EXECUTIVE SUMMARY

This report examines the Scottish Water Industry, providing coverage of water supply and sewerage services provided by the three authorities, EOSWA, NOSWA and WOSWA.

The capital expenditure on water supply and sewerage related projects by each of the authorities for the 1992/93 to 1996/97 financial period and forecast expenditure for the 1997/98 to 2001/02 period.

For the purposes of this report, sewage refers to water-borne wastes from domestic uses of water, derived from households or similar uses in trade and industry.

Sewage sludge is a by-product arising from the treatment of sewage or from septic tanks or similar installations.

Sewerage is a system of pipes and mechanical appliances for the collection and transportation of domestic and industrial waste waters.

With regard to sewage, treatment levels are classified as follows:

Preliminary treatment: gross solids in sewage are removed or disintegrated by passing it through screens

Primary treatment: sewage flows into settling tanks where solid material sinks to the bottom.

Secondary treatment: relies on the action of natural bacteria to break down the organic matter that is left in the sewage after primary settlement.

Tertiary treatment: the removal of suspended matter and nutrients to enable the effluent to comply with more stringent standards before discharge to a receiving water.

The purpose of the PFI is to use private sector finance and management expertise for projects which would traditionally have been financed and operated by the public sector.
