A. Location: Manholes shall be required on all sewer main lines and shall be located at each street intersection, or as required by the "Idaho Standards For Public Works Construction", and the Oregon code. Where the distance between two (2) manholes is greater than three hundred feet (300'), an additional manhole shall be constructed; provided, however, that if the distance between two (2) manholes is greater than three hundred feet (300') but less than three hundred fifty feet (350'), the city engineer may waive the requirement for an additional manhole if he or she shall first make a written determination that it is hydraulically feasible to dispense with the additional manhole. The burden of proof lies with the applicant's engineer in the written determination to waive an intermediate manhole.
B. Cul-De-Sac: Where a sewer main shall be constructed in a cul-de-sac street of less than one hundred fifty feet (150') in length, a sewer main may terminate in an approved lamp hole cleanout, or an approved manhole. If the cul-de-sac street is greater than one hundred fifty feet (150') in length, it shall terminate only in an approved manhole.
C. House Laterals: No house lateral shall connect directly into a manhole unless the city engineer shall determine it is infeasible to connect with the sewer line available to the property to be connected. House laterals on cul-de-sac streets shall connect only to the down flow side of the manhole. (Ord. 624-08, 8-12-2008)
