CLEARMASTERS
Blocked drains on flat ground
With little fall, drains in Sunbury run slowly and collect silt, fat and debris. We clear them with high-pressure jetting and tell you what caused the blockage.
Learn moreSunbury-on-Thames is a riverside town in Spelthorne, with Shepperton, Ashford and Laleham close by and big reservoirs all around. It’s flat, low and almost entirely on mains drainage, with homes ranging from riverside cottages to large estates, and business parks around Sunbury Cross and the M3.
Flat ground means slow drains that silt up easily, and the Thames floodplain means flooding and high groundwater in very wet winters. Many riverside homes and some business sites rely on pumps to get waste to the sewer. Restaurants and takeaways need grease traps emptied, and business parks need gullies and interceptors cleaned.
Our crews are in Spelthorne most days and we answer the phone 24 hours a day, 365 days a year.

What we do for Sunbury customers
Pump stations for riverside homes and sites
Riverside homes, basements and some business sites rely on pumps to reach the sewer. We service them, test pumps, floats and alarms, and respond 24/7 when one fails.

Flood water removal
When the Thames floods or groundwater rises, our tankers can pump water out of basements, gardens, chambers and car parks and take it away.

Grease traps, gullies and interceptors
Restaurants and takeaways need grease traps emptied; business parks need gullies and interceptors cleaned. We set up regular schedules and provide waste transfer notes.

Drainage around Sunbury: what to know
Flat, low and next to the Thames.
Very little fall
Drains on flat ground run slowly. Regular jetting on commercial sites stops silt and fat building up.
Riverside pumps
Homes close to the river often rely on pumps. Servicing them before winter is the best protection.
Floods and groundwater
In very wet winters, river and groundwater flooding can affect low-lying streets and basements.

How it works
What happens when you book
The same simple process for every job.
-
Step 1
Tell us what you’ve got
Call us or book online and tell us what’s happening. If there’s flooding or a pump alarm, call rather than book.
-
Step 2
We come out and do the job
We send the right van, tanker or engineer. It helps if:
- you tell us if there’s standing water on the drive or around the chambers
- covers and the pump chamber are clear and easy to reach
- someone can show us the pump control panel or alarm box if you have one
-
Step 3
Paperwork and the next visit
You get a waste transfer note for anything we take away, and a written report after a survey or service. If it’s a regular job, we’ll remind you when the next one is due.

Questions answered
Sunbury drainage FAQs
What homeowners and businesses in Sunbury ask us most.
Why do drains in Sunbury block so easily?
The ground is very flat, so drains have little fall and water moves slowly. Silt, fat and wipes settle and build up. Regular jetting helps.
My riverside home has a pump. How often should it be serviced?
At least once a year, ideally before winter. If it handles all the waste from the house, more often may be wise.
Can you pump out a flooded garden or basement?
Yes. Our tankers can remove flood water and take it away, then we can check the drains and pumps.
Do you empty grease traps for restaurants?
Yes. We set up a regular schedule and leave a waste transfer note each time.
Do you clean gullies at business parks?
Yes. We clean gullies and interceptors at business parks and car parks, with waste transfer notes for your records.
Are you available out of hours?
Yes. We answer the phone 24 hours a day, 365 days a year. Call 03333 233566.
