If effluent is to be pumped, what must be provided?

The correct answer highlights the essential components that must be in place when effluent is to be pumped. Having a high-water alarm is crucial as it alerts users to potential overflows or failures in the pumping system. This added layer of safety helps to prevent environmental contamination and ensures compliance with regulations.

The requirement for the pump to be in a separate chamber is critical to protect the pump from solids and debris that may be present in the effluent, ensuring that the pump operates efficiently and reduces the likelihood of clogs. This separation is a critical design consideration in many wastewater systems.

Additionally, incorporating a check valve in the line is necessary to prevent the backflow of effluent. This is vital in systems where effluent needs to be moved to a higher elevation or to additional treatment systems, as it helps maintain a one-way flow, avoiding any potential contamination of the previous systems.

Together, these components create a robust pumping system that is reliable and effective for handling effluent. Other options do not encompass all these requirements, which are fundamental for safe and efficient management of pumped effluent.
