Mundare locks down local manhole covers

This summer, Mundare took a major step towards a safer and more secure water treatment system with a rehabilitation project for local manholes.


Over the past year, Mundare Public Works supervisor Terry Zapf noticed a significant problem occuring: unauthorized parties were removing manhole covers and dumping effluent material into the Mundare wastewater treatment stream.


In addition to the safety concerns represented by the unauthorized access, the dumping had the potential to spill into the nearby treatment lagoon, resulting in undue strain on the wastewater treatment system.


Zapf knew rehabilitation of the problem manholes with traditional cast-iron frames and covers was not the answer: a more innovative solution was needed.


Mundare’s mayor, Mike Saric, found that solution at the 2012 Federation of Canadian Municipalities Sustainable Communities Conference in Ottawa, Ontario, where we introduced him to the Lifespan System®, our unique rubber manhole frame and cover system.


Installed this summer by Zapf and Operators Don Kucheraway and Lawrence Rozumniak, Lifespan solved two significant problems for Mundare Public Works. Firstly, the its locking lid prevents unauthorized access to the manhole. Secondly, the Lifespan frame and lid are watertight, which prevents rainwater from entering the collection system through the top of the manhole. Since Mundare has a separate sanitary system, a watertight solution is essential.


Another benefit is that Mundare will not need to upgrade its lift stations. The reduction in inflow will allow them to operate without having to increase capacity, therefore reducing potential capital expenditures.


In addition, the system is made of rubber, which is not adversely affected by sewer gases or road salt and is considerably less attractive to thieves, who covet cast-iron covers for their scrap value.


The rehabilitation of the Mundare manhole frames and covers is a big win for the Public Works department, which no longer has to worry about illegal dumping of effluent materials into the wastewater system or upgrading its lift stations to handle the extra capacity. In fact, Mundare now has an extra revenue stream as septic operators wishing to access the wastewater system legally must now pay a fee based on volume.
