Municipal wastewater collection systems are constantly exposed to sulfuric acid that is created by hydrogen sulfide out gassing. This exposure to a low pH environment causes the Portland cement in the concrete to be compromised. The standard means of protecting Portland cement concrete structures is using a coating or lining. Polymer concrete does not require any coatings or linings to protect if from this corrosion. This paper will demonstrate how a corrosive resistant polymer concrete was utilized on a project to prevent the corrosion of three ten foot diameter precast structures that are approximately 110’ (33.52 m) deep each.

Keywords: hydrogen sulfide, sulfuric acid, manholes, polymer concrete, pump station, lift station, corrosion, non-corrosive, H2S, pH, polymer, precast

While sewer renewal technologies currently being used for the repair replacement and/or rehabilitation of deteriorating wastewater collection systems are generally effective there is still room for improvement of existing technologies and for the development of new technologies. Many utilities are seeking innovative rehabilitation technologies particularly for large-diameter pipes. However information about these emerging technologies is not always readily available. As part of the U.S. Environmental Protection Agency (USEPA)’s Aging Water Infrastructure Program a field demonstration program of innovative rehabilitation technologies was initiated with the purpose of: (1) gathering reliable performance and cost data for new technologies; and (2) making the capabilities of these technologies better known to the industry. This paper describes the demonstration of an innovative spray-applied fiber-reinforced geopolymer mortar for rehabilitating a 60-in. reinforced concrete pipe approximately 25 ft deep in Houston TX. The demonstration section was 165 ft of severely deteriorated pipe that terminated at a wastewater treatment plant (WWTP). Unique aspects of this project included: (a) the use of an innovative and emerging large-diameter structural rehabilitation technology on a severely deteriorated pipe located beneath a large open stormwater channel; (b) an independent third-party assessment of the technology; and (c) difficult flow control issues at the WWTP.

The County of Madison, MS. experienced severe degradation of a major pump station in their system that was less than 10 years old. They contracted with Waggoner Engineering of Jackson, MS. to design a rehabilitation system as well as increase the structural integrity with the addition of some support walls. The project created scheduling issues due to the addition of new concrete structures to the pump station. The use of innovative coatings technologies that offered the ability to apply corrosion resistant linings over green concrete structures, dramatically enhanced the project schedule and reduced overall costs.
