Whether you're a returning Clogger or new to us, welcome to all-action mental war zone that is CleverClogs - the search for the sharpest brains in the business.

Launched with the support of NCE and drainage specialist, ACO Technologies, the competition is straightforward to get involved in and offers some fantastic rewards - beyond the awe and respect of your peers that is. All you have to do is answer the appropriate questions that appear every week in NCE.

There are two leagues in this year' competition: 'A Level' and 'GCSE'. Open to individuals and teams.

The competition runs for 8 weeks: from the 22nd Sept issue through to the 10th November issue. The top teams and individuals from the A Level league will then be invited to our live Grand Final which will be held on the ACO stand at the new Civils Exhibition at Olympia. So good Luck!
