WATER PURIFICATION SYSTEM. Water filter systems in office buildings that make water safe to drink.
WATER PURIFICATION SYSTEM. Individual filter systems in community buildings that make water safe to drink. Water testing kits: Have a supply of household kits for testing drinking water quality that you can distribute to the disadvantaged in community. Agreement with neighboring communities: Strong working relationships with nearby communities similar to yours can reinforce support during a disaster. Declaring emergency haying and grazing on CRPs: Ranchers are able to use grass from land enrolled in the Conservation Reserve Program. Drought plan: Drought plan includes mitigation and response strategies for your community.
