Application for determining conditions for connection to water supply, sewage and gas networks

---

The procedure for obtaining connection conditions to water supply, sewage and gas networks is a key stage of any construction investment in Poland. This comprehensive step-by-step guide will take you through the entire process, explain the required calculations and present practical advice based on current regulations from 2024.

What are connection conditions?

Connection conditions are a technical document issued by water and sewage or gas companies, which defines the principles on which it is possible to connect your property to the network. This document contains technical parameters of the connection, connection point and requirements for the installation.

When do you need connection conditions?

Connection conditions are necessary in the case of:

• Construction of a new residential or commercial building
• Extension of an existing building that increases media demand
• Change of building use
• Installation modernization requiring increased capacity

Connection conditions to water supply and sewage networks

Step-by-step procedure

1. Documentation preparation

Before submitting an application for connection conditions to water supply and sewage networks, you must prepare:

• Completed application - form available on the website of the local water and sewage company
• Site plan - sketch or map on a scale of 1:500, 1:1000 or 1:2000 showing the location of the property
• Water consumption and sewage discharge calculations - our water and sewage consumption calculator proves invaluable here

2. Required calculations

The application must include calculations of the following parameters:

For water supply installation:

• Daily water consumption (Qd) in m³/d
• Average hourly water consumption (Qh) in m³/h
• Maximum instantaneous water consumption (Qs) in dm³/s

For sewage system:

• Daily sewage discharge in m³/d
• Average hourly sewage discharge in m³/h
• Maximum instantaneous sewage discharge in dm³/s

Connection conditions to gas network

Procedure for gas connections

1. Determining the tariff group

Before submitting the application, you must determine your tariff group:

• Group B, subgroup I - single-family houses (consumption up to 10 m³/h)
• Group B, subgroup II - larger residential buildings and small service facilities
• Group A - large industrial and commercial facilities

2. Required gas calculations

An application for connection conditions to the gas network requires determining:

Connection power of gas devices:

• Total power of all devices in kW
• Maximum gas flow in m³/h
• Annual gas consumption in m³/year

Building characteristics:

• Type and standard of thermal insulation
• Heated area
• Type of gas installation (heating, hot water, cooking)

3. Documents for gas application

• Completed form - available from the distribution network operator
• Site map with marked location of gas cabinet
• Gas consumption calculations - use our calculator
• Power of attorney (if the application is submitted by another person)

Practical recommendations

1. Always plan with reserve - it's better to slightly overestimate demand than underestimate it
2. Check local standards - different regions may have different requirements
3. Consult with the designer - it's worth consulting calculations before submitting the application
4. Keep copies - all documents may be needed during design

Using calculators

Our calculators have been developed in accordance with current Polish standards:

Water and sewage consumption calculator:

• Calculates parameters according to PN-92/B-01706
• Takes into account different types of buildings
• Automatic unit conversions
• Export results to application

Gas consumption calculator:

• Gas appliance database
• Annual consumption calculations
• Analysis for different building standards
• Connection power calculation

Most important legal regulations

Procedures are regulated by:

• Water Law Act (Journal of Laws 2017 item 1566)
• Energy Law Act (Journal of Laws 1997 No. 54 item 348)
• Regulation on technical conditions (Journal of Laws 2019 item 1065)
• Standard PN-92/B-01706 for water supply installations
• Standard PN-91/B-10425 for gas installations

Frequently asked questions (FAQ)

Can I submit an application without being the owner of the plot?

Yes, you can submit an application as an inquiry about the possibility of connection. However, full connection conditions will be issued only after obtaining legal title to the property.

What if the planned investment is far from the network?

If your property is distant from the existing network, the company may require infrastructure expansion. The costs of such expansion are often borne by the investor.

Can connection conditions be modified?

Yes, you can apply for a change of conditions, but this requires submitting a new application and re-examining the case.

How long are connection conditions valid?

Connection conditions have a specified expiration date - minimum 60 days from issue. After this period, they may require renewal.

What if the demand turns out to be greater than estimated?

If actual consumption significantly exceeds the parameters from the connection conditions, it will be necessary to apply for new conditions with higher parameters.

Summary

Obtaining connection conditions is a standard procedure that, with proper preparation, proceeds smoothly. The keys to success are:

1. Accurate calculations - use our online calculators
2. Complete documentation - check all required documents
3. Timely submission - remember about processing deadlines
4. Planning with reserve - it's better to slightly overestimate demand

Remember that each municipality may have slightly different procedures and requirements. Always check current information on the website of the local water and sewage company and gas network operator. Our calculators comply with nationwide standards and will work throughout the country.
