Sienna LID Begins Design of Fourth Pump Station

The Sienna Plantation Levee Improvement District (LID) has awarded a contract to LJA Engineering & Surveying for the design of a fourth pump station in the Fort Bend master-planned community.  “This pump station is the first of several planned capital improvements projects to expand the system ahead of anticipated growth in the Sawmill Lake and future villages,” said Ken Beckman, district president.

The new $7.3 million pump station will house six pumps, each with a capacity of 45,000 gallons per minute for a combined total of 270,000 gallons of water per minute. It will be placed in the southwestern portion of the district approximately 3,000 feet northwest of the current south pump station.

The station will complement the three pump stations already operational within the Sienna LID, doubling capacity in the southern levee system. Two stations currently serve the north area of the district, each station housing four pumps; combined, these two stations can pump out 286,400 gallons of water per minute. A third station, located in the southwestern portion of the district, has six pumps that can operate at 43,250 gallons per minute apiece or a total capacity of 259,500 gallons of water per minute.

Design of the new station is estimated to take seven months with construction expected to begin July 2018. The pump station should be operational by fall 2019.

The 10,800-acre Sienna Plantation is celebrating 20 years of development. Sixteen builders have opened 21 models in Sienna Plantation, where homes are priced from the $250,000s. Learn more at To see how the levee system functioned during Hurricane Harvey, visit
