Sectional Water Tanks Sizes – Up to 1.3 Million Litres

(For larger volumes of water storage please talk to our team of experts)

Dewey Waters employs two moulding techniques Single Face Contact Moulding (SFCM) and Hot Press Moulding (HPM) to manufacture the sectional panels. The method employed depends on individual site requirements and which technique provides the most economical solution for our clients. Both techniques adhere to current British Standards, and are covered by our quality control procedures.

Sectional tanks are supplied in the following formats:

  • Internally flanged base – Externally flanged sides: This tank is suitable for installation on a fully supporting flat base
  • Externally flanged base – Externally flanged sides: This type of base allows easy access to bolts for maintenance and tank may be fully drained.
  • Internally flanged base – Internally flanged sides: This tank is used where the space available is restricted.
