P
Sanitary Sewer Service
Sanitary sewer service in Mecklenburg County is provided to private domestic homes
through four major means;
Public gravity service
2. Private on site disposal (septic tanks), and
3. Public low-pressure sanitary sewer.
4. Public or private pump stations
Public gravity service uses the natural flow of the terrain to remove wastewater from each
residence and deliver it to a suitable treatment facility for discharge back into the
environment. The use of this system is dependent upon two factors; I, A public utility to
transfer and treat the wastewater and 2. A geographic area (terrain) that will support the
use of gravity to convey wastewater.
On -site disposal of wastewater through the use of septic systems is used in areas that do
not have public gravity sewer service in place. This system is prevalent in the outlying
areas of the County as well as older subdivisions along the Catawba River.
Mthough the eastern shores of the Catawba River (Lake Norman, Mountain Island Lake,
and Lake Wylie) are within the Charlotte Mecklenburg Utilities service area, the terrain
•does not allow for the use of gravity sewer to serve the lakefront and Iake view lois.
Many of these lots slope towards the lake, directly away from the gavity sewer
infrastructure already in place.
Conventional pump stations are not practical along much of the lake font property due to
the massive destruction of trees and enviromnental concerns.
To serve these lake areas low pressure sanitary sewer systems are installed. This allows
for the residential wastewater to be conveyed to Charlotte Mecklenburg Utilities, utilizing
existing road rights -of -way. Your property is located .within the limits of a low-pressure
sanitary sewer system.
Why Is Low Pressure Sanitary Sewer Being Recommended For Certain Homes?
Property near steep and uneven topography (usually near lakes and creeks) can be
serviced efficiently with low-pressure sewer systems. The installation of conventional
gravity sewers would require substantially deeper sewer trenches and excavation with
substantially increased cost and a much longer period of construction. Even with these
deeper more expensive installations, the terrain will not allow a purely gravity fed
wastewater collection system. Properties with this special need also have special
maintenance needs as well. The following information will provide basic information
about low-pressure sanitary sewer systems.

I. GRINDER PUMPS
A grinder pump is installed on the customer's property in a buried %vet well, in those
areas being served by a low-pressure sanitary sewer system, Homeowners are required to
provide electrical power to the grinder pump.
A, Operation and Maintenance Issues
1. How does the grinder pump work?
The wastewater front your house flows by gravity through your waste plumbing to the
wet well. Once the liquid reaches a certain level within the wet well, the grinder pump
automatically turns on, grinds the wastewater, and pumps it (under pressure) out of the
wet well through the sewer main located along the street. The final discharge point can
be as far as a mile or more depending on terrain and existing gravity sewer service. Your
grinder pump has to have the capability to convey wastewater this distance.
2. Who Is Responsible For Grinder Pump Maintenance?
Any grinder pump maintenance and repair is the responsibility of the homeowner. The
homeowner should check with the company that installed the pump for an emergency
contact number and maintenance checklist. Each grinder pump should contain an alarm
system that will indicate to the homeowner a failure condition. The service box in the
road right-of-way is Charlotte Mecklenburg Utilities' responsibility,
3. Who to Call if There is a Problem:
Check Troubleshooting information in operation manual
Contact the plumber that installed your system:
(]']rase pul number here for future need) If you suspect a problem with the main line in the street, contact Charlotte-Mecklenabnrg
Utilities (Please state that you have a tow -pressure sewer system and the street address
where the problem is occurring): 704-357-6064. This number is answered 24-hours a
day, every day of the year.
4. What Type Of Maintenance Is Involved?
The grinder pumps normally specified are designed to have minimal Maintenance. For
example, in other coovnunities that have had low-pressure sewer systems for a Iong time,
the life expectancy of the pump ranges from six (6) years to fifteen (15) years. The life
expectancy is based upon wear and tear caused by the flushing of solids and petroleum -
based products, as well as operating against large grade differences.
Annual preventive maintenance is helpful to reduce potential service problems. Tliis
would include removing cover, operate pump manually, check for grease, exercise
shutoff valve and check alarm system. A small percentage of }homes (approximately 5%)
will require more frequent preventative maintenance due to family living habits, such as
heavy use of cooking grease. In these cases,, the pinup vault should be checked every 3
or 6 months, Heavy grease build-up i1n the wet well can be broken down with a spray of
water from the garden hose.
Yarbrough -Williams & Houle, Inc. — P.O. Box 1198— Pineville, NC 28134 — [phone]
4

Discharging unwanted items into the drain system, such as towels, panty hose and
clothing articles can cause blockages. It is better to keep such articles out of either
conventional gravity sewers or pressure sowers whenever possible. •
Do not plant trees ou top of the green sewer box. The tree will destroy your system and
cost a lot of money to repair.
S. How Much Does It Cost The Homeowner To Run The Grinder Pump On A
Yearly Basis?
(Ask the plumber/ company that installs the system for more information.)
6: Will I Lose Service During A Power Outage?
Yes. In a power outage, the grinder pump will not operate. In a power outage situation,
however, your water usage is normally Cut back. You will not be able to run your
dishwasher or clothes washer, and your hot water for showers will not last long. The
permit for the grinder station will provide additional information.
7. Is The Grinder Pump Noisy?
The grinder pump unit is buried within the ground and cannot normally be heard, even if
standing next to the unit,
S. Does The Grinder Pump Create Odors?
No, the grinder pump unit is designed to turd on with a frequency that does not allow the
wastewater within the wet well to go septic and give off odors.
Odors can occur as some gas escapes from the ►rents. The air vent (on your roof and / or
on the cover of the pump basin) allows the air and gas to escape as the wastewater flows
through. The gas then drifts down and may be noticeable to the homeowner, If odors gel
worse, document the tunes and whether the -system is being used (i.e. washer, shower;
etc. has recently been used). You will probably notice that these odors are created when
the system is in use,
9. What Will Prevent Wastewater From Entering My Pump From The Sewer Line
In The Street?
There are two (2) check valves on all low-pressure sewer systems to prevent the
wastewater from the sewer main from backing up to your pump. One (I) check valve is
installed in the pump discharge line between the pump and the street sewer.
Another check valve is installed in the service box located at the edge of the Street Right -
of -Way.
10. Is There A Warranty Period?
Check with the company that installed the purnp and the manufacture of the pump for
more information.
B. Installation Issues
Yarbrough -Williams & Houle, Inc. — P.O- Box 1198— Pineville, NC 28134 — [phone] 5

1. Where Is The Grinder Pump Installed? The grinder pump tiuit is usually installed
as close to the house as possible. The grinder pump is installed in a small, sealed,
underground plastic tank (wet well).
2. How Far Should The Grinder rump Be From My Well? The distance should be
50 feet, but can be as little as 25 feet in certain circumstances, For specific
information, contact Mecklenburg Health Department at 704-336-5100.
3. Can The Grinder Pump Unit Be Installed Within M'y CIosed Septic Tank?
Check with Mecklenburg Building Standards (704-336-4189 or 704-336-4180) before
deciding to install grinder pump in a septic tank. Generally speaking, most septic
tanks will not provide sufficient depth to allow the grinder pump chamber and pump
unit to be installed within the decoinmli85i0ned septic tank.
4. Are Modifications. Required To My Electric Service? Tile elect -deal circuit should
be capable of handling the power needs of the grinder ptunp equipment. Ask the
plumber / company that installs the system for more information.
Yarbrough -Williams & Houle, Inc. — P.O. Box 1198— Pineville, NC 28134 — [phone] 6

2. Maintenance Checklist
Bi-Annual preventive maintenance
