nhs plant room leak detection system in situ


A well known NHS Health Trust based in the South West selected Envirotech Alarms to supply all their plant rooms with water leak detection.nhs plant room leak detection system in situ

Reacting to several occasions where water leaks had gone unnoticed and the resulting damage caused disturbance to the running of the building. They took the decision to install a complete water leak detection system to give them immediate knowledge that a leak had occurred.

Sensor tape, designed to trigger an alarm when water touched any part of it was used. The area immediately around the Air Handling Units, Boilers, Chillers, Heat Exchangers, Tanks and Pumps had tape laid around them. Each area was connected back to a LeakStopper 8 multizone alarm panel that allowed them to quickly see which piece of equipment had a leak.

Out of hours alerts where handled by adding an SMS text dialler that sent a message should the alarm panel detect a leak on any of the zones.
Envirotech Alarms where chosen as the preferred supplier due to their ability to design a bespoke water leak detection system to suit each of the 5 different sites requiring protection.

Tea Point Leak Detection Case Study

We were recently approached by the Environment Agency to price and then supply a Tea Point water leak detetction package for their offices in Leeds. This followed a problem with a macerator positioned under the sink that caused a leak into the offices below.leak detector is not visible in the kitchen

In order to ensure that there wouldn’t be a repeat of this situation, a leak detection system was needed. This had to immediately pick up the presence of water in the area and simultaniously switch off the water supply.

When the Environment Agency contacted us it was clear that the TeaPoint package was the best solution. It contains everything required to detect water, sound an alarm and switch off the water using a solenoid valve.

The benefits of buying the Tea Point package meant they received everything required to install a water leak detection system and be protected quickly and easily. Envirotech Alarms Ltd supply a range of complete leak detection packages, however in this instance the tea point one was the most suitable.

Tea Points can be particularly vulnerable areas where water leaks can occur. They are often situated on upper floors and any leaks would permiate down to the floor below. Damage limitation and peace of mind are achieved when fitting a Tea Point package and can often be a requirement of the buildings landlord.

This very popular water leak detection package has been used in many installations and has been proven to be an easy fit and forget solution.

 New Pump Control Panels

Envirotech Alarms are pleased to inform you that we now have a great range of pump control panels for the control and protection of submersible pumps used in packaged pump stations.

We have pump control panels for use with dual pumping stations as well as a single pump version. All our control panels offer reassuring protection against short circuit and overload problems as well as flexible pump control at the most competitive prices. Our duel pump panel has an alternating pump control feature that will automatically switch between the two pumps reducing long duty cycles. This offers greater protection for each pump as the length of time they are in continuous use is greatly reduced. Whenever a pump is called for to start pumping liquid, this will remain running until the levels drop to a satisfactory level. The next time the levels rise and a pump is required to start, it will be the other that comes on. This alternating pump switching is continued every time the fluid levels rise and fall in the tank. Should for any reason the levels rise to a critically high amount, both pumps will automatically kick in to eject the liquid at a higher volume and much faster.

pump control panel - alternating control boxAll the panels use solid state technology as apposed to PCB electronics allowing the installation of any spare parts to be easy and low cost. There are 240V and 400V versions available and any submersible pumps can be connected to them regardless of the current rating required. Pump overload protection is achieved using a suitably rated overload relay that will switch should a problem occur and the pump tries to draw more current that what it’s been designed for. Should the pump overload the alarm panels will shut down the power to it and show the problem via a warning light and sounder.

All panels have manual override and pump off facilities as well as the capability to connect to SMS text diallers and land line voice messaging alarms. Incorporating a system that can automatically send a text or voice message should a problem occur is especially useful when a quick response is required or the premises with the packaged pump station isn’t always occupied.

A recent project for a luxury housing complex in Barbados

This required dual pump control connected to SMS text diallers. As the properties weren’t permanently occupied it was critical that any problems could be highlighted immediately and a local tradesperson instructed to visit the house. Each property had a multi state sewage treatment plant installed that required an air compressor to pump air into one or more of the chambers and two heavy duty submersible pumps. The dual pump control panel was selected and connected to a series of float switches that defined when the liquid levels were such that the pumps started and to detect if there was a high level issue. In addition to this a relay was included that when connected to the signal output on the air blower would send an alarm on pressure drop. Both the high level alarm and the pressure loss alarm where linked to an SMS text dialler that had been set up to send a bespoke message depending on what the problem was.

