The City of Houston’s new $2 billion Northeast Water Purification Plant between Lake Houston and Beltway 8 East is now more than 50% complete. The last monthly progress report posted on GreaterHoustonWater.com was from more than a year ago. At the time, it showed construction 55% complete. Since then, the City has continued to post detailed periodic construction updates. The latest was in March 2022. It featured 79 pages of photos that dramatize the complexity of such a huge project. A flyover of the plant on 7/22/22 showed even more progress.
The latest timetable shows completion of the first phase early next year and completion of the second in 2025.
The Harris-Galveston Subsidence District says that land subsidence is caused by the withdrawal of groundwater. For that reason, regulations have been put in place to limit the use of groundwater.
By 2025, surface water must supply at least 60 percent of our water. The plant should meet that objective. And, it will wean 80% of the region off groundwater by 2035.
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.
The two pipelines leading to the Northeast Water Purification Plant are each 9 feet tall!

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 Texas Commission on Environmental Quality requirements.
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 Northeast Water Purification Plant.

The hand of sand miners weighs heavily on the San Jacinto watershed. Not all miners. But many.
While exploring the river basin by helicopter last week, the contrast between two scenes struck me: 1) The natural blanket of green in Lake Houston Wilderness Park. 2) Sand mines that lined the banks of the East and West Forks for miles.
The trees and natural wetlands inhibit floods. They slow floodwaters down, hold them back during heavy rains, and reduce erosion. The sand mines do not. They may provide some floodwater detention, but the pits are often filled to the brim and their dikes often break.
How you treat the land determines how it treats you. Especially during floods. This aerial photo essay shows how the San Jacinto River Basin used to look and how it looks today.
Lake Houston Wilderness Park
Peach and Caney Creeks border Lake Houston Wilderness Park on the west. The San Jacinto East Fork borders it on the east. The shot below represents the way the whole Lake Houston area used to be.
Looking across the 5000 acres of Lake Houston Wilderness Park – the largest urban nature park in America.
Compare That With These Shots
This first provides a direct comparison.

I’ll provide five more shots here, all from the West Fork San Jacinto. They represent more than 500 similar shots I took on 7/22/22.
No Swimming
When I see all this environmental degradation, my mind starts swimming – despite the scary water.
How much sediment gets swept downstream in floods?
Can this land ever return to productive use?
Do other cities allow mining in urban environments upstream from their water sources?
What effect does mining have on the water quality in Lake Houston?
What percentage of our water bills goes to cleaning up this water?
Why doesn’t Texas have performance bonds that ensure sand miners leave the land in habitable shape?
The sand makes concrete. It supports growth. But is all growth good?
Is growth in one area at the expense of public safety in another worthwhile?
Should we limit the concentration of mines in an area?
Why do mines expect the public to pay their cleanup and reclamation costs?
Is it safe to build mines below a dam that releases enough water during floods to break the mines’ dikes?
Are there no alternatives?
Cycle Continues
New Segment H of the Grand Parkway cutting east through forests will attract more subdivisions that require more sand for more concrete.
I encourage rebuttals from any mine owner who wishes to address these questions.

The Colony Ridge development in Liberty County, aka the world’s largest trailer park, has more than doubled in size in the last 3 years. Measurements in Google Earth show that Colony Ridge, which started clearing land in 2012, has expanded from approximately 8,000 acres in 2019 to almost 20,000 acres today. To put that in perspective, Kingwood comprises approximately 14,000 acres and took more than 40 years to build out.
Colony Ridge started developing on the left (west). It is expanding eastand north.
Growing Pains
But the rapid growth of Colony Ridge has not come without pain:
Rivers of mud continue to flow out of drainage ditches with big rains because the developer flaunted construction regulations for them.
Consequences of Poor Construction Practices
As a result of such drainage issues and exposed soils, more sediment flows downstream than otherwise would. This contributed to sediment buildups on the San Jacinto East Fork (see below). Those, in turn, reduce conveyance and contribute to downstream flooding – unless the public continues to spend millions on dredging.
East Fork Mouth Bar after Imelda but before recent dredging. Average river depth had been reduced to three feet.
Still Not Following Best Practices
Aerial photos taken on 7/22/2022 with Ken Williams and Bill Callegari, two fellow members of the Harris County Community Flood Resilience Task Force, show the current state of the development and construction practices in Colony Ridge. Sadly, not much has improved. For instance, the developer still piles dirt on the edge of ditches without protecting them with silt fences.
Note long drainage ditch cutting diagonally through middle of frame. Developer has piled dirt next to it (middle left of frame) without protecting ditch with silt fencing.Major ditch cutting through older section is sill not protected with back-slope interceptor swales or vegetation.Erosion is rampant.
Water shooting down the ditch above created a major headache during Harvey. See below.
FM 1010 Still Washed Out
Floodwater from the ditch washed out FM 1010. This major N/S thoroughfare still needs repair…five years later!
Break in FM 1010, aka Plum Grove Roadforces residents to detour for miles.
Photos Showing New Development
Area developed last year is starting to fill in with new trailer homes already.Note absence of fire hydrants…still.Looking east at area still under construction.Looking E from NE corner of development.Another area semi-cleared but still unpaved.
If there’s good news in these photos, it is that the developer appears to be leaving more natural ground cover in the newest areas. Still, without vegetation on the sides of ditches, without better construction practices, excess sediment could continue washing into the Lake Houston Area for years to come.
Downstream residents will continue to pay the price for egregious development practices upstream.
Someday, the people who buy these lots will also become flood victims of similar new developments even farther upstream.
Will we continue to repeat mistakes of the past in ever widening circles? Will we continue to sow the seeds of future flooding? Or will we wake up to the fact that we are all part of one giant community?

Project Benefits
The plant will provide enough treated surface water to reduce subsidence, which causes much of our flooding problems according to the City of Houston and the Harris-Galveston Subsidence District.
The Harris-Galveston Subsidence District says that land subsidence is caused by the withdrawal of groundwater. For that reason, regulations have been put in place to limit the use of groundwater.
By 2025, surface water must supply at least 60 percent of our water. The plant should meet that objective. And, it will wean 80% of the region off groundwater by 2035.
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.
Then and Now Pictures Show Progress
The last time I posted about this project, construction was kicking into high gear back in September of 2020. Below are five pairs of photos from then and now that show how far it has come.

Below, note the difference in water levels between the creek and mine. No doubt, you also noticed a difference in water color. That bright blue/green in the mine water likely comes from high chloride levels.

These images support the need to harmonize and enforce higher drainage standards throughout the region. Without change two things will happen:
