Cal Maritime manages water resources to ensure adequate supply, meet or exceed health standards, reduce environmental impact and cost, and conserve and protect natural resources.
Cal Maritime's annual water use is about 46,000 Ccf per year. Water is used in buildings for toilets, showers, and sinks. Dining services uses water in the main dining center and other cafeterias. Water is also used for irrigation.
Cal Maritime has been working with City of Vallejo and Solano County Water Agency to identify water saving opportunities in the campus in indoor and outdoor water use. The following sections describe indoor and exterior water use initiatives:
Indoor water use savings:
A group of four students completed a project to replace existing inefficient toilet bowls, shower heads and sink faucets across the campus with efficient ones. The cost of material and labor to replace inefficient water fixtures will be funded by Solano County Water Agency. The tables below shows the indoor water saving opportunities identified for toilets, urinals, sinks and showerheads.
Outdoor water use savings:
Cal Maritime sustainability and facilities teams worked with Solano County Water Agency and identified opportunities to save water used in irrigation. The primary measures identified were to set appropriate water pressure, minimize over spray, upgrade controllers, and sprinklers. Team is working to implement these measures.
A master irrigation study was conducted and in 2018 and planning work is in progress to achieving xeriscape. Xeriscape is a style of landscape design requiring little or no irrigation or other maintenance, used in arid regions.
Drought-Tolerant Landscaping: Cal Maritime has a continuing effort to identify areas of the campus in which grass can be replaced with drought tolerant landscaping such as California native plants, decomposed granite or rocks, which require minimal to no water.
Upgraded irrigation control system: Cal Maritime is evaluating to installing ET controllers for centrally controlling all the controllers. This system includes an upgraded computer and the purchase of the annual factory technical support to optimize system operation. The program will also connect with a campus weather station and incorporates evapotranspiration, adjusting irrigation needs automatically.
