Essential Rainwater Harvesting
A guide to home-scale system design
Water is a crucial resource increasingly under stress. Yet rainfall, even in arid climates, can make up a sizable portion of any home, acreage, or farm’s water requirements if harvested and utilized with care. The key is high-quality site-specific design and sensible maintenance.
Essential Rainwater Harvesting is a comprehensive manual for designing, building, and maintaining water harvesting systems for the warm and cold climates of the world.
Presenting design considerations and approaches for the most common household rainwater supply scenarios – primary, supplemental, and off-grid supply – this step-by-step approach covers:
- Planning for full-property water security
- Guidance on navigating regulatory requirements
- Templates for building your own spreadsheet-based calculation tool
- Site-specific planning and spatial layout
- Materials and component design and selection
- System maintenance and upkeep.
Accurate, precise, and detailed…buy one for yourself and it will be useful for all future generations.
