Kan. Admin. Regs. § 5-40-53 - Drawdown pipes
(a) Except as
specified in subsection (b), each dam shall be equipped with a drawdown pipe
that meets the requirements for a pipe as specified in K.A.R. 5-40-50. A valve
or gate shall be installed in the pipe so that the controls are accessible and
damage from freezing is prevented. Drawdown pipes may be incorporated into the
primary spillway.
(b) The
installation of a drawdown pipe shall not be required for a low-impact dam if
the chief engineer determines that both of the following criteria are met:
(1) The failure to install a drawdown pipe
will not prejudicially and unreasonably affect the public interest and the
public safety.
(2) The drawdown
pipe is not necessary to administer water rights.
(c) Each drawdown pipe shall have the
capacity to evacuate 90 percent of the volume of the permanent pool in 14 or
fewer days assuming no inflow into the reservoir, but in no case shall the
drawdown pipe have an internal diameter of less than four inches. The inlet of
the drawdown pipe shall be constructed to reduce the likelihood of plugging.
