    Greenbank Group logo

    Greenbank Group

    United Kingdom

    A specialist engineering company with a global customer base. Greenbank provides a wide range of products and services to companies operating across a number of industries and is now establishing itself in the clean and wastewater sector. For many years the company has utilised the unique properties of volcanic basalt for lining products used in heavy industries such as power generation and minerals extraction. In partnership with Czech firm Eutit, the company has also been pioneering the use of basalt in the renovation and restoration of sewer systems in central European following a series of successful projects in Prague. As a result of devastating floods, the city’s sewer system was extensively rebuilt and upgraded with basalt being used in a number of key locations to provide a new level of security to the system. More than a decade on, the new system continues to perform well and has set a standard that’s now been followed in other European cities. Well suited for the most demanding of applications, thanks to the partnership between Greenbank and Eutit, a wide range of basalt solutions are now available in the UK market. These include products and systems that bring a wide range of benefits to the industry, including: Basalt tiles that can also be used to line existing brickwork, a more cost-effective solution than full replacement, and their reduced drag co-efficient means improved flow – in effect a smaller-diameter pipe or tunnel lined with basalt can carry a higher volume of water than a larger one with traditional brick surfaces. The effective life expectancy of basalt-lined sewer systems is between 100 and 200 years, thanks to their excellent resistance to abrasion and chemical damage – as well as the rigours of high-pressure water jetting that’s often used to clear unwanted blockages. For larger round or ovoid systems, basalt can be used in the lower sections to deal with the wear and tear with concrete upper sections to provide optimum life performance. Alternatively, steel pipes lined with basalt can be produced up to 3000mm diameter producing a lighter therefore lower cost installation option to thick wall concrete. Ease of installation and reduced maintenance costs make basalt ideal for bottom gutters, branch pipes and tubes and slip-resistant elements for walkways, and Greenbank can also supply bespoke-shaped tiles to meet the unique requirements of individual clients. With manufacturing facilities in Derbyshire and Nottinghamshire, supported by the additional capacity and expertise provided by the latest addition to the group, Franklyn Yates Engineering, Greenbank is well placed to react quickly and efficiently to the needs of new and existing clients.

    Energy-Efficient Devices and Systems for Water Operations

    Energy consumption typically represents 25 to 40 percent of a water or wastewater utility operating cost: pumping accounts for 60 to 80 percent of that, aeration in activated-sludge plants 50 to 60 percent of plant electrical load. Energy-efficiency interventions target the dominant loads: high-efficiency premium IE4/IE5 motors (per IEC 60034-30-1), variable-frequency drives matching pump curves to dynamic demand, fine-bubble aeration replacing coarse-bubble diffusers (oxygen-transfer efficiency 25 to 35 percent vs 8 to 12 percent), turbocharged blowers replacing positive-displacement (15 to 25 percent energy savings), pressure management on distribution networks (every 1 bar reduction saves about 1 percent energy and 5 to 10 percent leakage), and energy recovery devices on RO trains (PX rotary recovery over 97 percent efficient).

    Sector benchmarks (kWh per m3): conventional drinking-water treatment 0.3 to 0.5; brackish-water RO 0.8 to 1.5; seawater RO 3.0 to 4.5; conventional ASP wastewater 0.4 to 0.7; MBR wastewater 0.8 to 1.5; large-scale anaerobic digestion is net-energy-positive at biogas yields above 0.3 m3 CH4 per kg VS destroyed. ISO 50001 energy-management certification provides the audit framework; ENERGY STAR Portfolio Manager benchmarks plant performance against peers. Typical energy-audit findings reveal 15 to 30 percent achievable savings without major capex, payback typically 2 to 5 years. Renewable integration (solar PV, biogas-to-power, micro-hydro on transmission pipelines) is increasingly cost-competitive at utility scale.

    Aguato lists energy-efficiency providers across premium motors, VFDs, high-efficiency pumps, fine-bubble aeration, turbocompressor blowers, energy recovery devices, pressure-management valves, and solar PV and biogas CHP integrators. Selection criteria: measured kWh-savings guarantees backed by ISO 50001 M&V protocols, performance bonds tied to verified savings, third-party utility-program rebate eligibility (US: utility DSM programs; EU: Energy Efficiency Directive 2023/1791 Article 8 audits), and 24-month operational data from comparable installations.

    Frequently Asked Questions

    What is the fastest-payback energy-efficiency upgrade for a wastewater plant?

