Scottish Water has gone out to tender with a framework contract for water treatment chemicals worth an estimated £108 million.

The successful supplier will be required to deliver chemicals to site locations within Scottish Water’s operational areas. The water company’s requirement will cover water treatment and wastewater treatment for a number of purposes including; coagulation, flocculation, PH adjustment, disinfectant, odour control, ammonia reduction and plumbosolvency management.

The chemicals must be supplied in 1 000 L IBC’s, pressure bins, drums, bulk deliveries or packed goods. Chemicals required through the framework include: ammonium sulphate, caustic soda, hydrochloric acid, phosphoric acid, mono sodium phosphate, poly-aluminium chloride, sodium carbonate, sodium hypochlorite, sulphuric acid, citric acid, sodium bisulphite, polyelectrolytes, ferric sulphate, osec salt, aluminium sulphate and odour control chemicals.

Scottish Water said it would look to optimise the number of suppliers to give best value but will consider appointing a single source supplier if deemed best value. Where possible, the framework will include at least 2 suppliers capable of supplying each chemical, even if one of the suppliers is not routinely used.

Initial contract term is four years with a further 4-year extension option.
