"How do I get frogs in my backyard pond?" is without a doubt the most common enquiry of the hundreds received at the Amphibian Research Centre.

The objective of sewage treatment is to produce a disposable effluent without causing harm to the surrounding environment, and prevent pollution . [ 1 ] Sewage treatment is the process of removing contaminants from wastewater and household sewage , both runoff ( effluents ), domestic, commercial and institutional. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce an environmentally safe fluid waste stream (or treated effluent ) and a solid waste (or treated sludge ) suitable for disposal or reuse (usually as farm fertilizer ).
How does wastewater treatment work? Wastewater treatment can encompass a number of steps, which filter, clarify and clean wastewater from start to finish. Currently, the CRD region employs a variety of wastewater treatments, some of which filter and some of which provide secondary treatment.
