Bypass Wastewater Treatment

As seen in The Wave, Spring 2018.

Most of our nation’s existing wastewater treatment networks are now facing the effects of aging as they struggle to keep up with increasing demand, while receiving insufficient funding to repair or replace components.


As a result, there has been an increase in demand for repairs and upgrades and sometimes emergencies, which must be quickly addressed to maintain operations to protect public health. When an operator is faced with the need to perform any of these tasks, continuity of service is a must. So, what can an operator do when faced with an immediate need to repair or replace a wastewater treatment facility without disrupting a community’s usage?




Pump & Haul to an Alternate Facility

One option to continuing wastewater treatment service is via pump and haul to an alternate facility. This allows for the wastewater to be treated locally and prevents customers from facing any disruptions to service. In order to initiate this process, plant owners must first locate a facility in close proximity that is willing and able to receive your wastewater. If nearby plants are close to reaching their maximum capacity, they will not be able to treat any additional wastewater.


Once you find a receptive plant consider all costs associated with this method, which will include:

  • Mobilization / demobilization of equipment
  • Day rates
  • Disposal fees
  • Truck rates
  • Fuel charges
  • Labor costs
  • Discharge cost

Of course, these fees will vary by state and season, with extreme hot or cold temperatures increasing costs. Also note, environmental factors will also need to be considered when having to haul wastewater. Spillage and leak response costs need to be factored into the budget when considering this option.


Temporary Bypass Treatment Plants

Alternatively, you may choose to install a bypass treatment facility onsite to receive and treat your wastewater. Once the capacity needs have been understood, a bypass plant can be quickly mobilized to treat temporary requirements.


AUC Group owns and maintains a fleet of portable, modular components, designed for rapid deployment and demobilization and include a wide variety of treatment options:  aeration, digester and clarifier tanks. These systems are designed to treat flows up to 1,000,000 gallons per day.

Take Harris County Municipal Utility District #8, for example. They were faced with a sudden need to treat flow as their plant underwent emergency repairs. After an initial assessment, AUC Group was able to provide a custom quote to meet the needs of their existing flow and install a temporary 0.4 million gallons per day (“MGD”) wastewater treatment plant to keep the facility online. This also prevented the district from facing government fines by preserving permitted effluent parameters.
