Blocked drains can bring work on a busy construction site to an abrupt halt. Silt, rubble and building residue often enter exposed drainage, while heavy rain can leave excavations and access routes flooded. BDS Drainage provides planned and emergency support for construction sites throughout London, Essex, Kent and Surrey.
We work with building contractors, developers, site managers and commercial property teams. From small refurbishments to larger developments, we adapt our work to suit the site programme, access arrangements and current stage of construction.
Our services include:
Our engineers follow site access procedures and communicate clearly with the person responsible for the job. We’ll also coordinate our work around deliveries, machinery and other trades wherever possible.
Construction debris can quickly restrict a drainage system. Common causes include mud, silt, aggregate, grout, plaster and general waste entering open channels or unprotected pipework.
We can assist with:
We use professional jetting and clearance equipment to restore flow where possible. If we suspect solidified material or structural damage, we’ll investigate further before recommending the next step.
Drainage plans aren’t always accurate, particularly on refurbishment sites or properties that have been altered several times. A CCTV survey can help locate hidden faults and provide a clearer picture of the existing system.
Our survey work can identify:
Drain tracing can also help establish where pipes run before excavation begins. This reduces guesswork and helps project teams make informed decisions about repairs, alterations and new connections.
Heavy rainfall, damaged drainage or a sudden blockage can leave working areas flooded and access routes unsafe. Our emergency service is available 24 hours a day, with a target response time of 90 minutes for urgent callouts.
We respond to:
Our first priority is to assess the immediate problem and restore drainage where practical. We’ll then explain whether cleaning, investigation or repair work is needed.
Not every construction project has its permanent drainage fully operational from the start. Temporary arrangements may be required to control surface water, support welfare facilities or keep key work areas usable.
We can assess existing drainage, clear temporary pipe runs and advise on practical short-term measures. For permanent installations or engineered dewatering systems, we can work alongside your site team and relevant specialist contractors to help establish what drainage support is required.
Tell us what’s happening, which areas are affected and whether there are any access or induction requirements.
Our engineer inspects the drainage, considers the surrounding work and chooses the safest suitable method.
We use jetting, mechanical clearance or CCTV equipment depending on the nature of the problem.
We explain what caused the issue and outline any repairs, cleaning or ongoing maintenance that may be needed.
Our construction drainage contractors attend sites throughout Greater London and across Essex, Kent and Surrey. We regularly travel to developments in and around Croydon, Bromley, Dartford, Maidstone, Romford, Basildon, Chelmsford, Epsom and Guildford, as well as the surrounding towns and boroughs.

Yes. A pre-construction CCTV survey can identify defects, locate connections and provide useful information before excavation or redevelopment.
Yes. We can clean and inspect site drainage before handover to help identify leftover debris, restrictions or damage.
We can use CCTV and drain-tracing equipment to help establish the route and condition of accessible drainage runs.
Yes. We coordinate with the site manager and work around access arrangements, deliveries and other trades wherever practical.
Yes. Regular cleaning can be arranged for longer projects, particularly where mud, silt and debris repeatedly enter the drainage system.
