How Much Rainwater Can You Collect in Ramona?

As of September 2011, the average annual rainfall in Ramona is 17 inches per year. The amount of water that will come off your roof may be a surprise.

Ramona is considered a semi-desert climate. We don't really get all four seasons, weather-wise. Our fall, winter, and spring weather are fairly the same. Our summer goes from great warm weather to feeling like an unbearably hot desert.

The hottest months are August and September, where temperatures are often in the 90s to 100s. Just down the hill, in San Diego the temperatures are usually 10 degrees cooler in the summer and 10 degrees warmer in the cooler months.

For the sake of being conservative, let's say the rainfall is less; 10 inches per year in Ramona. If you had one thousand square feet of roof collected a conservative rainwater yield would be 6,240 gallons.

If a home had a 1,000 gallon cistern or a series of smaller barrels connected together and they entered summer with full tanks they would have 11 gallons per day for three months to water their gardens.

Another thing people don't think enough about is what happens in an emergency when the , like it did a few years ago in the fires. No electricity means the to our homes in Santee aren't working, and we lose water pressure. Imagine how it would be in a if your home was , as the government suggests it could be.

Imagine the peace of mind that would come from having hundreds of gallons of rainwater stored and a simple filter to make the water drinkable?
