Why your pitch floods — and how to fix it
6 min read · Updated June 2026
A pitch that holds water costs you fixtures, revenue and goodwill. Before you assume you need an expensive new drainage scheme, it is worth understanding why the water is not getting away — because the cause dictates the cure, and the cheapest fixes solve a surprising number of cases.
This guide walks through the usual culprits, from compaction to a failing pipe system, and the work that addresses each.
Most flooding starts with compaction
On the majority of community pitches, standing water is not a drainage-pipe failure — it is compaction. A hard pan a few centimetres down stops water reaching whatever drainage exists below. The water has nowhere to go, so it sits on the surface.
The good news is this is the cheapest problem to fix. Aeration — particularly deep-tine work or vertidraining — fractures the pan and gets water moving again. Many "we need new drainage" pitches are transformed by a proper aeration programme alone.
Secondary drainage: sand banding and slitting
If aeration is not enough, the next step up is secondary drainage — sand bands or gravel slits cut into the surface at regular spacings, linking the playing surface to the drains beneath. This creates fast vertical routes for water to escape and is far less disruptive and costly than a full primary scheme.
Primary drainage: the big fix
A primary drainage system is a network of perforated pipes in gravel-filled trenches, laid in a herringbone or grid and running to an outfall. It is the most thorough — and most expensive — solution, and is usually combined with a sand-based rootzone and secondary drainage to work properly.
Because it is a major construction job, it makes sense to start with a drainage survey so you spend on the right solution rather than over-engineering.
Spend in the right order: a drainage survey and an aeration programme first, secondary drainage next, and a full primary scheme only when the survey shows it is genuinely needed.
What does it cost?
Costs span an enormous range. An aeration programme is the most affordable intervention; secondary drainage such as sand banding on a full pitch is commonly in the low-to-mid thousands; a full primary drainage scheme with rootzone can run well into five or even six figures.
A survey is the cheapest money you can spend here — it tells you which of those you actually need. Post a brief and verified drainage contractors will assess your pitch and quote.
Common questions
Do I need new drainage or just aeration?
Often just aeration. Compaction is the most common cause of surface water, and relieving it with deep-tine work or vertidraining fixes many pitches. A drainage survey will confirm whether you need more.
How disruptive is sand banding?
Sand banding is relatively quick and the pitch is usually playable soon after. It is far less disruptive than installing a primary pipe system, which takes the pitch out of use for an extended period.
What is a drainage survey?
A contractor assesses your soil profile, existing drainage and water table, often with trial holes, and recommends the most cost-effective fix rather than defaulting to the most expensive one.
