Installing a Flood Water Sensor Alarm in your basement or low down on an outside wall or step is a great way to be alerted if the water levels are rising.
In the 2020 report “ State of the UK Climate” the UK Met Office says that the UK has become wetter over the last few decades. 2011 to 2020 was 9% wetter than 1961-1990 for example. With both rainfall frequency and intensity increasing across the UK.
The risk is that increased frequency and intensity of rainfall from events in summer will increase the severity of surface water flooding, particularly in urban areas, which could lead to a greater risk of flash flooding. Summer rainfall events are particularly concerning because for every 1oC more that the air warms it can hold about 7% more water which means that when the rain falls there is much more of it.
We have seen in the recent years that properties that are on a flood plain are being more severely flooded and that properties that historically have not been affected by flooding at all, have been affected by heavy rainfall events when drains have been overwhelmed or riverbanks have burst.
This RKIT1 Flood Water Sensor Alarm Kit is designed to be a flood early warning system to give you time to install flood defences, activate drainage pump systems and move vehicles, furniture, and valuable objects.
The RKIT1 kit includes a REKA water sensor that has no moving parts and is only triggered when the arms of the REKA sensor are immersed in water (protection rating IP68). The sensor can be installed outside, on steps or any outside structure near a water course or point of flooding (as well as in a basement). Rain or splashing will not trigger a false alarm.
The flood alarm box is splash resistant (IP65) and therefore needs to be installed indoors and above the height of the REKA water sensor. The 10m cable supplied with the sensor enables the flood alarm box to be installed in an appropriate location.
Before installation, the 10m cable on the REKA can be cut to an appropriate length if required. There are snap connectors inside the alarm box to easily connect the REKA’s wires to the alarm box (which should be done by a competent person).
Once installed, the flood alarm box is easy to use. When plugged in a green light shows (to show the box is powered). When the water level reaches about 3cm up the REKA sensor, the red light will turn on and an 80 decibel alarm will sound. There is also a switch to disable or silence the alarm.
The Flood Water Sensor Alarm described here (RKIT1) is mains powered with audible and visual alarms. If you are interested in an off-grid option (24v), different cable lengths, or flood warnings via text alert or radio link please contact us with your requirements.
If you haven’t yet delved in the world of downpipes and guttering in the UK you might be amazed to find out that it is quite a complex world of different materials and sizes. To cut a long story short, there is no standard size. We started to make a list of downpipe sizes from [...]
How to improve water pump efficiency is a subject every homeowner with a rainwater harvesting system, farmer pumping water for livestock or agriculture and facilities manager are keen to understand more about. Our technical team has many years’ experience of advising tradespeople and end-users alike about how they can help ensure their pump lasts longer [...]
What we need is a simple battery operated water level indicator is the cry from online forums! It seems that many motorhome and caravan owners often run into issues with their regular water level sensors. The common problem seems to be that regaulr water level sensors either they stop working, always show as empty or [...]
With water shortages and the cost of mains water increasing year on year, many homeowners and businesses are looking towards the Government for help with funding. The good news is that for systems that fit the criteria there are Rainwater Harvesting Grants and Water Capital Grants available in the UK.At this time, however there are [...]
As the world is increasingly aware of plastic in the ocean and the problems that is causing, many of us are reducing our use of single use plastic, trying to shop plastic free in the supermarket veg aisles and taking part in beach cleans. We try and do our bit, but what about the rest [...]
DEFRA’s recently published progress report on the Government’s 25-Year Plan for the Environment, makes interesting reading for any builder or self-builder, not least where it relates to water. Acknowledging existing stresses on water supplies, and the additional increased pressures likely to arise in coming years from population growth and climate-change, one of the key [...]
We have compiled some answers to some common questions about gardening in hot weather.How do you keep your grass green in the Summer? Don’t cut your grass too short Your lawn will get stressed in hot weather and it also gets stressed when it is cut short. You can’t do much about the weather (especially [...]
Rainwater Harvesting for use in the home, in agriculture, office and other commercial environments is becoming more popular. Storing rainwater for later use can reduce water and sewage bills and allow you to water a garden during a hosepipe ban with gentler rainwater rather than treated tap water. Using rainwater in a washing machine or in [...]
Upstream water attenuation is part of a range of solutions to flooding, even better if it can be combined with wildlife friendly gardening. In this first in a series of blog posts about Sustainable Drainage Systems (SuDS) we look at the role of Rain Gardens in Flood Mitigation. The term “Rain Garden” has changed over the years. Technically it has [...]
