Water & Wastewater Infrastructure Engineering
Construction engineering for water treatment and wastewater infrastructure where concrete rehabilitation, structural integrity, and multi-discipline coordination are critical. Direct experience on the Bolivar Wastewater Treatment Plant rehabilitation program for SA Water.
Engineering Overview
Water and wastewater infrastructure engineering addresses the structural rehabilitation, concrete repair, and multi-discipline coordination required to maintain and upgrade treatment plant structures. JCY Construction Engineering provides specialist structural and construction engineering support for water sector clients, focusing on concrete rehabilitation of process structures, coordination between structural, electrical, and mechanical disciplines, and construction methodology for work within operational treatment facilities.
Water & Wastewater Engineering Challenges
Treatment plant structures operate in aggressive environments that accelerate concrete deterioration and complicate rehabilitation works.
Concrete Deterioration in Aggressive Environments
Wastewater treatment structures are exposed to hydrogen sulphide gas, chloride attack, and constant moisture -- conditions that accelerate reinforcement corrosion and concrete degradation. Rehabilitation must address the root cause of deterioration, not just the visible symptoms. Selecting the correct repair material, protective coating, and drainage improvements requires understanding both the structural engineering and the chemistry of the exposure environment.
Working Within Operational Facilities
Treatment plants cannot be shut down for rehabilitation. Construction must be staged to maintain treatment capacity, with individual process units taken offline while parallel units continue operating. This requires careful sequencing, temporary bypass arrangements, and coordination with operations teams to ensure environmental licence compliance throughout the rehabilitation program.
Electrical & Mechanical Coordination
Treatment plant rehabilitation typically involves structural concrete repairs alongside electrical switchboard upgrades, mechanical equipment replacement, and process control modifications. Coordinating these disciplines -- ensuring structural openings align with new mechanical penetrations, and that concrete repairs do not conflict with electrical conduit routes -- is essential to avoid construction clashes.

Featured Water Infrastructure Project
Bolivar Wastewater Treatment Plant
The Bolivar WWTP is South Australia's largest wastewater treatment facility, serving metropolitan Adelaide. Jerome provided construction engineering support for the concrete rehabilitation program addressing deterioration of process structures exposed to hydrogen sulphide and other aggressive wastewater environments.
The scope included structural assessment of deteriorated concrete elements, specification of repair materials and protective coatings suited to the exposure conditions, coordination between structural rehabilitation and concurrent electrical and mechanical upgrade works, and construction methodology for rehabilitation within the operational treatment plant.

Water & Wastewater Engineering FAQ
JCY provides concrete rehabilitation engineering, structural assessment of treatment plant process structures, electrical and mechanical coordination, protective coating specification, construction methodology for operational facilities, and construction verification for water and wastewater infrastructure projects. Our focus is on the structural and construction engineering aspects of treatment plant rehabilitation.
Jerome Coly provided construction engineering support for the Bolivar WWTP concrete rehabilitation program. Bolivar is South Australia's largest wastewater treatment facility serving metropolitan Adelaide. The work included structural assessment of deteriorated concrete elements, specification of repair materials for aggressive wastewater environments, and coordination with concurrent electrical and mechanical upgrade works.
Wastewater structures are exposed to hydrogen sulphide gas (H2S), which converts to sulphuric acid on concrete surfaces, causing severe concrete deterioration. Combined with chloride attack from saline wastewater, constant moisture exposure, and carbonation, these conditions accelerate reinforcement corrosion and concrete degradation far beyond what occurs in normal atmospheric exposure. Without rehabilitation, structural capacity is progressively reduced.
Treatment plant rehabilitation typically involves concurrent structural concrete repairs, electrical switchboard and cable upgrades, and mechanical equipment replacement. JCY coordinates these disciplines to ensure structural openings align with new mechanical penetrations, concrete repair zones do not conflict with electrical conduit routes, and construction sequencing allows each discipline adequate access without clashing. This coordination prevents costly rework and programme delays.
Yes, and this is typically required. Treatment plants cannot be fully shut down for rehabilitation. JCY develops construction staging plans that take individual process units offline for repair while parallel units maintain treatment capacity. This requires coordination with operations teams, temporary bypass arrangements, and careful sequencing to ensure environmental licence compliance is maintained throughout the rehabilitation program.
