"drainage and sewage pumps"

Severn Trent Water Asset Creation was tasked with constructing a new sewage pumping station to replace an existing asset that had reached the end of its working life.

2020 General Binding RulesFor decades, millions of septic tanks have been installed throughout the UK in rural and urban areas. Septic tanks are known to be ineffective at processing sewage to modern environmental standards, causing long-term damage to the country’s natural water infrastructure and wildlife.It was therefore inevitable that new rules and a code of conduct would be introduced to prevent the effects of wastewater pollution once and for all; The Environmental Permitting (England and Wales) (Amendment) (England) Regulations 2014 came into force on 1 January 2015 creating the General Binding Rules (GBRs) for septic tanks or small sewage treatment plants for domestic use. These rules are designed to reduce the level of pollution from sewage in the nation’s watercourses.The rules state that any existing septic tank discharging to surface water, ie, to a water ditch, stream or river, etc, must have been upgraded or replaced with a new package sewage treatment plant by 1st January 2020.  Failure to comply can incur significant fines from the Environment agency and delays in selling impacted properties.OptionsCurrent methods of discharging wastewater from septic tanksPrevious to the General Binding Rules, wastewater from septic tanks was typically discharged in the following two ways:Drainage fieldWastewater is released through a network of pipes in surrounding sub-soils, providing an additional form of treatment for the waste from the septic tank. This helps to ensure that the wastewater being dispersed does not cause pollution.Septic tanks discharging into a drainage field are not affected by the 2020 septic tank regulations.Directly to surface waterWastewater flows through a pipe directly into a stream, river or lake. Binding rules state that direct discharge from a septic tank into a watercourse is not permitted.So, what are your options?1. Connect to the main sewerThis may not be possible in remote locations, although pump chambers can be used to direct wastewater to the mains sewer.2. Install a drainage field(Designed in accordance with BS6297)This allows the septic tank to discharge wastewater into the ground instead of surface water. In many cases, the installation of a drainage field is not possible due to site constraints such as space and/or the soil not having sufficient drainage potential (ie, rock, clay, high water table).3. Install a Uni:Gem septic conversion unitA Marsh Uni:Gem can be installed and connected to a pre-existing septic tank. This treats the wastewater to a sufficient quality allowing it to be discharged to surface water. See below for further detail.4. Upgrade your septic tank to a Marsh sewage treatment plantThis eliminates the need for a drainage field and ensures that the wastewater is fully treated before being discharged. Options include the Ensign, Ensign Shallow and Ultra Poylok L.Uni:Gem★Marsh Industries, the leading UK manufacturer of package sewage treatment plants, produces over 3000 units per year. However the company’s range of Uni:Gem★ septic conversion units is the only product available on the market which can treat wastewater from an existing septic tank without the need for a complete replacement product or drainage field upgrade.To comply with the GBRs and current EN standards, the entire Uni:Gem range was redeveloped from the ground up and tested, not only to meet, but to exceed UK and International standards. The Uni:Gem★ was born – creating an ‘industry first’ 2020 compliant septic conversion unit with outstanding processing performance.The Uni:Gem★ range was tested in accordance with BSEN12566-3/A1:2009 and EN12566-6 standards at the PIA GmbH test facility in Aachen, Germany, over the course of 38 weeks with a daily loading of:Flow: 900 litres/day BOD: 360g NH4: 48gTesting occurred between November 2018 and August 2019 to ensure all seasons were covered whilst minimum/maximum temperatures were tested to assure Ammonia and BOD process reduction for the UK climate. Holiday periods were also simulated during the test procedure. Final test results yielded an output of 12.5:16:4mg/ltr (BOD:Suspended solids:Ammonia) that is well within national discharge consent requirements.The Uni:Gem★ is an extremely cost effective solution for converting any polluting septic tank into a fully compliant sewage treatment plant ensuring homeowners, estate managers, water companies/amenities have an effective way to keep the environment clean whilst providing a quick and efficient installation process.

The San Siro playing field was designed to be heated using an under-soil system featuring single-head, in-line electronic pumps.

