A pumping chamber 202 includes a pump 212 and an integrated separator 204. The separator may be formed within the pumping chamber by means of at least one baffle 210. Preferably the pumping chamber also includes an integrated sealed valve chamber 304 including at least one valve 222, 322 configured to control discharge of fluid out of the pumping chamber. Preferably the pumping chamber is formed from material such as glass reinforced plastic. Preferably there is an access aperture 306 for the at least one valve within the integrated sealed chamber. Advantageously the pumping chamber results in reduced excavation time, requires fewer installation materials and takes up less underground space. |
