Northeast Water Treatment Plant

Construction of Northeast Water Purification Plant in High Gear

During a flyover of the City of Houston’s Northeast Water Purification Plant Expansion project on 9/11/2020, I counted 13 construction cranes operating simultaneously on different parts of the site. The site stretches a full two miles from the start of the plant near the northeast corner of Beltway 8 to the tip of the water intake platform in Lake Houston. Here are photos that show the scope of this massive construction project.

The water intake platform stretches approximately 1100 feet out into Lake Houston.
The 108-inch intake pipes are larger than some pieces of construction equipment.
Looking NE toward Lake Houston along the path that the intake pipes will take through Summerwood.
Looking west toward the main treatment plant, with Beltway 8 in the background. Construction began in 2018.
Looking SW across the eastern portion of the new plant.
Looking SW across the western portion. The site is divided into about 10 sections each as large or larger than a city block.
A close up of construction activity in just one of the sections.
Looking straight east back toward Lake Houston from the western edge of the plant. Note the current water treatment plant in the foreground. It produces about 80 million gallons per day of fresh water.
Looking north over the center of the site.
Looking WNW. Note the NE corner of Beltway 8 in the top left. The plant expansion will provide another 320 million gallons per day.
For scale, note the size of the man on the scissor-lift in the red circle.

The plant expansion will supply 320 million gallons per day of treated water capacity in addition to the current 80 million gallons per day. So capacity will quintuple by completion in 2024.

Converting Area to Surface Water to Reduce Subsidence

The expansion of capacity will allow more water systems in the region to convert from groundwater to surface water. That should reduce subsidence and help avoid flooding.

Improved Techniques

According to the City, “The expansion will include conventional treatment processes like the existing plant that help coagulate, settle, filter, and then disinfect water.” Quality will exceed requirements set forth by the Texas Commission on Environmental Quality.

In addition, says the City, an advanced oxidation process called ozonation will disinfect water to help ensure that harmful organisms such as Giardia and Cryptosporidium are eliminated. Ozonation also helps eliminate taste and odor causing compounds, which improves the aesthetic quality of the water supplied by the plant.
