RE: Chlorine Contact Chamber Replacement
Bnarwood Subdivision WWTP
NPDES Permit#: NCO029882
Dear Mr. Berry,
Please find enclosed a Authorization to Construct request for the Briarwood Subdivision WWTP. The plant is
privately owned, serves a small subdivision, and is located in Buncombe County. This project is for the
replacement of the existing chlorine contact chamber at the WWTP and would be considered a facility
modification. The timeline for this project is to install the tank as soon as possible. The operator for the WWTP
is Ms. Juanita James.
Currently, there are 15 single family homes connected to the WWTP and there are no plans to expand or add
any additional homes to the WWTP.
WWTP Components
The WWTP at Windy Gap consists of the following elements
1. Manual Bar Screen
2. Reactor Basin
3. Clarifier
4. Chlorine Contact Chamber
5. Dechlonnation Manhole
6. Associated piping and blowers for aeration
Existing Chlorine Contact Chamber
The existing chlorine contact chamber is original to the plan and is no longer structurally sound. The walls and
baffles of the chamber were constructed with masonry block and thejoints are cracking. The exterior walls are
no longer plumb and are bowing inwards on the structure.
Chlorine Contact Chamber Replacement
The proposed 356 GAL chlorine contact chamber will provide adequate a minimum of 15 minutes of contact
time at the maximum peak flow for the WWTP. A local concrete precast company will be use to cast the
chamber and baffle walls. The proposed chamber will connect to the existing influent and effluent lines at the
WWTP.

Chlorine Contact Chamber Replacement
11292017
Construction Sequence
The construction sequence is as follows
1 Block flow from entering existing chlorine contact chamber
2 Pump and dispose of wastewater in existing chlorine contact chamber
3 Pump and dispose of wastewater in existing clarifier
4 Demolish old chlorine contact chamber
5 Install new chlorine contact chamber
6 Test and place new chlorine contact chamber
7 Return flow to normal operation
Mr David Burnette is the owner of the WWT:l and is also a licensed utility contractor He will be performing the
work described above, except the hauling and pumping with will require a licensed septic hauler A 3,500
gallon septic tank pumping truck will be used and based on his experience, the plant will not discharge for
roughly 48 hours
Engineering Calculations
Attached to this letter are the calculations for the chlorine contact time, the buoyancy calculations, and the
bearing capacity of the new tank
Soil borings were not completed for this project and therefore the depth of the watertable is not known Based
on my own observations, I do not anticipate the water table being less than 3' deep
No additional permits are needed to complete this work The disturbance is less than 1 acre and therefore an
Erosion Control Permit is not required by the ordinance in Buncombe County
Attachments for Review
The following items are attached for review
• Application for Authorization to Construct Permit (Form ATC -12-14)
c NPDES Permit
• Engineering Plans
• Engineering Calculations (Two pages attached to this cover letter)
• Technical Specifications
• 1 CD with a digital copy of all of the above items
