Superior sanitary network attracts major investment

A small city in central Poland is gearing up to upgrade its water supply and sewage system. Work will involve construction of new facilities such as purification plants as well as the extension or modernisation of various pipelines, networks and treatment plants.

The project is EU co-funded and scheduled to last 36 months. At completion it will provide some 68 400 people in the area with a first-class new sanitary network.

Overhauled waste water system

The city of Piotrkowsko Trybunalski in Łódź Province is located in the heart of Poland. Known for being a key Polish logistics centre, it has a population of around 80 000.

The project to modernise and extend the city’s waste water treatment plant originates from the need for a complete overhaul of the area’s sanitary system, in line with the latest EU and national quality standards for water supply and waste water services.

Most of the investment will go into ensuring an improved quality of the surface water and protecting underground water resources. By the end of 2014, the project aims to have modernised the city’s water purification plant and modernised its waste water treatment plant. It will also have overseen the construction and renovation of sanitary, combined sewer, water supply and rainwater pipeline networks.

The project covers the city and various adjacent towns, including Wola Krzysztoporska, Sulejów, Grabica, Moszczenica, and Rozprza. It will be carried out in the part of the agglomeration within the administrative borders of Piotrkow Trybunalski city.

Meeting EU standards

The average capacity of the modernised and extended water purification plant is expected to increase from 7 000 m3/day to 12 000 m3/day, while the newly built water supply pipeline will cover a distance of 5.7 km. The overall length of the pipeline network to be modernised is half a kilometre.

The longest pipeline to be built is for the sanitary network, covering 17.7 km. It will function under gravity pressure and include pumping stations, drains and a damper chamber. Both the rainwater pipeline network and combined sewer system are to be modernised, the latter over 13.4 km.

The city’s waste water treatment plant will be modernised and extended, increasing capacity by around 25%. It will include a collector for treated wastewater on the Moszczanka River and sludge-processing technology. There will also be a renovated treated waste water outlet, with a 12.9 km pumping pipeline and 6.7 km outlet canal to the river. Dewatered sludge will be used for local landfill reclamation.

Expected benefits of the project include a full sanitary network for 91% of the population. This will increase to 98% after the planned change to the city’s administrative borders.
