Lawn Drainage Problems in Chichester & West Sussex

Written By Bradley Firth

Why your lawn gets waterlogged — and how to fix it properly

If your lawn regularly turns soggy, muddy, or unusable after rain, you’re not alone. Lawn drainage problems are extremely common across Chichester and the surrounding villages — particularly in gardens with poor soil structure or limited natural drainage.

In this guide, we’ll explain why lawns become waterlogged, the most common causes locally, and the best long-term solutions to fix drainage issues properly.

Signs Your Lawn Has a Drainage Problem

You may have a drainage issue if:

  • Water sits on the surface for hours or days after rain

  • The lawn feels spongy or muddy underfoot

  • Grass turns yellow or patchy

  • Moss becomes dominant

  • The lawn is unusable for large parts of the year

These issues don’t fix themselves — and re-turfing alone rarely solves the problem.

Why Lawn Drainage Problems Are Common in Chichester

Across Chichester and wider West Sussex, drainage problems are usually caused by one (or more) of the following:

1. Poor Soil Structure

Many local gardens have:

  • Heavy clay layers

  • Compacted subsoil from construction

  • Thin topsoil laid over poor ground

Water struggles to pass through, so it sits on the surface.

2. Compacted Ground

High foot traffic, machinery, or years of use can compress soil, leaving no air gaps for water to drain.

This is common in:

  • Family gardens

  • Dog runs

  • New-build properties

3. Incorrect Garden Levels

If your lawn slopes towards the house or sits lower than surrounding ground, water naturally collects there.

Even small level errors can cause major drainage problems.

4. Lack of Proper Drainage Infrastructure

Many gardens simply have:

  • No drainage system

  • Old, blocked drains

  • Inadequate soakaways

Without somewhere for water to go, it stays put.

Why Simply Re-Turfing Doesn’t Work

A common mistake is replacing turf without fixing the drainage below.

This often leads to:

  • New turf failing

  • Ongoing waterlogging

  • Wasted money

💡 The problem is almost always beneath the surface.

Effective Lawn Drainage Solutions

French Drains

A French drain is a gravel-filled trench containing a perforated pipe that redirects excess water away from the lawn.

Best for:

  • Consistently waterlogged areas

  • Sloping gardens

  • Larger lawns

Soakaways

A soakaway collects water and allows it to disperse slowly into surrounding ground.

Best for:

  • Standing water after rain

  • Low points in gardens

  • Areas with reasonable subsoil permeability

Lawn Re-Levelling & Ground Preparation

Sometimes drainage issues are caused by poor original installation.

Solutions may include:

  • Removing turf

  • Improving subsoil

  • Installing drainage

  • Re-laying turf correctly

This creates a permanent fix rather than a cosmetic one.

Aeration (Short-Term Improvement)

Mechanical aeration can help mildly compacted lawns by creating channels for water and air.

⚠️ This is usually a temporary improvement, not a permanent fix for serious drainage problems.

When Is the Best Time to Fix Lawn Drainage?

Drainage work can be carried out year-round, but:

  • Late spring to early autumn is ideal

  • Drier ground allows better installation

  • Lawns recover faster

If your garden is already unusable in winter, it’s often best to fix the issue before re-turfing.

How Long Does Drainage Work Take?

Typical timeframes:

  • Small drainage repairs: 1–2 days

  • Full lawn drainage & re-turfing: 3–5 days

  • Complex or large gardens: varies

Correct installation is far more important than speed.

Do You Need Professional Help?

Drainage is one of those jobs where experience matters. Poorly installed drains can:

  • Fail completely

  • Cause flooding elsewhere

  • Create long-term ground problems

A professional assessment ensures:

  • The right solution is chosen

  • Levels are correct

  • Water is directed safely away
