The ShowerSaver (trademark to be changed due to trademarking issues) is an electronic sensor and timer product that mounts onto shower piping. It influences a user to shorten their shower duration and educates them about their water and energy use and costs.
The product is a simple self-install, that does not require a technician. With a low cost and self install it has a typical ROI of <6 months.
The product does not control water flow, but rather is a behavioural measure that influences user / human behaviour providing behavioural prompts during a shower and providing insights in actual and projected energy, water and cost savings via an App.
The product sits neatly in the nexus between water and energy efficiency. With increasing water scarcity, increased reliance of energy-intensive water production (eg desalination eg WA relies on desalination for ~50% of its water) and increasing energy costs there is a growing awareness that shorter showers can have a significant impact on household costs and are a major opportunity for water and energy conservation
RRP $79 - but the product will be sold primarily directly to water/electric and gas utilities in volume with a substantial cost reduction.