Envirotech Alarms pump control panels are competitively priced, use solid state technology and we hold a good stock for fast delivery, contact us to find out more.

leak hunter 1 oil leak panel


The Project:leakhunter 1 oil leak panel

To protect the basement area in a large commercial office building in central London. The client was an international specialist consultancy providing integrated services and facilities management. As part of their facilities management portfolio they offer their clients a service to maintain safe and risk adverse environments, this oil leak detection project formed part of this service.

The Requirements:

The basement houses 2 very large backup generators and a diesel fuel tank. An early warning system was required to alert that a leak has occurred either from the tank or the connecting pipes needed to be fitted. A trench had been fabricated in to the floor of the basement in which the pipework ran.

Envirotech Alarms were asked to provide a complete solution that would detect the presence of diesel fuel oil within the trench. Should a leak be detected an alarm would be raised on the panel and also on the BMS (Building Management System). Envirotech Alarms proposed the LeakHunter 1 single zone oil leak detection alarm panel and their oil leak detection probes.

The probes supplied for oil leak detection use a clever optical technology that’s capable of detecting a wide range of different liquids. These include refined and unrefined oils, pure water and some acids to name but a few.

The Solution:oil leak sensorleak sensor

Installation took place out of hours as any drilling during the working day would be disruptive. The panel was mounted on a wall in the basement and power provided via a 230VAC fused spur. A connection cable (supplied) between the panel and the first sensor position was routed through containment. The first sensor was connected and the connection cable then run from this point to the next sensor. This process was repeated until 5 sensors had been connected in series. A slight amendment to the sensors took place during manufacturing that allowed the actual sensing element to sit underneath the sensor housing. This allowed the sensors to be low profile and more suited to being installed in the trench where the pipes ran.

Once installation had been completed and everything had been checked through the system was powered up. Tests were made on each of the 5 sensors to ensure that should a leak occur the alarm panel would trigger an audible and visual signal. A connection to the BMS was made using one of the volt free relays in the alarm panel. This connection and the resulting BMS reaction was also tested.

The Project:

The Passage, St. Vincent’s Centre, Carlisle Place, London.

The Passage Resource Centre, offers homelessness prevention and community schemes, as well as frontline services for those on the streets, such as primary services (food, showers, clothing), primary healthcare facilities, mental health and drug and alcohol services, and employment, training and welfare rights.The Passage in London

The community of Daughters of Charity, who arrived in Carlisle Place in 1863 and have provided much needed services to those in that area since, including establishing The Passage in 1980.

For many years the building fabric of St. Vincent’s Centre has been in a terrible state of disrepair; threatening the sustainability of these services. However, after raising funds from individuals, Trusts and the construction industry it is being refurbished.

Upon completion The Passage will have completely refurbished residential and day services facilities in the St. Vincent’s Centre to match the high quality of service provided for those most in need.

The Requirement:

As with most new build and refurbishment projects in London, there was a requirement to meet a minimum of BREEAM “Very Good”.  Part of this project was to install a major water leak detection system that covered the requirements listed in WAT03 of the BREEAM guidance notes.  In order to achieve the credits available for this section a water meter had to be fitted on the MCWS that can monitor the flow of water into the building.  A control panel that could recognise abnormal levels of water use connects to the water meter and continuously monitors for leaks.  ISG, the main contractor for this project instructed RMS (the mechanical subcontractor) to select a supplier for the major water leak detection equipment.  RMS selected a LeakSaver1 system from Envirotech Alarms Ltd as the most suitable to meet the BREEAM requirements.

The Solution:

