Okla. Stat. tit. 11, § 11-37-206: Establishment of district sewer and water distribution

lines - Petition.

District sewers and district water distribution lines shall be

established within the limits of the districts, to be prescribed by

ordinance. District sewers shall connect with public sewers or

other district sewers, or with the natural course of drainage, as

each case may be. District water distribution lines in contiguous

or noncontiguous areas may connect with public distribution lines,

or other district distribution lines. The governing body shall

cause sewers and/or district water distribution lines to be

constructed in each district whenever the record owners of more than

one-half the area of land liable to assessments for the improvement

shall petition therefor. The petition shall be filed with the city

clerk. The petition shall state in bold, capitalized letters at the

top of the page that the cost of the proposed improvements shall be

assessed against the property benefited by the improvements. The

districts may include mains and submains where the same are within

the limits of the district or are necessary outlets or supply lines

thereto.
