Specialist products and services to protect people and assets in the residential sector

A range of flood defence products and an automatic water supply usage monitoring and isolation system specially developed for the residential market

The Environment Agency warns that over five million properties in the UK are at risk of flooding by rivers, the sea and surface water flooding from overflowing drains. There is also a growing requirement from insurers of residential properties to have a leak detection and a flood prevention system in place.

Andel has gained a wealth of experience in the science and technology involved in the protection of the built and natural environments from water and gas leaks, oil spills and surface-water drainage problems. The business is looking to familiar, tried and tested technologies and adapting to effective flood defence and residential leak detection applications.

Flood Defence

As the frequency of flood incidents in the UK increases, there is a growing risk to properties not adequately protected by flood defences or not covered by the Environment Agency flood warning system. Andel is now investing in flood defence and warning systems to protect UK properties.

Andel has developed a range of flood defence products including Andel FloodAlert®, Andel FloodWall® and Andel FloodPump to create a proactive chain of defensive lines to allow for a timely response to flooding caused by rainfall to protect both people and assets.


Andel FloodAlert®

Andel FloodAlert® is the ideal early warning system for single and multiple properties at risk of flooding through rising groundwater

The posts can be strategically positioned to give maximum warning to allow for evasive action.

Easy to install and set up, the posts transmit warnings and real-time monitoring of water levels to a cloud-based portal, accessible from any internet enabled device, with no necessity for special software. Andel FloodAlert® uses a robust, ultrasonic LoRaWAN level sensor and integrated radio, encased in a recycled, watertight and shatter-resistant outer casing, ensuring consistent reliability. The posts can be installed up to 15 kilometres from the gateway in some cases and each gateway can connect to an unlimited number of users.