Installing the alarm panelA single zone major water leak detection system has been installed at The Passage.  A single zone version has been used as the MCWS comes straight into the building from the street and there is essentially no external pipework from the boundary to the building.  A 65mm PN16 flanged cold water meter with a 1:10 pulse reader has been installed where the MCWS pipe enters the building.  In addition to this there is a 65mm motorised butterfly valve that will automatically shut the water off should a leak be detected (The valve is an option and does not form part of the requirement for BREEAM).  A LeakSaver1 alarm panel has been fitted in the main water intake room and the meter and valve connected to this.  In early August on a typically rainy summers day, Envirotech Alarms went to site to commission the system.  This involved setting up a number of parameters that are used as references against which water usage gets monitored.  There are two main elements to this, the amount of water expected to be used and at what time of day these    amounts will be used.  In the case of The Passage, it was calculated that on average 9,500 litres of water would be used per day (this figure was offered by the consultants).  The LeakSaver1 system calculates water usage in litres per half an hour, so at the most basic level, a threshold of 200 litres per half hour could be used (9,500/48).  Unfortunately it’s notWater Meter in the Passage quite that simple and the usage rates at different times of the day and night need to be factored in.  Naturally there will be more water used in the day than at night in this type of building, as well as certain peak periods during the day to consider such as the build up to lunchtime.  Without any historical data being available on water usage, it is difficult to enter an accurate figure.  In this case we took the approach that of the 9,500 litres of water used in a day, the largest percentage would be used between 8am and 8pm and within this time period, there would be a peak around 11.00am to 1.00pm.  Taking this peak as a worse case scenario we calculated that as much as 700 litres of water could be used in a half an hour.  Once we added in a small tolerance, we set the system to look for 1,000 litres and should this amount be exceeded, it would most likely be a leak and the alarm would trigger.  Once the building is up and running properly, a better understanding of the consumption will be gained and the threshold amount can be easily adjusted to suit.

The Project:

The Inspire Academy in Ashton Under Lyne has been built to meet rising demand for school places in the area.

It’s one of 2 schools being built that will eventually provide places for 800 studentsThe Inspire Acadamy in Ashton Under Lyne including 52 nursery places.  The Inspire Academy has been deliberately sited in an area where demand for places is expected to rise sharply due to increases in the birth rates since 2006.  The Government funded £ 8m for both academies on the provision that they are also sponsored.  The Carillion Academies Trust will work with the schools to bring about support and mentoring to help inspire, support, motivate and help students achieve their aspirations and goals.

The Requirement:

As with most new build and refurbishment projects funded by the Government, there was a requirement to meet a minimum of BREEAM “Very Good”.  Part of this project was to install a major water leak detection system that covered the requirements listed in WAT03 of the BREEAM guidance notes.  In order to achieve the credits available for this section a water meter had to be fitted on the MCWS at the boundary of the building and other where the pipework entered the building plant room.  A control panel that could recognise abnormal levels of water use connects to the water meters and continuously monitors for leaks.  The Vaughan Group, the BMS contractor for this project selected Envirotech Alarms Ltd as the company most suitable to meet the BREEAM requirements.

The Solution:

Alarm panel mounted in plant roomThe LeakSaver two zone major water leak detection system has been installed at the academy.  A two zone version has been used as the MCWS runs under ground from the boundary (there is a meter pit housing the authority meter and a secondary pulsed output water meter, situated on the public path adjacent to the school).  A 40mm cold water meter with a 1:5 pulse reader has been installed in the external meter pit and a 50mm PN16 flanged water meter with a 1:10 pulse reader fitted in the plant room (see photo below).  A LeakSaver2 alarm panel has been fitted to the BMS panel and the two meters connected to this. Handover of the school was at the end of August in time for the start of the new Water Meter in Pipeacademic year. As part of the final works before handover, the LeakSaver2 needed to be commissioned.  This involved setting up a number of parameters that are used as references against which water usage is monitored.  There are two main elements to this, the amount of water expected to be used and at what time of day these  amounts will be used.  In the case of The Inspire Academy, it was suggested that on average 6,500 litres of water would be used per day (this figure was offered by the client) with this figure dropping to only 300 litres when the building is unoccupied.  The LeakSaver2 system calculates water usage in litres per half an hour, so a threshold of 295 litres per half hour was used (6,500/11)/2.  This calculates the water use over the 11 hours the school is open and breaks it into ½ hour intervals. We now had a figure we could use for day time use and another for night time use.  This allowed us to set the alarm panel up to look for a flow of 295 litres of water in any half hour period between 7.30am and 6.30pm and to look for 12 litres of water in any half hour period between 6.30pm and 7.30am (a small contingency has been added to both amounts to allow for unexpected circumstances such as parent evenings).  Should the flow of water exceed either of these amounts, the alarm panel will go into alarm sounding a buzzer illuminating an LCD screen that a leak has been detected and signalling to the BMS.  Finally, the out of hours parameters needed to be set to cover the entire weekends as the school would be unoccupied during this time.  The LeakSaver2 panel has a feature that allows this to be set up quickly and easily.
