According to the "Bombay City Gazetteer" published in 1909, these tanks were often very low and had to be replenished by sinking new wells. In 1846, the city faced an acute water shortage following which Framji Cowasji sank three wells in its gardens to provide water by steam machinery. Later in 1856, the city faced a severe drought, and an edict was set out relocating all cattle to Mahim, which was the periphery of the city at that time. Thousands would gather daily around the tank at Esplanade to collect water, while the government brought thousands of water drums from far off distances to empty into wells at Bori Bunder, Chinch Bunder, and Dongri. After a regular water supply to the city was established from the Vihar and Tulsi lakes, the tanks were declared redundant. They soon became a breeding ground for mosquitoes and consequently were filled in. The famous Gowalia Tank Maidan is on top of the original tank. USS Hayler  USS "Hayler" (DD-997), the last "Spruance"-class destroyer, was the first ship of the United States Navy to be named for Vice Admiral Robert W. Hayler (1891–1980). For fiscal year 1978, Congress authorized the production of two additional "Spruance"-class destroyers, though they funded only one. These were intended to be built as helicopter destroyers (DDH), provided they would not cost more than a standard "Spruance"-class. Litton-Ingalls completed sketch design work for DDH-997, which moved the helicopter deck aft, stretching the length of the hangar and displacing the Sea Sparrow launcher to the top of the hangar. The design would have accommodated two SH-3 Sea Kings or four smaller SH-60 Seahawk or SH-2 Seasprite helicopters. While the prospective DDH-997 probably wouldn't have cost much more to build than a standard "Spruance"-class, the detail design and engineering work required before the ship could be built would have been substantial (similar work for the "Kidd"-class cost $110.8 million). This raised the cost of the DDH substantially above a standard "Spruance"-class destroyer. While this additional cost might have been justified if the DDH was going to enter series production, it was difficult to justify for a single ship. Accordingly, the Navy built "Hayler" to a similar design as the rest of the class, while incorporating some systems from the Ticonderoga Cruiser and Kidd (Ayatollah/Dead Admiral) Destroyer designs.
