The arms were officially granted on May 8, 1975.

The waves represent the Rivers Derwent, Deerness and Browney and the Lanchester Eagle refers to the historic Roman associations of Dare Street, Longoviciurn (Lanchester), Vindomora (Ebehester) and Stanley. The three crosses of St. Cuthbert allude to the associations of the three constituent districts with Durham's patron saint.

The crest with Lanchester's pick and Consett's flames and swords symbolise the steel industry, while Stanley's Roman shield with black field and roundels and gold thunderbolt stands for coalmining and the broadcasting station at Pontop Pike.

Adapted from Horace, the motto means 'Until the river ceases to flow' and refers to the Derwent's importance to Derwentside District, indicated by the two D's.
