CLEARMASTERS
Septic tanks and cesspits
We empty septic tanks and cesspits at homes and farms around Lymington and check the tank while we’re there. On heavy forest soils, regular emptying keeps solids out of the drainage field and helps it last.
Learn moreLymington is a harbour town on the Solent, with a Georgian high street, marinas and a ferry to the Isle of Wight, and the New Forest just to the north. The town is on mains drainage, but the villages behind it, such as Boldre, Pilley, East End, South Baddesley and parts of Sway, have many homes on septic tanks, cesspits and treatment plants.
Near the coast, ground is low and the salt marshes are protected. Inland, the forest soils can be heavy and slow to drain. Both make life harder for drainage fields. And, like the rest of the New Forest district, new homes here are expected to be nutrient neutral to protect the Solent.
In town, restaurants, pubs and cafés need grease traps emptied and drains kept clear. Our crews are in Hampshire most days and we answer the phone 24 hours a day, 365 days a year.

What we do for Lymington customers
Treatment plant servicing and repairs
Treatment plants need servicing at least once a year to keep the water they discharge clean, which matters this close to the Solent. Our engineers service the common makes, carry common parts and repair them when they fail.

Grease traps for restaurants and pubs
Lymington’s restaurants, pubs and cafés need their grease traps emptied before fat reaches the drains. We set up a schedule to suit your kitchen, with extra visits in the busy summer months if you need them.

Drain clearance and CCTV surveys
From period houses on the high street to newer homes in Pennington, we clear blocked drains with high-pressure jetting and survey them with CCTV when problems keep coming back.

Drainage around Lymington: what to know
Between the forest and the sea, drainage needs care.
Protected coastline
The marshes and the Solent are protected for wildlife. A septic tank that discharges into a stream or ditch must be upgraded under the General Binding Rules.
Heavy forest soils
Inland, many soils drain slowly. Drainage fields can stay wet through the winter.
Nutrient neutrality
New Forest District Council expects new homes to be nutrient neutral. If you’re building or converting, it affects your choice of treatment plant.

Questions answered
Lymington septic tank and drainage FAQs
What homeowners and businesses around Lymington ask us most.
Does my septic tank near the coast need upgrading?
If it discharges directly into a stream, ditch or the sea, yes: the General Binding Rules require it. If it goes to a working drainage field, it can usually stay. Read the rules on GOV.UK.
What does nutrient neutrality mean for my new home?
New homes in the New Forest district must show they won’t add nutrients to the Solent. If you won’t be on mains drainage, that affects the treatment plant you choose and may need extra mitigation. Speak to the council early.
How often should my treatment plant be serviced?
At least once a year. Most also need emptying about once a year, and we can do both on one visit.
Can you empty grease traps more often in summer?
Yes. Many Lymington businesses are busier in summer, and we can adjust the schedule through the year.
Can your tankers reach properties in the forest villages?
Usually. We have tankers in different sizes and long hoses. Tell us about narrow lanes or soft verges when you book.
Can you help in an emergency?
Yes. Our crews are in Hampshire most days and we answer the phone 24 hours a day. Call 03333 233566.
