Stormwater runoff from Sugar Land flows to Oyster Creek.In the near future, additional water supplies will be pumped through Oyster Creek from the Brazos River to serve as the primary potable water source for the City of Sugar Land. Drinking water is treated to remove harmful contaminants and make it safe for human consumption. Higher concentrations of contaminants in our stormwater require more treatment to make the water safe for us to drink.
