Comparison of Sewage Treatment Costs

Posted on 23 Nov 2012 by Biorock

Sewage Treatment Costs - There is a huge difference in the purchase prices and installation costs of different sewage systems as shown here. Compare the costs and see yourself the economic advantages of BIOROCK!

Costs of a BIOROCK-5 system

Typical costs for a single house

  • PrimaryTank + Bioreactor Costs = around £3,400
  • Installation Cost = contact us for our installers list.
  • Operational Costs (electricity) = £0
  • TOTAL COST = around £3,400 + installation, and that's all !

Typical Maintenance Costs

  • Average family of 4 persons x 150 litres per day = 600 litres per day volume discharged.
  • Tank capacity = 3,300 litres storage capacity
  • Tank requires only 1x per year emptying (environmantal agency requirement)
  • With an average emptying cost of around £180 per 4,500 litres, an emptying of max. 1,500 litres (50% charging level) will cost £60
  • AVERAGE ANNUAL COSTS (first year) = £6,460 per year
  • AVERAGE ANNUAL COSTS (following years) = £60 per year

Costs of other systems

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 per 4500 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 a BIOROCK sewage treatment system 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 an 'extended aeration' or 'activate sludge' sewage treatment plant

Typical Costs for a single house

  • Plant Cost = £1520 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

Typical Costs for a single house start at

  • Plant Cost = £3000
  • Installation cost = £2000 to £4000
  • Drainage system to Ditch = £20.00/metre of drain run
  • TOTAL COST £5000 to £7000

Typical Maintenance Costs

  • Emptying once every 2 years = £75.00/year
  • Power consumption = £0
  • Maintenance Service = £100.00
  • Average annual cost = £175.00 per year

Cost of reed bed sewage treatment plant

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
  • Total reedbed replacement required every 10 years (Aston University Research for Severn Trent Water Authority)
  • TOTAL COST = £2515 per year
