(a) The governing body of any sewer district shall from time to time cause an inspection to be made and a certified report and detailed account of the maximum connected load, which is at that time being carried, treated and disposed of by the existing system and facilities, including population totals and trends of the district in relation thereof, together with any data necessary to determine the condition and adequacy of the facilities and improvements to serve the existing and definitely calculable demands of the district. The report and account shall be furnished by a competent consulting engineer and shall include the recommendations the engineer finds are necessary.

(b) If it appears from the report, detailed account and recommendations that the collection and treatment system is carrying a connected load in excess of the designed capacity, and if the governing body approves the report and recommendations, it shall submit to the secretary of health and environment a complete copy of the engineer’s report, detailed account and recommendations as to what additional facilities should be provided in order to provide adequate capacity for collection and treatment of the then connected load, or what reasonably may be expected to be the connected load, within a reasonable period of time thereafter. After giving careful consideration to all information, the secretary shall either approve or disapprove the findings of the engineer and of the governing body. If the secretary approves the report, the governing body may assess the cost of the improvements against the property benefited in the manner provided by Kan. Stat. Ann. §§ 19-27a07 and issue general obligation bonds of the county in the manner provided by the general bond law in the amount necessary to provide the funds with which to make the necessary improvements.
