• It is essential that you hire a Licensed Sanitary Constructor (Licensed Plumber) who will handle all your business with the Authority. The Constructor must first apply for approval to install a plumbing system on your premises.
• Together with the Sanitary Constructor, an application form for connection to WASA's sewerage system must be filled out and subsequently submitted to the Authority with four (4) copies of the plumbing isometric drawings.
• With the submission of the application and drawings, processing fees must be paid. The fees differ depending on the usage of the particular property and are priced as follows:
  

  Residential:	$150 + VAT
  Multi-unit Residential:	$150.00 + VAT per unit
  Commercial:	$200.00 + VAT/Floor
  Industrial:	$450.00 + VAT/Floor
  Institutional:	$500.00 + VAT/Floor
  Swimming Pool/Residential:	$500.00 + VAT
  Swimming Pool/Commercial:	$1000.00 + VAT

• Approval of plans takes between seven to ten (7-10) working days, where first time submissions are satisfactory and in accordance with the National Plumbing Code of Trinidad and Tobago.
• If the drawings are within code requirements, they will be issued to the Constructor, who then applies for inspection at the property.
• If work is done according to the approved plans and code, then the Licensed Sanitary Constructor applies for a sewer connection and pays the appropriate fee as follows:
  
  

  Residential:	$1200.00
  Commercial:	$2500.00
  Other:	$1200.00 per unit
  These fees are Not VAT-able.

• Upon completion of the sewer connection and approval from the Plumbing Inspectorate , the Authority will issue a Completion Certificate.
• N.B. These applications may require prior Developmental Approvals.
• A list of Licensed Sanitary Constructors is available at the Plumbing Inspectorate, New Services Department

First, call your Licensed Sanitary Constructor, to determine whether the problem results from the private service connection or the Authority's sewerage system. If the problem lies with the Authority's system, contact our Wastewater Departments as follows:
