In this new age of ‘green urbanism’, innovative urban planning often includes thoughtful green solutions that bring benefit both to the community and environment.
While it is true that urban planning is more than good physical design, one can’t deny the fact that sustainable design considerations – right from the early planning phase – would lead to successful final design and construction that can significantly influence our quality of life in the cities.

Urban stormwater runoff is rainwater or snowmelt runoff that runs off the pavement, parking lots, rooftops and other impermeable surfaces in the cities. As the runoff travels to the lowest elevation, it carries with it dirt, trash, toxins and various pollutants – all the way into streams, lakes, rivers, estuaries, or oceans. This polluted runoff affects the water quality in the receiving bodies and causes significant damage to ecosystems. Continue reading “How to manage urban stormwater quality in three steps”
Stormwater ingress to a city’s sewer system through low gully traps, illegal connections, broken pipes or unsealed manholes is known as Inflow and Infiltration (I&I). This can cause overflows, system strains and interruptions.
What is Inflow & Infiltration?
Inflow: Stormwater that enters the wastewater network directly through gully traps, roofs or illegal connections.
Infiltration: Stormwater or groundwater that enters the wastewater network through cracked pipes and leaky or faulty manholes.
