We were recently approached by a company providing water and waste water services to outdoor musical events, festivals and large social events. They were experiencing problems with their existing pumps, used to take waste water from catering trucks, in that they were blocking which resulted in spillage from the transfer containers. We proposed an alternative pump which was trialled at a recent event in Hyde Park and the result was not one occurrence of spillage or overflow. The second trial will take place at Clapham Common this weekend and we will report back on the results of this.
