General terms & Conditions
In order to carry out water tank cleaning works, the following will be required:
Unrestricted parking adjacent to the building
Unrestricted access to the water storage tank during normal working hours.
Lighting and 240/110v power supply within 10m of the water storage tank
The identification of a foul drain suitable for the discharge of the volume of water contained within the tanks.
Any quotation for water tank cleaning is provided based on the assumption that the tank and all pipework, isolation valves, float valves and other equipment related to the tank are in good working condition and durable enough for the work to take place. Where isolation valves are not functioning correctly it may not be possible to isolate the tank in order to carry out the work. Where tanks are in poor condition it is not unusual for failure of the tank to occur on re-filling. No allowance has been made for the repair or replacement of any mechanical items which might allow the tank to function correctly and no liability of any kind will be accepted by Purewater Environmental Services Ltd for damage or loss to any materials, items or injury or loss to any persons.
If engineers attend site & the works cannot take place for reasons which are beyond our control an aborted site visit charge will be incurred.
Our public & product liability insurance cover is to a maximum of £2,000,000. Insurance cover in excess of this amount can be arranged if required, and will be charged for.
Purewater Environmental Services Ltd accept no responsibility for damage caused by leakage from damaged or unserviceable tanks, tank connections and pipework, drains, overflows or bunded areas or drain facilities which prove incapable of discharging or accepting the volume of water pumped from the tank(s) via a submersible pump (maximum bore 50mm).
Important legislative requirements
It is also a requirement of the HSE (Health and Safety Executive) that a Legionella risk assessment is carried out to assess the risk associated with water systems with a clear written procedure for minimising the risk and implementing management schemes to provide on-going management control.
The Health & Safety Commission document L8 "Legionnaires' Disease – The Control of Legionella Bacteria in Water Systems, Approved Code of Practice & Guidance", gives practical guidance with respect to Sections 2, 3, 4 and 6 of the Health & Safety at Works Act 1974 and Regulations 9 and 12 of the Control of Substances Hazardous to Health Regulations 1999. The code of practice came into effect on 8th January 2001 and supersedes HSE document HS(G)70/L8 Rev "The Prevention or Control of Legionellosis (including Legionnaires Disease)".
To comply with their legal duties, employers and those with responsibilities for the control of premises should:
- Identify and assess the source of risk.
- Prepare a scheme for preventing or controlling the risk.
- Implement, manage and monitor precautions: and
- Appoint a person to be managerially responsible.
Any risk assessment must be reviewed whenever there is a reason to believe that the original assessment may no longer be valid. This may be necessary due to any of the following:
- Changes to the plant or water system(s) or its use.
- Changes to the use of the building itself.
- The availability of new information relating to the control of any risk.
- As a result of checks indicating that control measures are no longer effective.
- A case of Legionnaires’ Disease/Legionellosis being associated with the system.
- The control scheme should be reviewed every two years.
