Foster Refrigerator operates a major manufacturing facility in King’s Lynn, producing high-quality commercial refrigeration equipment. The site includes a large industrial roof structure with internal box guttering systems designed to manage rainwater runoff.
The facility’s internal box guttering presented a recurring operational risk:

Environmental Blockages
The site is heavily populated by seagulls, leading to frequent accumulation of feathers, nesting debris, and waste within the gutter system.

Overflow Risk During Heavy Rainfall
During periods of intense rainfall, the system could not cope with the volume of water

Restricted Flow Capacity
Build-up of debris reduced the effectiveness of gravity drainage

Production Impact
Overflow events resulted in water ingress into the production area, causing:
- Damage to materials and finished products
- Costly downtime and clean-up operations
A robust pumping solution was designed to support and protect the existing drainage system during peak rainfall events.
Key elements of the solution included:
The installation was carried out with minimal disruption to operations:
By implementing a targeted pumping solution using air-operated diaphragm pumps, Foster Refrigerator significantly improved the resilience of its roof drainage system. The project successfully eliminated a longstanding risk, delivering ongoing operational reliability and cost savings.