    For conventional ASP plants, replacing coarse-bubble diffusers with fine-bubble membrane diffusers plus automated DO control with VFD-driven blowers typically returns 25 to 40 percent aeration energy savings (15 to 25 percent plant total) with 1.5 to 3 year payback. For lift stations and high-service pumping, VFD retrofits on constant-speed pumps with variable demand returns 10 to 25 percent savings, payback 1 to 3 years. For RO desalination, retrofit of pressure exchangers on legacy Pelton-wheel or no-recovery systems delivers 25 to 40 percent specific energy reduction, payback 2 to 4 years depending on electricity tariff.

    What efficiency class motor should I specify?

    IEC 60034-30-1 defines efficiency classes IE1 (standard) through IE5 (ultra-premium). The EU MEPS (Minimum Energy Performance Standards) Regulation 2019/1781 requires IE3 minimum for motors 0.75 to 1,000 kW since 2021, with IE4 required for 75 to 200 kW since 2023. US DOE has equivalent NEMA Premium standards. For variable-speed service (with VFD), specify inverter-duty IE4 with insulation class F and Class B temperature rise per NEMA MG-1 Part 31. Lifecycle cost: an IE4 motor costs 10 to 25 percent more than IE3 but saves 2 to 4 percent energy: payback typically under 2 years at over 4,000 annual run hours.

    How much energy can pressure management save on a distribution network?

    Empirical rule from IWA Pressure Management literature: every 1-bar reduction in average network pressure reduces leakage by 5 to 15 percent (FAVAD N1 exponent typically 1.0 to 1.5 for mixed pipe materials) and reduces burst frequency by 20 to 40 percent. Energy savings track the leakage reduction plus the pumping head reduction at the source: typically 10 to 25 percent pumping-energy savings on networks moving from constant-pressure to dynamic pressure control via PRVs with flow-modulated setpoints. Payback for a PRV plus telemetry retrofit on a 5,000-connection DMA is typically 2 to 4 years.

    Are utilities eligible for grid incentives for energy efficiency?

    Yes, in most major markets. US: utility DSM (demand-side management) programs offer rebates of 0.05 to 0.20 USD per kWh saved annually for prescriptive measures (motors, VFDs, lighting) and custom incentive payments up to 0.30 USD per kWh for engineered projects (aeration optimization, pump curve matching). EU: Energy Efficiency Directive 2023/1791 obligates large enterprises (1,000-plus TOE per yr or 10M EUR turnover) to implement audits and energy-management systems; member-state white-certificate schemes (Italy TEE, France CEE) pay 5 to 15 EUR per MWh of certified savings. Always model project economics with and without incentives: incentives typically reduce simple payback by 30 to 50 percent.

    Case Study·Municipal wastewater treatment
    Challenge

    A 200,000 PE activated sludge plant in the North West England operated on fixed-speed positive-displacement blowers with constant-pressure aeration. Electricity accounted for 62 percent of site OPEX, with aeration representing 55 percent of that. An Ofwat AMP8 totex efficiency commitment required a 15 percent energy reduction by 2030.

    Approach

    Replaced three fixed-speed PD blowers with two turbo blowers (oil-free, VFD-driven, IE4 motors) sized for 30 to 100 percent of design airflow. Installed online ammonia and DO sensors at three points in the aeration lanes, linked to a dissolved-oxygen control algorithm with automated modulating inlet guide vanes on each blower. Replaced coarse-bubble diffusers with fine-bubble membrane disc diffusers increasing SOTE from 9 percent to 28 percent.

    Outcome

    Aeration energy fell 38 percent (from 3.2 to 1.98 kWh per kg BOD removed). Site total electricity consumption fell 22 percent. Capital cost of 1.85M GBP recovered in 3.1 years at 0.18 GBP per kWh. Ofwat totex efficiency commitment exceeded. Effluent quality improved (ammonia 95th percentile reduced from 3.2 to 1.1 mg/L) due to tighter DO control.

    Questions to Ask Shortlisted Providers

    1. 1

      What measured specific energy consumption (kWh per m3 or kWh per kg BOD removed) does your equipment achieve in comparable UK reference plants, and can I visit one?

      Manufacturer efficiency claims are made under ideal test conditions. Field-verified data from a comparable UK plant (same technology, similar loading, similar tariff) is the only reliable basis for financial modelling. A supplier who cannot provide a site visit reference should be treated with caution.

    2. 2

      What IEC efficiency class is the motor, and is it inverter-duty rated for VFD operation?

      UK MEPS (Minimum Energy Performance Standards, SI 2021/745 implementing EU 2019/1781) requires IE3 minimum from July 2021 and IE4 for 75 to 200 kW from July 2023. Motors driven by VFDs are subject to additional voltage stress and must be inverter-duty rated per NEMA MG-1 Part 31 or IEC 60034-17 to prevent premature insulation failure.

