Regular Emptying Scheme
for Septic Systems
CSG’s Regular Emptying Scheme makes it easier to arrange scheduled emptying for your septic tank, cesspit or sewage treatment plant. It’s free to join, with discounted collection rates and reminders before your emptying is due.
By grouping collections in the same area, we can plan efficient routes and pass the savings on to you. Regular emptying helps reduce the risk of overflowing tanks and sludge build-up, while supporting the ongoing care of your off mains drainage system.
Our Regular Emptying Scheme helps households and businesses plan routine sewage collections without having to book each visit individually.

How Does the Regular Emptying Scheme Work?
To reduce fuel use and improve efficiency, we plan our collections so that multiple properties in the same area are serviced together. Those cost savings from smarter route planning then get passed on to you.

What You Can Expect
As a Member of The Scheme?
The scheme works particularly well if you and your neighbours join together and book collections for the same day, helping everyone save even more.
- We’ll schedule your collections on your behalf
- You’ll receive a reminder 3–4 weeks before your emptying is due
- You don’t need to be at home — as long as there’s safe, clear access
- Friendly, experienced drivers who respect your property and surroundings
Is the Regular Emptying Scheme Right for Me?
The scheme is designed for customers who want planned collections and can provide reliable access to their tank. Read the points below to see whether it suits your property.
The Regular Emptying Scheme is ideal if:
- You want a simple, hands-off approach to sewage emptying
- You have reliable access to your tank
- You’re flexible on collection dates (exact times can’t be guaranteed)
We’ll always be upfront and happy to advise if the scheme is the right fit for your property.
It may not be suitable if:
- You always need collections on specific dates or times
- Access to your sewage system is often restricted (e.g. locked gates)
- Your address isn’t permanent (e.g. houseboats)
- You’re not the homeowner (domestic collections only). Business customers need to set up a CSG credit account.

Frequently Asked Questions
How often do you recommend sewage emptying?
We generally recommend septic tank emptying and sewage treatment plant desludging at least every 12 months, following the manufacturer’s guidance. The frequency depends on capacity and usage. Cesspits may need much more frequent emptying. Our team can help you choose a suitable collection schedule
Can we change how much is collected each visit?
Yes. You can change the volume collected at each visit. Our minimum charge covers up to 1,000 gallons and applies even if less is collected. If more is removed, you’ll be invoiced accordingly. Please let our team know before your collection.
I’m a new customer and don’t know my tank’s capacity. What should I do?
If CSG has not previously visited your property, we will not hold collection records for your system. We recommend an initial collection appropriate for your tank type. The volume removed can help plan future visits, although it may not represent the tank’s full capacity.
CSG empties my tank. Can you confirm whether it’s compliant?
An emptying visit does not include a compliance survey, and our drivers are not qualified surveyors. We recommend an assessment by a suitably qualified specialist to check your system and its discharge arrangements. We can put you in touch with the appropriate people.
Can I cancel the Regular Emptying Scheme or Regular Maintenance Scheme?
Yes. Either scheme can be cancelled at any time. Please email our team to confirm your request, including your property address and account number, if known. If you use both schemes, tell us which regular visits you wish to cancel.
