Water treatment services that go the distance

Your commercial water treatment system saves you time and money in the long run. But it also requires maintenance and monitoring to continue meeting the required standards. At Excel Water, we take care of this for you.

We provide comprehensive maintenance services to keep operations running all year round. To prevent costly breakdowns, we offer boiler testing, as well as cleaning and chlorination for pipework and tanks. To manage on-site maintenance, we supply consumables and new tanks and pumps.

  • I’m happy to say that in 5 years we haven’t lost so much as an hour’s production through the demin plant. The plant produces a water quality of less than 1µ/cm which means we are able to supply our customers with a first-class product. It would be great if all my other plant were as reliable as the demin plant and that my other contractors were as reliable as Excel water are. An excellent product supported with excellent service levels. Top marks from Caldic.

  • We arranged for Ray to come to site and look at our filter system and maintenance procedures with a view to advise us on any improvements or issues he thought we should address. Ray was very professional and quickly identified several issues. This only took place a week ago but already we are seeing an improvement in the water quality and I am very confident that the changes we have introduced, based on Ray’s guidance, will continue to improve our water quality and benefit our business.

  • Excel’s engineers are very knowledgeable, whether on site or over the phone in fault finding. In one instance they confirmed over the phone where a problem originated from and how to rectify it, proving we had issues with our incoming water supply pressure. I would definitely recommend this company for plant installation or servicing of any water treatment plants.
