Wastewater and Water Treatment Plant Repair

Epoxy Design Joint Repair

Epoxy Design Systems provides concrete repair and restoration for wastewater & water treatment. Throughout every community, these large concrete structures support a systematic, sequenced system to treat liquids. The wastewater plant separates solid / solution waste for solids reuse in soils / compost, so treated water can be reused as grey water for irrigation, in commercial cooling process, and liquid transfer to a water treatment plant. The water treatment plant processes liquid to supply safe, potable, drinking water for commercial and residential use.

Each plant consists of several concrete basins, mechanical motors and pumps, large circulating devices, underground drain collections, aeration methods, waste separation, chemical injection and laboratory analysis. All concrete structures must withstand constant temperature changes / liquid pressures, resist chemical damage, remain water tight, sustain twenty-four-hour operation, and meet public demands. In time, each concrete structure will become less efficient due to leaks, erosion, chemical damage, contamination, and transfer deficiencies. When this occurs the individual concrete structure(s) is taken “off line” for planned restoration maintenance.

Concrete integrity, corrosion control, cracks, leaks, joint failures and chemical damage are the most common items which may quickly degrade plant efficiency requiring restoration. Water leaks and concrete degradation are recurring MAINTENANCE items requiring concrete joint restoration, new joint sealant, and concrete spall repair, epoxy or urethane grout injection of cracks, resurfacing concrete vertical surfaces, to provide proper cover over reinforcement applying epoxy/urethane protective surface coatings, and sealing wall penetrations. Control of infiltration, carrying soils in to the plant prevents additional solids to treat and reduces wear on mechanical impellors and pumps. It is critical to make timely repairs and to monitor plant operations. When the decision is made to shut down or go “off line”, it is essential to have a well-defined, comprehensive scope of work in place, all work items are fully funded and there is a realistic timeline required to restore the structures. This type of planning will require an engineered survey, defined scope, repair means and methods, and employing a highly qualified concrete restoration contractor with extensive water and wastewater plant experience to complete all repairs. Anything less than this will create an ineffective band-aid approach, with lowered plant life expectancy.

Some additional considerations:

  • Develop a continuing plant maintenance survey procedure, today, along with a team of qualified professionals to provide engineering and concrete restoration repairs.
  • Water as a valuable commodity, requires conservation and efficient operations, as safe drinking water is crucial for all life.  
  • Observation for chemical attack
