Low Pressure Systems

[raven]

In our area they have been installing these low pressure sysytems in new residential neighbourhoods when the city does not want to put in large pumpstations. Each home on the street has their own pump. Some utilize a septic tank to filter to pump station then up the street to main line (100-200 yards or so) system and others have the household waste go staight to a grinder pump then up the street to the main line system. The latter is the current preffered system. As the city gets larger there are more and more of these systems. Questions: Will these grinder pumps stand up to the average households abuse??? How often should these pump stations be cleaned?? Is the former system utilizeing the septic tank better?? I would think the tank cleaning costs occasionally would be sufficiently less $$$$ than replacing one of those pumps. Any thoughts??
