Process instrumentation is an often overlooked, yet incredibly important component of wastewater treatment operations in small to medium size wastewater treatment facilities. Learn how the City of Hartford Water Pollution Control Facility (WPCF) implemented additional process instrumentation to enhance their operations.
Process instrumentation and overall solids management are two often overlooked, yet incredibly important components of wastewater treatment operations in small to medium size wastewater treatment facilities. Learn how effective process instrumentation and management of the downstream solids process can greatly improve your facility operations.
The Village of Hartland’s Arlene Drive sanitary lift station serves a high-end residential community adjacent to a golf course. Many of the homes served by this submersible lift station use a cleaning service. Unfortunately, “disposable” wipes and other cleaning materials that are frequently used by these cleaning services are often flushed down the toilet, clogging the lift station pumps. Before this issue was resolved, the Village utility staff were sent out several times a week to pull the pumps from the wet well and unclog them.
The City of Franklin had one subdivision that was experiencing unusually high peak to average sewer flows. A hundred homes were 1950’s vintage, the subdivision was rural cross section with ditches, and there were known homes with hung plumbing and possible cross connections. Learn how utility rehabilitation assisted in resolving this issue.
Do you have an area in your system where breaks are common, back-ups are anticipated, or bypassing occurs frequently? Effective management and planning by public works staff are critical to meet the demands of deteriorating infrastructure and go from being “reactive” to “proactive” with maintaining your underground facilities.
The City of Peshtigo has experienced recent sewer system overflow events that have been partly due to high wet weather flows. R/M assisted in performing a smoke testing program as part of the City’s sewer system evaluation survey (SSES).
Some of the primary goals of CMOM programs are to protect public health, avoid basement backups, prevent sanitary sewer overflows, and protect the infrastructure investment. Municipalities place high emphasis on investigating private laterals in addition to the public sewers when they experience higher flows at their wastewater management facilities, sewers surcharge, or basements backup during wet weather events.
A TMDL affects municipalities in two main ways; through its wastewater treatment facility (WWTF) permit or through its Municipal Separate Storm Sewer System (MS4) permit.
Learn more about several innovative approaches municipalities can take in working towards TMDL compliance.
Why do some streams have TMDLs while others don’t? When monitoring or sampling results over a designated period of time reveal problems with the physical, biological and/or chemical conditions of a stream, river or lake, a waterbody can be listed on a state’s Impaired Waters List.
