Water scarcity is a housing problem. Infrastructure-led efficiency is the answer

By GroundBreaker

The government's 1.5 million homes target has a water problem. Research by Public First for CIWEM found that water scarcity could leave 61,600 homes unbuilt across the East and Southeast alone –  a £25 billion shortfall. In Cambridgeshire, the constraint is already live: 9,000 homes delayed and counting.

43%more homes could be built in constrained areas with a 30% improvement in water efficiency without adding to total demand.

The responses most people reach for - new reservoirs, transfer schemes - takes 10 to 15 years to deliver. The response the sector actually needs is homes built to use less water in the first place, using infrastructure that doesn't depend on occupant behaviour.

Two product categories matter most here. Smart meters and AMI give water companies the demand visibility to manage constrained networks intelligently — but only if the meter environment supports consistent connectivity. Traditional underground boundary boxes compromise signal transmission and complicate maintenance. The Groundbreaker® resolves this: a surface-mounted, wall-fixed connection point that improves AMI performance, simplifies exchange and delivers an unjointed supply pipe recognised as best practice by both Water UK and the Home Builders Federation.

The NRv2 LoFlo® addresses consumption directly. Installed between meter and manifold at construction stage, it limits per capita consumption by up to 12% annually — passively, without asking anything of the homeowner. For water companies, that's a predictable, auditable gain. For developers in stress zones, it's part of what gets planning consent over the line.

The tools exist. The question is whether they're being specified early enough to matter.
