This is a combined synopsis/solicitation for commercial products or services, and it constitutes the only solicitation; offers are being requested without a separate written solicitation. It covers the provision of chemicals and incidental services for Water Treatment Plants and Waste Water Treatment Plants at the Public Works Department, Sigonella, as detailed in the Statement of Work. The acquisition is not set aside for small business concerns, and applicable provisions and clauses are incorporated by reference via www.acquisition.gov. The government intends to respond to questions with a posted Q&A rather than issuing an amendment, unless a required change to the solicitation is necessary.
