This case study describes how the Olympic Delivery Authority (ODA) set an agenda for water efficiency and embedded this in design briefs, the procurement process and contracts for buildings on the London 2012 Olympic Park.
The key learning from the ODA’s experience, which is consistent with WRAP guidance, is to:
- set a clear objective for water efficiency early in the project;
- put processes in place to deliver the water efficiency objective through design, procurement and construction;
- assess the current market for water efficient fittings and engage the design team, suppliers and contractors to pursue the most appropriate solutions;
- specify performance and flow rates, rather than percentage reductions;
- remember that there this is a practical limit to water efficiency;
- produce a Water Efficiency Plan with clear specifications for water efficient fittings; and
- put processes in place to ensure the design intent and performance requirements are understood even when the project reaches the facilities management stage – through a Water Efficiency Plan or similar.
The ODA has produced a sustainability learning legacy research paper on the Olympic Park’s water strategy, which readers should refer to for more detail.
