Birmingham-based Catalyst Corporate Finance has advised on the sale of Pims Group, a UK waste water support services business.

Established in 1972, it comprises Pims Pumps, dealing with design, installation and commissioning, and Pims Services, which handles maintenance and service contracts.

The business has operations in Stoke on Trent and Farnborough and provides domestic and commercial sewage and rainwater pump systems and services throughout the UK to clients including Tesco, Persimmon, Sainsburys and McAlpine.

Turnover is £20 million and the firm employs 200 people. The value of the deal has not been disclosed.

Catalyst said Pims operated in a fragmented marketplace estimated to be worth about £725 million in 2007 with few competitors of similar scale and coverage. The marketplace rises to £1 billion when service, installation and consultancy services are added to product sales.
