Maddison Water Technology was contracted by DB Cargo at the end of 2019 to provide a dust control solution to the proposed redevelopment works for the new rail freight terminal in Cricklewood, North London.  The new 150-hectare development has been divided into four plots to provide storage and handling of large volumes of aggregates and spoil into and out of the capital, supporting major construction projects like HS2 and the ongoing regeneration of Brent Cross.



A fully automated dust suppression system was required on two plots used for aggregate and spoil storage to meet the requirements of the planning application to mitigate potential dust issues for local businesses and residents.  

Maddison Water Technology undertook the supply and installation of independent dust suppression systems to each plot, completing the works on time in March 2020.  Each system comprises of a water storage tank, pumping system and pole-mounted rainguns controlled by an automatic control system located within the weighbridge.

Our system doesn’t just provide environmental benefits of dust control but also has a green aspect utilizing an underground spring to provide a primary source of water feeding the dust suppression systems.  A boosted groundwater transfer system feeds CAT5 protected water storage tanks on both plots with the provision to extend to further plots in future. 


Recycling Depots

Site No1 London Borough of Harrow (Manual System)
MWT have installed a Dust Suppression for the above client at Waste, Refuse and Recycling Centre in Wealdstone.
The system includes 3 x R6S Rainguns mounted above the refuse which is being recycled the systems is connected to the existing mains water supply with the necessary WRAS approved double check valve installation. The system is operated manually via lever operated valves when required as the site is used by the general public we have installed a lockable master valve which will stop any unauthorized people from operating the system.

Site No2 Wolverhampton Site (Automatic System)
MWT supplied and installed 2 x R25S Rainguns mounted upon the top of the picking shed with a throw of 30mtrs in still air condition in high winds this will change accordingly. Each Raingun was fitted with a 24v AC solenoid valve and each Raingun will be operated separately on a 2 station controller. 7.5kw three phase pump will be fitted at the existing storage tank which will be controlled via a pressure switch, 90mm HPPE mains will run from the pump to the Rainguns.

The system will operate as follows:
The controller will open the solenoid valve thus dropping the pressure in the pipe from the pump unit which in turn will start the pump (From the pressure switch) when both Solenoid valves have closed the pressure in the pipework will rise and therefore will stop the pump which is now on standby until the system is required again.


Micronclean Water Storage Tank

MWT was asked by Micronclean Ltd to quote for a water storage to replace their old sectional galvanised tank which was now unsafe as Microclean need the water for the laundry factory in the week. MWT would arranged for the work to be done over the weekend.

Our engineers went in on Friday morning to prep for the works when the factory stop using the water on lunch time on the Friday, we dismantled the old tank (and placed into skips ), pressure washed the existing concrete base, erected a new 90M3 galvanised sectional water storage fitted with Greenseal liner & sectional steel cover, reconnect existing water supply & pump suction,  new tank was back in use by Saturday afternoon.

MWT supply all types of storage tanks to suit any application.

We were delighted when Mick from Micronclean gave us feedback…

“Good Morning Gents, A big thank you for a great job done ,tank looks good , your lads worked hard to get job done”

Redbridge Culture & Leisure

Maddison Water Technology Ltd have worked with the above for many years installing and looking after their Bowling Green Irrigation Systems.

We were contacted to try and find a solution for the proposed new allotments which had no water or electricity on the site.

We suggested initially sinking a 4” (100mm) borehole to find out if in fact there was sufficient water on site, we arranged for this to be undertaken to a depth of 15mtrs (You are allowed to abstract 20m3 of water per day without having to have an abstraction license) water was found so we proceeded to install a small submersible pump unit which would transfer the water from the borehole into a 22m3 polyethylene water storage tank.

The submersible pump is powered by using solar/wind power. The water from the tank will be used to water crops on the allotments.

MWT completed the whole project including installing palisade security fencing as a compound.

Network Rail – Dust Suppression

Maddison Water Technology was contracted to supply and install a new Dust Suppression System at Network Rail Crewe NDS.

The existing dust suppression system at Crewe NDS is approximately 10 years old and is currently non-operational. To bring the system back into operation would require substantial remedial works, including additional modifications to bring the system into compliance with the Water Supply Regulations and L8

The Control of legionella bacteria in Water Systems. Therefore it has been decided to replace it with a new fully compliant dust suppression system.
