Pump chamber repairs, servicing and replacements for wastewater and rainwater systems.
What is a pump station/chamber?
Pump stations are used where waste/water needs transferring from a basement or cellar (where no drain exists) up to a higher-level drain or pipe.
The chamber stores the liquid and a pump transfers it to the higher-level drain/pipe, controlled by float switches based on water level.
Where they’re used
- Basements and cellars
- Car parks
- New extensions and patios
- Schools, offices, restaurants and hospitals
- Industrial estates and hotels
How many pumps will I need?
Often one pump is suitable for smaller areas, but two pumps are used where higher rainwater/wastewater volumes require removal. A second (backup) pump covers peak flow or failure of the primary pump.

A documented drainage repair job including excavation and replacement work, supported by photo evidence and site reports.
- Site report: Excavate and replace damaged/collapsed ACO channel drainage at the entrance to the site
- Also included: Drain cleaning/de-scaling report
- Also included: Kitchen soil vent pipe cleaning report
Excavation and replacement of a failed ACO channel drain at a site entrance, shown with the five gallery photos you added and the extracted report images from the original job file.
- Scope: excavate the failed channel run and replace the damaged ACO rainwater drainage section
- Location: entrance drainage where surface water collection needed restoring
- Evidence: 13 combined site and report images covering the full job record
Why this repair matters
Damaged or collapsed channel drainage at entrances can cause standing water, unsafe surfaces, and ongoing deterioration around the paved area. Replacing the failed section restores proper rainwater collection and discharge.
What the job shows
- The replacement ACO channel positioned in the excavated run
- Barriered installation stages before the final surface finish
- The completed drain line reinstated and back in service
- Additional report images documenting the wider repair record
A before-and-after trenchless drain repair using insitu resin lining, showing how defective pipework can be rehabilitated internally without full excavation.
- Media: before and after videos of the repaired drain
- Method: insitu resin lining installed inside the existing pipe
- Outcome: restored flow path and structural condition with minimal disruption
Why use resin lining?
Insitu resin lining is a non-invasive repair method used where the pipe can be structurally renewed from within. It is especially useful for cracked, defective, or leaking drains where surface disruption needs to be kept to a minimum.
Typical benefits
- Minimal digging compared with traditional excavation repairs
- Reduced downtime for the surrounding area
- Suitable for targeted rehabilitation of existing pipework
What a CCTV drainage survey helps identify
- Causes of blocked drains
- Structural condition of below-ground drainage
- Accurate mapping of drainage runs and manhole chambers
- Repair methods and remedial repair costs (where required)
- Supporting evidence for insurance claims
What’s involved
- Initial discussion about symptoms (blockages, smells, rodents, damp, pre‑purchase checks)
- Written quotation and booking at a convenient time
- CCTV camera inserted via manhole chambers or access points
- Written report with images/photos and recommended repairs
What the survey can find
- Root intrusion
- Cracked, fractured, broken, or collapsed pipework
- Leaks/ingress and other service condition defects
- Blockage sources (fat, grease, scale, debris) and smell causes
Coverage: all London postcodes, Essex, Hertfordshire, Buckinghamshire & Bedfordshire.
We understand that when leaks arise this can be disruptive and cause extensive damage to property. Our highly experienced and qualified operatives use the latest technology to locate and resolve leaks, and where possible avoid disruption to your property.
Our leak detection methods
- Thermal imaging surveys — infrared inspection equipment to detect leaks where temperature changes occur.
- Tracer dye testing — coloured dye used within waste/soil and rainwater pipes to establish where leaks exist.
- Pressure testing — controlled air/water testing to confirm integrity loss; pressure drop indicates a leak.
- CCTV drainage surveys — camera equipment used in pipework/drains to locate cracked or damaged pipework.
- Tracer gas surveys — safe, non-toxic gas used to locate leaks in hidden/concealed pipework.
- Acoustic testing — non-invasive method to identify hidden leaks by analysing sound/vibration from escaping water.

Blocked Drains - Cleared using Electro Mechanical Equipment
Mechanical drain/pipe cleaning uses electric drain snakes with rotating flexible steel cables. It’s effective at removing fat, grease, scale, roots and deposits — especially stubborn blockages like tree roots, hair, scale and grease.
Mechanical cleaning methods and application
- Electro-mechanical equipment — handheld tools for toilets, sinks, baths, showers and urinal waste pipes; larger motor-driven machines for soil pipes and below-ground drainage.
- How it works — a flexible, rotating steel cable is inserted into the pipe/drain to break up and remove obstructions and blockages.
- What can be achieved — removal of root intrusion, hardened scale, fat/grease, stubborn rust and debris that high pressure water jetting cannot remove.
- Safety — operatives are fully trained and qualified to use electro-mechanical equipment.
Sometimes high pressure water jetting isn’t effective (or isn’t appropriate due to certain pipe materials or flood risk). Electro-mechanical methods provide an alternative option.
What is Picote drain cleaning equipment?
Picote refers to specialist heavy-duty mechanical machines designed to de-scale and clean soil pipes and drains where stubborn obstructions exist that cannot be removed by high pressure water jetting — or where water methods may not be suitable.
Using a high-speed rotating cable driven by flexible shafts, Picote is ideal when precision, power and adaptability are required for stubborn or deteriorated drainage and pipework, in both domestic and commercial properties.
When Picote equipment is used
- Removal of hard scale, rust or concrete content
- Cutting and removing root intrusion from drains
- Reinstating lateral connections after cured-in-place lining repairs
- Cleaning pitch fibre pipework prior to rehabilitation
- De-scaling cast iron soil pipes and below-ground drainage
- De-scaling vitrified clay and UPVC drainage/pipework
- Removing collapsed cured-in-place liners or failed patch liners
How Picote works
Picote equipment is powered by electric motors that spin a flexible shaft at high speed. Interchangeable cleaning heads are fitted depending on the pipe material and the obstruction/work required, with variable speeds for controlled but powerful cutting action.
