Can You Use Rainwater Collection in a Skoolie?

Designing a Rainwater Collection System for a Skoolie

When designing a rainwater collection system for a skoolie, consider the roof size, which is typically around 300-400 square feet for a standard school bus. To collect and store enough water for a family of four, aim for a minimum of 250 gallons of storage capacity. This can be achieved using a combination of tanks, such as a 100-gallon black water tank and a 150-gallon freshwater tank.

Installing the Rainwater Collection System

Install a gutter system along the skoolie’s roof, using a 2x4 or 2x6 aluminum gutter with a 1/4-inch mesh guard to prevent debris from entering the system. The gutter should be sloped at a 1/4-inch per foot pitch to ensure water flows freely into the downspout. Connect the downspout to a 1,000-gallon-per-hour first flush device, which will divert the initial contaminated water from the roof into a separate drain, allowing clean water to flow into the storage tank.

Maintenance and Considerations

Regularly inspect and clean the gutter and downspout system to ensure optimal performance and prevent clogging. Use a 1-micron filter in the storage tank to remove any remaining debris and contaminants. Consider adding a UV purifier or other water treatment system to ensure the collected water is safe for drinking and household use. Additionally, ensure the skoolie’s layout is designed to accommodate the rainwater collection system, including adequate space for the storage tanks and easy access for maintenance.