    3. 3

      What ISO 50001 measurement and verification protocol will you use to demonstrate guaranteed energy savings?

      Energy savings guarantees without an agreed M&V protocol are unenforceable. ISO 50001 IPMVP Option A (stipulated measurements) or Option B (all parameter measurement) should be agreed before contract signature, specifying baseline conditions, measurement boundary, and independent verification process.

    4. 4

      Are your turbo blowers or VFDs eligible for UK utility DSM rebate schemes, and will you support the rebate application?

      UK water utility energy efficiency projects may attract ESOS (Energy Savings Opportunity Scheme) compliance credit and some regional electricity network company DSM rebates. Supplier support for the rebate application can recover 5 to 15 percent of project CAPEX. Confirm eligibility and the application process before award.

    5. 5

      What is the noise output at 1 metre and at the site boundary, and have you modelled compliance with BS 4142:2014 for the nearest noise-sensitive receptor?

      Turbo blowers and new diffuser systems change the acoustic profile of a WWTP. Control of Noise at Work Regulations 2005 apply to operator exposure; BS 4142:2014 governs community noise impact. Planning conditions on many WWTPs include site-boundary noise limits. A noise assessment before purchase avoids post-installation noise enforcement from the local authority.

    What Drives Cost in This Category

    Motor efficiency class upgrade

    Upgrading from IE2 to IE4 motors on a 100 kW pump running 8,000 h/year at 0.18 GBP per kWh saves approximately 4,000 to 6,000 GBP per year. IE4 motor premium over IE2 is typically 3,000 to 8,000 GBP: payback 1 to 2 years. This is the highest return-per-pound energy efficiency measure in water operations.

    VFD retrofit on constant-speed pumps

    VFD retrofit on a 75 kW pump with 30 percent part-load duty saves 20 to 30 percent energy (cube law applies where flow variation is accommodated by speed reduction). Installed cost 5,000 to 15,000 GBP including motor protection filters. Payback 1.5 to 3 years at UK industrial tariffs.

    Fine-bubble aeration diffuser replacement

    Replacing coarse-bubble diffusers with fine-bubble membrane disc diffusers increases standard oxygen transfer efficiency (SOTE) from 8 to 12 percent to 25 to 35 percent per metre of submergence. Capital cost 50,000 to 250,000 GBP for a 50,000 PE plant. Energy savings 25 to 40 percent of aeration cost. Payback 2 to 4 years.

    Online DO and ammonia control instrumentation

    Online dissolved oxygen and ammonia sensors enabling cascade aeration control cost 15,000 to 40,000 GBP installed per lane but unlock 10 to 20 percent additional energy savings beyond hardware upgrades alone by precisely matching airflow to biological demand. Without control optimisation, fine-bubble diffusers and turbo blowers often run at over-aeration setpoints.

    Key Regulations & Standards

    UK MEPS -- IE3/IE4 Motor Efficiency Requirements

    The Ecodesign for Energy-Related Products and Energy Information Regulations 2021 (SI 2021/745) implement EU Regulation 2019/1781 in UK law, requiring IE3 minimum efficiency for motors 0.75 to 1,000 kW from July 2021. IE4 is mandatory for 75 to 200 kW motors from July 2023. Non-compliant motors cannot be placed on the UK market. Water utility procurement must specify at minimum IE3 for all motor replacements.

    ESOS (Energy Savings Opportunity Scheme) Phase 3

    Large water companies (turnover above 43M EUR or 250-plus employees) must comply with ESOS Phase 3 (compliance deadline December 2023). ESOS requires a qualified lead assessor to audit at least 90 percent of energy consumption and identify cost-effective energy-saving opportunities. Identified measures (including pump, blower, and aeration upgrades) must be documented and submitted to the Environment Agency. Non-compliance penalties up to 50,000 GBP.

    Environmental Permitting Regulations 2016 -- Energy Performance Conditions

    Environmental Permits for large wastewater treatment works increasingly include energy performance conditions aligned with BAT under the Industrial Emissions Directive (retained in UK law). BAT-AELs for energy consumption (kWh per m3 treated) set reference benchmarks. Permits require reporting of annual energy consumption and specific energy per m3, creating accountability for energy efficiency performance.

    Ofwat AMP8 Totex Efficiency -- Energy as Regulated Cost

    Ofwat's PR24 Final Determination sets totex efficiency challenges for water companies in AMP8 (2025 to 2030). Energy efficiency investments are assessed as totex: efficient investments qualify for inclusion in the regulatory asset base. Ofwat expects water companies to demonstrate energy-efficiency improvement trajectories and may disallow inefficient energy spend from the allowed revenue base. Companies must report energy consumption per unit of output in their annual performance report.
