Cold Water Storage Tank FAQs
What are Water Storage Tanks made of?
All of our water storage tanks are manufactured from Glass Reinforced Plastic (GRP). It is also called fibreglass, composite plastic or FRP. It is strong, extremely light and highly versatile. GRP behaves differently to the conventional thermoplastics that are used in everyday items. Other tank manufacturers may use mild steel pressed panels, stainless steel, and polyethylene.
How to size a water tank?
BS EN 806-2:2005 19.1.4 offers the following guidance on water storage tank capacities:
Table 6 gives recommendations for storage capacities related to various types of use but these are to be regarded as a guide only.
In determining the total capacity of cold-water storage in the premises concerned, account shall be taken of:
- a) the need to prevent stagnation by ensuring that water is held in storage for as short time as possible; and
- b) the requirements of any associated water fittings and appliances, particularly where supply interruptions can cause damage to property or inconvenience to the user.
Table 6 – Recommended minimum storage of cold water for domestic purposes (hot and cold outlets)
|Type of Building or Occupation||Minimum Storage in Litres (L)|
|Hostel||90 per bed space|
|Hotel||200 per bed space|
|Restaurant||7 per meal|
|Boarding School||90 per pupil|
|Children’s Home or Residential Nursery||135 per bed space|
|Nurse’s Home||120 per bed space|
|Nursing or convalescent home||135 per bed space|
The water supplier should be consulted before finalising cistern capacity to hotels, hostels, office premises (with or without canteen facilities), schools (day and boarding) and other substantial establishments.
For most dwellings where a constant supply at adequate pressure is a statutory requirement, a maximum capacity of 80 l per person normally resident should prove satisfactory. A larger capacity based on 130 l per person would be appropriate where cistern refilling normally takes place only during the night hours.
How often should cold water storage tanks be cleaned?
Cold water storage tanks should be inspected, and any remedial works carried out on an annual basis as stipulated in HSG274 Part 2. Additional guidance & instruction is provided in BS8558 & the HSE approved Code of practice & guidance (ACOP) book L8 entitled ‘Legionnaires’ disease. The control of legionella bacteria in water systems’.
