This district extends along Lake Michigan from the 

 north to the sonth liiie of Lake County. The proceedings 

 for the establisliment of the district were practically the 

 same as those by which the Sanitary District of Chicago 

 was formed. Three hundred instead of five thousand 

 petitioners were necessary to bring the matter up for 

 election. Bond issues with indebtedness not to exceed 

 in amount five per centum of the value of taxable prop- 

 erty within the district are provided for and taxes can be 

 levied not to exceed in any year one third on one per 

 centum of the value of taxable property within the dis- 

 trict limits. 



The board of trustees has power to provide for the 

 disposal of sewage and to preserve the water supplied 

 to the inhabitants from contamination and for that pur- 

 pose may construct and maintain conduits, pipes, chan- 

 nels, drains and outlets. It must pro^^ide suitable and 

 modernly ec^uipped sewage disposal works or plants for 

 the separation and disposal of all solids and deleterious 

 matter from the liquids, and must treat and purify the 

 residue of such sewage so that when it flows into any lake 

 it will not injuriously contaminate the water. The board 

 has power to enter into contract with any city or village 

 for the reduction, treatment and disposal of any garbage 

 or offal, or solid matter removed from sewage at any 

 disposal plant or treatment works. 



The district has acquired 30 acres of land for the lo- 

 cation of a purification plant, has investigated methods 

 of sewage treatment, and has raised money which is 

 available for construction.
