Details:
The Council may design and supervise new land drainage projects or supervise maintenance of land drainage works on its own land. Advice is given to private individuals regarding problems with land drainage and in respect of maintenance and improvements of land drainage channels which are their responsibility. All matters pertaining to public sewerage are dealt with by Southern Water Services Limited. 'Main rivers' are dealt with by the Environment Agency.
 
The Council's Environmental Health team will investigate problems and offer advice as part of its Public Health duty. However please note that we rarely have information about the routes of drainage serving your individual property, and it might be quicker and easier to get a private contractor to find this out for you.

    

 

 

 
 

What is a drain?

A drain is a pipe which conveys either foul water (sink / bath / toilet etc.) or surface water (rain) from one house only.
 
The owner or occupier of a house is solely responsible for maintaining a drain, clearing blockages and repairing any faults. Even where the drain extends outside the boundary of the property (for example under the road or under a neighbour's garden) the owner or occupier of the house served by the drain is still responsible, right up to the main public sewer (see diagram below).
 
 

What is a sewer?

A sewer is a pipe which conveys either foul water or surface water from more than one house.  A sewer may be either PUBLIC or PRIVATE, and can carry clean ('surface') or dirty ('foul') water. In this area, the two systems (foul and surface) are mostly separate.
 
  • A Public Sewer is a sewer adopted and maintained by (in this area) Southern Water >>. Such sewers are usually found under the highway, but can in fact be anywhere. A sewer under a highway is not automatically a public sewer. The Council and Southern Water hold copies of the Public Sewer Maps showing the locations of public sewers. If a sewer is not shown on the Public Sewer Map it will be assumed private unless you can prove otherwise.
  • A second type of Public Sewer was one built as a private sewer before 1 October 1937 but then, as a result of a change in the law, became the responsibility of Southern Water. Plans of this type of public sewer seldom exist, so each case has to be assessed by Southern Water using the evidence available. A site survey (by Southern Water) will often be required.
  • A Private Sewer is the responsibility of the owners or occupiers of the houses it serves. This means that the owners or occupiers of all houses upstream of a blockage or defect are all responsible for clearance or repair. If you live in rented accommodation you should contact your landlord to clarify your responsibilities regarding sewers serving the property you are renting.
To try to explain this further, consider the two blocks of houses in the following diagram. House numbers 1, 3 and 5 were built in 1936 and numbers 7, 9 and 11 were built in 1938. If a blockage occurs at "A", clearing it will be the responsibility of Southern Water, since any pipe serving more than one property built before 1st October 1937 is automatically a public sewer. However, if a blockage occurs at "B", clearing it will the responsibility of the owners of numbers 7, 9 and 11 even though it is in the garden of number 11. In fact, even if blockage "B" occured under the road or footpath, it would still be the responsibility of the owners of 7, 9 and 11 to clear, since pipes serving properties built after 1st October 1937 are private until they connect to the public sewer, however far from the properties that may be.

If my property has a private drain or sewer, why do I pay Sewerage Charges?

The bulk of the Sewerage Charge is spent on treatment and disposal of foul sewage at a network of Waste Water Treatment Plants. Most of the Borough drains to Budds Farm in Southmoor Lane, although Emsworth drains to Thornham in West Sussex. The Sewerage Charge is also spent on the maintenance of the public sewer network into which the private systems connect.
 
If you can prove that surface water from your property does not drain to the public sewer, for example that it drains to a soakaway, then you can obtain an exemption of the surface water part of the Sewerage Charge. Contact Southern Water to arrange this.
 
 

When I bought my property, the Search said the property was connected to the public sewer. Don't I have a private sewer or drain?

The search question only asks whether the property is ultimately connected to the public sewer system, for the purposes of finding out whether the Sewerage Charge is payable by the occupants. It doesn't search for the method of connection, which is irrelevant to the payment of the Charge. Every property will have at least a private drain, and properties built after 1st October 1937 will probably have lengths of private sewer as well.
 
 

Where can I find out what private drains and sewers serve my property?

This information will usually be shown on your property Deeds. Unless the property was built very recently, the Council will have no record of the private drainage serving your property (we would only know the route through the Planning Permission issued for the property when it was built). If the information is not shown in your Deeds, you will have to organise a private survey to trace the routes of the pipe work. 
 
 

Who is responsible if I rent my property?

If you rent your property and have a problem with the sewerage, you should contact your landlord.
 
 

What can I do if my drain or private sewer blocks?

During the normal working week, the Environmental Health service can, in most cases, clear the blockage by rodding, for which a charge is payable. A list of charges is available here >>. Alternatively, you may choose to employ a private contractor who, in addition to rods, may have powered jetting equipment which is sometimes preferable; there is a wide choice to be found in Yellow Pages>> under "Drain and Pipe Cleaning". Always ask for a quote before employing any contractor, and check whether your household insurance will cover the cost.
 
Where several houses are affected by a blockage in a private sewer you should try to agree to share the cost with each householder before employing a contractor. The Council will not become involved in disputes where householders cannot agree between themselves the sharing of these costs.
 
 

What can I do if a public sewer blocks?

Public sewers are the responsibility of Southern Water. Telephone them on 0845 278 0845 to report the blockage, giving as much information about the problem as you can or email them at customerservices@southernwater.co.uk.
 
 

What happens if my drain or private sewer requires repair?

You should arrange for repair by a contractor. The cost of repair to a private sewer should be shared by the various householders which the sewer serves.
 
Your Buildings Insurance Policy may cover the cost of repairs - look under the "Accidental Damage to Services" clause in your Policy. Alternatively there are a number of repair policies commercially available, often offered by the water companies themselves.
 
 

What happens if I don't clear the blockage or carry out repairs?

Havant Borough Council has public health powers under various Acts of Parliament including the Building Act 1984, the Public Health Act 1961 and the Local Government (Miscellaneous Provisions) Act 1976 - these allow us to demand the clearing of blockages or carrying out any repair works in the private part of the drainage / sewerage network. This is done by the Council serving a legal Notice on the relevant owners. Failure to comply with this Notice is an offence, which can lead to prosecution. If the owners do not comply with the Notice, the repairs may be carried out by the Council in default with the full costs being recovered from the owners.
 
 

What do I do if a road gully blocks?

Road gullies on the public highway are the responsibility of the highway authority, Hampshire County Council, to maintain. Road gullies are designed to only drain the highway, so it is not permissible to direct water from your property directly into them.
 
Hampshire County Council Highways organises the cleansing of every road gully and drain on a rota basis, so that each gully is cleaned at least once a year. In between cleans, it is possible for a gully to block (especially in areas with lots of trees, in the autumn) so report any requirements for special cleans to Customer Services by email to roads@hants.gov.uk or if urgent by telephone on 0845 603 5633.
 
In a small number of instances a gully may be in a private area (such as a garage compound), in this case it will be for the landowner(s) or landlord (if properties are rented) to maintain.
 
 

Can the Council offer advice?

Yes. The Environmental Health team will be pleased to investigate problems and offer advice as part of its Public Health duty. However please note that we rarely have information about the routes of drainage serving your property, and it might be quicker and easier to get a private contractor to find this out for you. If you have any queries, do not hesitate to make contact either by email to customer.services@havant.gov.uk or by telephoning (023) 9244 6017.
