Efficient Pumping Solutions for a Premier London Restaurant

Background

Located opposite Trafalgar Square and Nelson’s Column, the newly opened Strand Dining Rooms sets out to become one of London’s premier themed restaurants – styled on the elegance of a traditional Pullman Coach. With a full-service offer from breakfast through to dinner, the venue is designed for high footfall and continuous operation in the heart of the capital.

As part of the extensive basement refurbishment, the restaurant required a reliable and robust wastewater and sewage pumping system to support both the busy commercial kitchen and customer washroom facilities.

Challenge

The kitchen and washrooms are located in the basement of the building, well below street level. This presented two key challenges:

• Wastewater from the kitchen sinks and dishwashers needed to be pumped efficiently, including hot water and food solids.

• Sewage from customer WCs had to be lifted to mains level with a compact, durable solution that integrated seamlessly with the restaurant’s infrastructure.

Given the expected volume of usage and the premium location, the system had to be highly reliable, easy to maintain, and capable of integration with the restaurant’s Building Management System (BMS).

Solution

Building Services Consulting Engineers Lehding Services Design Ltd turned to Pump Technology Ltd, the UK’s leading independent pump specialist with extensive experience across retail and hospitality – supporting brands such as Costa Coffee, Pizza Hut, and KFC.

After consultation, the following solutions were specified:

Kitchen Wastewater Solution

• Drain Major and Drain King systems were installed to handle greywater from kitchen sinks and dishwashers.

• These compact under-worktop units feature Jung Pumpen pumps with fixed float-arm controls, housed within GRP tanks with easy-access lids.

• Designed for site-specific adaptability, the tanks allow inlet positioning to be adjusted during installation.

• Both systems include high-level float alarms, linked to both remote audio alarms and the BMS, with battery backup in case of mains failure.

The Drain range is fully capable of handling:

• Food solids up to 30mm (e.g., from macerators)

• Hot water discharge from commercial dishwashers (up to 90°C)

Sewage Pumping Solution

• For the diner toilets, a floor-mounted Compli micro sewage lifting station by Jung Pumpen was installed.

• This packaged offsite solution includes:

  • A compact polyethylene tank with multiple inlet options

  • Duplex vortex pumps for raw sewage

  • Non-return valve

  • Intelligent control panel for alarm alerts and BMS integration

• Available in single or three-phase options, the Compli is easy to install and ideal for confined basement spaces.

All systems were installed by K&M Technical Services Ltd, who praised the install-ready nature of the units and their compatibility with onsite layouts.

Pump Technology Ltd provided full commissioning support along with national warranty and maintenance cover for all systems. This partnership approach, involving consulting engineers, specialist contractors, and dedicated pump suppliers, ensured a smooth delivery and rapid installation.

The Strand Dining Rooms officially opened under the guidance of restaurateur Mark Harris. Thanks to the collaboration between Lehding Services Design Ltd, K&M Technical Services Ltd, and Pump Technology Ltd, the site now benefits from a fully integrated, reliable, and future-proof wastewater and sewage management system — ready to support busy service from breakfast to last orders.
