California residents are encouraged to use rainwater tanks to decrease their reliance on imported water.
This Rainwater Capture Act of 2012 was passed to help California reduce potable water demand by at least 20% by 2020.
Every Los Angeles resident is now permitted to collect rainwater that falls on their properties.
How much does a larger tank or cistern cost?
Large tanks range in cost depending on the size and system being installed. Small tanks start at around $300 and upwards.
Installation cost depend on tank size, how the water will be used, how the water is exported and if it is above or below ground.
We expect to see cisterns and larger tanks become more affordable in the future. Consider solar panels, for instance. In 1977, solar energy cost $76.77 a watt. As demand increased, price decreased significantly. Today, it's less than 62 cents per watt.
What if I can't afford one right now?
You can still make an impact during the drought by installing rain barrels and using native plants in your yard at home.
