How to Plan Successful Drip Irrigation Systems

1. Carefully evaluate the property and landscape

During your property walk-though, take note of factors that can impact irrigation performance—like elevation changes, soil type, and sun exposure. Create a detailed site sketch that includes planting beds, trees, and other irrigated areas as well as hardscape features that may affect tubing placement.

DRIP TIP: For sloped terrain, plan to use pressure-compensating emitters or dripline to help ensure consistent water distribution across varying elevations.

2. Organize irrigation zones according to water usage

To maximize the precision and efficiency of your drip setup, group plants with similar water needs into dedicated irrigation zones. For example, flowering annuals often require more frequent irrigation than mature shrubs, native plants, and drought-tolerant species. Proper zoning allows each landscaped area to receive the appropriate amount of water.

DRIP TIP: To set up an irrigation zone quickly, opt for an all-in-one control zone kit that comes preassembled with a valve and pressure-regulating filter.

3. Plan tubing routes for optimum system performance

For an efficient tubing layout, avoid unnecessary complexity and sharp bends that can disrupt water flow. Use stakes to keep tubing in place, the appropriate fittings to ensure secure connections, and single- or multi-outlet emitters to deliver water where needed.

Exceeding recommended tubing run lengths or overloading a line with too many emitters can degrade system performance so it's a good idea to check product specs. The NDS specifications library is a good resource, with a search bar to help you find what you need.

What is the 200/200 rule?
Some contractors use the 200/200 rule as a rough planning guideline: limiting tubing run lengths to a maximum of 200 ft. and the total flow rate of drip emitters for each line to 200 GPH.

DRIP TIP: Need a longer run? NDS Dura Flo™ CV Check Valve 17mm Dripline enables runs of up to 314 ft. while also reducing header materials and installation labor.

4. Plan for the possibility of future expansion

Landscapes often evolve over time with new planting beds, garden areas, or outdoor living spaces. You can make it easier to accommodate future irrigation projects by integrating flexibility into your original design—such as adding extra outlets that can be capped until needed.

DRIP TIP: For even more flexibility now and in the future, choose Smart Loc™ fittings that work with a variety of supply tubing and dripline sizes. Bonus: They're easy to remove and reuse!
