Use this category for costs incurred in connection with the **property's drainage** which are to be recovered from the tenants.

These include in particular costs for:

* waste water charges
* foul water charges
* precipitation water or rainwater charges
* sewer charges
* charges for house and property drainage
* the running operating costs of a private drainage system, for example a small sewage treatment plant or a collection pit
* the costs of operating a drainage pump or lifting unit
* regular maintenance or cleaning costs, as far as they serve the running operation of the drainage system
* charges for house and property drainage
* the costs of operating a non-public drainage system or drainage pump

#### When to use this category

Choose this category where you have an invoice, a charge notice or a statement for **waste water, drainage, sewers or foul water**.

#### Important

Only enter **running costs** of the drainage here. Repairs, maintenance or refurbishment may **not** be recovered from the tenants. Section 1 (2) BetrKV expressly excludes maintenance and repair costs from operating costs.

Items that do not belong in this category are, for example:

* repairing a waste water pipe
* replacing or renewing a defective drainage pump
* dealing with a burst pipe
* renovating sewer pipes
* one-off connection costs or sewer construction contributions
* other measures to remedy damage

{% hint style="info" %}
Such costs are **to be borne by the landlord** and may **not** be allocated to the tenants as operating costs.
{% endhint %}

Only running operating costs are recoverable, and only under an effective agreement with the tenant. What matters are [Section 556 BGB](https://www.gesetze-im-internet.de/bgb/__556.html) and [Sections 1 and 2 BetrKV](https://www.gesetze-im-internet.de/betrkv/__2.html).
