In the aftermath of recent flooding, the city of St. Louis has labored to protect vital infrastructure from the damages that the flooding has created. This includes wastewater treatment plants, highway bridges, embankments and more. St. Louis has collected necessary information on water flow data and level to be entered into the National Water Information System. This essential tool is specifically for monitoring heavy storms that can potentially cause damages, as well as to forecast floods and droughts in real time. Some communities in Missouri continue to battle rising floodwaters, while others are beginning their recovery efforts. As water levels begin to recede on some smaller rivers, residents are encouraged to use caution near flood water as contaminants can pose a health risk. It is estimated that nearly 200 homes have been impacted by the floods, with many more at risk of exposure to the flood-like conditions.

Interesting fact: did you know that residential waste stabilization lagoons are commonly used for onsite sewage treatment? The lagoons are used when the soils are unsuitable for the traditional gravity flow drain field systems.  A lagoon consists of an artificial pool for the treatment of sewage, or to accommodate surface water that overflows the storm drains during heavy rain. Interestingly, a septic tank is the most common onsite sewage treatment system for cities throughout Missouri. However, a connection to the city’s sewer system is the most reliable means of sewage disposal.

St. Louis, you’re invited!! Perma-Liner Industries requests your attendance at our Open House in Anaheim, CA. It’s taking place for three days from June 13th –June 15th and we want to see you there! It’ll be chock-full of live demonstrations and information on all of the CIPP technology available. Don’t miss this! Call us to confirm your reservation @ 1-866-336-2568

The Metropolitan Sewer District is implementing a long-term control plan (LTCP) to eliminate all sewer overflow disturbances during a 23-year period, as part of a consent agreement. The MSD is expediting project delivery throughout its service area by implementing a structured schedule and outlined design for several area infrastructure improvement projects.  The Lemay Watershed will undergo more than 70 projects during a 5 to 10 year period. The Lemay Service Area covers nearly 119 square miles in the City of St. Louis and a portion of St. Louis County west and south of the city. The program will encompass four watersheds within the Lemay Service Area, including Gravois Creek, Mackenzie Creek, Martigney Creek and University City. Some areas are served by combined sewers while others are served by separate sanitary and storm sewers. Wastewater treatment is provided at the Lemay Wastewater Treatment Facility.

The span of the project includes review and evaluation of sewer sizes, recommended alignments and lengths, including hydraulic analysis and design assumptions, as well as private inflow reduction (PIR), and preliminary studies for some projects. Wet weather storage facilities and pump stations will be constructed to handle peak flows during storm events. Storage facilities may be above or below ground and will be designed to blend in with the surrounding area. The storage facilities will be equipped with automatic controls for filling, emptying and flushing as well as remote operation.

St. Louis, SAVE THE DATE!  Perma-Liner Industries cordially invites you to the annual WWETT show! The Water & Wastewater Equipment, Treatment & Transport Show is happening on February 17th– 20th at the Indiana Convention Center.

St. Louis has sustained historic flooding from the Meramec River, a relatively small Mississippi tributary that bombarded communities in the far southwestern reaches of the St. Louis suburbs during the week. Two wastewater treatment plants were so damaged by the floodwaters that raw sewage spewed into the river. Hundreds of people were evacuated in the Missouri communities of Pacific, Eureka, Valley Park and Arnold, where many homes took in water. Two-dozen homes in Cape Girardeau also sustained damage from flooding conditions. Catastrophic damage has been a result in several nearby areas. Evacuations were required in the areas most threatened, as conditions were expected to persist, calling for a State of emergency.

In addition, road closures abounded. Traffic was rerouted to allow for sandbagging and pumping, including a 24 mile stretch of Interstate 44. The Mississippi River, which runs beside the Gateway Arch and downtown St. Louis, was also expected to reach nearly 13 feet above flood stage, which would be considered the second-worst flood on record, behind only the devastating 1993 flood.  Although a flood wall protects the city, firefighters and emergency road crews worked to pump out water from flooded storm drains behind a 7-foot-high, 1,000-foot-long temporary retaining wall reinforced by gravel and sandbags. Spring River, which was among the waterways to overflow, was also under advisement.

Currently, conditions call for a massive cleanup and the State of emergency has been lifted, interstates are also slowly returning to normal. The St. Louis region is now struggling with the most extensive flooding seen in more than 20 years.  Perma-liner Industries is here for you! Call us or go online so we can offer you our best products and services during the aftermath and cleanup period of this devastating flood. 1-866-336-2568/ www.perma-liner.com

Soils for Sewage in St. Louis

Soils for Sewage in St. Louis


Posted By on Nov 24, 2015

A septic tank is the most common onsite sewage treatment system in use in Missouri. Nearly 30 percent of all housing units in Missouri use onsite wastewater treatment systems.  For at-risk areas, connecting to an adequate public sewer system is generally the best alternative for disposing of domestic sewage from private residences. Where access to a public sewer system is impractical or too expensive, proper siting and design of an onsite sewage system is critical to avoid its premature failure. Misuse of individual sewage systems results not only in water quality problems and nuisance conditions, but also in costly repairs to rehabilitate a failing system. Failing systems include both those that you can see and smell and those that seep effluent, or waste liquids, into groundwater supplies before the soil can properly remove disease-causing pathogens.

A septic tank system consists of three major components: the septic tank, a distribution device and an absorption field. A septic tank is a large, watertight, corrosion-resistant, buried container that receives raw sewage from the plumbing drains of the home. In it, solids are separated out of the raw sewage and are partially digested by anaerobic (oxygen-lacking) bacteria.  After primary treatment in the septic tank, the liquid effluent flows through the distribution device, which ensures that equal quantities of effluent go to each pipe in the absorption field. The absorption field is a subsurface leaching area within the soil that receives the liquid effluent from the distribution device and distributes it over a specified area where it is allowed to seep into the soil. The filtering action of the soil, combined with further bacterial action, removes disease organisms and treats the harmful material in the effluent, completing the treatment process so that the water is recycled to the surface or groundwater source.
