Citizens Reservoir Gets Penetron Treatment to Help Secure Water Supply for Indianapolis

The $30 million Citizens Reservoir, completed in January 2021, serves the critical purpose of securing a sufficient drinking water supply for the rapidly growing Indianapolis metropolitan area in Indiana. To ensure that the new drinking water treatment plant of the project is durable and resistant to water, Penetron Admix SB was specified. The non-toxic, NSF-61-certified solution was used to make the concrete structures of the water treatment plant waterproof.

The Citizens Reservoir, located adjacent to the Geist Reservoir, stores captured rainwater and also provides an additional 3.2 billion gallons of water storage to the region, making the water supply more robust and drought-resilient. With the Citizens Reservoir pumping 25 million gallons of water daily into the Geist Reservoir, they then send the treated water to the Citizens Energy water treatment plants in Indianapolis.

Given the proximity of the project to water, it was crucial to use a robust waterproofing solution to ensure the longevity and durability of the concrete structures. The Penetron Group worked with concrete ready-mix supplier Shelby Materials to develop the optimal concrete mix for the new water treatment plant. Specifiers recommended Penetron Admix SB for its durability and waterproofing properties, making the concrete structures impervious to the penetration of water or liquids from any direction.

The ease of dosing the concrete mix with the pre-measured soluble bags of Penetron Admix SB eliminated the need for pre-weighing the admixture before adding it to the mix. The durability and self-healing properties of the concrete virtually eliminate any downstream maintenance costs, making it an ideal solution for water treatment plants in constant contact with drinking water resources. With the repurposing of a nearby limestone quarry to store excess water, the Citizens Reservoir represents a triumph of engineering and a concrete solution for the sustainable development of the region’s water supply.
