Water Tank Buyer’s Guide

Water tanks come in a huge range of types, sizes and materials; the article below briefly outlines some facts and tips.

water tank materials
When you choose a new water tank, you should look for one that is cost-effective yet of good quality and with a reasonably long service lifespan. Water tanks are used for storing drinking water, farming, irrigation purposes and more. Since drinking water can be susceptible to pH changes, algae, bacteria, viruses and chemical contaminants, water tanks isolate it from the outside world and store it safely until needed. The various types of tanks are as follows:

  • Chemical contact tanks are made of NSF and FDA polyethylene, allowing some retention time for chemicals, filtering out harmful substances in the process. They also allow more retention time for chemical treatments of the water inside.
  • Ground water tanks are often made of good, lined carbon steel and they receive their water intake from the surface or water wells. They can be used to store large amounts of water.
  • Water towers, also known as elevated water tanks can be a perfect solution in low water pressure areas. They work for a number of industrial and domestic needs across the board.
  • Vertical cylinder dome top tanks are a very simple, yet very useful design which allows one to hold anywhere from fifty to millions of gallons of water.
  • Hydro-pneumatic tanks are horizontal and pressurised, which allows for an easy delivery of water through a distribution system.

Water tanks also come in a wide range of materials, each with its own uses and benefits. The most common ones are as follows:

  • Polyethylene tanks are usually made of food grade material  if used for storing potable water. Poly water tanks are cost-effective and can last a long time, allowing a less expensive water tank solution compared to tanks made from other materials. Polyethylene water tanks can be recycled when they reach the end of their service life. Underground polyethylene water tanks are also available.
  • Collapsible pillow tanks as well as water bags are a cheap and useful alternative for industrial, commercial and residential needs. They are often made from heavy-duty fabrics.
  • Galvanised steel water tanks use hot dip galvanizing to coat the steel with zinc. It helps slow down corrosion and extend the life of the tank, but in most cases they rarely last past five years due to the process of electrolysis, which can be severe, depending on the quality of water and environmental conditions. Stainless steel water tanks are also available and these are less prone to corrosion but much more expensive.
  • Fiberglass tanks last a long time, with the added benefit of installation both below and above ground (NB only if rated for underground use). They are great at resisting corrosion and chemicals and lighter than most other materials (except for plastic tanks).  Fiberglass tanks tend to allow light in to the water and must be treated due to the danger of algae growth. Fibreglass tanks can become brittle and prone to cracking as they age.
  • Concrete water tanks can be built above ground or hidden underground, but they usually must be built on site due to their weight and bulk. The inner walls need to be properly sealed to prevent minerals from seeping into the water.
