STORM WATER & LID SESSION

Ever since humans began living in concentrated village or urban settings,

stormwater runoff has been an issue.

During the Bronze Age, housing took a more concentrated form, and

impervious surfaces emerged. This lead to the Urban Sprawl Age.

Some of the early incorporation of stormwater engineering is evidenced in

ancient Greece.

An early specific example of stormwater runoff system design is found in the

archaeological recovery at Minoan Phaistos on Crete.

Runoff Volumes Increase Pollutants Increase

SO, WHAT’S THE BIG DEAL?

As community grow the volume of storm water discharged from

that municipality as well as pollutants generated within the

municipal jurisdiction.

San Joaquin River

Kings River

A watershed is the area of land that

catches rain or snow which drains

or seeps into a ponding basin,

stream, river, lake or groundwater

Our watershed is made of the

snow on the Sierra Nevada

Mountains, the Kings and San

Joaquin Rivers, Millerton and

Pine Flat Lakes, Ponding

Basins and our Groundwater

Aquifer.

2. Water is pumped out of our

groundwater aquifer and delivered to

homes, schools and businesses.

The primary source of

our drinking water is

groundwater.

3. Wastewater leaves buildings where

it flows to the City wastewater

treatment facility.

1. Rain and the water that flows over

our City flows to ponding basing

where it recharges our groundwater

aquifer.
