Replacing a golf course irrigation system: what to settle before you commit

When a golf course irrigation system reaches the end of its life

The USGA puts an irrigation system's traditional useful life at about 25 years. The City of Coronado, California, describes a system installed in 1957, and Southborough, Massachusetts, described its town course's system as more than 50 years old in a 2023 funding application.

Age is a prompt to look, not a verdict. A Georgia state audit in October 2025 found the systems at two state-park courses past the typical 30-year maximum life span it cited (at one, only the original nine holes) and said they may need replacing soon, yet it described both courses' current condition as good. What matters is what the system is doing now: how often it breaks, how much hand-watering it needs, and whether a single failure can stop the whole course. Coronado's project page notes that its system has no mainline isolation valves, so any mainline break would force a shutdown of the whole system.

What a new irrigation system costs, and why the price keeps moving

In January 2024 an article in the USGA's Green Section Record said that, had Bend Golf Club in Oregon and Worcester Country Club in Massachusetts needed new irrigation, the system alone would have started at $2.5 to $3 million, and at $4 million or more on the West Coast, while noting that costs are hard to generalize. The USGA's Water Conservation Playbook says a new system can cost $3 million and, in some cases, more than $5 million. The Golf Course Superintendents Association of America's 2025 survey of 18-hole courses measures something else: the new irrigation projects superintendents reported completing in the previous three years averaged about $1.53 million, the highest of any project type, and the survey does not say how large those projects were.

Estimates for single courses vary widely. For Chelan, Washington, a National Golf Foundation evaluation in May 2026 gave a preliminary estimate of $3.75 to $4.5 million for a new system with a new pump station and modern controls, and Coronado's project page, last updated in December 2024, puts its irrigation and turf-reduction project at up to $9 million.

Lead times are long. Golf Inc. reported in September 2025 that the executive director of the Golf Course Builders Association of America was seeing most projects bid out at least a year in advance. A budget should say when its prices were taken.

Replace, phase or repair, and where a renovation fits

Most owners face a choice of scope rather than a simple yes or no. A full replacement renews the whole system, often including the pump station, in one project. A phased replacement spreads the work over several seasons. Targeted work starts with the parts that fail most: in April 2026 the City of Chillicothe, Missouri, approved $114,000 for irrigation control units serving all 18 greens at Green Hills, to be installed by its own staff.

Some owners start with an audit. In 2020 the City of Port Orange, Florida, planned to replace all 19 control boxes at Cypress Head after an irrigation audit, then still under way, found they needed replacing; the City expected the same audit to show whether the underground piping and heads needed replacing too. Whatever the starting point, compare the options in writing, against the same baseline, because the scope changes the number. When the public utility district of Grant County, Washington, voted in February 2026 to keep the Crescent Bar course in its recreation plan, it put the cost at $3.1 million, or less if the irrigation system did not need complete replacement; a week earlier its staff had called $3.1 million the minimum capital cost of replacing the system.

If a renovation is coming, settle it first. A USGA Green Section Record article in February 2025 called installing irrigation before developing a long-range master plan a surprisingly common mistake, and a contractor told Golf Course Industry in March 2026 that if new irrigation goes in before a renovation, moving the new heads essentially doubles the cost of installing them. If greens, bunkers or drainage are likely to change during the life of the new system, the irrigation should follow that plan rather than lead it. Our guide to renovating a golf course sets out how to compare a wider programme.

What the old system costs to keep, and what the course is worth

Every option should be compared with keeping the course as it is, and that baseline is not free. Repairs, staff hours spent hand-watering and the risk of a mid-season failure are all costs.

They also show in what the course is worth. An appraiser writing in the 2025 Golf Investment Report of LIPG, a golf brokerage, notes that a course needing an immediate infusion of capital will often trade at a higher capitalization rate, which for the same income means a lower price. In our view, a buyer who sees an ageing system will price its replacement, whether or not the owner has.

What a lender will ask about an irrigation project

If a loan pays for the work, expect the lender to test the budget. For loans to rehabilitate or modernize an older property, the handbook the Office of the Comptroller of the Currency (OCC) gives bank examiners says banks typically obtain an independent evaluation of the budget from a qualified engineer or architect, and it says construction budgets usually carry a contingency of 5 to 10%.

The same handbook states that "Cost increases do not necessarily result in an increase in value." What a new system can change is the risk a buyer or lender sees.

Water decides more than the pipes

A new system is the moment to settle the water behind it, and the water can change the project. In March 2024 Southborough's Town Meeting approved $553,750 of Community Preservation funding, including a $78,750 contingency, to replace the irrigation at its nine-hole town course. In January 2026 its public works superintendent told the town's Community Preservation Committee that bids had come in well beyond the approved funds and that the problem was water pressure and the need for a pump station. In October 2026 a Special Town Meeting approved up to $433,546 more, raising the Community Preservation total to $987,296, with a further $100,000 from the golf course's revolving fund, the local news site MySouthborough reported.

Pumps and wells can be projects of their own: in June 2026 the city-owned golf club in Fernandina Beach, Florida, listed a $150,000 well rehabilitation for 2027 separately from its proposed $2.7 million irrigation and drainage project.

A new system is also a chance to use less water, and public money sometimes helps pay for it. The Spanish trade site golfindustria.es reported in May 2026 that Golf Club Perelada's irrigation renewal, of about €1.5 million over 18 weeks, cut estimated annual water use from just over 330,000 to about 240,000 cubic metres and reduced the irrigated area from 40 hectares to under 28. Granada Club de Golf completed a smart-irrigation modernisation of just over €1.2 million, with 65% met by EU recovery funds through the regional government of Andalusia.

Paying for it: reserves, members or a loan

Most courses pay from their own cash, and many combine sources. In the GCSAA's 2025 survey, cash reserves were the most common source of funding for capital projects, named by 68% of respondents, followed by monthly capital dues at 30% and commercial loans at 24%. Assessments were named by 21%, and only 34% agreed that funding for capital projects at their facility was sufficient.

At a private club the members usually decide. In a 2025 survey of private-club board members by the consultancy GGA Partners with the National Club Association, 71% said a formal member vote was required to advance capital projects, and only 40% were willing to fund projects with debt. Public owners move with the budget cycle: the replacement at Creve Coeur, Missouri, was among the future projects in the City's April 2022 programme, moved into its five-year programme in April 2024, and was carried out in fiscal year 2026 for $890,000, offset by a $406,050 grant from the Municipal Park Grant Commission.

Before you replace, refinance, sell or hand over

Settle three questions first. What does the current system cost to keep, and how likely is a failure this season? What does each option change in revenue, costs and what the course is worth, including any closure? And how will the work be paid for, and what will that do to the balance sheet and the members?

An irrigation consultant or designer can tell you what the system needs and what a replacement involves. Slope Intelligence looks at a different question: what the work would do to the course's capital position, its value and how it is funded.

The Capital Readiness Assessment · Proposed programme examines the irrigation work you are considering beside the course as it stands, with its costs, funding and dependencies. It is commissioned alongside the Capital Readiness Assessment · Current situation, which gives the course an AssetScore across 10 categories and 43 data points, sets out the material risks with their evidence, and includes an indicative value range where agreed and supported by the evidence. The range is separate from AssetScore and is not a formal valuation or appraisal, and a conditional score or value improvement does not establish permission, funding or an investment return. The assessment is licensed for internal use only; it may not be shared with a lender, buyer or other external party.
