What a restoration costs

The target bands

• The N1

  For ponds to a quarter acre: backyard, garden, and farm ponds

  $3,900-5,900target

• The N2

  For golf, HOA, and community ponds to five acre-feet

  $11,900-15,900target

• The N3

  For lakes of 5-20 acres, including deep, stratified water

  $28,000-42,000target

• The N4

  For working lagoons of 1-10 acres carrying high organic loads

  $55,000-85,000target

Every figure marked "target" is an engineering target for units now in build. Targets are published so you can plan, not to impress you; they can move during production, and the measured value replaces each one when units ship. Changes are logged where the number lives.

Each band covers the unit itself. Installation and Stewardship price with the site, in the proposal, because a hundred feet of trench or a barge mount is real money and pretending otherwise is how teaser pricing works. The proposal itemizes all of it before you commit to anything.

The four factors

• Water volume. Surface area and depth size the unit. A half-acre garden pond and a twelve-acre irrigation reservoir are different machines.
• Starting condition. A pond with years of accumulated organic load asks more of the system in season one than one that's merely stratified.
• The site. Power at the shore, distance from cabinet to water, and access for service all move the installation cost.
• The service. Stewardship (visits, calibration, the weekly record) is an ongoing engagement, priced as one, not a hidden line that appears after the hardware.

The comparison that matters

If you treat chemically today, you already have a water budget: the algaecide line, every year, forever, buying the same month of suppression each time. A restoration is a different shape of spend: equipment plus service, aimed at an end state where the pond holds its own conditions. When you compare quotes, compare a year of each, then compare year three. Ask us in writing for both of our numbers when yours are on the table; ask your chemical supplier what year three looks like with them.

What the market publishes

Commercial nanobubble equipment in the United States is sold almost entirely by quote, so the only public prices the category has produced are the ones that pass through public records. We cite them as documented purchase orders and council items, nothing more:

• A Florida city council approved a sole-source contract not to exceed $121,800 for an eight-month trailer-mounted nanobubble pilot at a city marina (Titusville, November 2025).
• A California city bought two lake-scale units for about $1.7 million in sale and installation, plus roughly $230,000 in related services (Lake Elsinore, Los Angeles Business Journal).

Those installs and ours are not like-for-like, and we can't know what any vendor would quote for your water. The numbers are here because a buyer deserves to know the shape of the market before requesting quotes, including ours.

At the other end, fountains and diffused aerators run roughly $500-8,000 and are genuinely cheaper than any N-Series unit. They treat the surface, and the problems on our map form at the bottom; the full comparison, concessions included, is at nanobubbles vs aeration.

How these numbers firm up

When the first installations price out, measured ranges by water size replace the target bands on this page, and the case files carry their budget shape the way they carry their oxygen curves.

If cost is the deciding question for you right now, say so in the assessment. You'll get the current answer for your water's size in writing, not a callback script.
