Tenders Are Invited For Ancillary Works For Water Pipelines – Rehabilitation Work On The Drinking And Non-Potable Water Galleries Of Eau De Paris

Ancillary Works For Water Pipelines – Rehabilitation Work On The Drinking And Non-Potable Water Galleries Of Eau De Paris. The Consultation Concerns The Services Of Rehabilitation Works Of The Drinking And Non-Potable Water Galleries Of Eau De Paris. Eau De Paris Manages A Heritage Of Around 140 Km Of Galleries Which House Drinking Water And Non-Potable Water Pipes. These Are Mainly Visitable Works Made Of Millstone Masonry (But Also Concrete) Which Are Connected To The Parisian Sanitation Network. The Water Galleries Are Mainly Located In Paris Itself (75) But A Small Part (Connecting Galleries Between The Treatment Plants And The Reservoirs) Is Located In The Inner Suburbs (Departments Of Hauts De Seine And Val De Marne). The Objectives Of This Work Are: - To Structurally And Sustainably Strengthen The Galleries Housing The Water Pipes; - To Prevent Or Remedy Possible Subsidence Of Galleries; - Unseat The Structure And Improve The Flow Of Stray Water Into These Galleries In Order To Avoid The Risk Of Destabilization Of The Surrounding Soil)
