====Borehole Information and Database====
  
Collecting information on newly drilled boreholes is done through drilling contractors, who are obliged to return borehole completion forms quarterly to the Directorate of Water Resources Management (DWRM) for each borehole drilled, with a summary of key borehole information. This information is stored in the National Groundwater Database (NGWDB). The NGWDB generally contains information only on boreholes deeper than 30 m. Shallower boreholes and wells are not generally recorded, as they are not generally given a national borehole number. A hard copy of the drilling completion reports is also stored at the DWRM offices in Entebbe. A summary of the NGWDB is given in [http://www.mwe.go.ug/sites/default/files/library/Consolidated%20Hydrological%20YearBook%201978-2014%20for%20Uganda.pdf MWE] (2017).

Collecting information on newly drilled boreholes is done through drilling contractors, who are obliged to return borehole completion forms to the Directorate of Water Resources Management (DWRM) for each borehole drilled, with a summary of key borehole information. In most cases, the returned forms are accompanied by additional supporting information in the form of a completion report, which can include siting information, adrillers log, construction data, pumping test data, water quality data and pump installation data. If the summary forms are not fully completed or the information needs to be checked, this accompanying information can be vital.

Drillers must request DWRM 'national borehole numbers' from DWRM. These numbers are usually only allocated to boreholes deeper than 30 m, although some shallow boreholes may be given a number. In general, dug wells, hand augered wells and most boreholes shallower than 30 m are not given a national number, but instead usually receive a local District-based number. Most shallow wells are not, therefore, recorded at a national level.

====Groundwater Monitoring====
+
Drillers are required to submit completion forms (and any reports) to DWRM at the end of each quarter for boreholes drilled in that quarter. This information is then entered in the national groundwater database (NGWDB). The NGWDB generally contains information only on boreholes deeper than 30 m - shallower wells are not generally recorded, as they are not generally given a national borehole number. A hard copy of the drilling completion reports is also stored at the DWRM offices in Entebbe.
 
 
There is a national groundwater monitoring network, which in 2017 consisted of 55 boreholes: 23 were already operational and 23 were newly drilled and awaiting instrumentation. Some of the monitoring boreholes are sited close to abstraction boreholes to monitor the effects of abstraction, but most are sited away from any major groundwater abstraction in order to monitor natural groundwater level fluctuations. At 21 of these sites there is also a rain gauge. An overview of groundwater monitoring is given in [http://www.mwe.go.ug/sites/default/files/library/Consolidated%20Hydrological%20YearBook%201978-2014%20for%20Uganda.pdf MWE] (2017]).
