NPWA Hillcrest Tank Replacement Project

About the Project:

North Penn Water Authority (NPWA) is replacing its current water tank with a new water tank on Frederick and Clear Spring Roads in the Hillcrest section of Lansdale. Replacing this tank is part of a larger infrastructure improvement project in the Hillcrest section of Lansdale that will enhance fire protection, public safety and water quality. Construction on the new tank is projected to begin in the Spring of 2019.

Benefits of the Project:

  • Enhanced fire protection and public safety for the Hillcrest community.
  • Redundancies in water service, ensuring residents and businesses will always have access to safe, reliable water.
  • Enhanced water quality in the area.
  • More consistent and reliable water pressure.
  • One part of NPWA’s ongoing infrastructure improvements planned for the Hillcrest community. 
Current Tank New Tank
  • 1,250,000 gallon Standpipe
  • 70 feet high       
  • 60 foot diameter                  
  • Electric pump provides the area with suitable water pressure.
  • Cell antenna equipment visible.
  • Oldest tank in NPWA’s system, built in 1948, nearing the end of its useful life.
  • 250,000 gallon Spheroid
  • 140 feet high
  • 44 foot diameter bowl
  • Gravity provides water pressure.
  • Cell antenna equipment less visible.
  • New tank better meets the needs of the community, costs about the same as rehabbing the current tank.

Estimated Timeline:

Construction is tentatively slated to begin in early Spring 2019 with a completion date of late Fall 2019. We will update this timeline as needed.

Q: Why will the new tank only hold 250,000 gallons compared to the current 1,250,000 gallons?
A: The antiquated design of the current stand pipe tank means that roughly 1,000,000 gallons act as a support column to hold up the topmost 250,000 gallons, which is all that is needed to serve the Hillcrest section of Lansdale.

Q: How will the new tank affect water pressure at my house? It’s good now, and with a higher tank, I don’t want it too high.
A: Pressure in most of the area will remain the same, but will be more consistent. It depends on exactly where your home is, and if there are high pressure concerns, your pressure reducing valve can be adjusted or you can install one if you don’t have one already.   

Q: Will the fire hydrants on site be changed? 
There are no immediate plans to modify the hydrants or existing site piping around the tank.

Q: Will there be a notification to neighbors prior to the start of work?
Yes, a letter will be mailed to neighbors in accordance with the Lansdale Borough requirements prior to work with the anticipated schedule and an emergency contact phone number. 

Q: Will there be lighting on site?
A: None is planned at this time. However, existing security lighting at the Booster Station will be upgraded, yet remain unobtrusive

Q: Will chemicals be injected into the water at the tank?
A: Yes, but only if needed. Chlorine is injected as needed at various points in NPWA’s distribution system to maintain water quality.

Q: Will the cell carriers charge NPWA to move their equipment from the existing tank to the new tank? 
No, there will be no charges to NPWA.
