SDS compact water recovery and reuse system selected for central London heritage redevelopment.

Overview
Creed Court, located on Ludgate Hill opposite St Paul’s Cathedral, is a sensitive heritage redevelopment that is now home to the Lost Property Hotel, part of Hilton’s Curio Collection. The project required a compact water management solution to support sustainability ambitions, reduce potable water consumption, and manage stormwater within a constrained city-centre site, all in line with London Plan requirements.

What They Did
SDS designed and installed a bespoke grey water recycling system paired with a 36m³ GRP storage tank controlled by Intellistorm®. The system treats up to 1m³ per hour of water from showers, baths and washbasins, supplying water for non-potable uses such as toilet flushing. Intellistorm® actively manages stormwater by monitoring weather forecasts and pre-emptively releasing water to maintain tank storage capacity during rainfall events. The system’s compact footprint allowed installation within the restricted internal plant space, with all parts and equipment deliveries coordinated around narrow streets and heritage constraints.

Results
The combined rainwater and greywater system provides major reductions in mains water use while strengthening the site’s stormwater management. Designed to work within the constraints of a heritage-listed building, it supports day-to-day hotel operations without disruption. By coupling intelligent reuse with proactive stormwater control, the Lost Property Hotel achieves its sustainability goals, lowers its environmental impact, and showcases how smart water infrastructure can thrive in complex urban settings.

"The system delivers significant potable water savings and improves stormwater resilience without compromising the building’s protected structure or operations. By enabling intelligent water reuse and pre-emptive stormwater management, the Lost Property Hotel now meets sustainability targets, reduces its environmental footprint, and demonstrates the role of smart infrastructure."
