The Operational Challenge
Passive Rainwater Storage Is No Longer Sufficient
For organisations managing SuDS obligations, housing drainage, or public-sector estate water use, traditional rainwater collectors provide no real-time visibility, no automated control, and no evidence trail.
Overflow Before Storm Events
Without weather-forecast integration, rainwater collectors fill to capacity and overflow before incoming rainfall arrives, wasting stormwater storage capacity and potentially contributing to localised drainage stress rather than reducing it.
No Remote Visibility
Estates and facilities teams managing multiple sites cannot check storage levels remotely, respond to overflow risk, or produce water-use evidence for sustainability reporting without manual inspection visits across every location.
No Automation or Intelligence
Standard rainwater harvesting systems are entirely passive. There is no automated release logic, no weather intelligence, no alert capability, and no integration with site management platforms or compliance reporting systems.

Smart water butts explained
What is a smart water butt?
A smart water butt is a rainwater butt fitted with a level sensor, a motorised release valve and a data connection. It reports how full it is and can release water ahead of forecast rain, so there is space to catch the storm when it arrives.
| Standard water butt | AQUAIOT Smart Water Butt | |
|---|---|---|
| How full is it? | Only known by lifting the lid. | Live level for each unit on the dashboard. |
| Before heavy rain | Can already be full, so new rain overflows. | Releases ahead of forecast rain in Weather Smart mode, with a notification first. |
| Control | A tap, opened by hand. | App control, threshold rules or forecast rules. |
| Power and connection | None. | Battery powered on WiFi, 4G or LoRaWAN, with up to 7 years of battery life on LoRaWAN. |
| Records | None. | Timestamped levels, releases and alerts, exportable for SuDS and sustainability reports. |
Surface water is the most widespread source of flood risk in England. The Environment Agency’s 2024 national assessment puts about 4.6 million properties in areas at risk from it. A butt that is empty when rain starts holds back the runoff from its roof. One that is already full holds none.
Stored rainwater also takes demand off the mains. The Environmental Targets (Water) (England) Regulations 2023 require the public water supplied per person in England to be at least 20% lower by 31 March 2038 than in 2019 to 2020.

Common Questions
What Organisations Ask Us
The AquaIoT Smart Water Butt connects to UK hyperlocal weather forecast data via WiFi or 4G. When significant rainfall is predicted within the next 24–48 hours, the device automatically opens the release valve to restore storage capacity — ensuring the Smart Water Butt is ready to attenuate the incoming storm event rather than overflow into drainage. This directly supports SuDS scheme attenuation performance, planning condition compliance, and stormwater management objectives. Every automated release is logged with a timestamped record for evidence and reporting purposes.
Yes — the AquaIoT Smart Water Butt is designed for fleet and programme deployment. Multiple Smart Water Butt units across different sites, housing schemes, or construction phases can be managed from a single AquaIoT dashboard with role-based access, site grouping, and centralised reporting. Councils, housing associations, and estate management teams regularly deploy units across entire programmes rather than individual locations. Our team will advise on the right connectivity and deployment configuration for your scheme.
The AquaIoT Smart Water Butt supports WiFi, built-in 4G, and LoRaWAN® connectivity — no site IT infrastructure changes are required. For construction sites, remote locations, and properties without reliable WiFi, 4G or LoRaWAN® operate entirely independently of site networks. LoRaWAN® is particularly suited to large-scale and rural deployments, providing coverage across several kilometres and up to 7 years of battery life without mains power. Each Smart Water Butt unit can be individually configured for the connectivity type best suited to its location.
The AquaIoT Smart Water Butt sensor and valve assembly is designed to retrofit to virtually any standard UK rainwater collector — from 100L slimline units to 500L barrel-style vessels — using a universal mounting bracket and connection kit. No civils, pipe cutting, or specialist installation is required. Get in touch and our team will confirm compatibility with your specific vessel types and configurations before you commit to a deployment.
Yes. The AquaIoT dashboard provides a complete timestamped log of level readings, automated releases, and alerts for every Smart Water Butt unit in your deployment. This data is exportable and can support sustainability reporting, SuDS scheme evidence for planning authorities, estate water-use reporting, and environmental performance reviews. Our team can also discuss API and platform integration for organisations that need to feed data into existing CAFM, AIMS, or reporting systems.
Yes — the AquaIoT Smart Water Butt is available for individual property owners as well as organisations managing multiple sites. The same weather-intelligent technology, three-mode control system, and real-time monitoring capability applies whether you're installing a single Smart Water Butt or rolling out across a hundred-unit housing scheme. Get in touch and we'll discuss the right configuration for your setup.
Contact the AquaIoT team via our enquiry form and we will arrange a consultation. We will discuss your scheme size, existing vessel inventory, connectivity requirements, SuDS obligations, and reporting needs — then advise on the right Smart Water Butt deployment configuration for your programme. We support everything from single-site pilots to large multi-site rollouts, and can provide compatibility confirmation, pricing, and deployment planning before you commit.
Funding changes often and depends on where you are. Water companies, councils and community funds have all supported water butts and rainwater projects. Our guide to UK water management grants lists the schemes we know of and how to check what is open in your area.
No. It runs on battery and connects over WiFi, 4G or LoRaWAN. On LoRaWAN the battery lasts up to 7 years, so it suits construction compounds, remote sites and unpowered locations with no power or IT connection.
Rainwater smart control means the release valve opens on a rule instead of by hand. You can set a release level and a low-level alert, or let the butt read the forecast and release ahead of heavy rain. Every release is logged, and a notification goes out before an automatic one.
