Installation and Maintenance

Manhole Install


A sewer manhole is a hole, either in the road or in an easement, that gives sewer employees an access point to clean, televise and otherwise inspect the sewer mainlines. These holes are covered with a manhole lid. Although the only part of the manhole that is visible is the lid, there are a number of other parts to the manhole. In the bottom of the manhole there is a connection to the sewer pipe. As part of Operations & Maintenance and Rehabilitation, we often install, replace, and repair manholes.




Mainline Open Cut

Mainline –

A sewer mainline is any sewer line that is owned and maintained by a public entity. Parker Sewer District has over 260 miles of sewer mainline we own and maintain throughout the District. We often need to replace or repair our mainlines for regular operations and maintenance purposes. Our Rehabilitation Project, which is much more comprehensive, will also upgrade and replace many of lines throughout the District.

We have two different types of mainline:

  1. Gravity fed – gravity fed line is the normal type of sewer line that takes all the wastewater downhill through a variety of pipes until it reaches the treatment plant.
  2. Force Main – force main sewer lines take wastewater that has been pumped via a pump station uphill to where it can pick up and flow together with other gravity fed sewer line.


ROW Clearing

Right-of-Way Clearing –

Right-of-Ways (ROW) are Easements that Parker Sewer District has where our lines go through private property. Although most of our lines lie underneath the road, in many cases they do not. We must maintain our lines even in these areas where they go through private property via the easement. Therefore, in areas where the brush and foliage is not cut back by the property owner, our crews must maintain and cut down the plant and tree growth. If this is done, we know we are able to get even our heavy equipment and large trucks down through the easement to make repairs, clean lines, or conduct inspections.




Pump Station

Pump Stations –

Pump Stations exist to take wastewater and pump it uphill to a point where it can join other gravity fed lines. A wet well gathers the wastewater, where at different times the pumps will turn on and send the wastewater out through the force main. Parker Sewer owns and maintains six of these pump stations.






Biological Grease Treatments –

Our employees drop biological grease treatment bags at various spots throughout the District. This treatment contains microscopic bacteria that eat away at grease deposits that accumulate in certain spots. Grease, if left untreated, can easily cause a sewer blockage.

Emergency Stoppage

Emergency Stoppages –

Our administrative offices are open M-F 8am-5pm. Our field crews work M-F 7:30am-4pm. However, after hours we have a sewer crew on-call at all times to respond to calls where there are sewer stoppages or overflows. If the stoppage is in the sewer mainline, our crews will break the stoppage. As we maintain our sewer lines this is part of our job and this is done at no direct cost to the person calling in the stoppage or any other constituent. However, in certain cases, our crews may determine that the sewer blockage is located in your service line. In these cases the sewer service line is owned and maintained by the property owner, and you should call a plumber. For a list of plumbers we can recommend, click here. If you are in need of service, please call us at (864) 467-4030.



Overflow Manhole

Overflows –

In some cases a stoppage in a sewer line can back up so far that sewage starts coming out of a manhole, clean out, or other location and gets out onto the ground. If you see this, please call us immediately at (864) 467-4030. Sewage on the ground is a public health hazard and can be very dangerous to anyone who is exposed to it. It can also pollute the local waters of the State if it enters a ditch or stream. Overflows may be caused by a stoppage or they may be caused when there are rainstorms. During rainstorms, large amounts of rain water get into the sewer lines and cause them to become over-capacitated with water. We call this I/I (pronounced I – and – I), which stands for Inflow and Infiltration. One of the main purposes of our Rehabilitation Project is to cut down on I/I.



GPS Work

GPS Work –

We are currently in the process of gathering a GPS (Global Positioning System) point for every manhole within Parker Sewer District. This will help us have accurate maps with all our manholes shown in the correct location. Our manhole GPS points will have sub-meter accuracy.
