Rainwater Harvesting: A Practical Guide to Collecting, Storing, and Using Rainwater at Home

By Talor Press

Every time it rains, thousands of gallons fall on a roof you already own and run to a storm drain. This guide shows a homeowner how to catch part of that water, store it, and put it to work, starting with the numbers and following the water from the roof to the tap.

Fifty-eight short lessons in seven parts cover:

Foundations and Safety: why harvest, the six parts of every system, ladder, weight and tank safety, rules and permits, the use ladder, and planning a first system.
Rain, Roofs and Numbers: rainfall data, catchment area, yield, losses, garden and indoor demand, mulch and soil, the water budget, sizing storage, and sizing for your climate.
Roofs, Gutters and Collection: roof materials, gutters, guards, downspouts, first-flush diverters, inlet filters, and peak flow with overflow.
Storing the Water: barrels, above-ground tanks and bases, materials, underground cisterns, linked tanks, vents, mosquito proofing, rain gardens, and tank volume.
Water Quality and Treatment: what rainwater picks up, screening, treatment stages, testing, keeping stored water fresh, and why drinking use is different.
Getting the Water Out: gravity feed, pumps, drip irrigation, watering trees, lawns and containers, outdoor uses, indoor non-potable plumbing and cross-connection, and backup supply.
Building and Looking After the System: a one-barrel project, a tank system with first flush, commissioning, maintenance, winter and drought, troubleshooting, costs, and a year-one review.

Every lesson has the same shape: a short explanation, a key-points box, worked examples, a common mistake to watch for, a tip for the tank, and four practice questions with answers. Every lesson carries a drawing of the idea it teaches, 67 figures in all, including a key to the component symbols used in the drawings.

240 practice exercises in twelve sets with full solutions: catchment area, gallons per inch of rain, yield, metric yield, garden demand, days of supply, tank volume, water weight, units to buy, peak flow, and simple payback.
Eleven working forms: a site survey, a roof and catchment worksheet, a monthly water balance, a storage sizing sheet, a parts and rules checklist, and rainfall, filter, water-test, irrigation, cost and repair records.
Twelve two-page Monthly Logs, one spread per month.
Eight reference tables, including the formulas at a glance, and a glossary.

Written for homeowners in the United States and the United Kingdom, with US gallons and inches alongside liters and millimeters. This is a working guide, not a substitute for local rules or a qualified professional. Every quantity, price and time is an example. Local regulations, the makers' data and a licensed installer take precedence, and any indoor or drinking use of rainwater needs treatment, testing and permission.
