Prevention of Garbage dumping from bridges into River Tapi at different locations.
Surat Municipal Corporation is committed to ensure that the river Tapi within the jurisdiction of SMC remains free from Invasive Flora & Vegetation like Water Hyacinths, Hydrila& Algae etc. and in the same context, measures taken by SMC are as under:
One deweeder machine has been procured on the permanent basis by the SMC in 2007 since than, the machine is being deployed in river stretch for the removal of water weeds during non-monsoon season.
Additional two deweeder machines are intended to be procured by SMC for which estimates/tendering procedures are going on. Moreover, as per requirement, deweeder machines are also hired on rental basis every year to keep water body vegetation free.
Fishermen/ boatmen living within city are also being engaged every year for removal of vegetations on manual basis. Required manpower, boats, swimmers with necessary machineries are deployed every year for the removal of vegetation from river Tapi
particularly the surrounding area of water works, Ghats, Ovaras and also from near gates of Weir-cum-Causeway.
SMC has constructed floating MS- fabricated structures and deployed in the surrounding of Intake well so as to restrict vegetation ingression along with water flow.
Floating Aerators are deployed near intake wells during non-monsoon season for enhancing dissolved oxygen level and removal of unwanted gases from water body.
Moreover, during last summer in 2018, two major programmes were under taken by SMC and State Government of Gujarat.
In order to make the vegetation removal campaign more aggressive, Tapi Shuddhikaran Abhiyan was taken up from 25/03/2018 to 17/04/2018 wherein besides deweedeer machine the other machines like Poclain, JCBs, trucks etc. were deployed and significant
amount of vegetation was removed from the river. Citizen engagement was also sought during this movement.
Larger campaign was taken up bwith the help of all stakeholders under the name of SujlamSufalam Jal Abhiyan by Gujrat State Government from 1st to 31st May, 2018 wherein eye catching quantity of vegetation was removed from river Tapi.
Total quantity of vegetation removed from river Tapi by SMC is about 3,56,042 cum (approx.) from year 2007 upto 31.05.2018.
Various measures have been taken by SMC to stop discharge of Waste water and solid waste in River Tapi like installation of screen/Jalis at various outlets of City.

Present condition of various existing Sewage Treatment Plants for SMC area in terms of sewage flow, incoming sewage characteristics and effluent characteristics have been discussed under this section.
The Sewage Treatment Plants that that will receive flow from the drains to cease the drains from discharging untreated sewage are enlisted below.
Bhesan Sewage Treatment Plant was commissioned in 1995. The current capacity of the plant is 100 MLD. The 60 MLD plant at Bhesan, commissioned in 1995, is based on Conventional Activated Sludge Process. It was designed to bring down BOD and SS values to 20 mg/L and 30 mg/L respectively. The plant was augmented in 2009 to cater 100 MLD incoming sewage.
Moreover, taking into consideration various sewerage augmentation works, it is proposed to upgrade and augment the plant up to 200 MLD. Tender for the same work is released. This shall aid in taking up additional sewage. The degree of treatment for the plant shall be up to BNR (Biological Nutrient Removal) level. At present the 100 MLD treated sewage is being disposed into the Tena creek, same practice shall prevail after augmentation and upgradation of the existing plant.
Singanpore Sewage Treatment Plant was commissioned in 2003. The current capacity of the plant is 155 MLD. The 100 MLD plant at Singanpore, commissioned in 2003, is based on Conventional Activated Sludge Process. It was designed to bring down BOD and SS values to 20 mg/L and 30 mg/L respectively. The augmented 55 MLD plant is based on Sequential Batch Reactor (SBR) technology. The treated sewage parameters for the 55 MLD plant is- BOD 10 mg/L and SS 20 mg/L.
Moreover, taking into consideration various sewerage augmentation works, it is proposed to upgrade and augment the plant up to 255 MLD, this shall aid in taking up additional sewage. The degree of treatment for the plant shall be up to BNR (Biological Nutrient Removal) level, bringing down BOD and SS up to 5 mg/L. At present the 155 MLD treated sewage is being disposed into the River Tapi.
Bhatar Sewage Treatment Plant was commissioned in 1999. The current capacity of the plant is 162 MLD but it is operating at 140 MLD, so it has a capacity to take up additional sewage load. Initially, the 120 MLD plant was based on Conventional Activated Sludge Process. The plant is based on Sequential Batch Reactor (SBR) technology. The plant is proposed for augmentation of 115 MLD making it total of 277 MLD capacity.
The degree of treatment for the plant is up to BNR (Biological Nutrient Removal) level, bringing down BOD and SS up to 10 mg/L and 20 mg/l respectively. The treated sewage is disposed into nearby Kankara creek.
Gavier Sewage Treatment Plant was commissioned recently in 2016 with a capacity of 53 MLD. The plant is based on Sequential Batch Reactor (SBR) technology with Fine Filtration.
At present, sewage flow as low as 16 MLD reaches the plant. Therefore, it has a huge capacity to take up additional incoming sewage. The plant is designed to deliver treated sewage with BOD less than 5 mg/L and SS less than 5 mg/L.
In the premises of Surat Urban Development Authority (SUDA), fourteen nos. of Sewage Treatment Plants are to be constructed by Surat Municipal Corporation.
