Whenever a person installs sewers or other facilities for sewers and the district board determines that it is necessary that such sewers or other facilities be constructed so that they can be or will be used for the benefit of property other than that of the person making the installation and such sewers or other facilities are dedicated to the public or become the property of the district, the district board may by contract agree to reimburse such person for such sewers or other facilities. Such contract may provide that the district may collect from any person using such sewer or other facility for the benefit of property not owned by the person making the installation a reasonable fee or charge.
