Water restoration for HOAs
The pond is the neighborhood's front page, and the board answers for both its look and its line item. Decisions need to hold up in a meeting and in the water.
The problems we see on your water
What Alchemal installs and takes responsibility for

A community pond fails in public. When it turns green, the calls go to the board, and a monthly-treatment plan means those calls keep coming, at compounding cost. Restoration exits the loop: an N-Series system holds oxygen through the full water column, the conditions stop favoring algae, and the pond’s own biology does the maintaining.
What the board gets is accountability in writing: a measured baseline before any commitment, a plan with its prediction on paper, and Stewardship reporting monthly against it. No chemicals means no postings and nothing to explain at the pool.
Proof from your peers
Our first published case files for this audience are being measured now. Every installation is instrumented from day one, and our methodology shows what we record and how we report it.
What an assessment involves
- A specialist visits your site and profiles the water: dissolved oxygen top to bottom, clarity, and the condition of the sediment.
- You get a written baseline: the numbers on day 0, dated, in plain language.
- We propose a plan with a prediction attached: what should move, by when, and how we'll both know. If oxygenation isn't the right fix, the report says so.
Questions your procurement will ask
How does the board evaluate this against the current vendor?
On the record. The assessment produces a measured baseline and a written plan with a prediction attached: what should move, by when. Compare that against invoices for the current treatment calendar and what the pond looks like in year three under each.
What goes in front of the residents?
The monthly report, as-is. It's written in plain language against the baseline, with the measurements attached. It's the same document we use to hold ourselves to the plan.
Is there a long contract?
Stewardship is transparent about its costs, and success looks like less intervention over time. We can show that, because we measure. Terms come with the written plan after the assessment.

A water assessment puts a baseline on paper before any commitment. Your water, your numbers.
