Repairs to and blockages in drains and sewers

Advice to Householders and business owner/occupiers that are connected to main drainage

(Council house tenants and those leaseholders who pay an annual service charge to the Council should ALWAYS contact Housing Repairs on 01322 343800)

The following is general advice, but as with most things there are exceptions to the rule, drainage is no different. If you have a blocked drain/sewer refer to the relevant section below.

Then if you are still unsure regarding ownership of a pipe take further advice, the Council’s drainage section can be contacted at drainage@dartford.gov.uk or telephone 01322 343255.

Public Sewers

Sewage is removed from your home via a network of pipes which may be in public or private ownership.

The large sewers normally situated under public highways are usually owned and maintained by the sewerage undertakers and are known as public sewers. Public sewers may also exist on your property if the pipe was built before 1 October 1937 and serves more than one property.

The sewerage undertaker for this area is either Thames (telephone 08459 200800) or Southern Water (telephone 0845 278 0845). Any problems regarding repair, cleansing and maintenance involving public sewers should be referred to your sewerage undertaker. Generally if you receive a separate sewerage account from Thames or Southern, then you should contact them, if you receive a combined water supply and sewerage account you should contact Thames.

If a sewer does not satisfy these criteria, it is probably not in public ownership and is therefore private.

Private Sewers

The pipes that were built after 1 October 1937 which connect groups of houses to the network of public sewers are in private ownership.

When a pipe drains two or more properties in separate curtilages it is a sewer. Any sewer which is not vested in the sewerage undertaker is a private sewer.

All drains and private sewers are owned and maintained by the owners of the properties which they serve, up to the connection to the public sewer, even if they are situated in land which is outside the curtilage of those properties.

Drains

Any pipe which drains a single property or a number of properties/buildings within the same curtilage is defined as a drain and is private regardless of when it was built.

The cost of relaying private sewers and drains

Householders are frequently confused by drainage law which is set out in several enactments originating in the 19th century Public Health Acts. The purpose of this page is to summarise the relevant responsibilities of private householders.

On housing estates built after 1937 the whole network of drains and sewers (not in the public highway) may be in private ownership which would then be the joint responsibility of all the property owners and/or occupiers served by them.

When major repairs are necessary and private sewers have to be re-laid the cost is borne by the owners of the properties served by those sewers in proportion to the benefit derived from use and not in proportion to the number of properties served. Depending on the terms of any household insurance you may have, you may be covered for most of any repair costs, it would be worth enquiring. The cost of the repair per household is proportional to the length of repaired sewer serving that house and is calculated using a standard formula.

Local Authority Powers

Local Authorities have three main powers for dealing with blockages and repairs to defective private sewers and drains.

Blocked Drains/Private Sewers (not Council house tenants)

The Council provides a 4-hour response drain/private sewer unblocking service through a nominated supplier. The Company providing that service is Mai-Tec Construction, telephone 01424 773434. Residents using this service should contact the Company, and identify themselves as a Dartford resident. It is not essential, but it would help the Company if you know when your house was built and if the blockage is affecting more than one property.

The Company’s charges are;

Monday to Friday (call received before 16.30)     £60 including VAT
Evenings and Weekends                                  £80 including VAT
Bank Holidays                                                £100 including VAT

This is a fixed charge (no hidden extras) and as with other companies the person requesting the service will receive the account. Contributions from neighbours will be the responsibility of the householder, although a standard letter to assist can be provided.

If the Council orders the work on your behalf the charges, valid up to 31 March 2006, would be;

Monday to Friday (call received before 16.30)      £85 including VAT
Evenings and Weekends                                   £105 including VAT
Bank Holidays                                                 £140 including VAT

Failing this the Council can serve a 48 hour Public Health Act Notice. If the notice is not complied with, they may carry out the work themselves and reclaim the expenses from the person(s) concerned by apportionment of costs. This means that the blockage could remain in place for the 48 hours with the extra cleaning costs and administrative costs added to the basic unblocking charge.

Minor Repairs to Drains/Private Sewers

The Council can serve a 7 day Public Health Act Notice of their intention to deal with a drain, private sewer etc that has not been maintained and kept in good repair, it can recover its expenses by apportionment of costs.

Defective Drains/Private Sewers

In dealing with a major defect, affecting a large number of houses the Council may serve a Building Act Notice requiring repair within 42 days. It can recover its expenses by apportionment of costs.
