Non-household sewerage tariffs Sewerage services comprise four main activities, which are for collecting and treating:
Charging for foul sewerage Companies usually base their charges for the foul sewerage service for metered non-household customers on the volumes recorded on the water meter (adjusted where appropriate for non-return to sewer allowances). Non-household metered customers' standing charges depend upon the size of their meter. Details of these charges are in this table. Most unmetered non-household customers pay for foul sewerage according to a charge based on the rateable value of their property. Large user tariffs for foul sewerage The principles that companies should apply when setting large user tariffs for water should also apply when they set large user tariffs for foul sewage or trade effluent. So, companies typically justify their large user tariffs for foul sewage or trade effluent on the basis that large customers make less use of the reception and conveyance part of the service. This table gives details of companies' large user sewerage tariffs. Charging for surface water drainage and highway drainage Historically, companies have charged non-domestic customers for surface water and highway drainage services in a variety of ways, including:
Trade effluent Businesses must have the consent of their sewerage company before discharging trade effluent into public sewers. According to the Water Industry Act 1991, 'trade effluent' means any liquid which is wholly or partly produced in the course of any trade or industry carried on at trade premises, but does not include domestic sewerage. The costs of collecting, treating and disposing of trade effluent depend upon the amount and strength of the wastewater. However, unlike foul sewerage, companies assess for charging purposes the strength and volume of trade effluent before it enters the sewers. Charges for trade effluent are based on the Mogden formula, which is given below. Charge per unit of effluent = R +[(V + Bv) or M] + B(Ot/Os) + S(St/Ss) This table shows details of companies' trade effluent tariffs and definitions for the Mogden formula. This formula links charges to the characteristics (volume and strength) of the discharges from a customer's premises, which determine the level of treatment needed and therefore the costs involved. Companies calculate the average costs across their regions, so charges do not reflect the costs incurred at any one treatment works. Companies may reduce the collection charge if a discharger is connected directly to the treatment works.  |
