The City of Houston's Northeast Water Purification Plant (NEWPP) is a conventional
surface treatment plant consisting of coagulation, flocculation, sedimentation, and
filtration processes. Primary and secondary disinfection is achieved with chloramines.
The plant has the capabilities for UV disinfection. The plant's rated capacity is 80
million gallons per day (MGD) and it serves the North Harris County and
Intercontinental Airport areas. The source water to the plant is Lake Houston water which
is a low alkalinity (40-60 milligrams/liter (mg/L)), low turbidity and moderate organic
content water. This plant was brought in to service in August 2005. This paper discusses how the City addressed a significant increase in caustic soda costs by developing an emergency
response plan to use lime slurry instead of caustic soda, and optimizing enhanced
coagulation to reduce the dependence on caustic soda that also eliminated the need for CO<sub>2</sub>. Includes tables, figures.
