Eco-Friendly Plumbing &Water Conservation
A practical guide for homes in Andover (SP10/SP11), Marlborough (SN8) and Hungerford (RG17) - which water-saving measures are worth doing, roughly what they cost, and which of them Will fits himself.
Why Choose Eco-Friendly Plumbing?
Most of the cost of a shower is heating the water, not buying it. Use less and you pay twice over.
Every litre of hard water that goes through a cylinder or a shower leaves something behind. Fewer litres, less scale.
Our tap water and our rivers come out of the same chalk. Using less at home leaves more in the stream.
🌱 A note on the numbers
You will see a lot of confident percentages quoted for eco-plumbing - “cuts your bill in half”, “pays for itself in two years”. Rosebourne has not measured any of that, so this guide does not quote it. What it gives instead is flow rates and litres per flush, which you can check on any product’s own specification, and honest cost ranges.
For independent, measured figures on energy and water saving measures, the Energy Saving Trust is the place to look - they do the research, and their numbers come with the assumptions attached.
Proven Water Conservation Techniques
Key Benefits:
- Lower water and hot water heating bills
- Less water drawn from the chalk aquifer
- A good shower head at low flow feels no weaker
- Straightforward swap on most existing pipework
Implementation Examples:
- Low-flow showerheads (6-9 litres/min vs 15+ traditional)
- Dual-flush toilets (3/6 litre vs 9 litre traditional)
- Aerator taps (8 litres/min vs 15+ traditional)
- Water-efficient washing machine connections
Typical cost:
£200-800 per fixture
Local note:
Particularly valuable in our hard water areas - less flow means less mineral buildup
Key Benefits:
- Cuts mains water use for flushing and irrigation
- Reduced load on septic tanks and treatment plants
- A garden water source that survives a hosepipe ban
- Works well on larger rural plots
Implementation Examples:
- Simple garden irrigation systems
- Toilet flushing greywater systems
- Laundry-to-landscape systems
- Constructed wetland treatment
Typical cost:
£1,500-5,000
Local note:
Good fit for rural properties with gardens; building control approval may be needed
Key Benefits:
- Free water for garden irrigation
- Reduced surface water runoff
- Lower water bills
- Soft, unchlorinated water that plants prefer
Implementation Examples:
- Simple barrel collection systems
- Underground storage tanks
- First-flush diverters
- Integrated pumping systems
Typical cost:
£500-3,000
Local note:
Roof runoff on the downs is reliable enough to keep a butt or tank topped up for most of the year
Key Benefits:
- Real-time usage insights
- Leak detection alerts
- Spots the overflowing loo you cannot hear
- Remote monitoring capability
Implementation Examples:
- Smart water meters
- Leak detection sensors
- App-based monitoring systems
- Automatic shut-off valves
Typical cost:
£100-500 for the kit
Local note:
Particularly useful for second homes and rental properties
Advanced Sustainable Solutions
Heat Recovery Systems
What you get
The cold feed arrives warm, so less energy is needed to bring it up to temperature
Typical cost
£800-2,000
Best for: New builds, major renovations
Who fits it: Will fits these - it is pipework and a heat exchanger under the shower tray
What you get
Free heat on sunny days, topped up by your existing system the rest of the time
Typical cost
£3,000-6,000
Best for: South-facing roofs, unshaded
Who fits it: Rosebourne does not supply or install solar thermal - that needs an MCS-registered installer. Will is G3 qualified and can fit or adapt the cylinder it feeds
What you get
Uses considerably less electricity than heating the same water with an immersion element
Typical cost
£2,000-4,000
Best for: Replacing electric hot water systems
Who fits it: Will is G3 qualified and ASHP trained, and fits heat pump hot water cylinders
Sustainable Materials
What you get
Lower carbon footprint in manufacturing
Typical cost
Similar to traditional pipes
Best for: All new installations
Who fits it: Plastic or copper is a per-job call - Will will talk it through on site
What you get
Health and environmental benefits
Typical cost
Usually a little more than basic fittings
Best for: All installations, especially drinking water
Who fits it: Rosebourne is WaterSafe approved, so drinking water fittings have to meet the water regulations
What you get
Keeps heat in the pipe instead of in your loft
Typical cost
Similar to synthetic alternatives
Best for: All pipe insulation applications
Who fits it: Will insulates pipework running through unheated space as a matter of course; the bio-based versions are a straight swap
What Rosebourne does and does not do
Rosebourne is WaterSafe approved and G3 qualified for unvented hot water, and Will is ASHP trained. He is not MCS registered, so solar thermal panels are not something this business supplies or installs - they are included here because people ask about them, not because they are on offer. He is not Gas Safe or OFTEC registered either, so gas and oil boilers are somebody else’s job. Where a green upgrade needs a certified installer, Will will tell you so and will happily do the plumbing that connects it up.
Practical Water Saving Tips
✅ Quick Wins (Immediate Impact):
- Install a low-flow showerhead (£20-50) - 6-9 litres a minute instead of 15+
- Fix leaky taps immediately - a drip runs all night and every night
- Use dual-flush toilets or add displacement devices
- Take shorter showers (aim for 4-5 minutes)
- Turn off the tap while brushing teeth - a running tap is about 8 litres a minute

Water & Drainage Across Our Patch
Rosebourne covers Andover, Tidworth, Ludgershall, Marlborough, Great Bedwyn, Pewsey, Hungerford and Stockbridge, plus the villages around them. The ground under those places is nearly all chalk, and that shapes what is worth doing.
What works well here:
- Water softeners - less descaler, less detergent, and kit that lasts longer
- Rainwater harvesting, helped by soakaways that drain well in chalk
- Low-flow fittings, which scale up far more slowly than high-flow ones
- Proper cylinder and pipe insulation, so heated water stays hot
Local Challenges:
Hard water means more descaling and shorter appliance life if nothing is done about it
What works well here:
- Cutting mains use, because the water in your tap and the water in the stream come from the same aquifer
- Rainwater butts and tanks to slow roof runoff instead of sending it straight to the drain
- Prompt leak repair - a hidden leak on a rural supply can run for months
- Careful drainage design so nothing contaminated reaches the watercourse
Local Challenges:
Groundwater protection is taken seriously here, and the water table can sit close to the surface
What works well here:
- Greywater systems, which suit the larger gardens out here
- Reducing the load on a septic tank or treatment plant by using less water indoors
- Insulating and shortening long hot water runs so less is wasted waiting for it
- Smart monitoring on second homes and holiday lets, where a leak can run unnoticed
Local Challenges:
Off-mains drainage has its own rules, and a long buried supply pipe is an easy place to lose water
