How can I collect rainwater for irrigation?

No matter the size or shape, a rainwater collection tank should ideally have all these common elements:

• An inlet or downspout to direct the rainwater into the tank, generally on top but covered with a screen.
• An outlet that allows you to dispense and use the collected rainwater, usually near the bottom. For large tanks, a hose bib that you can connect a hose to is ideal.
• Made of a non-transparent material that does not allow sunlight through, unless you can completely cover it with a tarp (or paint) to block the sunlight. Sunlight + Water = Algae.
• Have fine-mesh screens securely in place over all openings to prevent the entry of insects, pests, or debris.
