Drainage for Barn Conversions Around Liphook
2 min readLiphookBy AA Drainage
Barn conversions on the Hampshire, Surrey and West Sussex borders around Liphook are rarely near a public sewer. Planning the drainage early is essential.
Your main options
Depending on the site, the choices are:
- A sewage treatment plant with a drainage field or watercourse discharge
- A pumping station lifting waste to a distant sewer
- A septic tank with a drainage field where ground conditions are very good
Things to check first
We check the distance to any sewer, the soil type, the size of the plot, and whether there is a ditch or stream with year-round flow. Planning conditions often ask for this detail.
Sandy soils around Liphook
Parts of the area have free-draining sandy soils, which can suit drainage fields well. A percolation test confirms this before design.
Frequently asked questions
Can several converted barns share one system?
Yes, a shared treatment plant is common, but agree who maintains it.
Do I need a permit?
Not if you meet the General Binding Rules. Larger discharges may need a permit.
