Adding an irrigation system can make it easier to keep your lawn, garden, landscaping, or other outdoor areas watered throughout the drier months in Olympia, WA. But if your home relies on a private well, there’s an important question to answer before installing sprinklers: Can your well meet the additional demand?
A well that comfortably supplies your household may not necessarily have enough capacity to support regular irrigation at the same time. Understanding your existing system can help you plan an irrigation upgrade without causing frustrating water pressure or supply problems.
What Does Well Capacity Mean?
Well capacity generally refers to how much water your well can reliably provide. One important measurement is the well’s flow or yield, often expressed in gallons per minute.
However, well performance involves more than a single number. The depth of the well, static water level, pumping water level, pump capacity, storage, plumbing, and groundwater conditions can all affect how much water is available when you need it.
Your household’s existing demand matters, too. Showers, toilets, washing machines, dishwashers, and other fixtures may already be drawing water when your irrigation system turns on.
Irrigation Can Create Significant Demand
An irrigation system may require a substantial amount of water over a relatively short period. Multiple sprinkler heads operating simultaneously can place a much greater demand on a well than typical household activities do.
If demand exceeds what your well and pumping system can comfortably supply, you might experience reduced pressure or inadequate sprinkler performance. In some cases, excessive pumping can lower the water level faster than the well can recover.
That’s why determining available capacity should come before deciding how large your irrigation system will be.
Have Your Existing Well Evaluated
Before adding irrigation, consider having a qualified well professional evaluate your current system.
Testing can provide information about the well’s yield and how its water level responds during pumping. A professional can also examine the pump and pressure system to determine whether they are appropriately sized for the additional demand.
Keep in mind that groundwater conditions can change over time. Information from when your well was originally drilled may be useful, but current testing can provide a clearer picture of how the system performs today.
You May Have Options Besides Drilling Deeper
Discovering that your existing setup can’t support your proposed irrigation system doesn’t necessarily mean you need an entirely new well.
Depending on your property and system, solutions might include dividing irrigation into smaller zones, changing the watering schedule, adding appropriate water storage, modifying pumping equipment, or making other system improvements. In other situations, changes to the well itself may be worth considering.
Our well professionals can recommend options based on the actual performance of your system rather than guesswork.
Plan Before You Start Watering
Olympia homeowners often rely on irrigation most when seasonal rainfall decreases and landscapes need additional water. Planning ahead can help ensure your well is prepared for the extra demand.
Before investing in sprinklers or expanding your landscaping, determine what your well can realistically supply. A professional well-capacity evaluation can help you design an irrigation system that works with your available water supply while still meeting your household’s everyday needs.
