426 Minneapolis Sewer System 



The further development of the North Minneapolis sewer systems 

 was determined by the establishment in 1889 of the new pumping 

 stations for the city water supply at 42d Av. N. in Camden Place and 

 the later North East Station still higher up the river in 1904, with 

 the consequent abandonment of the old pumping stations at the falls 

 and on the Hennepin Id. Thus the new systems could be again 

 planned for the immediate exits of natural drainage areas directly into 

 the river, without the long and expensive circumlocution of the North 

 Minneapolis tunnel system. Thus in 1890 the 20th Av. N. system 

 was begun from the river foot of that street, extending from the river 

 back to Penn. Av., and draining, with its branches, the region of about 

 400 acres between 20th and 25th Avs. N. inclusive. 



The next northerly section between 26th and 32d Avs. N. was 

 begun by the 26th Av. N. system in 1900, which also extends at pre- 

 sent back to Penn. Av. The next drainage area down 33d Av. N. has 

 only as yet been started by a small section back of Lyndale and tem- 

 porarily emptying into the adjacent lower system. For the next drain- 

 age area a trunk sewer will be built this summer from Wash. Av. 

 down 38th Av. N. to the river, for the immediate purpose of making 

 travel somewhat passable for the enormous and heavy wagon traffic 

 of lumber, bricks and farm produce down Wash. Av. thru Camden 

 Place. A still further north system will be started next year on 42d 

 Av. N. The surface deposit of clay all over North Minneapolis 

 makes these rapid extensions of the sewer systems of the utmost ne- 

 cessity in order to drain the many sloughs formed in every pocket 

 depression of the clay, to make the streets passable in wet weather, 

 and to afford house connections where cess pools have no filtration. 



The sewer system for North East Minneapolis was begun in the 

 same year, 1889, and with the same plan as the North Minneapolis 

 tunnel system for discharging below the old pumping stations at the 

 falls. A tunnel was begun under the lime rock at the mill race of 

 the Pillsbury A mill at 4th Av. S. E. It extended up Main St. to 

 Marshall, and thence up Marshall St. to 22d Av. N. E. A branch tun- 

 nel was made in 1886 up 3d Av. N. E. nearly to Central Av., with a side 

 branch going up 2d St. N. E. to Broadway. 



From the end of this 3d Av. N. E. tunnel a 5i/^ ft. sewer was con- 

 tinued with two main branches, one across Spring St. and up Fill- 

 more, the other turning up Central Av. to 30th Av, N. E. at present. 

 Likewise from the end of the Marshall St. tunnel a large concrete 

 6y2 ft. sewer has been built up 22d Av. N. E. to Monroe, from whence 

 it is planned to cross Central Av. All North East Mpls. is as yet 

 served by only this one system, with its many sub-branches. With 

 the closing of the lower pumping stations however, an overflow has 

 been provided directly into the river at the foot of 3d Av. N. E. 



The extreme South East section of the city, below 16th Av. S. E., 

 was provided for by the Oak St. system, begun in 1888 from the 

 foot of Oak St. and turning both ways on University Av., and by the 

 Hamline Av. system, which was built up that hill from the river in 

 1904 and winds about among the hills of Prospect Park.
