Grand Mound Town Hall and Waterworks Historic District, also known as Hose house, pump house, is a historic district located in Grand Mound, Iowa, United States.

It was designed by Gustav Ahlff, who owned a local lumber yard, weigh station, and clay tile manufacturing company.

The original bell is now part of a monument located in front of the pump house.

It is thought that an area on the main floors southwest corner may have been the location of an early jail that consisted of a single cell.

[2] Grand Mound installed its first water system in 1898 and built a frame building to house it.

Oral tradition in the town relates that the original pump was destroyed by an explosion caused by a spark set off by the fuel.

A prefabricated pavilion was built behind the pump house in 1968 for picnics that are routinely held on the property.

The tank for the previous water tower, located on the square at Fulton and Smith Streets, had been condemned in 1914.
