HydroPoint Data Systems, a Petaluma Calif. maker of water management systems for green areas, has raised $19 million more in a third round of funding.

This brings the company’s total funding to $36 million.

The latest round was led by RockPort Capital Partners, with support from Chrysalix Energy Venture Capital. Both invest in clean technology and energy related companies. Additional investors included Firelake Strategic Technology Fund, Monitor Ventures, Shea Ventures and The Toro Company.

From the company’s statement:

Nineteen percent of California’s electricity and 30 percent of its natural gas are consumed in meeting the state’s water needs, according to the California Energy Commission. The billions of gallons of water WeatherTRAK customers will conserve in 2007 will help relieve dependence on the carbon-based fuels that contribute to global warming. Further, the WeatherTRAK solution protects waterways by virtually eliminating the flow of fertilizers, pesticides and other contaminants from overwatered landscapes.
