<br /> Re: D. Brian Fulmer Sewer Plan
<br /> File No. 139Gen
<br /> Dear Lyle,
<br /> We have reviewed the proposed sewer plan submitted for the D. Brian Fulmer property
<br /> located at the southeast corner of U.S. Highway No. 12 and the Burlington Northern
<br /> Railroad, in the Northeast Quarter of Section 32. We would recommend the following
<br /> modifications.
<br /> The pump should be designed for a Total Design Head (TDH) of 115 feet. This allows
<br /> for the static head when MWCC's Maple Plain Lift Station is pumping (1079 - 967 =
<br /> 112 feet) and approximately 3 feet of head losses due to the 2" forcemain, check valve
<br /> and gate valve. The developer's engineer should check with the pump manufacturer
<br /> (Aurora/Hydromatic Pumps, Inc.) to determine of the motor will be overloaded if it is
<br /> pumping against a lesser head. For example, if the MWCC station is pumping at 1150
<br /> GPM or if it is not operating. The proposed lift station wet well depth should be a
<br /> minimum of 2' below the inlet pipe and 3' below the discharge pipe as shown on the
<br /> enclosed manufacturer's detail. The developer's engineer should check with the MWCC
<br /> regarding their tap connection requirements and should complete an "Application and
<br /> Permit for Connection to, or use of, Metropolitan Waste Control Commission Facilities".
<br /> Please contact me at this office if you have any questions regarding this matter.
<br /> Yours very truly,
<br /> BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INC.
