The Federal Bureau of Prisons is conducting market research for comprehensive cooling-tower and closed-loop water-treatment services at FCI Three Rivers in Three Rivers, Texas. The work includes chemical treatment, testing, maintenance, filter changes, and emergency response for the facility's water systems. The government anticipates a firm-fixed-price contract with one base year and four one-year option periods. Service requirements include routine response within 24 hours and on-site response within eight hours for critical emergencies. This is a sources-sought notice for planning purposes only and does not obligate the government to issue a solicitation or award a contract.
