reduces total consumption (what LEED rewards) and stabilizes the evaporation data your utility will review.
Third, file the sewer credit application as soon as you have the meter data your utility requires — often just 1 to 3 months of reads. Credits are rarely retroactive, so waiting until the LEED submittal is finished leaves money on the table every month. Finally, fold the same data into your LEED documentation. The monthly meter logs, water balance, and treatment records you assembled for the utility are the core of the WE credit narrative.
Beyond LEED: Benchmarking Ordinances and ESG Reporting
The same meter data has a third life. A growing list of cities requires large commercial buildings to benchmark and report energy and water use annually through ENERGY STAR Portfolio Manager, and investor-driven ESG reporting increasingly asks for water intensity metrics alongside energy. Submetered cooling tower data turns those reports from estimates into defensible numbers — and documented water performance is easier to improve when you can see exactly where the gallons go.
For property managers, this is the strongest version of the pitch to ownership: one metering investment supports a utility bill reduction with a payback often measured in months, LEED water efficiency points, compliance with local benchmarking rules, and cleaner ESG disclosures. Few capital line items under $10,000 touch four value streams at once.

Two Programs, One Infrastructure
Sewer credits and LEED certification are complementary strategies that share the same foundation: accurate water metering, disciplined monitoring, and documented optimization. If you’re pursuing either one, you should be pursuing both. The incremental cost of adding the second program is minimal, and the combined financial and market benefits far exceed what either delivers alone.
