When the need for two new reclaimed water storage tanks arose in Katy, Texas, the owner, Cinco Southwest MUD No. 1, and the consulting engineer, AECOM, specified AWWA D110, Type III prestressed concrete tanks to provide the sustainable, reliable solution needed to complement a plant upgrade project designed around sustainability.

Cinco Southwest MUD No. 1 services the master-planned community of Cinco Ranch, located approximately 25 miles west of Houston in the greater Katy, Texas, area. The MUD is part of the larger Cinco Ranch MUD system that services approximately 32,000 residents and is managed by the North Fort Bend Water Authority.

Prestressed concrete tanks from Preload are environmentally sustainable and virtually maintenance-free.

Given the rising cost of water, the MUD has taken a proactive step to keep water bills low by constructing the Southwest Reclaimed Water Plant. When completed, the new plant will shift the community’s dependence from potable drinking water to reclaimed water for irrigation purposes in medians. While reclaimed water projects are not uncommon in the U.S., this project is unique to the area. The water treated at the upgraded plant will meet Texas state standards for reusing water for landscaping and will be stored in two 564,000-gallon Preload AWWA D110, Type III wire-wound prestressed concrete tanks.

The process of reclaiming water and achieving sustainability go hand-in-hand as utilities work to find solutions to the water needs of the world and an ever-growing population. In this light, an additional benefit of the new AWWA D110, Type III prestressed concrete reclaimed tanks is their sustainability. The new tanks are made of concrete and therefore will provide generations of virtually maintenance-free service avoiding costly and environmentally challenging recoating applications.

Project Details

The new 0.564 MG ground storage tanks are AWWA D110, Type III certified with an inside diameter of 61 feet, side water depth of 25 feet, and a cast-in-place dome. Preload installed approximately 95,200 linear feet of prestressing wire on 19 panels per tank. The panels measured 25’11”x10’3”x4.5” and weighed in at 7.5 tons/panel requiring a 135-ton crane for erection.

The company is proud to be part of Cinco Southwest MUD No. 1’s investment into reducing the cost of water, conserving it and building sustainable infrastructure through this unique reclaimed water project.

Preload is exhibiting at WEFTEC.16, Booth 3308. For more information, visit www.preload.com.
