COMMITTEE ON PROCUREMENT
Mr. John P. Murray, Executive Director
Title
Issue purchase order and enter into an agreement with Envea Inc. to furnish and deliver Cairsens Cairpol Hydrogen Sulfide replacement sensors and Caircloud data management, in an amount not to exceed $119,330.00, Accounts 101-16000-612820, 623570, Requisition 1648991
Body
Dear Sir:
Authorization is requested to issue a purchase order and enter into an agreement with Envea Inc. (Envea) to furnish and deliver Cairsens Cairpol Hydrogen Sulfide (H2S)/Methyl Mercaptan (CH4S) replacement sensors and Caircloud data management for 2026, with the subsequent replacement sensors and cloud service for 2027 and 2028, which allow the system to remain in continuous operation until December 31, 2028. This purchase order will expire on December 31, 2028.
H2S/CH4S is an indicator of odor that can be measured to very low levels. Currently, the District has 27 Cairsens Cairpol H2S/CH4S monitoring systems deployed at the Stickney, Calumet, and North Side service areas. The replacement sensors and data management service will allow the District to continue monitoring H2S/CH4S at the existing sites. The District has also customized the H2S/CH4S monitoring backend telemetry system to better suit the District’s needs with respect to gathering the data and has developed an app that provides secure real-time H2S and weather data to augment plant operations. This purchase order will include purchasing replacement sensors for the existing monitoring systems and continuing Claircloud data management.
Envea, the sole service provider of Cairsens Cairpol H2S/CH4S sensor products and Caircloud data management has submitted pricing for the equipment and services required. Inasmuch as Envea is the only source of supply for the equipment and services required, nothing would be gained by advertising for bids (Section 11.4 of the Purchasing Act).
Envea Inc. is registered and in good standing with the State of Illinois.
The Multi-Project Labor Agreement (MPLA) is not applicable because the classification of work does not fall under the provision of the MPLA.
The Affirmative Action Ordinance is not included because Envea is the sole provider of the equipment and services.
In view of the foregoing, it is recommended that the Director of Procurement and Materials Management be authorized to issue a purchase order and enter into an agreement with Envea, in an amount not to exceed $119,330.00.
Funds for the 2026 expenditure, in the amount of $38,232.00, are available in Accounts 101-16000-612820, 623570. The estimated expenditures for 2027 and 2028 are $39,973.00, and $41,125.00, respectively, and are contingent on the Board of Commissioners’ approval of the District’s budget for those years.
Requested, Edward W. Podczerwinski, Director of Monitoring and Research, EWP:RA:JSG:JV:jb
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Precious Brady-Davis, Chairperson Committee on Procurement
Disposition of this agenda item will be documented in the official Regular Board Meeting Minutes of the Board of Commissioners for January 22, 2026
