Stormwater pumping stations are systems designed to remove excess rainwater from low-lying areas that cannot drain naturally. They work by collecting water in a sump or wet well and pumping it to a higher elevation or drainage point, preventing flooding during heavy rainfall. Pumping stations can be combined with storage basins or green infrastructure to manage peak flows more efficiently.

Small scale stormwater pumps can be installed for domestic use to prevent the flooding of basements and gardens, but are also used in large scale drainage systems. 

Feasibility & Local Applicability

Prefabricated pump stations can be adapted to limited space and integrated with existing drainage networks. However, they require reliable electricity and regular maintenance, which must be factored into planning.

Co-benefits

Beyond flood prevention, pumping stations protect roads, homes, and businesses from water damage, reducing economic losses. They also improve public health by minimizing stagnant water, which can attract mosquitoes and increase disease risk. When combined with green infrastructure, they can enhance urban aesthetics and resilience. 

Equity & Vulnerability Considerations

Community engagement in planning ensures that systems serve those most at risk. Affordable maintenance programs and training for local technicians can help sustain operations and create jobs.

Costs

Medium | Costs depend on station size and capacity. Small-scale pumps for neighborhoods are relatively affordable, while large stations for urban drainage require significant investment in equipment, installation, and energy supply.
