As climate patterns evolve, water management has become a critical concern for golf clubs, writes Greg Evans of Golf Course Solutions. Traditional irrigation and drainage cycles are being disrupted, with clubs increasingly facing extended drainage periods.
Where six months each of irrigation and drainage once sufficed, many clubs now contend with up to eight months dedicated to drainage (September to April) and only four months of irrigation, primarily between May and August.
To address these challenges, clubs are adopting sustainable strategies, including scheduling drainage projects when soil conditions are dry. While this can conflict with busy event calendars, it is crucial for ensuring the longevity and effectiveness of these systems. Dry soil prevents compromise, laying the groundwork for long-term success.
The summer renovation period, typically mid-July to mid-August, is an ideal time for such work. Notable examples include over 10,000 metres of drainage installed at Muswell Hill and Singing Hills Golf Clubs this summer.
Although newly installed systems offer substantial long-term benefits, their full impact takes time to materialise. It can take 12 to 24 months for these systems to stabilise and integrate fully with the new infrastructure. The first winter may show only moderate improvements, with optimal performance only emerging in subsequent seasons.
Advances in drainage strategies over the past decade have significantly improved system efficiency. Modern designs feature narrower pipe spacing (3 to 5 metres on fairways and as little as 2 metres on greens) compared to the previous 10-metre standard.
Equally critical is the integration of secondary drainage methods. High capital investments in pipe installations must be supported by complementary practices, such as regular aeration and sand dressing, to maintain topsoil functionality and prevent pipe contamination. Addressing challenges like worm activity is also vital for ensuring long-term system performance.
Accurate mapping of existing systems is essential during drainage upgrades, as demonstrated by the ongoing re-draining of Ealing Golf Club since 2012. This project was necessitated by irrigation installations that inadvertently damaged older drainage infrastructure, highlighting the importance of careful planning.
Proactive, sustainable water management is imperative for clubs to maintain playability and profitability in a changing climate. By investing in advanced drainage systems and complementary agronomic practices, golf clubs can adapt effectively and ensure long-term success.
