Water requirement for the facility may be worked out and enough storage for ½ day operation is to be kept in storage. If municipal water supply is reliable, the toilet blocks may have underground sump that can store half a day requirement and overhead tanks for another half. If municipal water supply is not available, toilet block may have its own water source and pump with or without underground sump

Alternatively, a hand tube well can be used for storing water in an elevated (not overhead) tank. To minimize the wastage of water, self-closing water taps shall be used. The pans must be of Pour Flush (PF) design i.e. with a steep slope. Traps shall be of a 20mm water seal. (Use of 50mm water seal traps will require more water for flushing.)
