Birth : 1841[Paris]
Death : 1888
Promotion IPC : 1866
Alfred Durand-Claye, former student of the École polytechnique, left École des Ponts et Chaussées top of his class in 1866. He entered the City of Paris water, sewerage and waste management department, and dedicated the whole of his engineering career to the problem of enhancing urban hygiene by the treatment of waste.
His name is associated with the big 19th-century underground street works he conducted for 22 years after leaving Ecole des Ponts et Chaussées in 1866, following his first place at Ecole Polytechnique.Placed under the orders of Belgrand, a close collaborator of Alphand, Alfred Durand-Claye dedicated himself from the start to the question of “everything to the sewers”, in particular through the sewage fields of Gennevilliers.This previously arid plain was the location of his first project in 1867 and for the first 200 hectare trial in 1873. He successfully experimented with sewage fields for market garden crops, using filtration to purify wastewater.In 1884, more than 100,000 m³ of sewer water on an area of 800 hectares made this small village a centre of intensive market gardening for supply to Paris.These achievements had a great impact in 200 cities around the world, including Berlin.Raised by the International Hygiene Congress in Paris and inaugurated on August 10, 1894, Alfred Durand-Claye’s bust stood in Place Voltaire d’Asnières before being moved to Gennevilliers in 1926.Sculpted by Boucher, it stands on a granite pedestal where his different posts and activities are engraved, together with the words “He dedicated his science to the hygiene of cities.He was the great craftsman of the sanitisation of Paris”.A Paris street (14th arrondissement) was named after him in 1890.
