Description

• Roof Tanks are commonly used to serve potable water for domestic use to apartments, it also preserves water to fight against fire through fire standpipe.
• The work involves the replacement of one or more rooftop water tanks, including related piping, pump controls, and any associated painting or improvements to rooftop structures. The detailed scope of work is determined based on engagement of stakeholders and the specific design for the site.
• Roof tanks at NYCHA are made with wood which prevents corrosion as well as act as good insulation. No additional insulation is required. Therefore, during the summer water remains cold and during the winter water never freezes.

Baseline
