Objectives

The primary objective of this tender is to establish a 12-month contract for water treatment services at St Marys Marianhill Hospital. The contract aims to ensure the hospital's water systems—including cooling systems, boilers, and domestic water tanks—are effectively treated to meet health and safety standards, prevent scale and corrosion, control biological fouling, and comply with IPC protocols. Additionally, the contract seeks to provide ongoing maintenance, chemical supply, equipment servicing, and comprehensive analysis to support optimal water system performance and safety.

Scope

The scope of the tender encompasses:

• Provision of water treatment chemicals for cooling towers, boilers, and domestic water storage tanks.
• Adjustment, servicing, and maintenance of existing water treatment equipment at no extra cost.
• Monthly site visits for chemical dosing, system analysis, and reporting.
• Control of scale, corrosion, and biological fouling, including Legionella prevention.
• Water analysis for parameters such as pH, TDS, residuals, hardness, and microbiological testing (e.g., E-Coli, Legionella).
• Handling all chemical applications and equipment adjustments by the service provider, with no chemical handling by hospital staff.
• Specific treatment for domestic water tanks, maintaining a free chlorine residual of 1ppm, with biannual microbiological testing.
• Provision of warranty for any system scaling or damage resulting from chemical supply or application failures.

Technical Requirements

The technical requirements for the tender include:

1. Chemical Supply: Supply of chemicals for:
• Cooling towers: scale and corrosion control, biological fouling biocides (alternating biocides, including one targeting Legionella).
• Boilers: organic-based chemicals for scale and corrosion prevention, including coarse salt for water softening.
• Domestic water tanks: chemicals to maintain a free chlorine residual of 1ppm, with microbiological testing.
2. Equipment Maintenance: Adjustment, servicing, and maintenance of existing water treatment equipment during monthly visits.
3. Monitoring & Analysis: Regular on-site chemical analysis and comprehensive reporting on parameters such as pH, TDS, residuals, hardness, and microbiological presence.
4. Biocidal Program: Use of alternating biocides to prevent resistant strains, with specific targeting of Legionella Pneumophila.
5. Service Visits: Monthly on-site visits for chemical dosing, system checks, and equipment adjustments, with detailed reports provided after each visit.
6. Water Quality Testing: Biannual microbiological testing for E-Coli, Legionella, Total Coliforms, and other relevant parameters.
7. Documentation & Reporting: Submission of detailed reports on water analysis, system condition, and any corrective actions taken.
8. Warranty & Responsibility: The supplier must warrant that any scaling or system damage due to chemical application failures will be rectified at their expense.
9. Compliance: All treatment processes must adhere to IPC protocols and relevant health standards.
