İSKİ's “Drinking Water and Sewage Master Plan” has been announced, which will ensure that sufficient water, wastewater and rainwater services are carried out in a sustainable manner in Istanbul until 2053. New sources were identified for the city's increasing water needs. According to this, 2053 percent capacity increase will be made in water supply until 50. 91 drinking water tanks, 101 pump groups, 591 km of drinking water transmission line will be built.
With the “Drinking Water and Sewage Master Plan” prepared by the General Directorate of İSKİ, it is aimed to carry out sufficient and effective water, wastewater and storm water services in an environmentally, technical, financial and institutional manner in a sustainable manner until 2053. In addition, it is aimed to determine the investment and business policy by making short, medium and long-term plans.
26 SEPARATE REPORTS WHICH HAVE 89 THOUSAND PAGES
In this context, 34 senior academic experts from various branches, 17 international experts, 163 local experts, and 19 expert administrative personnel from different disciplines took part in the plan studies. A total of 7 workshops, nearly 200 senior management meetings, nearly 1000 technical meetings, domestic and international field/institutional reviews and trainings were held. As a result of these studies, 26.000 separate reports, each of which weighed in on an independent project, were prepared, which shed light on the planning on different subjects, consisting of approximately 89 pages.
İMAMOĞLU: WE PROMISE TO IMPLEMENT THIS PLAN
The introductory meeting of the plan was held on 23 August by the IMM President. Ekrem İmamoğlu, İSKİ General Manager Şafak Başa, İSKİ Strategy Development Department Head Prof. Dr. It was held with the participation of Tuğba Ölmez Hancı.
Speaking at the meeting, İmamoğlu said; “İSKİ Potable Water and Sewerage Master Plan lays down the necessary conditions for the proper execution of services in Istanbul until 2053. As IMM, we promise to implement this plan, and we call on our fellow citizens to be careful and to monitor us.” said…
The technical details of the Master Plan, which consists of Water, Waste Water, Treatment (Drinking Water and Waste Water), Stormwater Collection System, Streams and Institutional Structure, are as follows:
SUITABLE POTENTIAL WATER RESOURCES DETERMINED
Istanbul's population and water needs scenarios were studied according to the target year of 2053. Required water resources were determined according to high population growth and high water demand scenarios.
- Existing 17 water resource facilities, 21 potential water resource facilities, 7 planned water resource facilities were examined with hydraulic model support. As a result, although it is seen that Istanbul does not need an additional water source in the event of the Melen Dam being built, the facilities to be built according to the scenarios of precipitation reduction that may occur due to the effects of climate change have been determined.
– Among the existing water distribution system elements, 149 potable water tanks, 157 potable water pumping stations, 2.847 km of potable water transmission lines were examined with hydraulic model support. As a result of the works, 91 drinking water tanks, 101 pump groups, 591 km drinking water transmission line were planned in order to ensure uninterrupted water supply and to transform the areas fed by the promotion into a gravity system.
NEW TREATMENT FACILITIES
– For all available raw water resources, water quality assessments were made for 2013 parameters between 2020 and 160. For potential water resources, 18 parameters were analyzed and water quality evaluation was made from the samples taken from 12 points for 50 months.
– Existing 21 drinking water treatment plants were examined, additional units were planned for 8 existing drinking water treatment plants. 5 conventional drinking water treatment plants and 2 sea water treatment plants are planned.
WASTEWATER COLLECTION AND TREATMENT PLANNING
- 26 wastewater collection basins, 2.000 km wastewater collector lines and 41 wastewater pumping centers were examined with hydraulic model support.
– 55 projects were developed for wastewater collection systems. A new 623 km wastewater collector line was proposed.
– 90 existing domestic wastewater treatment plants were examined and improvement suggestions were prepared.
– It is planned to increase the capacity of 10 new medium-large scale (Advanced Biological Wastewater Treatment Plant) İBAAT, 7 medium-large scale İBAAT, and to transform 6 pre-treatment plants into BAT/İBAAT with advanced technologies.
– 71 new rural İBAATs are planned. Capacity increase/conversion of 62 existing rural WWTPs to IBAAT is planned.
– Two sludge incineration plants are planned on the European and Asian sides.
FLOOD HAZARD AND RISK MAPS ARE CREATED
– 55.950 collector sub-basins were examined with the support of hydraulic model.
– Modeled integrated with 2.190 km of existing collector streams. A sustainable Urban Drainage System structure, which includes improvement and 410 ecological solutions for 522 km of existing collectors, was proposed.
– 103 km of new collector route proposed.
– Basins and their characteristics were determined for Stormwater Lines, valley floors and streams throughout Istanbul.
– A stream inventory of 2.772 km was created for 5.247 streams.
– Stream – Stormwater integrated solution and modeling were made and flood hazard and risk maps were created. For 102 sub-basins, it was recommended to apply in 1.822 km stream.
- The necessary technical infrastructure was created for the establishment of the İSKİ Flood Prediction and Early Warning System (ITEUS).
