  • Domestic customers: for residential and domestic usage only.
  • Non domestic customers: for any agricultural, commercial, fisheries or industrial activities.
  • Government: for State authorities and administrations or public service entities (the payer being a governmental entity).

Types of Connections:

  • Temproray

Connection works and fees

Our technical team will contact you to offer you 3 quotations for the connection works. You may have the possibility to pick another contractor if it is registered with Diam.

Once the payment is done a ticket will be open to launch the connection works which should be finalized.

To change the type of connection from temporary to permanent, the customer has to come to the Branch Office and present the certificate delivered by the Municipality confirming the completion of the house. If there are no unpaid bills, the Customer Service Front Office agent will change the tariff (from commercial tariff (3 baizas) to his new customer category tariff.

How to pay your bill?

Diam provides a bill which is a simplified monthly invoice detailing the information for billing of water and sewage services.

Here are some guidelines to facilitate understanding your bill:

  • Always ensure the accuracy of your name and address.
  • Pay attention to the date for payment.
  • Check that water and sewerage (in Muscat only) are billed on the same month and the same period.
  • Check the time of consumption and meter reading records.
  • View detailed billing: slices, tariffs, other fees.
  • Read some custom messages that inform you of new services offered.

The tariff

Your consumption of water is divided into slices corresponding to specific rates. Rates vary from one slice to another. The more you consume, the more expensive the price.

Consumption brackets are detailed in the table below:

How to pay your bill

OIFC: www.oifcoman.com

ONEIC: www.oneic.com.om

Deadline

The deadline(as Due Date) for payment is indicated on your invoice. Beyond that date, the default will result in suspension of water supplies.

High bill consumption

In case of high bill consumption, Diam advises you to:

  • Check if there is no leakage in your internal network. You can do it yourself! For that, you just have to close all the taps and look at the meter. If it is running, you may have a leakage. This leak may be hidden in the ground or the walls or at the level of your tank on the roof.
  • Contact one of our Branch Offices. Our Customer representatives will analyze your billing history and in case of normal consumption, a check-up of your internal network (after the meter) will be proposed to you free of charge. If you have a leakage, you will have to repair it as soon as possible. Your bill will be reviewed according to the procedure in service.

If you need to relocate your meter from inside to outside your property, from ground to wall, from one place to another more convenient place, we invite you to visit one of our branches and ask for meter relocation with your ID card, if you are the owner, or with a letter signed by the owner, if you are a tenant.  A “Ticket” will be open to launch a survey. If the survey is positive (if relocation is possible), the works will be done by one of the specialist contractors registered with Diam. No specific fee is required.

Diam requesting relocation of meter:

For technical reasons such as meter reading not possible because the meter is underground, Diam may relocate your meter. The works will be done free of charge.

Your meter may be damaged. Visit your nearest branch (), as soon as possible, and ask for a meter replacement with the evidence of the damage(a photograph). A survey will be done by our technical team to identify the reason of this damage, the meter will be replaced and your billing account adjusted according to the procedure.
