The Capcon ESG Index
Siphonic drainage delivers more than faster water removal. It reduces material use, supports rainwater reuse, lowers CAPEX and contributes to climate-ready building design. The Capcon ESG Index helps you see exactly where those benefits align with your ESG priorities.
What each ESG category means
Climate resiliance
The capacity of a building’s drainage infrastructure to perform reliably under increasingly extreme and unpredictable weather conditions. As rainfall intensity rises and flood events become more frequent, buildings need drainage systems designed to handle peak loads, protect assets and maintain operations without disruption.
Climate Resiliance
Compliance
The ability of a drainage system to meet the regulatory, industry and sector-specific standards that govern how buildings must perform. From GMP requirements in pharmaceutical facilities to healthcare hygiene standards and corporate ESG reporting obligations, compliant drainage is not optional — it is a fundamental requirement of responsible building design and operation.
Compliance
Net Zero Buildings
The contribution that rainwater management makes to a building’s broader sustainability targets. Siphonic drainage uses significantly less raw material than conventional systems, reduces delivery loads and site emissions and enables rainwater reuse — all of which reduce a building’s embodied and operational carbon footprint and support net zero design strategies.
Net Zero Buildings
Cost Savings
The measurable financial benefits delivered across a project’s full lifecycle, from reduced material and excavation costs at installation through to lower maintenance expenditure over time. Siphonic systems consistently outperform conventional drainage on total installed cost, and the savings compound across design coordination, construction programme and asset protection.
