Recent research suggests rain harvesting may have provided the 800 Roman soliders manning Hadrian’s Fort with 10 liters (2.62 gallons) of drinking water per per capita per day during their deployment.
Evidence at Hadrian’s Fort, a strategic Roman outpost along Hadrian’s Wall in northern England, indicates building rooftops were constructed to capture rainfall. The runoff collected in stone-lined tanks, two to six tanks per key building, capable of holding 2 cubic meters (about 528 gallons) of water each.
It’s an amazing feat of foresight, considering Hadrian’s Fort has no internal springs or wells, access to springs or waterways in the region, and an aqueduct supply would have been extremely impractical.

Stormwater is not treated before it flows into the North Platte River, so contaminants that enter the storm sewer system can also contaminate the river.
According to regulation, anything other than rain or snowmelt in the storm sewer is an illicit discharge. However, clean water discharges to the gutter – like pumped groundwater, air conditioning condensation, or irrigation water/lawn watering – are typically excused.
If you see or find evidence of substances other than rain or snowmelt in the gutter or near a storm drain please call the stormwater department 630-8011. If the spill is over 25 gallons or you know the substance is hazardous, please call 911.
Capetown’s crisis is in the spotlight now, but other metropolitan areas could soon follow:
Trees play a critical role in managing our city’s stormwater runoff. Enjoy this interactive poster from the Arbor Day Foundation highlighting the role trees play in urban stormwater management.