Based in Newbury, Berkshire, Howard Porter founded Polgate Ltd some 35 years ago. Formerly a Chartered Surveyor, he saw the opportunity to start his own company and has never looked back, developing mainly new build residential and commercial properties within around 25 miles of Newbury. Here we speak to Howard to gain his point of view on the Grant Aerona³ heat pump.

Salthaven Apartments, Tower Road, Poole, DorsetThe Salthaven apartments in Dorset aimed to deliver luxury living for occupants. Bayview Developments not only constructed beautiful homes for them, but also opted for highly energy efficient heating within the new development.Each of the 12 two or three bed apartments have been fitted with their own individual exhaust air heat pump (EAHP). This technology has been installed in buildings across continental Europe for many years but is now being used more commonly within the UK. Bayview Developments were looking to exceed their planning requirements by reducing carbon emissions and providing cost savings for occupants. NIBE’s innovative EAHPs were therefore the ideal solution.The solution to the projectA NIBE F730 EAHP system removed the need for gas boilers, something Bayview were keen to do given the UK’s net zero targets and commitment to phase out the technology. As heat pump technology is powered by electricity, no gas has been installed at the site.The NIBE F730 unit can be found in the utility room cupboard of each apartment and is comprised of a ventilation system, a hot water cylinder and a heat pump – a complete ‘all-in-one’ product. It works by drawing warm air from the kitchen and bathroom to feed the heat pump, which extracts the heat energy. The recovered energy from the ventilation system is used to drive the heat pump process, which heats the underfloor heating and provides water for the integrated 180litre hot water cylinder. The stale air from the ventilation system is then released outside, whilst fresh air from outdoors is introduced via wall inlets with cleanable filters. The efficient system minimises energy consumption by combing ventilation heat recovery with heat pump technology, that is perfect for well insulated new build properties such as these.The ResultsThe EAHP systems meet the average annual heat demand of 6019 kWh for each individual flat whilst also providing instant hot water. Occupants are able to schedule their heating to suit their timetable and energy tariffs, and therefore benefit from lower energy bills. The system performance factor (SPF) measures 3.33 – this means the system is very efficient as every kW of electricity used to run the unit produces approximately 3 kW of heat energy.NIBE utilised connected electricity meters in 3 apartments to remotely monitor the systems performance across a 12-month period. NIBE was thus able to see how the systems met energy demand consistently for residents, keeping them comfortable and warm throughout the year.Energy consumption data shown in Figure 1 visualises electricity consumption data from the monitored apartments throughout the year. This data also covers the provision of all heat pump controls and continuous mechanical ventilation.Figure 1: 2022 Energy Consumption data for monitored apartments.The all-in-one system has shown a noticeable reduction in energy bills for each apartment too, with all 3 monitored apartments experiencing both monthly and cumulative cost reductions in their energy bills as shown in Figures 2 and 3. This comes with the additional peace of mind that consumers will be kept cool in the summer months with ventilation with no increase in costs.Figure 2 and 3: Monthly and Cumulative Heating Bills for Apartment 11 with the NIBE F730 heat pump compared to a natural gas boiler.The occupants of Apartment 11 are saving on average £130 on their annual heating bills with the heat pump system in comparison to a natural gas boiler, even with the additional provision of mechanical ventilation. We expect that these savings will continue to increase as the Government seeks to rebalance green levies to decrease electricity prices.Sunstone Energy Ltd, the installer for this project, told us how easy the control system is to use for this heat pump, allowing for heating and hot water to be available at any time during the day. The building also benefits from insulation, underfloor heating, smart controls, double glazing, hot water cylinders and mechanical ventilation with heat recovery (MVHR).TestimonialVictoria and John are both residents of the Tower Road apartment complex and have been comfortably living with the exhaust air source heat pump system for a year. They added “We are delighted so far with the new heating system, and love that it has been providing us with heating and hot water throughout the year, keeping us warm in the cold winter months. The heat pump works just as well as our older systems and it is great to know that we’re also doing our bit for the environment in the process.”About the installerSunstone Energy Ltd takes responsibility for delivering complete renewable solutions appropriate to their client’s properties.

