Reclaimed Water

Reclaimed water can be used in a vari­ety of ways for pur­poses that typ­i­cally do not require drink­ing water qual­ity. Reclaimed water is a great option for water con­ser­va­tion and has res­i­den­tial, com­mer­cial, indus­trial, and insti­tu­tional uses. Reclaimed water sys­tems man­age waste­water and allow it to be safely reused for many pur­poses including:

- land­scape irrigation

- toi­let and uri­nal flushing

- sup­ply water for orna­men­tal ponds

- cool­ing water for com­puter or elec­tronic equipment

Howard County’s Water Reuse Divi­sion over­sees the pro­gram. Please visit their web­page for more info.


Howard County Sup­plies NSA With Cool­ing Water

Howard County sup­plies the National Secu­rity Agency (NSA) with mil­lions of gal­lons of treated waste­water per day for a com­puter cool­ing sys­tem. NSA installed a pump sta­tion and pays the County for the treated waste­water that would oth­er­wise be dis­charged directly into the Lit­tle Patux­ent River which flows to the Chesa­peake Bay. The major­ity of the water sent to NSA will evap­o­rate dur­ing the cool­ing process but some water con­denses and is dis­charged in the Lit­tle Patux­ent River. Howard County and NSA worked together to ensure the river lev­els will not be affected with the reduced out­put, nor will the tem­per­a­ture of the dis­charg­ing water alter the river’s ecosys­tem. By recy­cling this waste­water for another use (cool­ing), NSA is not adding stress to our ground water sup­ply or uti­liz­ing drink­ing water from the reser­voir systems.
