In 2021, the city of Johnstown, PA experienced severe infiltration at the casting and cone joint of a 3.17vf manhole located approximately 150’ down in a Gautier Steel Limited tunnel. How severe? At an estimated 40 gallons per minute or 2,400 gallons per hour, that equaled about 57,600 gallons in a day’s time. If the infiltration would have continued, it would have been an extra 21,024,000 gallons of unnecessary treatment for their local plant to process in a year’s time.
Here are two videos taken that day that shows what the initial infiltration looked like:
Advanced Rehabilitation Technology (ART) has a great working relationship with the city of Johnstown and has for many years. They know the problems we can handle. After we received the call from them, it took a two-man ART crew only six hours to have the infiltration stopped, completely dry, and spray-lined utilizing the OBIC Multi-Layer Liner System. The solution included:
- Grout injection to slow the water flow
- (8) OBIC 2210 cartridges
- (2) OBIC 2262 cartridges
- 10 pounds of Hydraulic Cement
- Surface preparation: pressure wash and rinse manhole
- Dry structure surface
- Applicate the OBIC Multi-Layer Liner System
Here’s a great “after” shot of what the same manhole looked like after ART’s services were complete:
As an added bonus, the liner is also covered under a 10-year L&M warranty.
What were the total savings as a result of this project? The treatment plant cost is $1.75 per 1000 gallons. 21,024,000 gallons per year divided by 1000 gallons equals 21,024 gallons. 21,024 gallons multiplied by $1.75 equals $36,792.
An impressive $36,792 was saved PER YEAR after the city of Johnstown spent about $5000 in an initial investment with us. That’s definitely a win-win for the city from our perspective!
