Allan Standen Residence
System Overview
Allan Standen's residence is a testament to the power of rainwater harvesting. With a total roof area of 4,000 square feet, the system collects and stores 20,000 gallons of rainwater between two 10,000 gallon fiberglass tanks.
The system supports the daily demands of 2 to 3 people and 4 pets (50 gallons per person, totaling 30,000 gallons per year). The system typically requires 1 to 2 loads (2,000 gallons each) per year to sustain trees on the property.
The system utilizes a treatment train that consists of two-stage sediment filtration, a polishing filter, and UV-sterilizer for disinfection.

System Overview
The Froelich family's rainwater harvesting system demonstrates the capability to support the needs of a large household. With a total roof area of 4,000 square feet (3,600 sq ft main house + 400 sq ft guest house), the system captures and stores rainwater in two 15,000-gallon concrete tanks.
The system with the tank integrated beneath the house foundation with synthetic piping system concealed behind walls to minimize freeze issues in winter and keep water cool in summer. The system maintains a 6-month supply at all times and includes a treatment train with two-stage sediment filters, UV light sterilizer and leak protection through electronic monitoring with automatic shutoff valves.
The system supports a family of 8 with monthly demands of 5,000–6,000 gallons, totaling 60,000–72,000 gallons annually. The system even supported filling the above ground pool for three consecutive summers. However, during the 2011 drought, 56,000 gallons of supply had to be trucked in (26 truckloads) to cover the family's needs.
