Full Drainage Installation for Old School Conversion in Bromley
BN Drainage designed and installed a complete drainage system for a Bromley school conversion, delivering a compliant underground network to support luxury residential flats.

The Challenge
This project involved converting a former school building into two luxury residential flats, but there was no existing drainage system in place. A completely new network had to be designed and installed from scratch to support multiple bathrooms, kitchens, and utility areas. ‘
The age and structure of the building required careful excavation to avoid damage, while tight site access and ongoing construction demanded precise coordination. The system also needed to be future-proofed to ensure reliable long-term performance for modern residential use.
Our Solution
BN Drainage provided a full drainage design and installation service tailored to the development. We assessed the building layout and designed an efficient underground foul drainage system to serve all planned facilities.
Our team installed new underground pipework and constructed inspection chambers to ensure easy maintenance and accessibility. All pipework was installed at correct depths and gradients in full compliance with Building Regulations.
We also connected the new system safely to the main sewer network, ensuring a reliable and compliant drainage solution integrated seamlessly with the wider construction project.
The Result
The drainage installation was completed on time and to a high standard, providing the converted luxury flats with a robust and fully compliant system. The new infrastructure supports all residential requirements and ensures dependable performance.
The client now has a modern, future-ready drainage network designed for durability, reliability, and long-term use.
