The collection of assessments to be levied to pay for the location, construction, maintenance or repair of any ditch, levee, dike or watercourse, shall not be enjoined or declared void, nor shall such assessment be set aside in consequence of any error, omission, or irregularity committed or appearing in any of the proceedings provided for in sections 31-301 to 31-369. No injunction shall be allowed restraining the collection of any assessment until the party complaining shall first pay to the county treasurer the amount of his assessment, which amount so paid may be recovered from the district in an action brought for that purpose in case the injunction is made perpetual.
