Water Treatment Plant Update: Resolving Hydropneumatic Tank Issues in Bridgeland

Bridgeland Resident,

During the evening of Tuesday, November 14, 2023, Inframark responded to an alert at Water Treatment Plant No. 1 (WTP1) of Harris County Municipal District No. 418 (HCMUD418). The technician found a faulty level probe on Hydropnuematic tank No. 1 (HPT1). Hydropneumatic tanks are filled with 50% water and 50% air to act as a “shock absorber” and regulate system pressure. The level probe monitors the amount of water and air inside the tank, and the tank will fill with air or water depending on the volume.

The level probe for HPT1 is scheduled to be replaced today (November, 15, 2023). To resolve the issue yesterday, the plant operations were switched from HPT1 to HPT2. When demand was placed on HPT2, the tank became “waterlogged”. This occurs when the water-to-air ratio is not at the recommended split. The tank fills with water, which depletes the air blanket needed to absorb the shock of pressure and consequently creates a pressure spike.

Both aforementioned issues with the HPTs will be corrected today. In the meantime, the plant is being operated manually to control pressure levels. We appreciate your patience.

Should you have any questions or concerns, please contact Mackenzie Osborne directly via email at Mackenzie.osborne@inframark.com.

Thank you,

Update: Stage 1 Drought Restrictions Lifted for Bridgeland Community Following Successful Water Conservation Efforts

Stage 2 of the Drought Contingency Plan (“DCP”) for the Bridgeland community was rescinded on October 10, 2023, with Stage 1 continuing in effect. The target for Stage 1 was a 10% water usage reduction. We are happy to report that the target for Stage 1 has been achieved for 7 straight days.

Hurricane Preparedness

Dear Bridgeland MUD Residents:

Please be advised, Texas Hurricane Season for 2023 will begin on June 1. We encourage residents to plan ahead to be safe in an emergency. Prepare now for the risks associated with storm weather and be ready to act when alerted by emergency officials.

Here are a few tips to help you prepare in the event of a hurricane:

  • Have an emergency plan and review with household members,
  • Stock up on supplies (water, batteries, first aid, nonperishables, etc.),
  • Bring items that can be easily picked up by wind indoors,
  • Close windows, doors, and hurricane shutters,
  • Fill vehicles and any additional cans with gas,
  • Pay attention to emergency broadcasts,
  • Have a plan for animals and plants; and
  • Move your vehicle to driveway or high ground.

In the event of an emergency, the best way to receive MUD related communications is through notifications distributed via HOA email & text alerts or visit your MUD website (www.bridgelanddistricts.org).

Bridgeland Water Conversion

Dear MUD Residents:

As you may be aware, North Bridgeland Lake Parkway is undergoing construction to expand towards Highway 99. As the road develops to reach the highway, the main water lines must follow. The main water line expansion will also provide water to your neighboring District, Harris County MUD No. 490. In order to do so properly, the disinfectant Harris County MUD No. 418 uses in the distribution system will be converted in sections of Harris County MUD No. 419 and Harris County MUD No. 489. During this period, you may experience taste and odor changes associated with this type of disinfectant conversion.

Public water systems are required to properly disinfect their water and maintain an adequate disinfectant residual in the distribution system. Chloramine (Free Chlorine combined with Ammonia) and Free Chlorine are widely used as disinfectants because they persist for long periods, while also limiting the formation of disinfection by-product contaminants.

Please find details with dates and sections affected below. On Monday, February 13, 2023, the following Harris County MUD No. 419 sections will be converted from Chloramines to Free Chlorine:

  • Moonlit Haven
  • Brook Haven
  • Arbor Haven
  • Meadow Haven
  • Lake Haven
  • Pine Haven

On Tuesday, February 14, 2023, the following Harris County MUD No. 489 will be converted from Free Chlorine to Chloramines:

  • Seminole Canyon

*Note: Harris County MUD No. 489 Seminole Canyon customers please be advised, the change to chloramines can cause problems to persons dependent on dialysis machines. A condition known as hemolytic anemia can occur if the disinfectant is not completely removed from the water that is used for the dialysate. Consequently, the pretreatment scheme used for the dialysis units must include some means, such as a charcoal filter, for removing the chloramine prior to this date. Medical facilities should also determine if additional precautions are required for other medical equipment.

In addition, chloraminated water may be toxic to fish. If you have a fish tank, please make sure that the chemicals or filters that you are using are designed for use in water that has been treated with chloramines. You may also need to change the type of filter that you use for the fish tank.

Please see attached map outlined in green and blue.

Please reach out to Inframark’s Customer Service at (281) 579-4500, should you have any questions or concerns.

Bridgeland Residents:
Please be advised, there is currently an outage effecting areas of HCMUD 419 and HCMUD489. During repair of an interconnecting valve, the pipe shifted once the line was exposed and created a 100 gallon per minute leak. In response, the surrounding lines must be isolated in order for crews to properly perform the emergency repair.

The current areas effected include:
The Reserves at Hidden Creek
Hidden Creek Estates
Bedias Creek
Cibolo Creek
Plum Creek
Barton Creek
Cedar Creek
Enchanted Rock

Unfortunately, at this time there is not estimated time of completion for repairs. The crew will be working throughout the night to restore services. We will communicate updates via the MUD 419 and 489 websites every two hours until service is restored.

For questions or concerns, please contact Inframark’s Customer Service team at (281) 579-4500 or visit your MUD websites at hcmud419.com or hcmud489.com.

Water Supply Restored

Water Supply from the WHCRWA has been restored. Our water conservation efforts helped the area’s surface water system recover quickly and we appreciate everyone’s support.

The community is operating at normal capacity. You can return to normal water use.

Bridgeland Water System Update

Residents living within the BLUE highlighted area on the attached map are being served by the Bridgeland North water distribution system which blends potable water from groundwater wells (on site) and surface water received from the West Harris County Regional Water Authority (WHCRWA). WHCRWA is the entity that sells Bridgeland surface water. The WHCRWA purchases its water from the City of Houston (CoH). Currently, CoH is experiencing a city-wide record high demand for potable water due to the extreme weather conditions. The City has requested its own retail customers and contract water customers (i.e.,WHCRWA) to voluntarily converse potable water usage to satisfy the high demand. Due to the cooperation of the residents in WHCRWA and the CoH, the system was able to maintain acceptable pressure last night and stay within drinking water guidelines as required to prevent a Boil Water Notice (BWN). Today the tanks are slowly refilling and if we, as a community, can continue to work together and maintain a conservative usage pattern, we can bring the system back up to full capacity.

We understand that some homes have been affected by water leaks and pipes because of the freeze, which also impacts the overall system’s water pressure. Inframark has dispatched numerous crews around the clock over the last several days (and continues to do so) to support residents who have been affected by frozen or broken pipes as it is our priority to support the community and maintain adequate water pressure. Please contact Inframark 24/7 at 281-398-8211 if you see any leaking water regardless of where it is, or your neighbor have been impacted by the freeze and need help shutting your water off or evaluating an issue.

We will continue to monitor the system and provide our next update this evening or earlier if conditions change. Please share this email with your neighbors and encourage them to visit their specific MUD website for more information.

We thank you for your assistance in keeping our potable water supply safe and viable.
