MCTX RSWTP Closed for Phase II Expansion Construction; During Shutdown, MUD-Operated Wells Are Being Utilized

CONTACT: Stacie Walker — 281.403.8530

As part of the Phase II expansion of the Missouri City Regional Surface Water Treatment Plant (RSWTP), service from the facility has been temporarily halted and, in the interim, water is being supplied by area municipal utility districts (MUDs) from ground water wells.

Due to the change in the source, the City has received a number of inquiries from residents and the media about the difference in the water. As a result, staff has compiled a list of frequently asked questions and responses on the issue:

When was the RSWTP temporarily shut down?
Tuesday, Jan. 28.

When is the plant expected to be back online?
By Friday, Feb. 14.

Why was the plant shut down?
According to City officials, the RSWTP is currently being expanded from its 10 million gallons a day (MGD) capacity, to 20 MGD. During this construction, the current 10 MGD plant needs to be shutdown intermittently to facilitate construction and integration with the expanded plant units.

What communities are affected by the shutdown?
The areas affected are: all of Sienna, the portions of Riverstone in Missouri City’s ETJ and inside Missouri City limits, and Colony Lakes Subdivision.

Does this issue impact businesses and schools?
Yes, those that are located in the areas specified above.

How are these areas receiving water now?
During this temporary shutdown, existing ground water wells (operated and managed by the Municipal Utility Districts) are being used to augment potable water supplies in the affected areas.

Is the water safe?
According to the MUD operators, the “treated ground/well water” meets or exceeds regulatory standards for potable water and is safe for consumption.

Will there be any taste/odor/color differences?
In general, when there is a change in water supply source from “treated surface water” to “treated ground/well water,” consumers may notice a subtle difference in the taste/odor/color of the water.

Were impacted consumers notified?
No, according to City officials, as there was no interruption in water supply.

Severe Weather Update

The Tropical System that we have been watching over the past couple days has been officially upgraded to Tropical Storm Imelda. The system has produced sustained winds of 40 mph with gusts near 50 mph near Freeport. With its development and the formation of a more well defined surface circulation, we are gaining slightly more confidence in the rainfall forecast and amounts. TS Imelda’s center is forecasted to move in a north to north-northwesterly direction along the SH 288 corridor through Brazoria and Harris County this evening and overnight. This should bring the heaviest rainfall along the center and to the east of its track.

Depending on the final path and speed of TS Imelda, we have the potential for rainfall amounts between 4 to 6 inches with isolated amounts 10 to 15 inches through Thursday. As mentioned, the heaviest rainfall should be along and to the east of the SH 288 corridor, but this system could produce rainfall intensities between 2 to 3 inches per hour. Although Tropical Storm Winds are possible for areas along the coast, our biggest threat continues to be the rainfall which could cause street and small stream flooding. At this time, there is no forecasted threat of flooding along the Brazos River, but we will continue to monitor the conditions and provide updates as needed.
