There are many factors that put pressure on water resources which effects the options and requirements for water management. Population growth is a main factor, creating demands for more water and producing additional wastewater and pollution. The increase can have significant negative impacts on local and regional water resources.

Since the buzz word, or phrase I should say, has come up in a few of our previous blog posts, I thought it would be worth a brief survey. Low-Impact Development (LID) is a design and planning scheme that utilizes green infrastructure and stormwater management techniques to mimic the pre-development hydrologic regime of a site. Five fundamental aspects of LID include:
