The Isogo Pumping Station is a relay pumping station for collecting sewage from the treatment zone, draining rainwater, and sending sewage to Nambu Wastewater Treatment Plant.
It started operation in 1965, with staff stationed during the day and remote monitoring from Nambu Wastewater Treatment Plant at night to save labor in maintenance.

The Mansei Pumping Station is located adjacent to Nakamurakawa, and is a pumping station designed to eliminate flooding in Yoshino-cho, Takasagocho, Hiecho, Banseicho, Urafunecho, Naka Ward, Isezakicho, Nogecho, Fukudomimachi, Kotobukicho, Nishi Ward, and Hanasakicho.
In the event of heavy rain, rainwater flows into the rainwater trunk line from the sewer trunk line and flows into the Mansei pumping station.
At the Mansei pumping station, rainwater that has flowed in is drained to Nakamurakawa using a large pump to prevent damage caused by flooding in advance.
In addition, part of the upper part of the pumping station is effectively used as fire brigade warehouses and squares.

The Yoshino Pumping Station is located at the junction between Ookagawa and Nakamurakawa rivers and is a pumping station designed to eliminate flooding in Kamiookanishi and Okubo in Konan Ward and Idogayashimomachi, Nakamachi and Minamiotamachi in Minami Ward.
In the event of heavy rain, rainwater flows into the rainwater trunk line from the sewer trunk line and flows into the Yoshino pumping station.
At the Yoshino pumping station, rainwater that has flowed in is drained into the Ookagawa and Nakamura rivers using a large pump to prevent damage from flooding in advance.
In addition, the upper part of the pumping station is effectively used as Yoshinocho Civic Plaza.

Isogo No. 2 Pumping Station is adjacent to Tokyo Bay and is a pumping station mainly aimed at eliminating inundation in the area around the digging river.
The pumping and water reservoir facilities temporarily store early rainwater in rainy weather, send it to Nambu Wastewater Treatment Plant in sunny weather, clean the water and discharge it to Tokyo Bay.
In addition, the upper part of the water pond is open to the public as a park with a view of the sea.
