REHABILITATION OF THE BOREHOLE FACILITY AND THE PANTIN STORAGE TANKS

CUSTOMER: GREATER PARIS WATER AUTHORITY
LOCATION: PANTIN (department of SEINE SAINT DENIS)
Missions:
  • Retrofit the new Ypresian boreholes (3 wells delivering 70 m³/h each)
  • Rehabilitate the borehole water treatment equipment. Only 5 of the original filter tanks from the former facility have been kept (increase treatment flow rate from 70 m³/h to 360 m³/h)
  • Install disinfection equipment for borehole water and an in-line chlorination system on the Cartier Bresson St. 1200 mm feeder (discharge, storage 2 x 2 m³, dosage)
  • Replace lift station machinery (3 pumps with nominal output of 270 m³/h)
  • Renovate the interior and exterior waterproofing of the 2 underground storage tanks (2 x 1,500 m³)
  • Replace the pipelines and cabling with its protective sheathing, drawpits and manholes buried on the site
  • Replace the electrical and the process automation equipment required for the plant to operate properly
  • Completely restore the exterior of the building (in accordance with the stipulations of the ABF [historic buildings council for France]) and refurbish the interior (floor, walls, ceiling, windows, doors) of all the premises
  • Carry out landscaping and outside work, including the roads, planting vegetation over the storage tanks and other miscellaneous external services
  • Connect the facility's disinfection system to the feeder's chlorination chamber situated about 200 m from the plant's precincts, at the junction of Cartier Bresson St. and Avenue du Général Leclerc.
The F&M solution:

Borehole equipment requires in-depth hydro-geological assessment, and analysis of the physico-chemical properties of the groundwater. At FELJAS & MASSON, the Design and Engineering Office determines the equipment that accommodates these constraints and satisfies the correct operating requirements of the boreholes.

Key data:
  • 3 wells, each delivering 70 m³/h
  • Increase in processing rate from 70 m³/h to 360 m³/h
