About Our Wastewater System




Protecting and enhancing our State’s water resources,
the NTMWD provides wastewater treatment services

to cities and communities within the service area. The
NTMWD regional wastewater treatment plants are
designed, constructed, and operated using wastewater
technologies to protect the health of our communities,
preserve our precious water resources, and enhance
the quality of the water environment.

The wastewater treatment process removes
contaminants and other harmful organisms from the
wastewater, so that once cleansed at the treatment
plants, it can safely be released back into a receiving
waterway. Typically, wastewater treatment plants treat
only residential wastewater; however, the NTMWD
wastewater treatment plants also provide industrial
pretreatment programs for wastewater flows received
from non-residential entities. Pretreatment programs
establish responsibilities and standards for
non-residential entities to control pollutants that may
pass through or interfere with the treatment processes.
Since treated wastewater effluent is eventually used
again to supply drinking water, irrigate crops, and
sustain aquatic life, all processes and programs
implemented within the NTMWD Regional Wastewater
System are designed to have the least amount of
environmental impact to receiving waterways, while
maintaining standards established by Federal and
State regulations.

NTMWD owns and operates four regional treatment
facilities that provide secondary and/or tertiary level
wastewater treatment services. In addition to the
regional facilities, NTMWD operates an additional 14
smaller treatment plants that are included in NTMWD's
Sewer System.

 

NTMWD's Regional Wastewater System and Sewer
System treated over 32 billion gallons of wastewater
during the 2011-2012 Operations Year (October 2011 - September 2012). Of the total wastewater treated, 80% received treatment at one of the four regional wastewater treatment plants, while the remaining 20% received treatment through NTMWD's Sewer System.

 

Construction contracts within the Wastewater System totaled over $124 million. The largest expenditures included South Mesquite Regional Wastewater Treatment Plant (RWWTP) Expansion to 33 MGD; the Wilson Creek RWWTP Expansion and Advanced Treatment Improvements; and the Panther Creek RWWTP Expansion. Additional projects at wastewater plants included improvements to the Floyd Branch RWWTP Ultraviolet Disinfection Facilities; the Wilson Creek Lift Station improvements; and the Rowlett Creek RWWTP improvements.

 

Additional expansions, improvements, or rehabilitations to several force mains and lift stations included: the North McKinney Lift Station; the Rowlett Cottonwood Reinforced Concrete Pipe Transfer Sewer Rehabilitation; the McKinney East Side Extension Parallel Interceptor; the McKinney Lift Station Rehabilitation; the Upper Cottonwood Creek Emergency Generator; the Forney Force Main Replacement Line; the Gravity Interceptor Improvements; and the Indian Creek Lift Station Improvements.
