Incorporated October 26, 1939



Our mission is "To provide safe and reliable water and wastewater services in an efficient, cost effective

and environmentally friendly manner resulting in a high level of satisfaction among our customers."




Manheim Area Water & Sewer Authority (MAWSA) is a small water and wastewater Authority supplying approximately 3,000 water and 2,300 wastewater customers in the Manheim area. The area of service is the Borough of Manheim and portions of Penn and Rapho Townships, Lancaster County, Pennsylvania. MAWSA receives and treats an average of 83,000 gallons of hauled waste and septage from various haulers and sites.

MAWSA's current customer water demand is roughly 450,000 gallons of water per day (GPD) with a permitted capacity of 1,050,000 GPD and SRBC draw capacity of 936,000 GPD.

The wastewater plant permit capacity is 2,300,000 GPD hydraulic and organic capacity, with average flows of 800,000 GPD from residential, commercial, and industrial customers. 



Beginning Monday, April 15 and through Friday, April 19, Mountainside Excavating will be working on a water main break on the southern portion of Market Square (the eastbound lane). Miller Pipeline hit MAWSA’s 4” water main on Monday, April 8, triggering a boil water advisory. As an additional result of the water main damage, water being provided to customers via services connected to this line will need to be moved to the 10” water main in the middle of the Square.

Notifications were delivered to the residents and businesses of Market Square. The eastbound lane of Markets Square will be closed, and a detour will be posted upon approval.

Please be mindful of the work area and revised traffic pattern for your safety and the safety of our crews.


The boil water advisory has been LIFTED for the odd numbered, eastbound, side of Market Square. Properties from 1 through 57 Market Square no longer have to boil water prior to use.
