IWJS, an operating business of M Group Services, has signed contract extensions to continue delivering essential works at Heathrow Airport and Addenbrooke’s Hospital.

At Heathrow Airport, IWJS will continue in its role as Tier 1 drainage supplier, delivering corrective and planned maintenance on drainage systems in terminals 2, 3, 4 & 5. This will include maintenance on landside and airside drainage systems across the airport, including petrol and oil interceptors, pump stations and all foul and surface water drainage systems.

The contract includes 24-hour emergency response, with a two-hour response time commitment.

The IWJS team at Iver has been servicing Heathrow every day for the past seven years. The team was recently voted as contractor of the month following the successful installation of a difficult repair to the fire main.

The company has also announced a five-year extension to continue delivering site drainage maintenance and repair services at Addenbrooke’s Hospital in Cambridge. IWJS has been providing the services for the past eight years, bringing the partnership to a total of 13 years working together when this contract ends in 2027.

The core scope of works for IWJS will include planned preventative maintenance, site surface drain jetting, including foul drains and radioactive drains.

Peter Maasz, IWJS Business Development Director, said:

“We are delighted to have been awarded these contract extensions by two of our long-standing clients. The awards are testament to the continuous commitment of our people to deliver high-quality, essential works which are crucial to the successful operations of both Heathrow Airport and Addenbrooke’s Hospital.”
