Aquatic growth can be a special problem in ponds and in slow-moving water sources in some parts of the country. In extreme cases it may be necessary to drain a pond to control the growth. This will require careful timing and good communications to assure that other water sources are available for emergencies and that the pond will refill without undue delay. Hydrants should be tested with a pumper once a year and backflushed as part of training exercises. Pay particular attention to safety-related features, such as warning signs and bumper guards.
Appearance is another consideration.
Grass and vegetation will need to be kept trimmed. Repainting will be needed periodically. Maintaining the grounds around the dry hydrant assures better visibility in an emergency, and it will help keep good relations with the landowner. Records should be kept of all inspections and procedures. Keep the records available with the maps showing the location of all installations.
