Why ACO drains become blocked in Kingston properties

Table of Contents

ACO drains are a popular choice for Kingston driveways, patios and garden areas because they collect surface water quickly and prevent flooding. However, many homeowners experience recurring blockages — especially during autumn and winter when rainfall increases and debris builds up fast.

This guide explains why ACO channels block so easily, how to spot early warning signs, and the best long-term ways to keep your drainage system running smoothly.

1. What ACO drains are designed to do

ACO channels sit at ground level and capture rainwater before it pools. The water then travels through a narrow channel into your main drainage system.

In Kingston, these drains are commonly installed:

  • Along driveway entrances
  • Between patio slabs
  • Beside garages
  • Across garden paths
  • At property thresholds to prevent water entry

Their effectiveness depends heavily on correct installation and regular maintenance.

2. Why ACO drains block so often in Kingston

2.1 Leaves, moss and garden debris

Kingston’s tree-lined residential areas — Surbiton, Coombe Hill, Norbiton, and Ham — naturally produce large amounts of leaf litter. This debris enters the grating and gathers inside the channel, slowing water flow.

2.2 Silt and sediment buildup

Driveway runoff often contains soil, sand, car grit and fine particles. These settle at the base of the channel, gradually reducing capacity.

2.3 Sloped driveways that push debris directly into the channel

Homes with a downward slope toward the road or garage send large volumes of surface material into the drain every time it rains.

2.4 Blocked outlet pipes

Even if the ACO itself is clear, the connecting pipe may be blocked deeper underground — often by scale, silt or structural defects.

2.5 Incorrect installation depth or alignment

Common installation mistakes include:

  • No fall (pipe should slope to allow flow)
  • Outlet pipe fitted too high
  • Insufficient number of channels for property size
  • Missing silt traps

These issues are frequently discovered during CCTV inspections.

2.6 High clay content in Kingston soil

Much of Kingston has clay-heavy ground, which washes into channels and forms thick sludge when wet.

3. Warning signs your ACO drain is blocked

Look out for these common symptoms:

  • Water overflowing from the grating
  • Slow drainage after rainfall
  • Standing water around driveway edges
  • Mud streaking around the channel
  • Bad smells from the outlet
  • Visible silt inside the channel after lifting the grating

If the system backs up despite cleaning the surface grate, the issue may be deeper in the underground pipework.

4. How we clear blocked ACO drains in Kingston

A typical professional clearance includes:

4.1 Removing all ACO grates

We lift and manually remove debris, leaves and moss from the full channel length.

4.2 High-pressure water jetting

Jetting is used to flush silt and mud from the channel and the connecting outlet pipe.

4.3 CCTV drain inspection

A post-clean camera survey can identify:

  • Collapsed pipe sections
  • Root intrusion
  • Poor installation levels
  • Broken connectors
  • Hard blockages

4.4 Repairs or upgrades where required

If the outlet pipe is damaged, we may recommend:

  • CIPP patch lining
  • Full relining
  • Outlet re-installation
  • Adding silt baskets

5. Preventing blockages in the future

✔ Install a silt trap or debris basket

Stops leaves and grit entering the outlet pipe.

✔ Clean the ACO grates seasonally

Especially during autumn in Kingston’s leafy neighbourhoods.

✔ Use a pressure washer periodically

Keeps channels flushed and clear.

✔ Ensure correct installation

A CCTV survey confirms the system is aligned and draining correctly.

✔ Jetting once a year

A routine jet ensures the connecting pipes remain clear of silt.

ACO Drainage FAQs

Why do ACO drains block so easily?

Leaves, grit, soil and debris wash into the channels, especially in leafy Kingston areas like Coombe Hill and Surbiton. Without regular cleaning, these materials build up and restrict flow.

How often should I clean my ACO drains?

Seasonal cleaning — particularly in autumn — is recommended. Homes near trees may require more frequent maintenance.

Can blocked ACO drains cause flooding?

Yes. If the channel or outlet pipe blocks, water can overflow and cause pooling around driveways and foundations.

Do ACO drains need a CCTV survey?

If blockages keep returning, a CCTV survey can uncover deeper issues such as structural damage or a misaligned outlet pipe.

Can you repair damaged ACO drainage pipes?

Yes. Repairs may include CIPP patch lining, pipe realignment or full outlet replacement depending on the issue.
