How It Works

One Visit, From Detection to Repair

EFI scans your covered lagoon or digester from the air and on the ground, samples the gas, checks the cover, and closes the quick fixes, all in a single visit and with no downtime. Everything comes back in one report you can act on.

Scan from the air

A drone flies the full cover with a laser methane sensor and a thermal camera to find and map leaks from above.

Confirm on the ground

A walk-down with a portable methane analyzer pinpoints each source and catches leaks the aerial pass cannot see, plus a spot gas sample and cover thickness readings.

Fix on the spot

EFI closes the quick repairs during the visit: reseal lifted seams, re-seat condensate traps, re-boot penetrations. Compliance restored, gas kept in the system.

Report

You get one clear report and the annotated inspection video: what we found, what it was costing, what we fixed, and what to plan for.

Find It. Fix It.

We Do Not Just Find the Leak. We Close It.

Most inspections hand you a list and leave. EFI carries the crew and the materials to close the quick fixes right there on the visit, reseal a lifted seam, re-seat a condensate trap, re-boot a penetration, so the leak is stopped, not just documented.

Stay Compliant

A located, above-threshold release closed on the same visit keeps you ahead of a reportable event, with a dated record of the fix for the file.

Protect the Value

Every scfm you stop leaking is gas that goes back into your stream instead of into the air. The quick fixes pay for themselves in weeks.

Environmental Stewardship

Methane is a potent greenhouse gas. Stopping it at the source is the fastest, lowest-cost climate action a site can take, and the record proves you took it.

The Deliverable

One Report, Three Answers

Not a stack of raw data. A clear report, the way you get a service report when you bring a vehicle in, that tells you what is wrong, what we fixed, what it costs, and what breaks next.

Findings and Fixes

Every located methane release, ranked and tied to a spot on your site, with the quick fixes closed on the visit and any larger repairs scoped. The ground walk catches what the air misses, and the air catches what is invisible from the ground.

Value at Risk

The methane leaving your site, translated into lost gas value and environmental load, so every finding has a number next to it and the fix pays for itself.

Outlook

Cover condition and the areas to watch, from thermal stress to spot thickness readings, so a repair stays a planned repair instead of an unplanned shutdown.

This is what you receive after a visit: located methane releases with what was fixed on site and what is recommended, the value at risk from the gas that is escaping, and an outlook on cover condition, in the clear service-report format above.

The figures are illustrative. Your report carries your site's real readings.

Who It Is For

Built for the Sites We Know Best

Covered Lagoons

Find lifted seams and fugitive methane on covered anaerobic lagoons before they become a reportable release or a lost-gas problem.

Anaerobic Digesters

Document methane capture and destruction, check cover condition, and confirm your gas is going where it should.

RNG Sites

Every scfm that leaks is gas that never reaches your end use. The inspection puts a number on it and shows you where it goes.

Any EFI Cover

Whether EFI built the cover or not, the inspection adds an annual record of leaks, value, and cover condition, with the quick fixes handled on the visit.

FAQ

Frequently Asked Questions

An EFI methane inspection finds and maps releases across a covered lagoon or digester two ways: a drone-mounted laser methane sensor and thermal camera scan the full cover from the air, and a ground walk-down with a portable analyzer confirms each source and catches leaks the aerial pass cannot see. On the same visit, EFI pulls a spot gas sample from the collection header to read methane, carbon dioxide, oxygen, and hydrogen sulfide, takes cover thickness readings, and closes the quick fixes on site. The result is a single report that shows where gas is escaping, what it is costing, what was repaired, and which parts of the cover to plan for.

No. The aerial survey is flown while the site operates normally, so there is no downtime. The ground walk-down, gas sample, cover checks, and quick repairs are all done during the same visit without taking the system offline.

The sensor pinpoints and maps methane concentrations as the drone flies a grid, so each release is tied to a real location you can walk to. Leak rates are estimated from the sensor readings and the flight path and are confirmed on site before any repair.

You receive one report with three sections: located methane releases with what was fixed on site and what is recommended, the value at risk from the gas that is escaping, and an outlook on cover condition and the areas to watch. The annotated inspection video comes with every report.

Yes. EFI carries the crew and the materials to close the quick fixes during the same visit: reseal lifted cover seams, re-seat condensate traps, and re-boot degraded penetrations. Stopping a located, above-threshold release on the spot keeps you ahead of a reportable event, keeps the gas in your system, and cuts the methane going to atmosphere. Larger repairs, such as a full seam re-weld or a panel replacement, are scheduled and documented.

Owners and operators of covered lagoons, anaerobic digesters, and RNG sites. EFI already designs and installs these covers, so the inspection adds a full-site view of the sites we know best, whether the cover is one EFI built or not.
