The problem

When the property owner in SW9 discovered their basement had flooded, they faced multiple urgent concerns that extended beyond simple water removal. The flooding had created standing water throughout the space, posing immediate health and safety risks. A blocked manhole was preventing proper drainage, compounding the problem and threatening to cause further water accumulation.

The client’s primary concerns centered on three critical issues:

Lingering water damage: The extent of the flooding meant that simply removing visible water wouldn’t be sufficient. Without proper extraction and cleaning, moisture could seep into walls, floors, and structural elements, potentially causing long-term damage.

Health hazards: Standing water in basements can quickly become a breeding ground for bacteria, mold, and other contaminants. The client needed assurance that the space would be thoroughly sanitised to eliminate any health risks.

Usability and safety: The basement needed to be restored to a fully functional, safe space. This required not only clearing the water but also ensuring all drainage systems were operational and the area was properly cleaned.

The urgency of the situation demanded a drainage company capable of responding quickly with the right equipment and expertise to handle all aspects of the job—from unblocking to deep cleaning.

The solution

BDS Drainage’s team arrived promptly to assess the situation and implement a comprehensive restoration plan. Their approach combined specialised equipment with systematic cleaning protocols to address every aspect of the flooding emergency.

Phase 1: Water extraction
The engineers deployed a professional vac machine to extract all excess water from the basement. This industrial-grade equipment ensured thorough removal of standing water, including water that had seeped into corners and low-lying areas.

Phase 2: Drain clearance
To address the root cause of the flooding, the team used a high-pressure jet washer (HPJW) to clear the blocked manhole and drainage system. This powerful equipment effectively removed blockages and ensured water could flow freely through the drainage network, preventing future flooding incidents.

Phase 3: Deep cleaning and sanitisation
Following water extraction and drain clearance, the team conducted a thorough deep clean of the entire basement floor and affected areas. Specialised cleaning chemicals were applied to sanitise all surfaces, eliminating bacteria, odors, and potential health hazards. This critical step ensured the basement was not only dry but also hygienically safe for use.

Phase 4: System verification
Before completing the job, BDS Drainage verified that all drains were unblocked and functioning properly, with water flowing freely through the system. The team ensured the property was left in full working order, giving the client peace of mind that the problem had been completely resolved.
