So, you’ve stumbled upon a gorgeous parcel of land in the countryside in California!

The views are fantastic.

The cost is reasonable.

You are already imagining what you would like to create there.

However, don’t get too excited yet. There is one important question to answer: Can this land support a septic system?

A percolation test is just the way to discover that. Also known as a “perc test,” the test measures the water-absorbing capabilities of the soil on a land parcel. It is technical but simple. Holes are excavated in the ground, water is placed in the holes, and a time is taken to see how fast the water drains out.

The answer will indicate if the ground can hold a septic system. This is an underground system used to dispose of wastewater on properties not served by a public sewer.

If the land fails a perc test, it can have a big impact on what you can do with it. That’s why you need a perc test before you Buy Vacant Land California.

Why is this so important?

In California, most of the land in rural areas is not served by a public sewer system. If you’re thinking of building a home, a cabin, or any other structure that has a bathroom or kitchen, you will need a septic system to deal with wastewater.

Now, here’s the thing: a septic system will not function unless the soil is draining properly. The land may not be able to support a septic system at all if the soil is:

• Too dense
• Too rocky
• Absorbs water too slowly.

No septic system means no plumbing. Without plumbing, there’s no way to construct a habitable building. This may turn your dream land deal into a significant headache.

What is a perc test?

It’s a simple process.

• A licensed professional visits the land
• Makes a number of small holes in various locations on the property
• Water is poured into each hole, and the tester times how long it takes the water to fall 1 inch
• This is known as the “perc rate”

The higher the rate, the better the soil drains. A slower rate may mean that drainage is not good.

In California, perc tests must be approved by the local county environmental health department. Every county has a different set of standards for what allows a septic system to pass inspection.

Factors that may impact the results

A number of variables can affect the results of a perc test:

Soil type

Sandy soils have quick drainage. Clay soil is slow to drain and can be troublesome.

Slope of the land

Steep or uneven land can make it harder to install a septic system.

Water table level

If the water table is high, it can affect drainage and septic approval.

Season

Soil properties vary throughout the year. The test may yield different results if performed during a dry spell compared to a rainy period.

That’s why it’s always wise to have a professional perform a perc test for you. Somebody who has knowledge of the area and the requirements of the county.

What if the land fails the perc test?

A bad perc test does not necessarily indicate that the land is worthless. But it can certainly mean that you have a lot fewer choices. Sometimes an alternative septic system may be installed, for example:

• A mound system
• An aerobic treatment unit.

These systems are used on land that does not drain well. But they are more expensive than a typical septic system.

Other times, the land may not even be suitable for any permanent plumbing structure. If you’re planning to build a home, then that’s an issue. You may end up owning a piece of land that is completely inappropriate for you.

That is why it is essential to have a “perc test” completed prior to closing. A reliable real estate firm like Discount Lots will guide you on how to do it. It provides you with the information that you need to make the right decision.

Do you always need a perc test?

Yes, if:

• You are purchasing rural land in California
• You intend to put up any kind of plumbing.

In some cases, the seller might assure you that the land is “ready to build” or that the land was recently tested. It is advisable to have an independent test performed in your name.

A soil test may change over time. Previous test results may not accurately reflect the current condition of the land. Consider a perc test as a minor expense to prevent a major blunder.

The bottom line

A percolation test is one of the simplest and most important tests to perform before purchasing rural property. It provides you with clarity, the security of your investment, and the confidence to proceed with your plans. You will know that the land is capable of supporting what you wish to construct.

When in doubt, always test before you buy.
