WTE Ltd.Septic Tank - Sewage Treatment System - COSTS
Sewage Treatment Costs - There is a huge difference in the purchase prices and installation costs of different sewage systems as shown here. The cheapest sewage treatment plant in the UK is the VORTEX™:-
Cost of a CESSPOOL
Typical Costs for a single 3 bed house
- Tank Cost = £3500 (35,000 litres)
- Installation Cost = £6500
- TOTAL COST = £10,000
Typical Maintenance Costs (Emptying only is required)
- Average family of 4 persons x 200 litres per day = 800 litres per day volume discharged.
- Min. tank capacity = 18,000 litres Storage capacity = 18000 / 800 = 22.5 days
- Therefore tank will require emptying - 365 / 22.5 = 16.2 times per year
- With an average emptying cost of around £180 per4500 litres, a complete emptying of 18000 litres will cost £720, 16 times a year
-
Average annual cost = £11,520 per year
Cost of a SEPTIC TANK
Typical Costs for a single house
- Tank Cost = £790 (larger tanks cost more)
- Installation Cost = £1500
- Soakaway system (assuming 100 metres of drains) = £5200
- TOTAL COST = £7490.00
Typical Maintenance Costs
- Emptying once per year = £150 per year
-
Percentage cost of replacement soakaway (every 10 years average ) =£520
-
Average annual cost = £670.00
If a septic tank and land drainage system are unable to treat the sewage, then one of the following sewage treatment systems must be used to remove a substantial amount of the pollution contained in the wastewater and protect our environment.
Cost of a TRADITIONAL SEWAGE TREATMENT PLANT
Typical Costs for a single house
- Plant Cost = £1800 to £3200
- Installation Cost = £2000 to £3000+ (depending on the model.)
- Land drainage system (assuming 100 metres of drains) = £5200 or £200 typical cost if to a ditch with a 10 metre pipe run
- TOTAL COST = £4000 to £11,400+
Typical Maintenance Costs
- Emptying (either annually or 6 monthly, (depending on the model) £130 to £260 per year
- Power consumption = £80 to £180 per year (depending on the model)
- Maintenance Service = £75 to £375 (depending on unit chosen) per year
-
Average annual cost = £285 to £815 per year
Cost of a MODERN 'extended aeration' or 'activated sludge' SEWAGE TREATMENT PLANT

-
Plant Cost = £1460 to £2400
-
Installation cost = £600 to £3000
-
Drainage system to Ditch = £25.00/metre of drain run
-
TOTAL COST £2060 to £5400
Typical Maintenance Costs
- Emptying = £130.00/year
- Power consumption = £80 to £180 (depending on the model)
- Maintenance Service = £75 to £130 (depending on the model)
-
Average annual cost = £285.00 to £440.00 per year
Cost of a FILTER SEWAGE TREATMENT PLANT

- Power consumption = £0
-
Maintenance Service = £100.00
-
Average annual cost = £175.00 per year
Cost of REED BED sewage treatment
Typical Installation Costs
-
Septic tank installed price £2250
-
Total supply and Installation Cost = £ 8500 (including power supply etc.)
- Land drainage system (assuming 100 metres of drains) = £ 5200 (or this may be a reduced cost if using an outfall pipe to a stream if the reed bed is used as a tertiary treatment after a sewage treatment plant)
- TOTAL COST = £15,950 (Note - there may be a cost for the larger area of land required)
Typical Maintenance Costs
- Emptying of tank once per year = £180 per year
- Power consumption of the pumps = £290 per year
- Maintenance = reed harvesting/composting/replanting (4 days work) = £450
