  • Dominican Republic controls algal blooms in 7km²2.7mi² reservoir

About the entity

LG Sonic
LG Sonic products provide an environmentally friendly solution to effectively control algae and biofouling in lakes, reservoirs, treatment plants, and other applications.

After dealing with algal blooms for years, Empresa de Generación Hidroeléctrica Dominicana (EGEHID) installed multiple MPC-Buoy systems to cover the 7km²/2.7mi² Valdesia reservoir earlier this year. Two months after the start of the project, the results have already exceeded the set targets.

Recovering the country’s most important water source

With an area of ​​7 km² (1739.79 acres), the Valdesia reservoir is the main drinking water supply for the population of the Dominican Republic’s capital Santa Domingo and its provinces. Through the aqueduct, Valdesia supplies Santo Domingo with a contribution of 7 m3/sec of drinking water. This hydroelectric plant therefore contributes significantly to the country, both in energy production, human consumption and agriculture. The Valdesia reservoir can store 137.54 million³ meters of water and is used to produce 52,750,000 KWh per year of electricity.

Chemicals were not the solution

Algal bloom treatment in a water surface as large as the Valdesia reservoir proved challenging for EGEHID. The option to use chemical treatment was quickly eliminated. It would be impossible in terms of budget and operations to dose the entire reservoir multiple times a year with chemicals. It was also important to not cause any harm to the environment by using potentially harmful chemicals. This led EGEHID, in their search for an environmentally friendly solution, to the MPC-Buoy.

Monitoring and treatment

Choosing MPC-Buoy has allowed EGEHID to monitor important algae and water parameters in the entire water surface of the Valdesia reservoir. The collected data is delivered in real time to a web-based software, allowing water quality specialists from LG Sonic to manage algal blooms from their headquarters, 10.000 kilometers away in the Netherlands.
