You might have received communication from your local municipalities notifying you of a new ordinance requiring you to abandon your septic tank system and to tie into the City sewer system. This means that your septic system will no longer be necessary and once the sewer tie in is complete, your sewage will flow out to the city sewer. The occurrence is becoming more common in Fresno and Madera Counties as city lines are expanding into what were once rural areas.
Sewer Tie In involves connecting the sewage line from the home to the sewage line for the city. A sewer mainline will need to be installed connecting the home to the city sewer line. Many times, this may be done in conjunction with a septic line abandonment as city services expand to what were once rural areas. Depending on your area, a permit may be required for this process.
Because of the complexity and the use of public services, there are many codes and regulations specific to each municipality that must be followed to complete this process. For the sewage to flow correctly, the pipe must be graded properly. This allows gravity to feed the sewage to the city line. If there is not proper grading, or too many turns in the line, it may require the use of a pump. A sewer tie in is best completed by a licensed plumbing company, and this may be a requirement of your municipality.
Because of the codes and regulations, as well as the expertise and equipment necessary to access the city sewer lines under the street, a proper sewer tie-in can be quite costly. Estimates range from $5,000-12,000. Thankfully, many municipalities offer rebates, grants and other programs to help offset the cost. Contact your local municipality to find out what programs may be offered.
In most cases the city will extend their sewer piping system, furnishing the capability for property owners to tie into the sewer line. It is the homeowner's responsibility to furnish the labor and materials on their property to tie into the sewer line. You will also need to pay connection fees. As these are extensive projects, unfortunately they tend to be costly.
If you are wondering why hooking up to the city sewer line is such a large investment, the factors that make the project so costly and extensive include:
There is a wide array of reasons that cities are expanding their sewer lines to properties that are serviced by septic systems. City boundaries are growing around Fresno and Madera counties, and as agricultural land is getting developed a lot of these properties are getting annexed into the city. This means what was once zoned as a county property is now rightfully part of the city dividing line. As building departments require these new developments to tie into the city sewer, the existing properties around these new developments will need to tie in as well.
It is becoming more common for larger homes to be built on smaller lots. These smaller lots do not have the capacity to cope with a septic system as there is not enough space to install one. Some existing septic systems do not have the space to install a new one as current one ages out and eventually fails. If a property owner does not have the space to install a new septic system, there needs to be a resolution. The resolution is for the city to expand its sewer lines creating the ability for the property owner to do a sewer tie in and have functioning plumbing.
Also, often times environmental contamination can occur as septic systems are put under pressure and no longer effective. This poses public and environmental health hazards. This may contribute to the need to tie in to the local city sewer line.
There are definitely positive and negative aspects to joining your local city sewer line. Some of the benefits include:
Of course, you will run into a few drawbacks now that you are part of the sewer system. Cons to consider are:
Sometimes, the sewer pipes belonging to the homeowner may require repair. Here are some common problems, prevention and solutions:
This can be caused when a heavy object impacts the pipes below, causing them to become crushed. This may also be caused by roots from trees and shrub, which can be quite strong and may infiltrate your sewer pipes. If this happens, it may cause sewage to seep in to your land. Depending on the situation, options for repair include water jet, simple spot repair, or a total sewer replacement. Sewer line cameras can help to diagnose the cause. As a preventive measure, make sure to consider placement of trees and shrubs whose roots may damage your sewer line.
Fats, oils and grease go down the drain as a liquid, but as they travel through the home's sewer system, they begin to harden. Over time, enough grease can accumulate to create a stoppage. When this happens, typically a powerful water jet will clear the issue. To avoid this problem, dispose of fats, oils and grease in to the trash instead of the drain. If you have recurring stoppages, it may be due to a "back-pitched" pipe (too many turns) or faulty installation. See below for more information.
If your sewer line was installed with too many turns, this may interrupt the natural flow of gravity to the city line and create unnecessary blockages. In some cases, a spot repair may solve the problems. However, a complete relaying of the pipe may be necessary to achieve the proper grading and flow.
During the process of connecting to the sewer, your septic system will need to be abandoned. This can also be referred to as decommissioning your septic tank. Digging up and removing the septic system is costly and rarely done.
The piping will no longer be used will remain buried. A new sewer mainline will be installed to connect to the city sewer. When a septic tank is decommissioned, it is usually filled with sand or concrete and reburied.
