Underground storage tanks minimize wastewater plant’s footprint onsite
At a glance
Pretreatment of wastewater by commercial and industrial facilities ensures that the wastewater entering into a sewer system under the control of a publicly owned municipality meets its municipal sewer discharge agreement. This prevents health and safety issues to the public or the environment, and improves opportunities for the reuse of wastewater and sewage sludge.
Our response
Our team of wastewater, design, and contracting professionals designed and built a process wastewater pretreatment plant at a new state-of-the-art manufacturing plant in Hamilton, Ontario, Canada. The standalone building was required to meet Health Canada regulations and site limitations; therefore, the wastewater team built a precast concrete building with underground concrete storage tanks to minimize the footprint onsite.
The new facility had yet to establish a waste quantity and quality; therefore, the team designed a system flexible enough to handle a wide range of flow and waste characteristics, including the ability to operate the plant easily and cost-effectively while ensuring zero downtime.
The treatment process includes five underground storage tanks to process multiple waste streams, rotating drum screens, dissolved air flotation, sludge management, and a chemical addition system. Under a tight deadline and budget, we confirmed. that the plant was operational and commissioned prior to the main plant’s completion.
The impact
- Turnkey project gave client the comfort of dealing with one entity for design and construction
- cost-effective system reduced down time while operational
- Completed the project ahead of schedule and under budget
