Water Supply Boreholes: An Outline For Development

Making use of groundwater to save your business money can seem like a daunting process. Here is a simple guide outlining the process from feasibility to installation – and how we can help you.

 
1) Firstly, determine how much water you will need to abstract. This needs to be an estimate of daily and hourly demand – as well as the peak (instantaneous) rate required for your process or business. The amount of water required will affect viability, borehole design and other areas such as licensing. (If you abstract more than 20m3/day you will need an Abstraction License from the Environment Agency). If you are unsure how much water you will need, we are more than happy to help with assessment.

 
2) Initial geological assessment; unlike many companies, as part of our initial contact we will provide a short geological assessment to determine viability of water supply – before you have to spend any money! If we think your site is a candidate for further assessment, we will say so. If it is not worth the outlay – we will tell you that as well.

 
3) The next step is a hydrogeological survey to determine the amount water that is likely to be available from a borehole at your location, the quality of water, potential treatments required for the purpose you require, budget costs and design of the borehole. Not all sites within the UK are able to support a private water supply – but we will maximise your chances to obtain one.

 
4) Once our hydrogeological assessment has been completed we will help to make the decision to proceed with construction. We will then assist in agreeing a contract with a suitably qualified and competent driller. We have longstanding relations with trustworthy drilling companies with the right expertise and plant for a particular project. We can also provide specifications and tender documents to obtain competitive quotes.

 
5) Once the borehole has been drilled we provide the work necessary to test your borehole to confirm sustainable flow rate and water quality. Furthermore, if you are to abstract more than 20m3/day we help with the application process to obtain an abstraction license. Carbon Zero Consulting will help you to meet all regulatory requirements for a private water supply.

 
A well-designed and installed private water supply borehole will meet your needs for many years to come. We provide monitoring and maintenance services for some boreholes that have operated for nearly 100 years! You will not only significantly reduce costs but also have greater security of supply compared to mains water.

UK Renewable Power Generation and Grid Carbon Intensity

Since 2nd June 2015 we have been monitoring the contribution of renewable power generation and carbon intensity of the UK National Grid. A ‘spot’ reading is taken at midday each day.

The addition of wind, solar and hydro-power to existing power generation (gas, coal and nuclear) is starting to make real inroads into the average carbon intensity of the national grid (the amount of CO2 emitted for each unit of electricity generated).

Coal power stations are to be phased out of the UK by 2023 meaning that it is likely that more gas power stations will have to be constructed (new nuclear power installations will take a minimum of 10 years to come on line). The current UK government has put a stop to further onshore wind installations, but there are likely to be more constructed offshore. Likewise, the rate of installation of solar PV, ground source and biomass systems will slow radically with the planned major reduction of tariff payments.

Wind, solar, hydro and nuclear power do not emit CO2 to the atmosphere, while coal and gas emit CO2 with coal being significantly worse than gas.

Graph of UK Grid Carbon Intensity (Nov 4)

As stated in the last article the Carbon Trust states that in all calculations 500 gCO2/kWh is to be used for computation of carbon emissions for heat pumps. However, the value found over the past 4 months is significantly lower than that with an average closer to 385 gCO2/kWh. The result of this is that Ground Source Heats Pumps provide significantly greater environmental benefit than the data published by the Carbon Trust would suggest.

The UK is committed to phasing out power generation by coal (and much later gas) and to increase the contribution from nuclear power and renewable technologies (wind, solar, hydroelectric and tidal). The goal is for power generation to become ‘zero carbon’ by 2050 when all power will be generated by renewable and nuclear means.

Since 2nd June 2015 we have recorded (once per day) renewable power production and the ‘carbon intensity’ of the UK National Grid. The graph shows the percentage of total power generation being met by renewable energy (wind plus hydroelectric) and the resulting carbon intensity of energy produced.

It can quickly be seen how renewable energy generation impacts directly and significantly on the Nation’s Grid carbon intensity.

UK Grid Carbon Intensity

We do not include contribution from nuclear power in the ‘Percentage Renewables’, but nuclear power is also a zero-carbon power generator. Currently, nuclear power provides about 20% of total power produced.

Continued reduction of grid carbon intensity will reduce the UK’s impact on the global rise of CO2 and average temperature. The benefit of lower grid carbon is further enhanced when used to heat our homes and businesses via electrically powered heat pump technologies, such as Ground Source Heating.

Currently, the Carbon Trust states that in all calculations of CO2 emissions from heat pumps, a grid intensity of over 500gCO2/kWh is to be used. However, our findings clearly show the average value is closer to 375gCO2/kWh.

We will continue to plot this data to show the beneficial impact of renewable power implementation.

Busy doing soil surveys!

There has been a bit of a rush on soil thermal conductivity surveys this month. We normally perform 2 or 3 a month, but we’ve done 5 already in July!
Our surveys provide in-situ measurement of soil thermal conductivity at the depth at which a proposed GSHP ground array is to be installed.
We successfully completed domestic scale surveys, a large golf club array near Durham, and another for a new poultry farm in Cheshire.
We are also working with De Montfort University in Leicester on an exciting new piece of research to assess heat storage in soils; we were asked to perform a baseline survey with excavation and measurements down to 2m depth on the 2 hottest days of the year …..a fine welcome to the world of Carbon Zero Consulting for our new recruit, Lawrence Scott!

Recruiting for an Engineer with Earth Science expertise

Position availableCarbon Zero Consulting Ltd, a specialist Renewable Energy and Water management consultancy, is looking to recruit an engineer with Earth Science expertise with about 3 years’ experience. Carbon Zero Consulting is a small business; well-known and respected within the renewable and water sectors. If you believe that rapid uptake of renewable technologies is not a choice but a necessity, then we would like to hear your views! You are likely to have a second degree and may have been working in areas of geology, engineering or hydrogeology. You must enjoy hands-on field work (sometimes remote – and often in the pouring rain!) in addition to desk-based report writing, computation and design modelling. You will also be the type of person who wants to grow the business by pursuing new ideas, managing your own projects and building relationships with clients: old and new.

At an early stage in your career, we will provide you with full support but you will need a high level of independence and the ability to solve problems alone while being an important part of a small team. You will be involved in all aspects of running and growing a small business so you must have ability to clearly communicate with clients through well-written reports and emails – and be very comfortable with IT and social media.

At our Rutland office, we provide a very friendly, casual and flexible approach to working life, although a very high standard of work and professionalism is expected at all times . You will learn new technical and business skills within a sector that we believe is due for massive growth over the coming decades. Carbon Zero Consulting will be very much a part of that growth.

We will provide a competitive salary including a share in company profits and a contributory private pension. The nature of the work means you will be prepared to work away from home on occasion. You will need your own car (we will pay mileage allowance) and a full UK driving licence.
