Accurate Flow Monitoring Aids Billing Process   Water & Wastes Digest April 2004   WWD Staff
When a new regional wastewater treatment facility opened in north Kern County, Calif., the nearby city of Shafter closed its own facility and began piping its residential wastewater to the new plant. Shafter, located 17 miles northwest of Bakersfield, Calif., has 12,000 residents. For billing purposes, the city needed to precisely monitor daily flow to the plant. The operators needed to remotely monitor flow between the city’s collection system and the regional treatment facility.

The Power to Separate   Water & Wastes Digest March 2004   By Austin Meyermann

In A Pinch   Water & Wastes Digest February 2004   David Lavender
Today, there is legislation to eliminate combined sewer overflows. Heavy fines are levied by the EPA against communities that violate this law. The EPA has been reasonable with enforcement because the costs are great--not to mention that it will take time to expand the infrastructure. However, as municipalities and utilities have learned, eliminating overflow events is a must.

Flow Monitoring Springboards City to System-wide Sewer Management Solution   Water & Wastes Digest April 2003
