Basic Concept (network)

Basic Concept (bend roofing) Use gravity to reduce sitting water

Cheaper solution

Roofing Materials Aluminum Stainless Steel Plastic sheets Plastic tarp Scrap metal

Water filtration Boiling Basic Iodine solution First need water filter set (General Ecology) ($200)

Mosquitoes Gutter guards prevent minimize mosquitoes breeding Mosquitoes spray First Flush Water Diverter
