Thames Water tenders £74.76m water treatment chemicals contract

Thames Water has today gone out to tender with a major contract for water treatment chemicals worth an estimated £74.76 million in total.

The water company is looking to put a framework agreement in place for the supply and delivery of a wide range of chemicals that are used in their clean water production and waste water treatment processes. The chemical portfolio in scope includes inorganic chemicals, and iron salts and aluminium salts.

The contract is being tendered in three separate Lots.

Chemicals covered under Lot 1 for the supply and delivery of bulk and packaged inorganic chemicals include:

  • Ammonium Sulphate
  • Caustic Soda Formic Acid
  • Hydrochloric Acid
  • Hydrogen Peroxide
  • Magnesium Sulphate
  • Nitric Acid
  • Pure Dried Vacuum Salt
  • Salt Pebbles – Aquasol
  • Sodium Bisulphite
  • Sodium Chlorite
  • Sodium Hypochlorite and Sulphuric Acid
  • Citric Acid
  • De-Ionised Water and Nitric Acid

Lot 2 for the supply and delivery of iron salts includes ferric sulphate, ferric chloride, ferrous sulphate and ferrous choride, while Lot 3 for aluminium salts covers poly aluminium chloride (PAC) 10%/18% and aluminium ferric sulphate.

The range of chemicals will need to be supplied and delivered in a variety of delivery methods, including bulk deliveries via bulk road tanker and packaged deliveries via intermediate bulk containers (IBCs)

Thames Water is reserving the right to award the contract via a number of options, including splitting lots by regional demarcation, by strategic sites and satellite sites, waste sites, clean sites or for a combination of both waste and clean sites.

During the agreement the company may also look to explore and introduce and adopt an inventory management service model for the management of their chemical portfolio. Suppliers will therefore need to be able to demonstrate that they have the experience and the capability to facilitate an autonomous chemical management process.

Thames Water is looking to improve the overall cost effectiveness and operation of its water production and waste treatment processes via the contract. The company has a number of objectives to target linked to chemical supply including:

  • optimisation of chemical usage
  • alternative chemistry trials
  • identification and delivery of service efficiencies
  • increasing green credentials
  • improving recycling and management of residual chemicals and waste products (including packaging and containers)

Contracts awarded under the framework agreement will run for an initial term of 5 years with options to extend the agreement up to a further 3 years.
