Yesterday 30 September 2026 I signed and submitted the drawings design for DPHE SD-16 project designed for water supply at different pourashova namely- Dinazpur, Rangpur, Bogura, Jhenaidah, Jessore, Shyamnagar and Mymensingh. This project financed by World Bank will help to uphold the city life with pure drinking water round the year.

We did the electro-mechanical system - water pump, piping, solar, water ATM, electrical power design, SCADA. It is specially designed with 60 MLD & 30 MLD SWTP at Bogura and Shyamnagar respectively. In other pouroshova there is PTW to supply water to the water supply network through OHT.

The electro-mechanical design report that includes the pump head calculation, brake horse power and motor power calculation, friction-loss calculation by Hazen-William formula, the pipe dia calculation by continuity equation. It also includes the electrical design- the load demand, SLD, power supply source, the transformer, the rooftop solar, the emergency generator etc.

I thank my office team, especially Engr. Sharif Al Mahmud, Engr. Parvez, Sadiq, Khadimul for their support. Alhamdulillah.