Background to the projectSouthway Housing Trust is a South Manchester based housing association managing 6,000 local homes.Southway has pledged to be zero-carbon by 2038 and has identified switching its homes from gas to electric heating as crucial to achieving this target.In 2022, a survey of Southway’s residents found that 88% were keen to reduce their impact on climate change, and Southway’s commitment to reducing carbon is in line with Manchester City Council’s net-zero ambitions.The Arrowfield Low Carbon Living Project represents an early and ambitious retrofit of a south Manchester neighbourhood that will reduce the estate’s carbon footprint by as much as 50%.Southway is replacing 396 of Arrowfield’s inefficient gas boilers in-line with long term government plans to electrify heat and will also improve the fabric of homes to make them more energy efficient.The scale of the project, part funded by the European Regional Development Fund (ERDF), has made it one of the UK’s biggest home retrofit schemes.NIBE products used:NIBE F2040 Air Source Heat PumpKey stats:112 NIBE F2040 Air Source Heat Pumps installedContributes to project to remove 370 tonnes per annum of CO2 in ArrowfieldInstalled by Rothwell Plumbing GroupPart of a project to retrofit 199 homes with air source heat pumpsThe solution to the projectArrowfield Low Carbon Living is a flagship scheme in Manchester, retrofitting 199 homes and 197 apartments with air source heat pumps. NIBE was chosen as one of two heat pump providers to bring low carbon, sustainable heating to residents living in the Arrowfield estate. NIBE’s high quality, reliable heat pump systems provide optimum savings and automatically adapt to each home’s output requirements.Rothwell Plumbing Group (RPS) was chosen as the installation partner for the project, with a proven track record for delivering high quality heat pump systems, in both the public and private sectors. RPS are also MCS & Trustmark accredited, with the experience and technical ability to install NIBE systems to the highest of standards.Southway’s aim is for the project to act as a learning process and blueprint for how it can scale up the retrofitting of its entire housing stock over the next 15 years.Ahead of this ambitious project, a community engagement programme enabled greater awareness of heat pumps as a low carbon heating solution, whilst providing the opportunity to listen and respond to resident feedback.The Arrowfield Hub, located in in a repurposed empty house on the estate, became a venue for regular engagement between the residents and the project team, creating an open forum for questions and comments on the proposed scheme.The Hub was also heated by an air source heat pump, allowing residents to witness a live heat pump in operation and experience the warmth of the building.Residents were also able to express their concerns surrounding the project, and these could be addressed accordingly. This regular and open engagement was key to keeping residents informed and more familiar with their soon-to-be new heating systems.The Hub also allowed for the project team to dispel common myths and misconceptions about air source heat pumps and reassure residents that their homes would remain warm throughout the yearThe Results112 NIBE’s F2040 Air Source Heat Pumps have been providing heat and hot water to residents across the estate, adapting to the requirements of each and every home in the estate, whilst providing powerful output even down to outdoor temperatures as low as -20°C.The systems will provide homes across the estate with optimised energy and cost savings, whilst supplying a supply line temperature of up to 58°C regardless of outdoor temperatures.TestimonialMatt Roberts, Strategic Director of Property and Development at Southway Housing, said:"Community engagement for the Arrowfield Low Carbon Living Project was central to the project's aims. Foregrounding the needs of Arrowfield's residents as central to the project’s implementation, helped us to better convey the benefits of low carbon heating and address concerns and suggestions brought forward by homes set to benefit from the retrofit scheme.Air source heat pumps are essential to Southway Housing Trust decarbonising our housing stock and achieving our net-zero goals. Working in partnership with NIBE is part of that process and has contributed to achieving carbon savings of 370 tonnes CO2 per annum on Arrowfield.”About the installerRothwell Plumbing Services Group Ltd, formed in 1997, are a family run business specialising in delivering renewable solutions across the North of England.
