Case History: Parklane Towers

Location
   Dearborn, Michigan

Problem
The aging galvanized water distribution risers in the twin
15 story Parklane Towers had become deteriorated with
mineral build up and corrosion resulting in restricted flow
and brown water. Underground 4" pipes needed to be
restored from the pump room to the main buildings, as
well as a 4" diameter central riser servicing main
bathroom groups and four 2-1/2" galvanized graduated
to 3/4" copper tenant risers for the floors in each tower.

Traditional Restoration
   • Break slab, dig and replace underground pipe
   • Abate all asbestos contaminated areas
   • Shut down water to risers
   • Disconnect all lateral branches
   • Break our firewall for central riser re-pipe
   • Major inconvenience for tenants
