Level Lume is an ambient conservation device that utilities can deploy to households. No app to install, no behavior change program to run — residents simply glance at a wall fixture that shifts color with their water use.
Start a pilot program →Decades of peer-reviewed research confirm that real-time, always-visible feedback on resource consumption reduces usage by 5–15%. Level Lume applies this principle with modern hardware — no screens, no apps, no learning curve.
Monthly billing statements tell residents what they used — weeks after the fact. Apps require conscious effort to open. Ambient feedback works because it requires zero effort: a glance at a wall fixture communicates usage instantly through color. Green means low. Yellow means moderate. Red means high. Blue signals a leak.
This isn't speculative. The mechanism has been studied since the 1970s energy crisis, and has been validated repeatedly across electricity, gas, and water.
"The effectiveness of feedback on energy consumption." Review for the Environmental Change Institute found that in-home displays reduce consumption by 5–12%, with savings persisting over time. [1]
"Advanced metering initiatives and residential feedback programs." Meta-review of 61 studies across 9 countries found real-time feedback produces average savings of 12%, outperforming enhanced billing (3.8%) and web-based audits (8.4%). [2]
"Feedback on household electricity consumption: A tool for saving energy?" Systematic review of feedback programs finding that frequent, always-visible, appliance-specific feedback produces the strongest conservation effects. [3]
The average household with leaks wastes approximately 10,000 gallons per year. Nationally, easy-to-fix leaks account for nearly 1 trillion gallons wasted annually. [4]
Real-world utility pilot: households receiving real-time water feedback consumed 7.5% less water than non-participants, at a program cost of $450 per acre-foot — significantly below the utility's prior conservation cost of $793/AF. [5]
Utility conservation programs are measured by cost per acre-foot of water saved. Level Lume's one-time hardware cost, amortized over years of sustained savings, is competitive with existing demand-side management programs and significantly cheaper than new supply infrastructure.
Cost per acre-foot saved. Desalination, recycled water, and average conservation program figures from CPUC White Paper on Cost of New Water Sources. Real-time feedback benchmark from Denver Water / Dropcountr pilot program. Level Lume's actual cost per acre-foot will be determined through pilot program measurement. 1 acre-foot = 325,851 gallons.
Level Lume fits into existing utility program structures. Pick the model that works for your district.
Start with 50–200 households. Measure real consumption data against a control group. Build the evidence base for your district before scaling.
Subsidize the device cost for ratepayers. Customer self-installs in 15 minutes — no plumber, no meter modification. Low administrative overhead.
Purchase in bulk and distribute to high-consumption households. Target the top 20% of users where the conservation opportunity is greatest.
When Level Lume detects continuous water flow, the fixture turns blue — an immediate, impossible-to-miss alert. No push notification to ignore, no app to check. Residents see it the moment they walk past.
The average household with leaks wastes approximately 10,000 gallons per year according to the EPA. [4] Early visual detection can significantly reduce that waste by alerting residents before a small leak becomes a large one.
Individual household data stays with the homeowner. Level Lume does not share personally identifiable consumption data with utilities or third parties without explicit consent.
Utilities receive aggregate, anonymized program reports: total program savings, participation rates, average reduction percentages. Enough to evaluate and report on the program — without compromising customer trust.
Individual usage data belongs to the homeowner. Full control, full transparency.
Utilities get program-level metrics: total savings, participation, average reduction.
Built for both California and European privacy regulations from day one.
Consumption data is never sold to third parties. Period.
Water meter integration via Flume. Compatible with most US residential meters.
Flume integration covers most standard US water meters. No meter replacement or modification required.
P1 smart meter integration for electricity, water, and gas. Launching in the Belgian market.
California's AB 1668 and SB 606 set urban indoor water use targets that tighten over time: 47 gallons per person per day as of 2025, dropping to 42 gallons by 2030. [7] The State Water Resources Control Board requires utilities to demonstrate demand management progress. A measurable, scalable behavioral conservation program strengthens your compliance case.
For EU utilities, the Water Framework Directive and national efficiency targets create similar incentives for demand-side reduction tools with documented results.
Conservation programs that rely on apps and dashboards produce what we call active savings: reductions that depend on a user deliberately checking a screen. Active savings work initially — the novelty drives engagement. But over weeks and months, open rates drop, logins decline, and savings erode back toward baseline. Typically, only one person in the household ever engages with the app.
Level Lume produces passive savings. The feedback is always visible, always on, and requires no conscious decision to engage. Every member of the household is exposed — not just the person who installed the app. The fixture is encountered multiple times per day, simply by walking past it. There is no novelty to wear off because the information is environmental, not interactive.
User must open app, read data, decide to act. Engagement peaks at install, then declines. One household member engages. Savings decay as novelty fades.
Information is always visible with zero effort. Every household member is exposed. No login, no notification fatigue. Savings persist because the feedback never stops.
The question for utilities is not whether feedback-based conservation works — the research is clear that it does. The question is how much of that savings curve your program retains over 12, 18, and 24 months. Ambient feedback is designed to maximize persistence. A pilot program will quantify the exact retention curve for your service area.
