Groundwater Reduction Plan (GRP) Fee to Increase October 1, 2025

Residents and businesses in Fort Bend Municipal Utility District No. 47 (FBMUD47) will see an increase in their Groundwater Reduction Plan (GRP) fee effective October 1, 2025. Missouri City’s current GRP fee of $1.99 per 1,000 gallons for groundwater users will increase to $2.39 per 1,000 gallons.

This adjustment is a necessary step in addressing land subsidence and ensuring a sustainable water supply for the growing region.

Understanding Your Water Source and the Need for a GRP

The water delivered to FBMUD47 residents and businesses comes from deep underground sources called aquifers, pumped via groundwater wells. While readily available, excessive groundwater withdrawal can lead to a significant environmental challenge: subsidence –the sinking or settling of the ground surface.The Fort Bend region, experiencing rapid population growth and increased development, has seen groundwater extraction outpace the natural replenishment of aquifers through rain and other sources. This imbalance can exacerbate flooding and lead to other adverse impacts.

The Fort Bend Subsidence District and its Mandates

To combat subsidence, the Texas Legislature created the Fort Bend Subsidence District (FBSD) in 1989. The FBSD’s primary mission is to regulate groundwater withdrawal, promote water conservation, and encourage the use of alternative water sources within Fort Bend County.

The FBSD has implemented a District Regulatory Plan requiring well owners to:

  • Develop a GRP and submit it for approval by 2008.
  • Ensure that groundwater comprises no more than 70% of total water used by well owners and their customers starting January 2014.
  • Further reduce groundwater use to no more than 40% of total water demand beginning in 2027. (Individual wells serving only one home are exempt from these requirements).

Missouri City’s GRP: A Collaborative Approach

Recognizing that individual water providers might struggle to meet the FBSD mandates independently, the Missouri City Groundwater Reduction Plan (GRP) was established. This coalition of water providers, including FBMUD47, operates within the City, its extraterritorial jurisdiction (ETJ), and some neighboring water systems. By working together as a region, the Missouri City GRP can more effectively meet the FBSD’s reduction goals.

How Missouri City’s GRP Reduces Groundwater Use

The cornerstone of the Missouri City GRP’s strategy to reduce groundwater use is the integration of surface water from the Brazos River and Oyster Creek. This involves:

  • Purchasing reliable surface water sources from entities holding Brazos River water rights.
  • Constructing water plants to treat the surface water.
  • Developing a transmission system to deliver the treated water to users.

The City of Missouri City currently purchases Brazos River water from the Gulf Coast Water Authority. A Regional Surface Water Treatment Plant was constructed in 2012 and expanded in 2020 to meet the needs of a growing Missouri City and Sienna, and to comply with FBSD requirements. Additionally, the GRP includes projects for the reuse of water for irrigation, lake amenities, and other purposes.

What is the GRP Pumpage Fee and Why the Increase?

The GRP pumpage fee is a charge levied on groundwater users to help fund the initiatives of the Missouri City GRP. The upcoming increase to $2.63 per 1,000 gallons for groundwater users is necessary to support the ongoing projects and operational costs associated with transitioning to surface water and maintaining the required infrastructure.

These projects include:

  • Regional Surface Water Treatment Plant construction and expansion.
  • Development of transmission lines.
  • Maintenance and operations of facilities.
  • Capital Improvement Projects.
  • Water reuse projects (utilizing treated water from wastewater plants).

It’s important to note that the Fort Bend Subsidence District imposes a substantial disincentive fee – currently $6.50 per 1,000 gallons – on any well owner not complying with the District Regulatory Plan. By participating in the Missouri City GRP and contributing through the GRP pumpage fee, groundwater users avoid this much higher penalty.

The Difference in Fees and Administrative Costs

While surface water is generally more expensive to procure and treat than groundwater, the GRP fee helps distribute the costs across all water users to maintain a lower overall cost. Groundwater users contribute to surface water costs but at a lower rate than surface water users, as they also pay for groundwater treatment. The difference in fees primarily covers the cost of groundwater treatment.

Water providers, such as FBMUD47, may also add a small administrative cost to the GRP fee to cover expenses related to collection, dispersing, and reporting requirements. FBMUD47’s GRP Fee charged to its customers will increase from $2.19 to $2.63 per 1,000 gallons.

Success of the Missouri City GRP

The Missouri City GRP has proven successful in its mission. It is currently exceeding the 40% groundwater reduction mark mandated by the FBSD for 2027, and additional projects are underway to ensure continued compliance.

The GRP fee increase is a vital component of Missouri City’s long-term water management strategy. By transitioning to surface water sources, the community is proactively addressing land subsidence and securing a reliable water supply for future generations. Residents with questions are encouraged to contact the District’s Operator, Municipal District Services at 281-290-6500.

WATERLINE FLUSHING NOTICE

Flushing of the District’s water lines will be performed during the weekdays of September 22, 2025 by the District’s water and wastewater operating company, Municipal District Services (MDS). All water mains shall be flushed using each fire hydrant throughout the neighborhood. Flushing shall begin each morning at 8am until 4pm during this week.

FAQs

What is flushing?

Flushing is a process that rapidly removes water from the District’s water piping system, similar to the process of flushing a car’s radiator. Flushing uses water force to scour out materials that accumulate in the District’s pipes. Water pipes are usually flushed by opening fire hydrants, where the discharged water flows off the streets the same as rainwater.

Why are we flushing?

Imagine driving down the road at less than 1-1/2 miles per hour. That is about the rate that water moves through underground pipes. This slow movement causes sediment like rust and mineral particles to build up over time and accumulate along the pipe’s bottom. A buildup of bacteria known as “biofilm” can also coat the pipe’s inner surface. This combination of sediment and bacteria can restrict water flow in the pipes and contribute to the pipe corroding. Rapid water pressure changes, such as water main breaks and the use of fire hydrants, can stir up the sediment and dislodge deposits lining the pipe, resulting in “discolored water” appearance. Periodically flushing water pipes removes the sediment and biofilm buildup, maintains our District’s infrastructure, and increases water quality.

Isn’t flushing a waste of water?

No. Any overall increase in the amount of water used in flushing is a small price to pay in maintaining water quality and the integrity of the piping system.

How will this affect you?

Usually, you will not be aware that flushing is even taking place in your neighborhood. Flushing is conducted between 8 a.m. and 4 p.m. Monday through Friday. Half of the District’s fire hydrants will be opened to flush the water pipes. It takes about 30 minutes to flush each hydrant. While the hydrant is being flushed, the homes on that block may experience discolored water or a drop in water pressure. Your water service should not be interrupted. If you have no water pressure, please notify MDS at 281-290-6500. The only sign that a crew has been in your neighborhood may be standing water in the roadway.

What should you do if you turned on a faucet and the water coming out is discolored?

Should a reddish, yellow, or brown tint to the water appear, do not be alarmed. It is recommended you do not use the water or do laundry for about two hours; this will give the sediment time to settle. After you have waited for this time period, run your faucets for about five minutes to make sure the water is clear. If the water does not clear within a couple of hours, notify MDS at 281-290-6500 24-hours per day. The District will not be responsible for damages to clothing, etc.
