Yokohama Drainage Equipment Designated Construction Shop

In Yokohama City, construction shops that can perform drainage construction and flushing work are designated as "Yokohama City Drainage Designated Construction Shops" (hereinafter referred to as "designated construction shops").

※In Article 38 of the Yokohama City Sewerage Ordinance, it is stipulated that "construction such as new construction of drainage facilities and remodeling work of Kumitori toilets to flush toilets in the treatment area can only be performed by the mayor designated by the mayor." Therefore, let's ask drainage construction work from designated construction shop by all means.

■When drainage facilities such as flush toilets are clogged
If indoor drainage facilities (toilets, kitchens, bathrooms, washing machine yards, washrooms, etc.) are clogged, drain water from indoor drainage facilities other than the clogged area before consulting or requesting a designated construction shop. Please make sure that the flow of a specific location is bad or the overall flow is poor.
If you live in an apartment such as an apartment or apartment, please consult with caretaker, the management company or apartment owner.

※If the clogged area is an indoor drainage system managed by you or a drainage pipe in a residential area
　→Please consult with a contractor who constructed the water around your home, a drainage contractor you know, or a Yokohama city drainage facility designated construction shop near you.
　→In the case of only removal or cleaning of drainage pipes in residential lands without construction, it can be done even if it is not a designated construction shop.
※When the flow is poor overall or the drainage situation was checked, but it is not clear where the cause of the clogging was.
　→Please consult with your Public Works Office.

■Attention when requesting a designated construction shop
Explain the condition of the place to be requested, discuss the details of the construction and the contracted amount of money, etc., and make a request (contract) after consent.
　・ Let's have multiple designated construction shops issue quotes.
　・ When requesting a quote, check the quote fee and travel expenses.
　・ Let's check the contracted amount, content, and time (construction period) for repairs and construction.
※Please ask me
Some designated construction shops may not be able to receive requests due to the balance with other work or the type of construction / repair, etc., or some construction shops do not clean toilet drain pipes (without construction). Please note that.
