About Greenwich

Greenwich lies in south-east London on the south bank of the Thames. It takes in Woolwich, Eltham and Blackheath, as well as Greenwich town, Charlton and Plumstead. The land rises from the riverside up to Shooters Hill.

Because of this, drains behave differently across the borough, with steep slopes in some places and flat ground by the river in others. The Royal Borough of Greenwich manages highway drainage, so report blocked road gullies or road flooding to its environment and transport service. Drains inside your property boundary are private.

Property types: Victorian terraced housing across Woolwich, Charlton, and Plumstead; Edwardian and interwar semi-detached properties in Eltham; Georgian architecture around Greenwich town; 1930s and post-war housing on the Eltham and Avery Hill estates; modern development in the Greenwich Peninsula.

Drainage in Greenwich

Victorian clay drains dominate Greenwich town, Woolwich, Charlton and Plumstead, while Eltham has Edwardian and interwar clay. The Greenwich Peninsula and Woolwich Arsenal have modern drainage. A CCTV drain survey is wise before any major property work.

London Clay covers the higher ground around Shooters Hill, Blackheath and Eltham, while river deposits lie under the low ground by the river. The height range is large, so drainage conditions differ a great deal. This is the biggest factor in the problems we see in any one postcode.

Homes near the Thames can see sewer backup when spring high tides meet heavy rain. This applies to the Greenwich Peninsula, Charlton riverside, Woolwich and Thamesmead. The Environment Agency's long-term flood risk service gives property-level maps. Use it to check your own address.

On Shooters Hill, Blackheath and the Eltham high ground, the opposite problem applies. Steep drains carry fast flows, which can wear clay pipe joints, while roots also tend to collect where the slope flattens.

Several problems come up across Greenwich. Tidal backup affects lower-ground units, and a check valve can fix it. Fast flows wear joints on the slopes, so a CCTV survey and no-dig pipe relining help.

Trees in Greenwich Park, Charlton Park and Oxleas Wood send roots towards nearby drains, and high-pressure drain jetting clears them. Shared drains in Victorian terraces in Charlton and Plumstead can back up several houses. Converted units at Woolwich Arsenal are worth surveying before you buy.

Our emergency drain team covers SE3, SE7, SE9, SE10, SE18 and SE28, while we also work with our neighbouring Lewisham and Bromley pages for homes along the borough boundary.

Greenwich drainage FAQs

I live near Greenwich Park — does the park cause drain problems?

Homes next to Greenwich Park can see roots from the park's mature trees. Because these trees have had a long time to grow, their root systems are deep. If your property backs onto the park, a CCTV survey of your drain every few years is wise. Roots may be present before they cause a full blockage.

Does the tidal Thames affect drains in Greenwich Peninsula and Charlton riverside properties?

It can. Lower-ground and basement properties near the river can see sewer backup when spring high tides meet heavy rain. Since this is a backflow problem, the usual fix is a non-return (check) valve on the affected drain. It is also worth testing any existing valve each year. The Environment Agency's long-term flood risk service has property-level maps for the area.

Why do drains on Shooters Hill, Blackheath and Eltham slopes need different treatment?

Steep drains carry fast flows, which can wear clay pipe joints and move debris downhill. Roots and silt then collect where the slope flattens, because the flow slows there. A common sign is a repeat blockage some way downhill of an otherwise clear run. The right approach is a CCTV survey to find the weak point. No-dig relining of that section then works better than another round of rodding.
