Cutting Sanitary Wipes Down to Size

Each day, the Northline Lift Station in Laguna Woods, Calif., transports sewage generated by 33,000 domestic users to The El Toro Water District Water Recycling Plant. The wastewater treatment facility serves five cities and is one of the oldest water recycling plants in Orange County. The district has successfully kept pace with the water demands of a growing population through an innovative combination of process technologies and enhancements that promote conservation and recycling.

New York Town Tackles Clogs with Grinder Upgrade

The wastewater treatment plant in picturesque Cobleskill, N.Y., was unable to process the wastewater generated by the town's 4,678 year-round residents. The buildup of plastics, rags, trash wrappings and other debris was regularly clogging the system, necessitating frequent cleanings.

The Challenge

Screen & Grind Success

The Millbury, Mass., pumping stations are part of a regionalized consortium of eight communities that discharge their wastewater to the Upper Blackstone Water Pollution Abatement District for treatment. The 56-million-gal-per-day facility sits at the headwaters of the Blackstone River, once considered one of the most polluted river ways in the country. As a result of plant upgrades and projects, the water quality was considerably improved and the river will be swimmable by 2015.

Disintegrator Solves Ragging Problem, Eliminates Downtime

The Route 108 pumping station located in Howard County, Md., serves a large, affluent and mostly residential area. The station pumps 3.5 million gal per day (gpd) of wastewater to the Patapsco Wastewater Treatment Plant in Baltimore for further processing. When necessary, the treatment plant is bypassed and the wastewater is sent instead to the Little Patuxent Water Reclamation Plant. This arrangement, though uncommon, had worked, but one day, things took a turn for the worse.

Protecting Equipment from Abrasion, Clogging

The Pottstown, Pa., wastewater treatment plant handles the wastewater generated by 15,000 area homes, commercial businesses and industrial sites located in the borough of Pottstown and three nearby townships. The facility is rated for 15.6 million gal per day (mgd) and treats an average sewage flow of 7 mgd.

First Line of Defense for Prison Effluent

For years, Graterford Prison, a maximum-security facility in Pennsylvania, experienced continuous problems with their wastewater system. Their antiquated equipment consisted of bar screens, grinders and comminutors, which were frequently overwhelmed by the sewage generated daily by 3,600 inmates.

Pump-jamming At Correctional Facility

Inmates in correctional institutions apparently had found a new diversion. By flushing oversized items down their toilets, they had either accidentally or purposefully caused the facility's wastewater to back up. Often the goal was to gain extra time out of cell. By flooding their cell or cell block, they had forced the facility to move them during the cleanup period. And these misdeeds often had been rewarding - that is, until recently.
