180 MLD Sewerage Treatment Plant At Pirana

Author:

CLIENT : AHMEDABAD MUNICIPAL CORPORATION

PROJECT SUMMARY :

East Ahmedabad is mainly an industrial area. It is a rapidly developing side of the city. With the population of Ahmedabad projected to be 11 million by 2021 AD, Ahmedabad Municipal Corporation decided to extend its sewerage system. Hence MMCPL was employed to design a 180mld capacity STP( Sewage Treatment Plant) in Pirana area. MMCPL was involved in preparing detailed project report, getting approval from JnNURM , preparation of tender document, proof checking of designs provided by EPC contractors and overall management of project.

The STP is based on Activated Sludge Process with fine bubble diffused aeration system. By providing treatment, facility pollution caused due to disposal of untreated sewage in River Sabarmati will be stopped and wastewater will be used for irrigation. It is India’s first STP with PLC (Programmable Logic Controller) SCADA ( Supervisory Control & Data Acquisition) system with auto operation. The STP is capable to generate about 1.2. MW electricity by providing additional Biogas Engine System, which is self sufficient to make the STP “energy-free”.

PROJECT OUTCOME:

As a result of the work done by MMCPL,  Ahmedabad Municipal Corporation has prioritized the implementation of project and commissioned the project.
