==Construction, operations and maintenance==
Taps are used throughout the day. They should not be left open or leak, otherwise mud and pools will form, which must be avoided. The tap and site must be cleaned regularly and the drain inspected. In case of leakage, a rubber washer or other part of the tap may need to be replaced. Any structure on the tap site and drainage system may need to be repaired. Occasionally, the service pipe, fittings and accessories may leak and need to be repaired or replaced. O&M of the domestic connection are carried out by the household itself, or by a community water committee. When water is scarce, or if the pressure is too low in part of the network, the water committee has to motivate users to limit their water use, or create conditions that will induce users to reduce water consumption (e.g. a tariff structure that discourages excessive water use).
'''Potential problems'''<br>
— leaks may not be repaired and water will be wasted;
— if too much water is lost from the system, or if water becomes scarce, it may be difficult to ensure that everyone has water, which could lead to the inequitable distribution of water;
— initial costs for household connections are higher, and it is complicated to maintain the distribution network.
==Costs==
'''Initial cost:''' Depends on factors, such as whether the domestic connection extends into a house, the type of piping material used, whether PE or PVCu pipes are available locally, etc.
