# Water restoration for municipalities

A closed beach is a public event, and every decision about the lake has to be defensible in front of council and residents. What you need is prevention that holds and paperwork that explains itself.

## The problems we see on your water

## What Alchemal installs and takes responsibility for

Blooms close beaches, and oxygen is how you keep them open. Our systems raise and hold dissolved oxygen throughout the lake, which removes the conditions harmful algal blooms depend on. There are no chemical applications to permit or post, no re-treatment cycle, and the monthly data report can go in front of council exactly as we send it to you. Where a state requires an equipment permit for natural waters, we say so up front and carry the application work; the current state of play is at [permits and regulators](https://alchemal.com/technology/permits/).

For lakes of 5-20 acres the system is the [N3](https://alchemal.com/technology/n-series/n3/): staged output, single or three-phase power, shore or barge mounting, and the electrical documentation procurement asks for. Every installation is instrumented from day one, so the record that defends the budget is the same record that runs the restoration. The [methodology](https://alchemal.com/technology/how-we-measure/) is published, and [Stewardship](https://alchemal.com/stewardship/) carries service, calibration, and seasonal reporting without adding load to public works.

## Proof from municipalities

The first installations for this audience are being instrumented now, and their case files publish when the record is worth reading. The [methodology](https://alchemal.com/technology/how-we-measure/) is already public: what we record, how we calibrate, and how we report what didn't move.

## From your first note to the assessment

1. You describe the water. A specialist reads it, replies in writing, and says whether an assessment makes sense.
2. Your water goes on the schedule. The first assessments and installations are being scheduled now; requests are answered in the order they arrive.
3. The assessment puts a baseline on paper: dissolved oxygen top to bottom, clarity, the condition of the sediment, and a plan with a prediction attached. If oxygenation isn't the right fix, the report says so.

## Questions your procurement will ask

**Does this require permits or public postings?**

No chemical permits or postings: nothing is applied to the water, so there is no treatment calendar to defend. Equipment is a separate question. Some states require an aeration or shoreline permit for machinery in natural waters, and at least one is reviewing nanobubble systems specifically. We track the rules by state, prepare the application materials as part of the engagement, and keep a plain public account on our permits page.

**What does the reporting look like?**

A monthly data report against the measured baseline: dissolved oxygen, clarity, and the season's trajectory, written to be forwarded to council or a board exactly as we send it.

**What about an active harmful algal bloom?**

Safety first, always: keep people and pets out, notify your state environmental agency, and let testing confirm or rule out toxicity. We are not an emergency response. Restoration is how next summer becomes different.

## Start with a conversation.

Describe the water and a specialist replies in writing, before any commitment. Your water, your numbers.
