Blenheim Palace: From Heritage Spring to High-Speed Canning

Few projects blend heritage with high-speed production quite like this one.

Blenheim Palace — birthplace of Winston Churchill, UNESCO World Heritage Site, and home to one of England's finest natural mineral water sources — needed to modernise their water operation. The existing bottling line was unreliable, output was capped, and they had ambitions to expand into canned water alongside their established glass bottle range.

They brought in James Mae and Hunter Harris.

The Challenge

Blenheim Palace Natural Mineral Water is drawn from the estate's own aquifer and bottled on-site within the palace grounds. That's a beautiful story for the label — but a logistical reality that makes any equipment project more complex than a standard factory install.

The brief had two parts:

1. A new canning line — sourced, installed, and commissioned to produce both still and carbonated water in cans. This was a new format for Blenheim, opening up retail, events, and hospitality channels that glass couldn't easily serve.

2. Replace the glass bottling line — their existing filler was causing constant breakdowns, dragging output down and creating unpredictable downtime during peak season. They needed a reliable replacement that could slot into the existing infrastructure — CO₂ lines, water connections, the lot — without a lengthy shutdown.

Our Approach

Canning Line: Source, Overhaul, Install, Commission

Working alongside James Mae Group — specialists in food and beverage construction, M&E, and refrigeration — we sourced a high-quality secondhand canning line. Buying secondhand isn't about cutting corners; it's about finding the right machine, at the right spec, at a fraction of the lead time and cost of new.

We completely overhauled the line to meet Blenheim's specific requirements: configured for their available floor space, integrated with the existing water treatment system, set up for both still and carbonated fills, and commissioned with full staff training so the team could run it independently from day one.

Current output: over 2,000 cans per hour — with the line capable of up to 6,000 cph as demand grows.

Glass Bottling Line: Seamless Swap During Scheduled Downtime

The glass line replacement was a different kind of challenge. Blenheim couldn't afford an extended shutdown — this is a production facility serving hospitality, retail, and wholesale customers year-round.

We sourced a glass bottle filling line with ROPP (Roll-On Pilfer-Proof) capper, stripped it down, overhauled every component, and planned the installation window around Blenheim's existing scheduled downtime. The new line had to integrate into the exact same physical configuration as the old one — existing CO₂ supply lines, water connections, drainage, electrical — with zero modification to the surrounding infrastructure.

Installation, integration, commissioning, and handover were completed within the downtime window.

Result: bottling output increased from approximately 2,000 bottles per hour to over 3,000 bottles per hour — a 50%+ improvement in throughput from the same footprint.

Beyond the Hardware

Equipment is only half the story. Hunter Harris is also supporting Blenheim Palace with the implementation of Standard Operating Procedures (SOPs) across their water production operation — ensuring the team has documented processes for cleaning, changeovers, quality checks, and maintenance. Good SOPs don't just protect product quality; they protect the people running the line.

The Numbers

| Metric | Before | After | |--------|--------|-------| | Glass bottling speed | ~2,000 bottles/hour | 3,000+ bottles/hour | | Canning capability | None | 2,000+ cans/hour (up to 6,000 cph) | | Formats available | Glass only | Glass + Cans (still & carbonated) | | Unplanned downtime | Frequent (old line failures) | Minimal (overhauled, reliable equipment) |

Why Secondhand Equipment Makes Sense

There's a perception that secondhand means second-best. In food and beverage manufacturing, that's often wrong.

A well-sourced, professionally overhauled machine can deliver:

• 60–70% lower capital cost compared to buying new
• Weeks, not months of lead time — no 6-month factory build queue
• Proven reliability — these machines have run millions of cycles; the failure modes are known and fixable
• Customisation — an overhaul is the perfect time to modify a machine for your specific requirements

The key is knowing what to buy, how to assess condition, and having the engineering capability to strip, rebuild, and commission to a production-ready standard. That's what Hunter Harris does.
