Revive Amatitlan

Non-registered organization or association

Revive Amatitlán is dedicated to reviving lake Amatitlán. Our first step was a 2017 pilot in which thousands of fish were created, fish eggs covered artificial spawning beds and in which 4 meters of sludge was bio-eliminated.

Mission, vision & values


To demonstrate, hyper locally, dock by dock, the mosts cost effective in-situ de-eutrophication and the recovery of the native food web. Every deployment beneath a dock will have clean water with oxygen from top to bottom and will include artificial reef-like spawning beds and grow habitat.


That in-situ de-etrohication is possible world wide. De-eutrophication can happen quickly and affordably.

We value facts, science and evidence

Products, services, and programs


In situ de-eutrophication and wastewater treatment products


In situ de-eutrophication services


We are working on a program with Fundaeco to improve the Playa de Oro at Lake Amatitlan park.

Organizational detail

Number of employees: 
Primary issue(s) / need(s) addressed

The unmet community need is the means to eliminate eutrophication ourselves, in situ, locally, affordably and quickly without depending on upstream solutions / help. Lake Amatitlan, and some other eutrophic waterbodies, can be de-eutrophied in-situ.

Impact, adaptations & objectives

Impact measuring

We will start by de-eutrophying hyper-local areas and there will be an explosion of fishery biomass. we will use underwater and above water cameras, biological surveys and daily harvest surveys to collect and publish impact data

Organizational adaptations:

Organizational adaptation details

Funding model

We are moving towards a model where dock, marina and park owners will pay us to de-eutrophy their water volume creating a wallless sludge less swimming pool. the sludge and algae will subsume into a food web that will be living in artificial reef-like habitat.

Short term objectives


To launch the first in-situ, hyper-local de-eutrophication capabilities in the world.


The impact at first is "hyper-local" and will validate that de-eutrophication is possible.

Long term objectives


The process is based on continually harvesting wild algae in such a way that it subsumes real-time into the food-web living within the artificial reef-like habitats.


To use the de-eutrophication of waterbodies around the world as the electron donor with which to sequester carbon.
