Sewage Cleanup >> How To Get Rid Of Sewage

Overhead Sewers. The basement floor drain and any plumbing fixtures in the lower levels of your house that have experienced backups will be disconnected from the sewer system. Plumbing from those fixtures will be re-routed to a sealed tank. Inside the tank,an ejector pump lifts the waste water up several feet high in new plumbing before How To Get Rid Of Sewage dumping into your sewer line. 

Often the new plumbing is connected "overhead" to pipes that lead out of your house and dump into the sewer line. Since the fixtures in the lower level are no longer directly connected to the sewer line, How To Get Rid Of Sewage they cannot experience a backup.Plumbing fixtures on upper floors of your home that have never experienced backups need not be routed through the ejector pump system. 

Advantages: a. The system does not rely on How To Get Rid Of Sewage proper closing of a backflow valve to prevent backup from the street sewer. b. Loss of power during a storm does not affect use of upper level plumbing fixtures. Disadvantages: a. Sewage ejector may fail to operate during a heavy rain and may be a problem.

b. Use of lower level plumbing fixtures should be curtailed during heavy storms.c. Check valve failure could allow backups to still occur.d. Sewage ejector pump will be inoperable during power failure. Sanitary Sewer Overflows (SSOs) Due to Inflow and Infiltration (I&I) Sanitary Sewer Overflows (SSOs) violate USEPA and IEPA Regulations, pollute the lake How To Get Rid Of Sewage and streams and expose the public to serious health risks. 

Most of the SSOs in Decatur are due to Inflow How To Get Rid Of Sewage and Infiltration (I&I) resulting from large storm events. An I&I program should be established reduce the number of SSOs. There are several areas in the separate sanitary sewer collection system were I&I causes surcharging of the sewer which causes basement backups and SSOs.  

The extraneous flow from I&I consumes capacity in the collection system and increase the volume of sewage that must be treated at the Sanitary District of Decatur. In response to the USEPA and IEPA, the Sanitary District is requesting the City to report all SSOs to the District. The Sanitary District has also requested the City investigate I&I problems to find and How To Get Rid Of Sewage implement corrections.

The I&I program should start in the shaded areas shown in figure 2. Selected areas should be further screened by flow monitoring How To Get Rid Of Sewage and the following existing and proposed programs as discussed here-in the Master Plan:1. TV Inspection Program 2. Smoke Testing Program 3. Illegal Sump Pump Removal Program

4. Asset Management Program 5. Manhole Inspection Program 6. Sanitary Sewer Backup Prevention Program (Overhead Sewer Program)The results of these site specific investigations will be used to formulate reduction plans for the study area and How To Get Rid Of Sewage provide the basis for a cost-effective analysis to be performed. 

The analysis will determine if I&I reduction measures are an economical alternative compared to increasing the system capacity in the study area. The cost to begin and I&I reduction program is initially $300,000 per year. After two or three years of preliminary studies and How To Get Rid Of Sewage engineering design, the approximate cost to begin physical improvement to reduce I&I is estimated to be $500,000 per year. 

The I&I program is expected to be and on-going work effort for the foreseeable future. System Operation and Maintenance The City should change the operation and maintenance program from reactive to proactive. Currently, How To Get Rid Of Sewage the City has an annual emergency sanitary sewer repair program to repair failed sewers and manholes thought the year. 

Repairing sewers after they have failed is costly anddisruptive to the public. The failures can also cause basement backups or sanitary seweroverflows (SSO's). With an asset management approach to identify, plan, and How To Get Rid Of Sewage rehabilitate the small diameter sewers, the number of the emergency sanitary sewer repairs should be reduced in the future.

Sanitary sewer cleaning is one of the most cost effective ways to prevent basement backups and sanitary sewer overflows. If roots, grease and debris is not cleaned from the sewers it will reduce the capacity of the pipe and cause backups and How To Get Rid Of Sewage SSO's. The following programs as described in the report are designed to maintain the system and provide maximum capacity in the system: 1. Contract Cleaning Program.

2. Herbicide Program.3. TV Inspection Program. (continued program) 4. Sanitary Sewer Emergency Repair Program. (continued program)The annual increased cost for system maintenance How To Get Rid Of Sewage and operation is initially $350,000 with an annual increase of 3% to match inflation rates. Increased maintenance will be necessary for the foreseeable future.

4. Small Diameter Sewers Small diameter sewers comprise 96% of the entire sanitary sewer collection system, roughly 2.2 million feet of sewers and 8,000 manholes. Repairs How To Get Rid Of Sewage and upgrades to the small diameter sewer system should be analyzed on an asset management basis. An asset management approach will give a calculated rating to the pipe or manhole based on condition, service area, depth, size, and location. 

This rating will provide the City with the criticality or consequence of failure for each pipe segment. The repairs to the pipes How To Get Rid Of Sewage and manholes will be prioritized by the highest rating. The rating can be calculated from the GIS mapping software and TV inspections that have been performed over the past ten years. 

The sewers and manholes will be repaired by lining, point repairing, open cut excavation, How To Get Rid Of Sewage or pipe bursting. The method of repair will depend on the type of defect and will be analyzed on a case by case basis. The total estimated cost of repairing the small diameter sewers is approximately $17 million dollars. The small diameter sewers should be rehabilitated though smaller annual projects rather than a large capital improvement project that is financed. 

The cost to rehabilitate the small diameter over a 20 year timeline is about $850,000 per year. This How To Get Rid Of Sewage project will continue to be needed after the 20 year timeline because sewers will need to be rehabilitated in the future as new defects in the pipes form.
